Frequently Asked Questions

All five of our commercial brands sit under Alkur Kapı Sistemleri A.Ş.: ALKUR HPVC (rapid PVC doors, standard and cold storage), r-tec (automatic doors, door operators, barriers, control boards and EV chargers), NORMPANEL (sandwich panels and accessories), NORMTOR (sectional doors — industrial, garage and full vision variants) and NORMDOCK (loading dock levelers and shelters). All production is carried out at our Hendek/Sakarya facility; the brands differ only by application area.

Industrial sectional doors are designed for intensive operation in logistics, manufacturing and warehouse buildings, offering wide openings and a reinforced frame structure. Garage sectional doors are optimized for residential and light commercial use; the size scale is narrower and panel options are aesthetics-focused. Full Vision is customized for spaces where transparency is expected, such as showrooms, car galleries and control cabins, with aluminum frames and wide glass panels. For correct variant selection, evaluate frequency of use, opening size and aesthetic expectations together.

HPVC is used in points where indoor-outdoor passage is frequent, temperature or hygiene separation is required, and forklift traffic is heavy. Typical applications: food, pharmaceutical and cosmetics production areas, cold storage facilities (cold storage special variant), retail logistics centers and parking lot entrances/exits. Thanks to its high opening/closing speed, it reduces energy loss and dust/insect transition; when placed in the same opening as a sectional door, it is generally positioned as a 'rapid transition' door in front of or beside the sectional.

In most logistics projects, the two are planned together at the same loading door: the leveler closes the level between the truck bed and the building floor, while the shelter isolates the gap between the vehicle and the building. This set must be dimensioned together at the project stage; leveler capacity and shelter type are selected based on truck bed size and the height of the loading platform in the building.

There are two main lines: industrial and garage; panel thickness and density vary based on the application purpose. In the industrial line, options are available for projects where cold storage and fire resistance stand out; the garage line focuses on aesthetic patterns and color variations. Specific thickness, thermal conductivity coefficient and fire class information is listed in the technical specification and brochure on the panel product page.

Industrial sectional; designed for wide openings on reinforced rails with typical 40 mm sandwich (PU 40 kg/m³ filling), U ≈ 0.604 W/m²K insulation, R'w ≈ 26 dB sound reduction and the SIRIUS motor series. The Garage line is optimized for residential use with 460-610 mm panel height options, EN class 3 wind / class 2 water insulation, plexiglass window and service door options. Full Vision is customized for openings where transparency is sought such as showrooms, car galleries and control cabins, with a 1.3 mm aluminum profile and 3 mm plexiglass panel composition, and is produced up to a maximum opening of 5×6 m.

NORMPANEL is offered in two main families. The Industrial line is the basic sandwich panel for warehouses and production — with flat and classic embossed surfaces, 500 mm and 610 mm panel height options, and a wide RAL range. The Finger-Protected line has a special profile at the panel hinge that prevents finger pinching and is preferred as a safety standard in residential, complex or facilities with high user density. A total of 16 SKUs (8 surface codes × 500/610 mm height) is selected on a project basis with the color + surface + dimension matrix.

Capacity defines the minimum safety limit for the maximum load (forklift + load) that will pass over the leveler. For operations working with standard pallets and light forklifts, 6 ton is generally sufficient; for facilities with heavy forklifts (4-5 ton class + load) or container traffic, the 9 ton class is selected. The NORMDOCK loading dock leveler is offered in standard platform sizes of 2000 × 2500 mm and 2000 × 3000 mm, with single-flap or three-flap lip options. For correct capacity selection, the forklift technical label and the daily load profile must be shared at the quote stage.

The single-flap (telescopic lip) extends telescopically from the leveler end with a single lip that sits on the vehicle's interior floor, smoothing small variations in bed distance and providing a longer reach. The three-flap (hinged lip) is a classic hinged lip at the end of the leveler, with simpler mechanics and lower cost — suitable for fixed bed sizes. Single-flap is more often preferred in facilities with containers and variable bed heights, while three-flap is more often preferred at standard loading points with fixed truck fleets.

The opening speed of HPVC doors is selected based on motor torque, curtain weight and the number of passes required per second. Low speed (~0.5-0.8 m/s) is an economical solution for medium openings and normal traffic, medium speed (~1-1.5 m/s) is standard industrial internal zone transition, and high speed (~1.5-2.5 m/s) is for points with heavy forklift traffic and where energy/hygiene loss is critical. In the high speed class, an inverter (r-tec FU) and special motor set are required. The ALKUR HPVC line supports different speed classes using the RAPID 35-180 motor series with the r-tec inverter kit.

DINAMIX 4/5/6/7 is a barrier family designed for different lane widths with 4 m, 5 m, 6 m and 7 m arm lengths respectively. All work with a common 230 V supply, 24 V control and ~190 W motor power. DinamixBar 4/5/6/7 maintains the same length range while adding an integrated LED bar on the arm — preferred at parking lots and complex entrances where nighttime visibility and premium presentation are desired. WM 3000 is a wall-mounted compact variant complementing the family. The entire family is covered under the CE certificate GCN-352/23 (2023) within the r-tec brand.

First, the lane width to be closed is measured, and barrier arm length is determined with an approximate 10-15% tolerance; for example, DINAMIX 5 (5 m arm) is suitable for a 4.5 m single lane. For two-lane or wide parking entrances, models with 6-7 m arms (DINAMIX 6/7 or DinamixBar 6/7) are recommended. In facilities with high cycles per hour, the motor class and mechanical wear limit are also checked. For heavy traffic, induction loop detectors and a safety photocell on the opposite lane are planned together.

Swing gate motors are used in single or double hinged gates and require an opening area in front of the gate. In the r-tec line, the KING 1000/2000 and COUPER 24 models cover different leaf weight/length classes. Sliding motors operate on gates that slide horizontally on a rail, do not require an opening area, and are preferred for wide openings and sloped ground. In the r-tec sliding gate line, the LINEAR 40024 and compatible models are selected based on leaf weight and daily frequency. Sliding is generally suitable for villa, factory and complex entrances; swing is suitable for small complexes/villas.

The r-tec automatic door is offered with the R2 control board in four main door types: double-leaf (two leaves slide horizontally at the same time), single-leaf (single-direction sliding), telescopic (leaves that collect in two stages in each direction — for wide passage at narrow openings) and revolving door (special air-curtain applications). There are three chassis variants: standard aluminum, telescopic chassis, and hermetic chassis (food, pharma, hospital). The motor is 100 W DC, 230 V / 24 V supply, IP23, and operates with a 5-mode selector (automatic, always open, night lock, etc.). It is the standard solution at entrances with heavy pedestrian traffic and aesthetic expectations.

Full Vision is designed for openings where visual display is a priority, with a composition of 1.3 mm aluminum frames and 3 mm plexiglass panels. Typical applications: car gallery storefronts, showrooms, commercial storefronts and control cabins. It is produced up to a maximum opening of 5 × 6 m and is automatically operated with the r-tec 10024 motor series. The double-skin plexiglass variant is preferred in projects where higher thermal insulation or impact resistance is sought.

At minimum, the following three measurements are required for production: net opening (width × height), header (top clearance) and side jamb clearances. In addition, the interior depth (especially for the rail layout in sectional doors), floor levelness and the location of the electrical supply are important for the production and installation plan. If possible, sharing interior and exterior photos of the opening and, if applicable, the dismantling plan for the existing door speeds up the process.

Product type (sectional/HPVC/loading/automation), opening dimensions, quantity, place of use (warehouse, cold room, food production, etc.), desired automation and accessory set (motor, control, photocell, safety edge, etc.), project location and delivery schedule. Custom color, panel class or size requests outside the standard line must be specified separately; for export projects, country and Incoterm information is also collected before the quote.

Yes. Although a standard size scale is defined for each line, project-specific custom dimensions constitute a significant part of our production. For non-standard requests, a technical approval process applies: after the dimensions, panel/profile suitability and motor selection are confirmed by engineering, the quote is finalized. For this reason, sharing custom-sized projects early in the planning phase positively affects the delivery time.

Production time on the standard line varies depending on the model and seasonal load; a written time frame is communicated to our dealers at order confirmation. Exceptional requests such as custom color, panel class, size, and export packaging affect the time. For an exact delivery date, work with your sales representative; the sales line you can reach via the contact page is separate for domestic and export.

Net opening (clear opening) is the actual free dimension that the vehicle or forklift will pass through when the door is open. Structural opening is the inner dimension of the frame or formwork in the building and is larger than the net opening because the door frame fits into this area. Niche is the recess formed in the inner wall when the opening is not on the same plane as the inner-outer façade. Side room is the space next to the opening where the door frame and mechanism will fit; headroom is the space between the upper level of the opening and the ceiling. These four measurements must be shared separately at the quote stage.

The most frequent mistakes we encounter: sending the structural opening instead of the net opening, forgetting the ceiling clearance (headroom), late realization of insufficient side room, not measuring floor slope (critical for loading dock leveler), not sharing the voltage and fuse capacity of the existing electrical supply, not reporting that the opening has different widths on its inner and outer faces. If possible, on-site measurements should be double-checked with two people using a laser distance meter + tape measure; net opening and niche photos catch these errors early.

Dealer price is the standard list price of our authorized dealers with whom we regularly do business and operates with our line-based seasonal discount policy. Project price is specifically calculated by our project team based on product quantity, technical customization and delivery conditions for one-time, large-volume special projects and tenders. Export price is worked out separately based on country, Incoterm (FCA, CIP, etc.), packaging and document package. All three price segments are managed by our sales team; end-user prices are not given directly without a dealership agreement.

Standard color is the 5-6 RAL and surface combinations defined for each line; no additional production time is required. Custom RAL is the selection of a single RAL code outside the standard palette and requires an extra paint batch and affects production time. Double-sided means a request for a different RAL code for the inner and outer surfaces of the door (e.g., outer surface RAL 9006 aluminum gray, inner surface RAL 9010 pure white) and requires two separate paint processes. If a different RAL color is requested for accessories (header profile, rails, motor cover), this must also be specified separately.

A typical door order package includes — besides the main leaf, frame, rail, motor and control — accessories selected based on the application. The most frequently added: plexiglass or glass window (on the panel), service door (a small pedestrian door opening within a large door), photocell set (lower-level passage safety), safety edge (bottom panel pinch safety), flasher/signal light and safety lock. For NORMTOR sectional, a reference accessory list of 27 components is available; each accessory must be enumerated in package detail at the quote stage.

Domestic delivery is priced separately as standard road transport to the dealer or project address; the trip is planned based on the dealer's warehouse location and tonnage. Export delivery is finalized by contract under Incoterms 2020 as FCA Hendek (ex-works), FOB port, CIP destination, etc. Packaging type (pallet, crate, container), customs document package (CE declaration, invoice, packing list, certificate of origin) and insurance liability vary based on the selected Incoterm. All documents are finalized with dealer or customer approval before shipment.

For orders that have not entered production, revisions (size, color, motor change, etc.) are generally possible; our team evaluates the revision's impact on the production plan and shares the new delivery time. For orders that have entered production or have been prepared in custom sizes/RAL, cancellation may not be possible or a cancellation fee may apply. Orders requiring rapid procurement such as spare parts do not accept revisions for regularity. Revision requests are processed when sent in writing (via email or the dealer panel).

Core standard line products (spare parts, panel surfaces, some r-tec motors and control boards) are kept at the factory warehouse for stock delivery. Products such as doors (sectional, HPVC, full vision) and loading equipment (leveler, shelter) enter production for each order based on dimensions and customization. Order type and delivery time are shared at order confirmation by your sales representative in the dealer information note.

Typically the following documents are prepared for an export shipment: CE declaration of conformity (depending on the product line, e.g., EN 13241-1), ATR (EU countries) or EUR.1 (preferential trade), certificate of origin, commercial invoice, packing list and, if necessary, EAC certificate (Russia and Eurasian Customs Union). In addition, project-specific quality control reports and test certificates may be requested for tender files or public projects. The export sales team finalizes the document list with the customer's customs broker at the contract stage.

Measurement and site survey are carried out by your own authorized technical team running the project; Alkur does not provide site visits or on-site surveys. For an accurate quote and production, it is enough to send us the net opening dimensions, number of openings, door type and project location via the contact page or through your assigned sales representative; net opening and niche photos speed up dimension verification. For overseas projects, the information flow is coordinated with our export sales team.

The opening must be clear (formwork, frame or temporary cover removed), the header and frame walls must be at their final level, and the floor must be even and at the same level in the area where loading will take place. The electrical supply must be left near the installation point at the voltage and fuse capacity required by the door type. In special spaces such as cold storage, food or pharmaceutical, hygiene and temperature conditions must be maintained during installation.

For each product line, the technical specification and installation guide of the relevant model is the primary reference; these documents are available in the downloadable list on the product pages. For visual confirmation, the official on-site videos provided on the product page are used. Third-party videos or general internet sources do not constitute a basis for the procedure; always proceed from the manufacturer document that matches the model one-to-one.

Spring balance and mechanical balance in sectional doors, hydraulic adjustment in loading dock levelers, and control parameters in automation lines carry serious injury risk and should only be performed by a trained installation team according to the procedure in the relevant guide. Do not enter adjustment values by guessing; use the values from the relevant model's specification and record the commissioning report.

A sectional door requires headroom for the curve of the top rails and side room where the motor and side parts will fit. With a standard torsion spring system, typical minimum headroom is planned as 300-350 mm, and side room as 90-120 mm on each side; for projects with low ceilings or high lift needs, special rail types such as Low Headroom, Vertical Lift or High Lift are used, with different minimum dimensions. Before each project, the rail option in the model's technical specification and the required clearance values must be verified.

For a standard 230 V single-phase motor, a typical 16 A fuse, 3 × 2.5 mm² NYM cable and proper grounding are required; for a 380 V three-phase motor (especially heavy industrial doors or HPVC inverter supply), a 25-32 A fuse and 4 × 2.5 mm² (or 4 × 4 mm² if necessary) cable are required. The panel should be near the door opening, and emergency stop and grid disconnect switches should be planned in accessible positions. Grounding must absolutely be done; operating without grounding seriously affects motor safety and control board life and voids the warranty.

For a cold storage door (sectional, HPVC or combination), seals, panel insulation thickness and sealing performance are selected above standard. During installation, the indoor temperature of the room must be continuously maintained, and condensation management at panel hinges and the drainage channel must be checked. The HPVC cold storage variant prevents moisture and low-temperature freezing problems with options such as heated seals or double-skin curtains. Two annual maintenance visits are recommended at cold storage operations; seals and condensation paths are inspection items.

The FU inverter converts a 220 V single-phase supply to 3 × 230 V three-phase output to drive HPVC high-speed motors (typical 2200 VA capacity). For connection, 220 V phase/neutral/ground is connected to the grid input terminals, the three motor phases and the encoder/limit switch wiring on the mechanism are connected to the motor output terminals. Maximum speed, brake and ramp times are adjusted with trimpots based on door weight; the DIP switch combination defines the door type (HPVC, cold storage, etc.). Trimpot and DIP adjustment values should only be set by a trained team within the range in the model guide.

220 V single-phase industrial door motors are mostly used for compact and medium-opening doors and adapt to standard 230 V phase/neutral/ground supplies ready on-site. 380 V three-phase motors are preferred for heavy industrial doors, high-torque applications and heavy traffic requiring frequent cycles, offering higher power density. On three-phase lines, the r-tec I380 control board (1.5 kW, current and phase protected) operates as a standard package. Incorrect phase sequence reverses the motor's rotation direction; it must absolutely be checked at commissioning.

The barrier body is fixed on a reinforced concrete base typically 300-400 mm deep and sized according to the motor class (e.g., 400 × 400 mm). Anchor studs are embedded in the concrete, and the ground surface must be even at the same level as the barrier chassis base. The electrical supply (230 V phase/neutral/ground) and, if required, induction loop detector cables are routed in pipes or conduits within the concrete. If installation is performed before the concrete curing period is complete, base deformation reduces motor life; installation is started after a minimum 7-day curing period.

The loading dock leveler is placed in a reinforced concrete pit opened in the building floor. The pit size is determined in the manufacturer drawing based on the selected leveler platform size (e.g., for a 2000 × 2500 mm leveler, approximately 2100 × 2600 × 600-650 mm deep pit). Water drainage at the pit base, anchors and connection studs on the side walls, and infrastructure for the hydraulic unit and control panel at the edge are planned. The hydraulic connection is made between the leveler cylinder, unit and solenoid valve according to the manufacturer's diagram; tightness and leveling are tested at commissioning.

Automatic pedestrian doors operate with a fixed aluminum chassis profile that holds the top rail. The chassis is fixed under the header or on the ceiling with suitable anchors; the gap between the two skins is planned to be sufficient for leaf movement. Electrical infrastructure typically requires 230 V phase/neutral/ground and a hidden cable passage next to the R2 control board housing on the door. Cables for the sensor (radar or active infrared) and photocell are pulled during installation; having a ready cable conduit on-site shortens installation time.

Commissioning consists of mechanical and electrical tests. On the mechanical side: spring balance, cable/chain tension, seal tightness, door standing balance test, opening-closing time, and trigger test of safety components (photocell, safety edge, emergency stop). On the electrical side: control coding, verification of no error codes, limit switches and manual recovery system are tested. After all tests are completed, the customer is provided with the commissioning report, user guide, warranty document and maintenance schedule; the report is kept in the dealer's contract archive.

Within the first 24 hours, the door should be operated at normal operating frequency and friction, sound, heating or leaks should be observed. At the end of the first week, bolt and nut connections should be rechecked for torque (especially anchors and spring shafts), and seal placement, photocell alignment and control range verified. If a hydraulic system is present (loading dock leveler), oil level and leakage are checked. Unusual vibration, noise or alarms observed in the first week should be reported to your authorized technician; instead of guessing parameter changes, guide-based checks should be performed and, if necessary, the product delivered to our manufacturer technical service.

Reach our technical support team

The general principle is at least one full maintenance per year on the industrial line, and a half-year interim check on doors with heavy traffic. Maintenance scope includes: torque of mechanical connections, spring and cable wear, rail and roller check, seal and brush set, motor and reducer oil/level check, and testing of controls and safety components (photocell, safety edge, emergency stop). In cold storage and food lines, seals and hygiene surfaces are additionally checked.

First, identify the model and serial number from the door/motor label; bring the door to a safe position without disabling the safety components. The initial intervention is performed by your authorized technician based on the fault table in the relevant model's guide. In unresolved situations, contact our manufacturer technical support through your sales or service representative; since our technical service only handles products delivered to us, sharing the label photo, error code (if any) and a brief incident history in the fault record shortens the resolution time.

Reach our technical support team

The standard manufacturer warranty covers manufacturing and material defects, and its duration varies by contract and product line. Typical exclusions: third-party parts/installation not approved by the manufacturer, disabling safety components, loads outside the user guide, impact damage and disasters. Warranty claims are always handled through the relevant dealer or corporate customer channel; direct end-user requests are not accepted.

From the door or motor label: model, manufacture/serial number and, if possible, commissioning date. The set in which the part is used (spring, cable, roller, profile, seal, etc.) and its position on the line must be clarified. Do not seek compatibility with equivalent commercial parts; substitutions outside manufacturer-approved parts may compromise specifications, safety and CE compliance, and will void the warranty.

Reach our technical support team

Typical industrial door maintenance includes: spring/counterweight balance, cable or chain wear, rail and roller condition, hinge/articulation lubrication, seal and brush set, panel deformation, motor noise and heating test, reducer oil level, control fault log, photocell and safety edge verification, emergency stop trigger test, accuracy of limit switches, and ground line measurement. For loading dock levelers, additionally hydraulic unit oil level, cylinder seal and lip hinges are checked. The maintenance report is archived at the dealer in a standard format.

The most frequently encountered exclusions: spare parts or third-party installations not approved by the manufacturer, disabling safety components (photocell, safety edge, emergency stop), operating the door/motor in an environment outside the user guide (e.g., excessively dusty, muddy, or chemical vapor environments), impact, vehicle collision or natural disaster damage, unauthorized changes to factory settings, control board burnout due to electrical supplies not protected against voltage fluctuations. Failure to perform annual periodic maintenance may also affect warranty claims in some situations.

The standard manufacturer warranty varies by line and product type. As a typical range: motor and control board 12-24 months, mechanical components (panel, rail, frame) 24 months, hydraulic system 24 months. Consumable parts such as springs, cables, seals and brushes are warranted up to a specific number of cycles (e.g., 25,000 - 100,000 cycle range); replacement beyond this is considered normal wear. Because specific periods vary by contract and product category, exact warranty periods are stated in the dealer's quote/contract document.

Some situations can be resolved by your authorized technician before requesting service: checking the main fuse on the panel, reading the warning LED or error code on the door/motor, replacing the remote control battery, cleaning the photocell (dust and spider webs are the source of most errors), removing obstacles in front of the door, bringing the door to a safe position with the manual recovery system. These checks are described in the "troubleshooting" section of the model's user guide. If the error code indicates a mechanical or burnt component, contact authorized service without intervening and, if necessary, deliver the product to our manufacturer technical service.

On r-tec control boards, error codes are shown as LED flashing patterns or codes on the panel display. R2 (automatic door) uses LED codes such as door/sensor error, motor encoder error. G24 (universal 24 V board) returns standard error classes such as connection, photocell and motor overload. GIGA SEDO (premium industrial control) keeps a readable error message and event history on the LCD display and supports remote reading via RS485. The meaning of each error is in table form in the model's user guide; code-table matching should be done instead of guessing adjustments.

Sectional door spring replacement is a high-risk procedure where an uncontrolled release of the torsion spring can cause serious injury. It must only be performed by a trained installation/service team, when the door is fully down, and with appropriate safety apparatus. The correct spring type (diameter, wire thickness, wind direction and length) is selected from the model's technical specification; using equivalent commercial springs disturbs balance and safety performance and voids the warranty. After spring replacement, balance and safety component tests are performed again.

Reach our technical support team

Superficial damage such as surface scratches or external coating defects can be repaired by an authorized technician with manufacturer-approved paint or touch-up kits. In cases of hinge deformation, panel bending from the center, exposure of the insulation filling, or interior sheet tearing, complete replacement of that panel (and the neighboring panel if structurally affected) is required. For repair decisions, forward detailed photos and damage dimensions to the manufacturer via the dealer or corporate customer channel. Continuing to operate the door without resolving structural panel damage wears down other mechanical parts.

Reach our technical support team

Sectional door cables (on both sides of the leaf, part of the pulley system) should be visually inspected at least twice a year: fiber breakage, crushing, coating peeling or corrosion. As industry standard, if the cable shows visible damage or has exceeded the 10,000-15,000 cycle range, both cables should be replaced simultaneously (replacing only one creates asymmetric mechanical imbalance). On chain-driven industrial doors, tension, lubrication and link wear are inspection items. Cable or chain breakage carries serious injury risk; it must not be skipped in periodic maintenance.

The HPVC curtain is typically manufactured from 900 g/m² PVC fabric and can be locally damaged by forklift impact, thermal shock or UV/wear over time. For small tears or holes, repair can be done with manufacturer-approved patch kits; however, if there is major damage in the center of the leaf or on the side edge profiles, complete curtain replacement is recommended, because the tear will widen during motion after repair. At points where impacts are frequent, curtain panels designed for easy impact repair and breakaway bottom profiles are preferred.

Before winter: seal elasticity and tightness, check for ice formation on the bottom panel during opening-closing, operation of heated seals or resistors on cold storage HPVC doors, verification that the lubricant is in the low-temperature class. Before summer: motor and control box ventilation (overheating expectation), RAL coating integrity on sun-exposed exterior panels, high-temperature durability of lubricant and seal deformation. For both winter and summer, cleaning the safety component (photocell) lenses is important. At seasonal transitions, always refer to the seasonal checklist in the model guide.

Motor selection is based on door weight, opening size, daily operating cycle count (cycles/day), environmental conditions (dust, moisture, temperature) and the desired additional safety/control functions. Our dealers recommend a compatible motor and control with the door option at the quote stage. When adding or replacing a motor on an existing door, sharing the model information from the door label and the existing electrical supply is mandatory for correct selection.

r-tec is the separate commercial brand for automation and electronic control products within Alkur Kapı Sistemleri A.Ş. It covers product families of automatic doors (pedestrian), industrial and garage door operators, garden automation (sliding + swing), barrier systems, control boards and accessories, and EV chargers. It can be offered from a single source together with door and loading projects; marketing-focused broad content and product archives are published at r-tec.com.tr. On this site, the technical summary of each r-tec model is listed on its product page.

First, verify the power supply and the fuse status on the panel; then match the warning LED or error code on the remote with the model's technical documentation. Steps such as battery replacement, code learning and returning to factory settings are described in the guide. In cases such as a short circuit, burnt component, or those requiring software/recovery, the dealer or authorized service channel should be used instead of untrained intervention.

r-tec barrier systems are used to control vehicle flow at parking lots, factory entrances and residential complex entrances/exits. EV charger products are positioned as electric vehicle charging infrastructure in commercial parking lots, office and complex projects. Both product families can be offered together with door/automation projects; for application details specific to on-site needs, you can reach our project team via the contact form.

Industrial door motors are classified by the maximum number of cycles they can perform per hour (cycles/hour) and the total life cycle. Motor manufacturers define classes such as Class 1-5 based on door usage frequency (e.g., Class 5: heavy, 100+ cycles per hour, logistics warehouse). Together with door weight, opening size, outdoor conditions and safety component load, the motor's torque and thermal protection class are determined. For correct motor selection, sharing cycle/day and cycle/hour estimates with our dealers at the quote stage directly affects motor life.

A 230 V single-phase motor offers sufficient power for medium-opening and normally cycled doors (garage, light industrial) and operates on standard home/business supplies. A 380 V three-phase motor is preferred for heavy-leaf industrial doors, heavy-traffic logistics openings and high-torque applications, offering more stable torque and lower current draw. If the site's electrical infrastructure is not three-phase, the r-tec FU inverter can produce 3 × 230 V three-phase output from a 220 V single-phase supply to drive HPVC or selected door motors. The selection is verified by engineering together with the motor class.

The rapid opening-closing performance of HPVC doors requires controlled ramping of the motor speed; a standard motor running at constant speed and constant torque cannot maintain balance in the high speed range. The FU inverter converts a 220 V single-phase input to 3 × 230 V three-phase output and supplies the motor with adjustable frequency and ramp times (typical 2200 VA capacity). Thus, startup is smoothed, deceleration is applied at the top point, shock on the curtain and mechanics is reduced, and speed and braking sequence become repeatable for each opening. Max speed/ramp is set with trimpots, and door mode is selected with DIP switches.

A typical photocell set consists of receiver (RX) and transmitter (TX) two units, placed at the same height on both sides of the door opening. The connection is made to the photocell terminal on the control board (generally as an NC dry contact input); when the beam line is broken, the board detects an "obstacle" and stops or reopens the door. The flasher is connected to the additional lamp output on the board (12-24 V or 230 V depending on the model selection) and flashes during motion. Emergency stop, safety edge and safety lock are also connected to the NC series chain to close the circuit through the board. The connection diagram is described in the model user guide with communication symbols.

The induction loop detector detects the metallic body of the vehicle with a coil placed under the ground and sends a signal to the barrier for automatic opening or to prevent closure. It is generally used for "automatic opening for vehicles without cards" on the exit lane or "lowering when a vehicle is detected during closing" safety on the entrance lane. It is not mandatory at entrances with low traffic and where user cards/remotes are always used; however, it is planned as standard at busy parking lots, highway toll booths and factory logistics gates. Coil size, number of turns and detector sensitivity vary by model.

WCU-22 is a 22 kW AC three-phase output, wall-mounted (wallbox) fixed station — suitable for daily 4-8 hour charging scenarios at offices, shopping malls, residential complex parking lots and corporate parking locations. WCU-11 Portable has portable single-phase/three-phase adapter options and is designed for plug-and-play use — positioned as a backup charging solution at construction sites, temporary operations or while traveling. Corporate projects (parking lots, commercial sites, complex management) are mostly installed with the WCU-22 fixed station; individual portable use is resolved with WCU-11.

OCPP (Open Charge Point Protocol) is the open-standard communication protocol through which charging stations talk to the back-end management platform — it enables services such as reservation, payment integration, remote start/stop and user authentication. Load management (dynamic load management) operates when there are multiple charging stations on the same building line, dynamically distributing current among stations without exceeding the building's main fuse. In corporate projects at the WCU-22 scale, OCPP integration and load management planning are evaluated by our project team together with the site's electrical infrastructure.

On garden motors, the end-stop (limit switch) defines the gate's open and closed end positions mechanically or electronically — it stops the motor at the target position. The force setting (force/torque limit) determines the motor's behavior to stop and back off in response to abnormal load and is adjusted within the scope of the EN 12453 standard as part of the safety components. Typical sequence: first, mechanical stops are positioned, then a full opening-closing in "learning mode" is performed from the control board, then the force trimpot is tested with an obstructing object and brought to the minimum required value. Instead of guessing on-site by observation, the steps of the model user guide should be followed.

For garden gate, barrier or small industrial door applications that need to operate continuously during grid outages, solar panel + battery-backed installation is possible. The 24 V DC motors (KING, COUPER 24, etc.) on the r-tec line and compatible control boards can be powered by a battery buffer, with the solar panel providing daily charging. For large openings such as NORMTOR Hangar, the 10-component r-tec automation package offers solar and battery options. When sizing the system, daily cycle count, panel power (Wp), battery capacity (Ah) and local sunshine duration are calculated together.

Yes. The license plate recognition system (Plate Recognition System / License Plate Recognition) operates on the principle of a camera placed over the lane reading the vehicle's license plate, comparing it with authorized plates in the database, and sending an "open" signal to the barrier or door control board. The dry contact input (generally NO) on r-tec barrier control boards is compatible with PTS systems; integration is planned at the project stage together with the parking management software or card access system. RFID card readers, remotes, and license plate recognition can also be set up as a combined access hierarchy.

Conformity documents (CE declaration, quality certificate, EAC, etc.) are published in the downloadable file list on the relevant product page. The validity date and revision number of the documents are on the document itself; the most current version is always the file row on the product page. For official processes such as project tender files, we recommend retrieving the latest version of the documents from the product page.

EN 13241 is the European product standard for industrial, commercial and garage doors and the technical basis for CE marking. The standard defines performance classes such as mechanical strength, water tightness, air permeability, thermal insulation, acoustic performance, opening forces and safety components (pinch protection, photocell, safety edge). The ALKUR/NORMTOR sectional door line has been tested at class 2-3 levels by SP Sweden (RISE accreditation) and the CE declaration is published with these class values. You can access the document from the downloadable list on the relevant product page.

The Domestic Product Certificate (TOBB/KOSGEB) shows the percentage of domestic value added in the product's production — the domestic share of items such as raw materials, labor, energy and depreciation is calculated. The ALKUR automatic door line carries the Turkish-made certificate with 100% domestic ratio, and NORMTOR sectional doors with 64.57% domestic ratio. The main reason for the difference is that some motor, seal and calibrated sheet materials are imported in the sectional door line. The Turkish-made certificate provides price advantages in public tenders; current certificates must be verified on the certificates page.

EAC (Eurasian Conformity) is the mandatory conformity marking for member countries of the Eurasian Customs Union (Russia, Belarus, Kazakhstan, Kyrgyzstan, Armenia). When industrial door, automation and panel products are exported to this market, the EAC certificate or declaration (depending on product category) is included in the document package. Existing EAC certificates in the ALKUR portfolio are listed on the certificates page, and their validity periods are stated on the document itself. For new Eurasian market projects, the export sales team verifies certificate validity before the contract.

Typical export document package: commercial invoice, packing list, certificate of origin (Chamber of Commerce approved), CE declaration of conformity (reference to product standard — e.g., EN 13241-1), if necessary EAC (Eurasia), ATR Movement Certificate (EU countries) or EUR.1 (preferential trade agreement countries), shipping bill (BL, AWB, CMR, etc.), and, if necessary, fumigation certificate (for pallet wood, ISPM-15). For government tenders or infrastructure projects, an additional factory test certificate or third-party quality control report may be requested. The export sales team finalizes the document list with the customer's customs broker at the contract stage.

We do not share our dealer and project references with third parties without written permission and a contract. Reference sharing for some of our projects is conveyed only in special meetings opened for the relevant customer, within the framework of an NDA or the customer's written approval. We do not produce anonymous "sector + region" examples for the purpose of providing industry information; this practice is both problematic in terms of competitive analysis and could be considered implicit promotion of the customer, so it is not our ethical preference. If you need a sectoral parity example for your new tender file, you can open an individual meeting with our project team.

Basic prerequisites for dealership: marketing and service capacity for the product line, technical team (installation and commissioning), market size and existing dealer density in the dealer's operating area, financial adequacy. The process works as a dealership application form, evaluation meeting, contract and training program. New dealers are provided with product training, sales support, brochures and digital materials. To apply for dealership, sharing your company's field of operation and existing product portfolio with our team via the contact page is sufficient.

ISO 45001 is the international standard for the occupational health and safety (OHS) management system and defines risk assessment, procedures and continuous improvement processes related to employee safety in the workplace. Alkur Kapı Sistemleri's Hendek/Sakarya manufacturing plant is certified to the ISO 45001 standard; this means that we have passed an authorized body audit for the safety of employees at the factory. The validity date and certificate number are on the document itself; the current version is published on the certificates page.

ISO 9001 is the quality management system standard applicable to all sectors. The standard requires the documentation of processes such as process definition, customer satisfaction monitoring, continuous improvement, supplier management and risk assessment. As a manufacturer certified to the ISO 9001 standard, Alkur Kapı Sistemleri operates project orders within a traceable quality system as opening, production, commissioning and after-sales support. The certificate is sufficient reference for the "quality management system" proof required in tender files.

The EU New Machinery Regulation (Regulation (EU) 2023/1230) replaces the previous Machinery Directive 2006/42/EC and becomes mandatory in 2027. The new regulation introduces new requirements in areas such as cybersecurity, AI-supported systems, remote control and digital user guides. For industrial door and automation products, safety components, conformity documentation and risk analysis processes will be updated. The transition process is being monitored by engineering for ALKUR product lines; for export projects, verify the current compliance status of sets to be delivered after the relevant date with our sales team.

Warranty is the manufacturer's obligation for free repair or replacement during the period specified in the contract for faults arising from manufacturing or material defects, and is defined within the framework of Consumer Protection Law No. 6502 and special product warranty regulations. Service, on the other hand — whether within or outside the warranty period — covers maintenance, adjustments, training, error code analysis, and the paid resolution of use-related faults. Warranty claim management and service operations are carried out through the authorized dealer and service channel; our manufacturer technical service only handles products delivered to us, and requests are forwarded through the dealer channel.

Possible causes: motor gearbox/reducer coupling has broken, manual recovery lever is left in idle position, main spring is broken or loose, door leaf is jammed in the rail. Initial intervention: put the panel in safe mode, verify that the manual recovery lever has returned to the motor position, visually check the spring condition (visible breakage or loose winding) on the leaf and any freezing/obstruction in the rail. If the spring condition is suspect, do not try to open the door manually — an uncontrolled torsion spring release causes serious injury. If unresolved, open a technical support request with the label photo and fault observation details.

Reach our technical support team

Possible causes: limit switch drift, faulty photocell or safety edge trigger, loss of door weight balance (loss of spring tension), control board error code. Initial intervention: check whether there is dust or spider web on the photocell line and clean the lens, remove obstacles in front of the door, read the warning LED or error code on the control board and match it with the guide. Limit switch or spring balance settings should not be changed on-site — settings outside the model guide disturb safety and balance.

Reach our technical support team

Possible causes: loose or broken cable on one side, asymmetric wear of springs on both sides, loss of rail parallelism, roller or wheel jamming. Initial intervention: when the door is fully closed, visually compare the cables on both sides (fiber breakage, asymmetric tension), check for non-parallel sections in the rail. If cable slippage is present, the door should not be operated — there is a falling risk. Replacing the cable or spring on only one side disturbs mechanical balance; both sides are replaced together by authorized service.

Reach our technical support team

Possible causes: lack of lubrication (hinge, articulation, rail), wheel wear, looseness at panel hinges, motor reducer oil reduction, loose fastening bolts. Initial intervention: visually check that the roller path along the rail is lubricated, lubricate hinges and articulations with manufacturer-approved grease or silicone (as specified in the model specification), visually check the screws at panel hinges. Motor reducer oil level reduction and fastening torque values are matters for authorized service.

Typical signs: door is very heavy to lift manually (no balance), metallic "snap" sound while opening or closing, visible gap or distorted winding on the spring on the main shaft, oil drip marks. If any of these signs are present, the door should not be operated, access to the opening should be prevented, and authorized service should be contacted. Spring replacement is performed only by a trained technician with suitable safety equipment — an uncontrolled torsion spring release causes serious injury.

Reach our technical support team

Possible causes: cable coming off the pulley groove, cable getting stuck in the hinge and fraying, pulley corrosion, or bearing seizure. Initial intervention: with the door fully closed, visually inspect the pulley and cable line; if there is no acute jam, do not operate the door. If the cable has visibly frayed, raveled or come off the pulley, do not manually move the door either — there is a cable breakage risk. This is a situation that must be referred to authorized service.

Reach our technical support team

Possible causes: loosening of the side guide profile, breakage of the edge profile connection due to excessive pulling/slipping of the curtain, bottom bar imbalance, breakaway profile remaining in the wrong position. Initial intervention: manually lower the door (with a crank if available), visually check the guide profile and the curtain straps. If the dislodgement occurred due to forklift impact, the breakaway system may have engaged; in this case, the reset procedure in the model guide is applied. Permanent guide or profile replacement is a matter for authorized service.

Reach our technical support team

Possible causes: inverter (FU) speed trimpot has drifted, thermal protection engaged due to motor winding overheating, increased curtain mechanical friction, low supply voltage. Initial intervention: check the motor heating level by hand (if too hot, let it rest for 30 minutes), read the inverter LED and panel error code, verify with a multimeter that the supply is at nominal voltage level. Trimpot settings should not be changed by guessing on-site; going outside the reference value in the model guide will damage the motor.

Reach our technical support team

Possible causes: automatic close timer turned off, photocell line constantly detecting an obstacle, a constantly moving object (forklift, crane) in front of the door resetting the timer, mode selector on the control board in the "always open" position. Initial intervention: verify that the control board or door-side selector is in "automatic" mode, clean the photocell lens and visually check its line, ensure that the timer duration is within the value recommended in the guide (typical 5-30 s range). If the timer setting is to be changed, the steps in the user guide must be followed.

Errors on the FU inverter are indicated by LED flashing patterns or codes on the panel. The most frequently encountered errors: overcurrent (motor jamming, curtain weight), overvoltage (supply fluctuation), thermal protection (motor or inverter overheating), phase loss (break in the motor output cable). Initial intervention: cut power for 1 minute and reapply (reset); if the error persists, match the code-table from the guide, check motor cable connections and thermal fuses. In case of overcurrent or burnt component suspicion, the inverter must not be opened; authorized service must be engaged.

Reach our technical support team

Possible causes: ceiling radar or active infrared sensor sensitivity set too high, dirt or sticky film on the sensor cover, a fixed object (poster, hanging item) in front of the sensor, loose sensor cable connection. Initial intervention: clean the sensor cover with a microfiber cloth, check fixed objects below the sensor and in front of the door, visually inspect the cable terminals. Sensor sensitivity adjustment varies by model (via jumper or small button); the step sequence in the model guide must be followed.

Errors on the R2 control board are reported via flashing patterns of the LEDs on the top panel. Typical codes: motor encoder error, sensor connection, photocell line, fixed object detection. Initial intervention: read the LED code descriptions from the label next to the board, or refer to the code table in the model's user guide. Battery replacement and factory reset procedures are described in the guide. For situations requiring software or recovery, do not dismantle the board; call authorized service.

Reach our technical support team

Possible causes: seal wear (heat, ozone, abrasion), loss of parallelism between chassis and leaf, hidden screw loosening, wear of the seal brake on the top rail. Initial intervention: visually check the entire seal line (cuts, hardening, deformation), clean the seal channel, check whether there is uniform pressure between the chassis and the leaf. Seal replacement must be done with material in manufacturer-approved dimensions; equivalent commercial seals cannot guarantee hermetic performance (hygiene, temperature).

Possible causes: main fuse tripped, remote or manual button connection broken, motor thermal protection active (after heavy use), induction loop detector continuously detecting vehicle (blocking closure), motor coupling or belt breakage. Initial intervention: check the panel fuse, verify that the manual button is connected to the terminal on the board, if there is an induction loop, check for metal pieces (pallet, plate) along the lane. Belt breakage is a matter for authorized service; the use of the manual lock key for mechanical opening is described in the model's guide.

Reach our technical support team

Possible causes: water or moisture in the loop coil (cable insulation degraded), detector sensitivity incorrectly set for vehicle type, loop cable broken (road cut crack), detector supply voltage dropped. Initial intervention: observe the "detect" LED on the detector panel while passing a test vehicle, increase the sensitivity stage according to the guide. If loop damage is suspected, electrical resistance measurement and, if necessary, re-winding of the loop is done — this is a matter for authorized service.

Reach our technical support team

Possible causes: LED power cable broken or loose, LED bar fuse blown, controller malfunction, LED segment wear (long-term heavy use). Initial intervention: observe the LED bar segments during the barrier arm opening/closing cycle (whether the whole bar or a single segment is off), visually check the LED power terminal and fuse on the control board. Complete LED bar replacement must be done with the manufacturer-approved set; an equivalent LED strip may affect the control board due to voltage or frequency incompatibility.

Possible causes: weak remote battery, damaged or misplaced receiver antenna, new RF noise in the environment (nearby device, GSM repeater), drift of the remote frequency. Initial intervention: replace the battery (typical 12 V A23 or CR2032 — verify from the model label), check that the receiver antenna is straight and in a visible position. The remote code learning procedure is described in the model's guide; after a factory reset, all remotes must be re-taught.

Possible causes: mechanical stop position drift, end-stop limit switch trigger arm bent, control board took an incorrect record in learning mode, gear coupling slippage. Initial intervention: visually check that the mechanical stop is in place, check whether the limit switch arm is in the correct position, run the learning mode from the control board again (with the step in the guide). Instead of changing parameters by on-site observation, the first intervention is to repeat the motor learning process in the order in the guide.

Reach our technical support team

Possible causes: force (force/torque) trimpot setting at a high value, leaf weight has increased (panel or casting-like accessory added later), motor mechanical friction has decreased (adjustment needed after lubrication), momentum effect because the speed setting is high. Initial intervention: apply the force learning procedure in the model guide; if there is a change in leaf weight, motor capacity should be re-evaluated. The EN 12453 standard emphasizes that force adjustment is critical for personal safety; bring it to the minimum required value.

Reach our technical support team

Possible causes: battery capacity reduced (typical lifespan 3-5 years), solar panel efficiency decreased (dust, shade, tilt drift), charge regulator malfunction, cable connection oxidation. Initial intervention: measure the battery voltage with a multimeter under load/no load (for a 12 V system, min ~11.8 V when full), clean the solar panel surface, observe the regulator's charge LED during sunny hours. Real battery capacity measurement requires a capacitometer or service test; battery replacement must be of the same type and capacity.

Possible causes: lip hinge rusting or jamming, lip cylinder has air (hydraulic system), control panel lip-down command not working (relay or switch), hydraulic oil level reduced. Initial intervention: visually check the lip hinge, if there is jamming, lubricate with manufacturer-approved oil, test the terminal of the lip-down button on the control panel and the trigger of the hydraulic valve. If the hydraulic oil level is low, the unit should be visually kept clean and level addition should be done by authorized service.

Reach our technical support team

Possible causes: cylinder rod seal wear, looseness at the hose connection nut, valve selector stuck in flat position, deterioration of the seal on the hydraulic tank plug. Initial intervention: clearly identify the source of the leak (by tracing the floor mark), check the connection nuts with a wrench (do not over-tighten by force — there is a torque limit). Cylinder seal replacement is a matter for authorized service; uncontrolled operation disturbs cylinder performance and loading safety.

Reach our technical support team

Possible causes: internal hydraulic system leak (check valve or cylinder), platform fastening bolts loose, slippage of side anchors inside the pit. Initial intervention: mark the platform position when the leveler is empty and the control panel is off, and check again after 24 hours (static test). If there is a position loss, check valve system testing must be done by authorized service. If fastening bolts visibly appear loose in inspection, they must be tightened to torque value.

I380 phase protection cuts the circuit and protects the motor in case of a current or phase sequence issue. Causes of tripping: phase loss in the three-phase supply, reverse phase sequence wiring, short circuit in motor windings, faulty measurement transformer. Initial intervention: sequentially measure the three phases on the panel with a multimeter (~220 V between each phase and neutral, ~380 V between phases), verify the phase sequence with a phase sequence tester. If a short circuit in the motor winding is suspected, the board trigger should not be cleaned without removing the motor; a burnt winding will cause repeat tripping.

Reach our technical support team

FU trimpots (speed, brake, ramp) may have drifted due to mechanical vibration during operation; this causes speed inconsistency or opening/closing imbalance. Initial intervention: refer to the reference trimpot values in the model guide, restore the setting by experimenting in small steps (1/8 turn) with a small screwdriver. The DIP switch arrangement defines the door type (HPVC, cold storage, etc.); the wrong combination changes the motor characteristics. For a comprehensive reset, authorized service should be contacted.

GIGA SEDO premium industrial control keeps readable error messages on the LCD display (e.g., "PHASE LOSS", "ENCODER FAIL", "CONTACTOR FAIL"). If the LCD is completely off, this is a supply or LCD backlight issue. Initial intervention: photograph the error message for record, match it from the message-meaning table in the guide, read the event history (history menu) on the board. If an RS485 connection is present, support can be obtained via remote reading. In case of burn or component suspicion, no manipulation should be performed on the board.

Reach our technical support team

Possible causes: short circuit at the accessory (photocell, flasher, lock) terminal, grounding jam at the motor output terminal, connecting too many parallel accessories (exceeding the board's current limit), insulation leakage from a humid environment. Initial intervention: remove all accessory connections one by one and replace the fuse for testing — whichever accessory causes the fuse to blow again is faulty or its connection is faulty. In case of short circuit suspicion at the motor output, motor cable insulation should be measured; in case of burnt winding suspicion, the motor should be removed and tested.

Reach our technical support team

Likely cause: the motor power (current) trimpot is set too low, so the motor cannot fully drive the door. First step: increase the motor power trimpot on the board (T1 on the GATE 24 board) in small steps until the door moves fully; the increase direction is given in the board/model guide (on the GATE 24 board, for example, the trimpot decreases clockwise and increases counter-clockwise). If travel still fails with the current trimpot at maximum, there may be mechanical binding or a motor/leaf mismatch. Trimpot adjustment must only be carried out by trained personnel, within the range in the model guide.

Reach our technical support team

Cause: the motor rotation direction is wired in reverse. First step: cut the power; on DIP-switch boards such as GATE 24, change the direction DIP switch (typically no. 4); on sliding/three-phase boards, swap any two of the motor supply leads to correct the direction. Always cut the power before working; after the direction change, re-confirm the limit/encoder learning at the closed and open ends.

Reach our technical support team

Cause: the microprocessor may have gone into self-protection after a momentary voltage/current fluctuation. First step: cut the power, wait until all LEDs on the board go off completely, then re-apply power (reset). If the processor LED still does not light and the board does not respond to commands, the microprocessor has failed; the board must be assessed or replaced by authorized service. Do not intervene on the board in this case.

Reach our technical support team

A common wiring mistake: connecting the earth line to the terminal instead of the supply neutral. The board is then powered and the green LED lights, but the system will not run. Solution: verify that NEUTRAL — not earth — is used at the supply input. On three-phase (380 V) boards, also check phase order and phase integrity. Electrical connections must only be made by an authorized person with the power disconnected.

Reach our technical support team

Motor movement depends on the safety (stop) circuit being closed. First step: confirm that the stop/safety LED on the board is lit. If it is off, an element in the safety chain is holding the circuit open: a stuck safety/limit switch, the motor left in manual (crank) position, a crank shaft left engaged, or the motor thermal protection tripped. Check these points one by one and close the safety circuit. If thermal protection has tripped, wait for the motor to cool.

Reach our technical support team

The symptom indicates that power is not fully reaching the motor: a loose or detached supply lead at the motor output terminal, or a lost phase on a three-phase supply. First step: cut the power and check that the connections at the motor output terminal are tight. If the cables are in place, measure the voltage across the motor output leads; on a three-phase (380 V) board the nominal voltage (380 V) should be present between each pair of phases. If a phase or voltage is missing, review the supply and terminal connection with an authorized person.

The R2 unit's display codes point to the source of the fault: o1 jammed while opening, o2 jammed while closing, o3 overcurrent protection, o4 button fault, o5 radar fault (a common cause is the radar sensitivity set too high, giving a constant command), o6 mechanical jam, o7 battery voltage low, o8 photocell fault (the sensors do not see each other or a cable is damaged; the source is found with the photocell test buttons on the unit), o9 mains voltage low, 10 encoder fault (encoder/cable fault or mechanical binding during reset), St service time. After power-up, 1-2-3 shown in sequence on the display is the normal limit learning; if the door does not work and 1-2-3 persists, check the mechanical installation (the leaf not seated on the guide, or the tension wheel pressure). Transient jam codes such as o2 need no action as the door keeps working; the displayed code is cleared by holding the P2 (ESCAPE) button on the unit for 3 seconds. Parameter changes must only be made by trained personnel.

Reach our technical support team

Cause: the closing-direction push-force parameter (C4 on the R2 unit) may be set too high, so the door treats the limit point as an obstruction and repeats the learning. First step: lower the C4 push-force parameter by a few units (typically 5 units), then cut and re-apply power; the door will re-learn its limits. Parameter values must only be changed by trained personnel, within the range in the model guide.

Reach our technical support team

The most common cause is a slack drive chain. First step: adjust the chain tension nut on the rail (the M8 nut on PULL 1000) per the manufacturer's instructions, so the chain is lightly tensioned without being over-tightened. Noise can also come from loosened mechanical fixing screws; check the rail and bracket fixing points. After adjustment, fully open and close the door a few times to confirm the noise is gone.

Reach our technical support team

If the button works but the remote does not, the problem is on the remote side, not the motor or board. Two likely causes: the door may be in lock/block mode (turn off lock mode); or the remote is not paired to the unit or its battery is flat (re-pair the remote following the steps in the model guide, and replace the battery if needed). A shortened remote range also points first to the battery. After pairing, confirm the remote works within range.

The GATE 24 / G-24 board is multi-purpose and runs according to the connected motor type: it has circular (swing), barrier, sliding and sectional modes. The motor type is selected with the BT2 button, and the selected type is shown by how the motor-type LED (Led 5) lights: steady in circular mode, off in barrier mode, at steady intervals in sliding mode, and flashing at fast intervals in sectional mode. If a type unsuitable for the door is selected, the movement, speed or limit behaviour will be wrong; after selecting the correct mode the limits must be re-learned. This setting is made only by trained personnel, per the model guide.

r-tec RF-433 receivers work in standard mode with a single firm/remote code; in this mode only remotes with the same code (copies) can be paired, and a remote with a different code is not accepted. To use remotes with different codes on one receiver, the receiver is put into 'common receiver' mode (with the relevant DIP switch on the receiver; the DIP number differs between the socket and cabled receiver). In common-receiver mode only the same button of each different remote is paired once. Switching between modes erases the remotes paired in the previous mode; also, once a receiver has been first programmed by one firm, a remote from another firm cannot be paired afterwards even if it is the same type. Follow the steps in the model guide.

The factory password is 1234, and a password of 4 to 8 digits can be set. To change it: hold Enter for 10 seconds (release when the red and green LEDs are steady together), enter the old password and press Enter (if correct the LEDs blink once), enter the new password and press Enter, then enter the new password again and press Enter — when the LEDs flash 5 times the password is saved. If the LEDs go off despite entering the new password, you may have entered it incorrectly at the last step; repeat the procedure from the start. In use, a correct password + Enter lights the green LED and opens the door, while a wrong password lights the red LED.

The FLA230-24 LED flasher accepts both 24 V AC/DC and 220 V AC; one of the two is chosen according to the site supply (the board has separate 24 V and 220 V terminals). IMPORTANT: do not connect both 24 V AC/DC and 220 V AC to the board at the same time — only one supply type must be used, otherwise the board is damaged. The flasher is connected to the control board's flasher output and typically lights as a warning throughout the door's opening/closing movement.

Reach our technical support team

The safety photocell consists of two facing parts, a transmitter (TX) and a receiver (RX), mounted on either side of the passage and aligned to see each other (typical range 25 m). The transmitter only takes power (+/−); the receiver has power (+/−) and a relay output (COM/NC/NO) that is connected to the photocell input of the control board. The supply is 12/24 V AC/DC. When an object breaks the beam, the receiver's relay changes state and the door stops closing and re-opens. If the photocells do not see each other, first check the alignment and the cable connections; on r-tec automatic-door units the line can be verified with the photocell test button.
