r-tec Automatic Sliding Door

Overview

The r-tec automatic sliding door is an automatic pedestrian access solution offered with an aluminium profile + glass panel combination, in double-leaf 120 + 120 kg or single-leaf 150 kg carrying capacity. The standard chassis supports single-leaf and double-leaf variants; the telescopic chassis provides a wider net transit opening with 4 leaves using the same motor (the leaves hide behind each other). The R2 control unit is used in all applications — dual-supply 230 VAC / 24 VDC, 100 W power, IP23 protection.

Speed and performance

Door type	Opening speed	Closing speed	Total cycle
Single-leaf (150 kg)	90 cm/s	63 cm/s (70%)	~3 s (1 m opening)
Double-leaf (120 + 120 kg)	180 cm/s	126 cm/s (70%)	~2 s (1 m opening)
Telescopic (4 × 60 kg)	180 cm/s	126 cm/s	~2 s

The opening speed of 90 cm/s for single-leaf is at the top of its class; with parallel movement on double-leaf, 1 metre opening in under 2 seconds is provided. The 70% closing-speed ratio is intended to reduce trapping risk through slower closing.

R2 control unit — 23 parameters

The R2 board enables fine tuning to the site with 23 separate parameters. Parameter groups:

• Opening settings (o1-o4) — Opening acceleration distance, opening speed, deceleration distance and push force.
• Closing settings (C1-C5) — Closing acceleration distance, closing speed, deceleration distance, push force and motor pressure after closing.
• Partial opening (o5) — Opening rate when partial mode is active (25% / 50% / 75%).
• Airlock (o6) — Synchronous operation between two consecutive doors.
• Hold-open time (t1) — 0–60 s; separate scenarios for busy hours and quiet hours.
• Electric lock (L1, L2) — Lock operation type and door movement delay after the lock engages.
• Photocell settings (F1, F2, Ft) — Photocell 1/2 active state and external/internal photocell selection.
• Battery and motor direction (b1, r1) — Behaviour on power loss and motor rotation direction.
• Remote control and service (Rf, S1, P1) — Remote mode, service interval and panic exit.

12 fault codes — fast fault detection

Code	Meaning
o1	Trapped while opening
o2	Trapped while closing
o3	Overcurrent protection
o4	Button fault
o5	Radar fault
o6	Mechanical jam
o7	Battery voltage low
o8	Photocell fault
o9	Mains voltage low
10	Encoder error
11	Overcurrent (>5 s) protection
St	Service time

When the service team goes to the site, with the code on the R2 screen they reach the root cause directly — the traditional fuse-check-replace cycle is eliminated.

5 operation modes

Selector switch transitions:

1. Hold open — Door continuously open. For keeping the entrance fully open at night or for evacuation scenarios.
2. Partial opening — Opening 40-60% (set with parameter P1). Limits air circulation in air-conditioned/heated indoor environments.
3. One-way — Activates only the inward or outward safety strip. Used at one-way exit entrances (cinema exit, stadium exit).
4. Automatic (standard) — Normal operation triggered by photocell/PIR sensor. Typical daytime operation.
5. Hold closed — Door continuously closed, after-hours lock mode.

Archived document records and evidence boundary

• TÜV Austria record 16-PS-0009-TAT-21-MAD-2479 identifies the product as AUTOMATIC DOOR and the type/model scope as r-tec, open, con-tech. Renewed on 12 February 2021, it expired on 12 February 2022; it does not separately name the sliding door, R2 control or the leaf configurations on this page.
• SATSO / TOBB Domestic Product record 20221188100201 states a 100% rate only for AUTOMATIC DOOR and a validity period of 8 September 2022–8 September 2023. It gives no component-level scope for the motor, control or mechanical assembly.

Both are expired archive records. The model, control, equipment and current conformity file for the proposed sliding door are verified separately.

Field discipline

• Rail alignment — In the standard chassis, the rail parallelism must be adjusted to millimetric precision; deviation causes motor thermal protection to trip.
• Sensor positions — PIR + photocell combination; PIR detects long-range approach, the photocell protects against trapping at the door threshold. Both must be active at the same time.
• Safety area — A 50 cm buffer is mandatory in the opening and closing direction; a wall/column/décor element placed in this area creates a trapping risk.
• Glass panel thickness — In indoor applications open to traffic, tempered glass (at least 8 mm) is recommended; safety against falls.
• Periodic maintenance — Recommended every 6 months for heavy use (airport, shopping centre) and every 12 months for standard office-store applications; maintenance is carried out by the authorised technical team.

Model notes

Motor power and gear selection are calculated according to door mass and rail friction; a detailed sizing table is in the technical PDF. Firmware update via a boot stick is possible on the R2 board — when new safety standards are released, the update is applied by an authorized technician via a boot stick.
