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 meets the slow-closing requirement mandated by the EN 60335-2-103 safety standard — the risk of trapping is significantly reduced.

R2 control unit — 23 parameters

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

• Opening/closing deceleration distance (L1, L2) — End-of-travel softening, extends panel life.
• Hold-open time (t1) — 1–60 s; separate scenarios for busy hours and quiet hours.
• Operating speed (Rf) — Full opening speed ratio.
• Closing-speed ratio (Ft) — Adjustment over the standard 70% according to site.
• Opening ramp (St) — Slow start ramp.
• Partial opening percentage (P1) — Opening rate when partial mode is active.
• Brake force (b1) — End-of-closing brake force.
• Trap sensitivity (F1, F2) — Opening + closing direction separate.
• Selector mode (C1-C5) — 5 operation mode selection parameters.
• And others (o1-o7 = output channels, r1 = relay, Sx = sensor input sensitivities).

12 fault codes — fast fault detection

Code	Meaning
o1	Motor thermal protection
o2	Opening limit switch
o3	Closing limit switch
o4	Encoder error
o5	Photocell (opening)
o6	Photocell (closing)
o7	Overcurrent protection
o8	Low voltage
o9	Selector position error
10	Memory / EEPROM error
11	Mechanical block
St	System reset

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.

Certification and conformity

• TÜV AUSTRIA CE 16-PS-0009-TAT-21-MAD-2479 — 2006/42/EC Machinery Safety + 2014/35/EU LVD + 2014/30/EU EMC; EN ISO 12100, EN 60335-2-103, EN 61000-6-1/6-3.
• Domestic Product 20221188100201 — 100% domestic contribution (T.C. SATSO), fully domestic production including motor + control + mechanical components. Qualifies for domestic-product priority in public tenders.

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 — Every 6 months for heavy use (airport, shopping centre), every 12 months for standard office-store maintenance contract.

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.
