Technical specifications
1r-tec R2 Automatic Door Control Board
R2 is the standard control board of the r-tec automatic door series (sliding, single-leaf, telescopic, revolving). It can be ordered as a standalone spare part; it is the product preferred by dealers in the need to replace existing automatic door control boards.
Sustainability note
The selector + photocell + card reader input combination of the R2 board supports the door’s variable operating profile according to traffic — fully open during peak hours, automatic transition to night mode during off-hours providing energy savings.
Technical specifications
- Supply: 230 V
- Motor driver: 100 W DC automatic door motor
- Selector: 5-mode (full open / half open / one-way / night / manual)
- Input channels: photocell + radar + card reader
- Hold-open time: 1–60 s (programmable)
- Emergency: emergency-open contact + battery / UPS backup
Modes and programming
The five-mode selector sets the door’s operating profile by time of day and traffic: full open during peak hours, half open to limit heat loss, one-way allowing only entry or exit, night restricted to card or key after hours, and manual for servicing. Opening speed, closing speed and hold-open time are programmed separately on the board; when the safety photocell detects an obstacle while closing, the leaf re-opens automatically.

Installation and Commissioning
The R2 automatic-door control unit is commissioned after installation by learning the limits and selecting the operating mode. General flow:
- Limit learning: 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, the mechanical installation (the leaf seating in the guide, the tension-wheel pressure) is checked.
- Operating mode: The door behaviour (automatic, hold-open, winter mode, etc.) is selected with the mode selector.
- Parameters and fault codes: The display codes (o1-o9, 10, St) point to the source of a fault; parameters such as push force (for example C4 in the closing direction) are set within the range in the model guide. A transient code is cleared by holding the P2 (ESCAPE) button on the unit for 3 seconds.
- Safety: The photocells are connected and verified with the test buttons.
Parameter changes must be made only by trained personnel.
Frequently Asked Questions
Below we've compiled the most common questions and answers regarding this product.
Error LED is on at the r-tec R2 control board
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.
I see a fault warning code on the R2 automatic (pedestrian) door unit display (o1-o9, 10, St)
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.
The automatic (pedestrian) door does not stop at the closing end and keeps restarting limit learning
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.
