Teaching
Individually coded safety door switches and actuators will require the following teach-in procedure:
1. Keep the actuator away from the detection range and switch the safety door switch's voltage supply off and back on.
2. Introduce the actuator in the detection range. The teach-in procedure is signalled at the safety door switch, red LED on, yellow LED flashes (1
Hz).
3. After 10 seconds, the yellow LED gives brief cyclic flashes (3 Hz). Switch off the supply voltage of the safety door switch. (If the voltage is not
switched off within 5 minutes, the safety door switch cancels the teach-in procedure and signals a false actuator by 5 red flashes).
4. Switch the supply voltage back on. The actuator must be detected once more in order to activate the taught actuator code. In this way, the
activated code is definitively saved.
For ordering suffix D41D-1, the executed allocation of safety door switch and actuator is irreversible.
When the above procedure is attempted with a D41D-1 which already completed teaching, the teaching procedure will not start.
For ordering suffix D41D-2, the teach-in procedure for a new actuator can be repeated an unlimited number of times. When a new actuator is
taught, the code, which was applicable until that moment, becomes invalid. Subsequent to that, the safety outputs will be disabled for ten minutes,
thus providing for an increased protection against intentional tampering.
The green LED will flash until the expiration of the time (10 minutes) of the enabling inhibit and the detection of the new actuator.
In case of power failure during the lapse of time, the 10-minutes tampering protection time will restart.
When the above procedure is attempted with a combination of D41D-2 and actuator which already completed teaching, the teaching procedure
will not start.
