Teaching-in actuator (only for unicode evaluation)
The actuator must be allocated to the safety switch using a teach-in function before the system forms a functional unit.
During a teach-in operation, the safety outputs are switched off, i.e. the system is in the safe state.
The teach-in operation starts automatically. The number of possible teach-in operations is unlimited.
Tip!
Prior to switching on, close the guard on which the actuator to be taught-in is installed. The teach-in
operation starts immediately after switching on. This feature simplifies above all teach-in with series
connections and on large installations.
Important!
The teach-in operation can be performed only if the device does not have any internal fault.
Ì
Devices in the condition as supplied remain in teach-in standby state until they have successfully
Ì
taught-in the first actuator. Once taught-in, switches remain in the teach-in standby state for approx.
3 min. after each switch-on.
The safety switch disables the code of the preceding device if teach-in is carried out for a new actuator.
Ì
Teach-in is not possible again immediately for this device if a new teach-in operation is carried out.
The disabled code is released again in the safety switch only after a third code has been taught-in.
The safety switch can be operated only with the last actuator taught-in.
Ì
If the switch detects the actuator that was most recently taught-in when in the teach-in standby state,
Ì
this state is ended immediately and the switch changes to normal operation.
The actuator to be taught-in is not activated if it is within the actuating range for less than 30 s.
Ì
1. Establish teach-in standby:
- Devices in the condition as supplied: unlimited teach-in standby after switching on.
- Switch already taught-in: teach-in standby is available for approx. 3 min after switching on.
Teach-in standby indication, STATE LED flashes 3x repeatedly.
¨
2. Insert the actuator during teach-in standby.
The automatic teach-in operation starts (duration approx. 30 s).
¨
During the teach-in operation the STATE LED flashes (approx. 1 Hz).
Alternate flashing of the STATE and DIA LEDs acknowledges the successful teach-in operation.
Teach-in errors are indicated by the illumination of the red DIA LED and a flashing code on the green STATE LED (see
chapter 15. System status table CTP/CTA-L1/2-BR on page 38).
3. Switch off operating voltage (min. 3 s).
The code of the actuator that was just taught-in is activated in the safety switch.
¨
4. Switch on operating voltage.
