12. Setup
12.1. Teach-in function for actuator (only for unicode evaluation)
The actuator must be allocated to the safety switch using a teach-in operation before the system forms a functional unit.
During a teach-in operation, the safety outputs and the door position signal OD are switched off, i.e. the system is in the
safe state.
Tip!
It is recommended to perform the teach-in operation prior to mounting. Mark switches and actuators
that belong together in order to prevent confusion. For devices to be connected in series, we recom-
mend performing the teach-in operation separately for each device prior to series connection.
Important!
Ì
The teach-in operation may be performed only if the device functions flawlessly. The red DIA LED
must not be illuminated.
Ì
The safety switch disables the code of the preceding device if teach-in is carried out for a new
actuator. 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.
Ì
The safety switch can be operated only with the last actuator taught-in.
Ì
The number of teach-in operations is unlimited.
Ì
If the switch detects the actuator that was most recently taught-in when in the teach-in standby
state, this state is ended immediately and the switch changes to normal operation.
Ì
If the actuator to be taught-in is within the actuating range for less than 30 s, it will not be activat-
ed and the most recently taught-in actuator will remain saved.
12.1.1. Preparing device for the teach-in operation and teaching-in actuator
1. Apply operating voltage to the safety switch.
¨
The green STATE LED flashes quickly (5 Hz).
A self-test is performed during this time (approx. 5 s). After this, the green STATE LED flashes cyclically three times
and signals that it is in standby state for teach-in.
Standby state for teach-in remains active for approx. 3 minutes. On switches that have not been taught in, teach-in
standby is unlimited.
2. Move new actuator to the switch (observe distance < S
ao
).
¨
Teach-in operation starts, green STATE LED flashes slowly. During the teach-in operation, the safety switch checks whether
the actuator is a disabled actuator. After successful teach-in, the green STATE LED and red DIA LED flash alternately. The
new code has now been stored, and the old code is disabled. The teach-in operation takes approx. 30 s.
3. Disconnect safety switch from the operating voltage for 3 seconds.
¨
The switch is in normal operation after the self-test.
