Teach-in function for actuator
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 bit sequence 0000 is transmitted, i.e. the system
is in the safe state.
Important:
Ì The safety switch disables the code of the previous actuator if teach-in is car-
ried out for a new actuator. Teach-in is not possible again immediately for this
actuator 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.
Ì The safety switch can only be operated with the last actuator taught.
Ì If the switch detects the actuator that was most recently taught when in teach-
in standby state, this state is ended immediately and the switch changes to
normal state.
Ì The actuator being taught is not activated if it is within the operating distance
for less than 60 s.
