12.2. Teach-in function for 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 is fully automatic. 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 simplies above all teach-in with large installations.
Important!
Ì 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
taught-in the rst actuator. Once taught-in, switches remain in the teach-in standby state for ap-
prox. 3min. after each switch-on.
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 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 The actuator to be taught-in is not activated if it is within the actuating range for less than 30s.
