Teach-in function for actuator
The safety actuator must be allocated to the evaluation unit using a teach-in func-
tion before the system forms a functional unit. During a teach-in operation, the
safety outputs and the door monitoring output OUT are LOW, i.e. the system is in
the safe state.
Important!
Repeated teach-in of the same actuator on the same evaluation unit is not
possible.
The number of teach-in operations on one evaluation unit is limited to a maxi-
mum of 8
The evaluation unit can only be operated with the last actuator taught.
A teach-in operation is invalid if:
the teach-in operation is cancelled before the green flashing LED goes out
the power supply is switched off during the teach-in operation.
When the evaluation unit is switched on (operating voltage is applied), the
STATE LED signals the number of possible remaining teach-in operations
(see system status table).
After the eighth teach-in operation or if an "old" actuator is placed against the
read head, the system automatically switches to the teach-in mode. In both
cases, a teach-in operation with a duration of 60 seconds is started; how-
ever, the last actuator code remains active (see system status table) in the
memory – a new code is not taught. 

Teach-in function for first actuator
(state on delivery)
Apply the operating voltage to the evaluation unit
green LED flashes fast (approx. 4 Hz)
Move actuator to the read head (observe distance < S
ao
)
teach-in operation starts, green LED flashes slowly (approx. 1 Hz)
Teach-in operation completed (after 60 seconds)
green LED goes out
To activate the actuator code from the teach-in operation in the evaluation unit,
the operating voltage must then be switched off at the evaluation unit for min.
10 seconds.
Check function of the safety guard (see section Functional check).
Teach-in function for a new actuator
Apply the operating voltage to the evaluation unit
Move new actuator to the read head (observe distance < S
ao
)
teach-in operation starts, green LED flashes (approx. 1 Hz)
Teach-in operation completed (after 60 seconds)
green LED goes out, new code saved, old code deactivated
To activate the new actuator code from the teach-in operation in the evaluation
unit, the operating voltage must then be switched off for min. 10 seconds.
Check function of the safety guard (see section Functional check).
