Setup
LED indicators
STATE LED green Normal operation
Flashing Teach-in operation (for further signal function
see status table)
OUT LED yellow Valid actuator detected
ERROR LED red - Test input activated
- Internal electronics fault
- Invalid teach-in operation
(see status table)
Reset
In case of operating faults, the evaluation unit can be reset to the operating state
by interrupting the power supply for approx. 10 seconds.
Teach-in function for actuator
The actuator must be assigned to the evaluation unit using a teach-in function
before the system forms a functional unit. During a learning process, the safety
outputs are open and the door monitoring output is at LOW, i.e. the system is in
a safe condition.
Important!
Ì
Repeated teach-in of the same actuator on the same evaluation unit is not
possible.
Ì
The number of teach-in operations on one evaluation unit is limited to a maxi-
mum of 8
Ì
The evaluation unit can only be operated with the last actuator taught
Ì
A teach-in operation is invalid if:
Ì
the teach-in operation is cancelled before the green flashing LED goes out
Ì
the power supply is switched off during the teach-in operation
Ì
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)
Ì
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.
