11.2. Teach-in function for actuator (only for unicode evaluation)
The actuator must be assigned to the evaluation unit using a teach-in function before the system forms a functional unit.
During the teach-in operation the safety outputs are open and the door monitoring output is LOW. The system is in the safe
state.
Important!
Ì
During the teach-in operation the following conditions must be met:
-No state change, e.g. opening of a safety door.
-The power supply must not be switched off.
Ì
If these conditions are not met, the evaluation unit switches to the safe fault state (ERROR LED
illuminates) and signals this operating fault with the STATE LED.
Ì
The number of teach-in operations on one evaluation unit is limited to a maximum of 8.
Ì
The evaluation unit can be operated only with the last actuator taught-in.
Ì
An actuator that has not been subjected to teach-in will not be detected by the related read head.
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 sys-
tem automatically switches to the teach-in mode. In both cases, a teach-in operation with a dura-
tion of 60 seconds is started; however, the last actuator code remains active (see system status
table) – a new code is not taught-in.
11.2.1. Carrying out teach-in for first actuator (default setting on delivery)
To trigger the first teach-in operation, the user must perform the following actions in the stipulated order:
1. Start teach-in operation
-Switch on operating voltage (STATE LED flashes at approx. 4 Hz)
-Close door to be monitored (the actuator must be in the actuating range of the read head)
-Teach-in operation starts (STATE LED flashes at approx. 1 Hz)
-Wait for acknowledgment of the teach-in operation (STATE LED goes out after approx. 60 seconds)
2. End teach-in operation
-Interrupt operating voltage for at least 3 seconds (code for the actuator taught-in is activated)
3. Check safeguard for effectiveness
