Information on unicode sensors
–
The learning process can be repeated as often as required.
–
The sensor only detects the last actuator taught in.
–
If a new actuator (B) is taught in, the sensor blocks the code of the last actuator (A). This
actuator (A)
cannot
be used during the next learning process.
–
The sensor releases the blocked code again after a third actuator (C) has been taught
in. Actuator (A) can be used again. Actuator (B) is now blocked.
–
If the actuator to be learned is located in the response area of the sensor for
less than
30 s
, the sensor will not accept it. The actuator learned last remains valid.
5.3.1
Teaching in actuators
Proceed as follows to teach in an actuator:
Starting situation:
the actuator is not within the response area / the safety equipment is
open.
1.
Apply the operating voltage to the safety switch.
The green STATE LED flashes quickly, 5 Hz.
The sensor is performing a self-test for 5 s, approximately.
The green STATE LED flashes cyclically: 2 x green, off long.
The sensor is ready to learn:
3 min when teaching in again, unlimited for switches that have not been taught in before.
2.
Move the actuator towards the sensor.
Observe the assured operation distance S
ao
.
The green STATE LED flashes cyclically: off short, green long.
The learning process has started.
3.
Keep the actuator within the response are of the sensor for 30 s, approximately.
The red DIAG LED and the green STATE LED flash alternately: red short, green long.
The learning process has been completed successfully.
4.
Restart the safety switch:
a)
Disconnect the operating voltage.
b)
Apply the operating voltage again.
The safety switch is in normal mode after the self-test has been carried out successfully.
Observe the LED status indicators on the sensor.
See Section “LED status indicators and switching states” on page 43.
If the learning process has not been successful, the LEDs flash in the reverse order: red
long, green short. A blocked actuator could be involved in the case of unicode sensors.
