6.2.2 Teaching-in and locking the TR4 Unique Coded
How to teach-in an actuator and lock the TR4 Unique Coded for
further teach-in processes:
= Switch on the voltage supply of the sensor.
= Move the actuator inside the response range of the TR4 Unique
Coded. The sensor then automatically starts the teach-in process.
= Remove the actuator from the response range during step 4 of the
teach-in sequence (“programming complete”) until the Status/Diag
LED illuminates Ν Red.
= Move the actuator back inside the response range. The Status/Diag
LED flashes ∏ Green again (1 Hz). The sensor is now locked and no
further teach-in processes are possible. However the Status/Diag
LED still indicates the number of teach-in processes that would have
been possible with its flashing signal for 15 seconds.
Teach-in sequence
1. Actuator inside the response range: The Status/Diag LED flashes
∏ Green (1 Hz).
2. Verifying the actuator: The Status/Diag LED flashes for 15 seconds
∏ Green/red (1 Hz).
3. Programming the sensor: The Status/Diag LED flashes for 15 sec-
onds ∏ Green/red (4 Hz).
4. Programming complete: The Status/Diag LED flashes ∏ Green
(1 Hz) and indicates during this process the remaining number of
possible teach-in processes followed by a pause. This signal is re-
peated for 15 seconds. If, during these 15 seconds, you remove
the actuator from the response range and return it to the response
range, then the sensor is locked for further teach-in processes.
5. Teach-in complete, sensor ready: The Status/Diag LED is illumina-
ted Ν Green.
• The locking process (removal and return of the actuator) must be
completed within the 15 seconds of step 4.
• The lock cannot be removed again.
