■
Fault when activating or deactivating lock.
Align actuator correctly and perform reset
by interrupting the voltage supply.
■
General fault. Perform reset by interrupting
the voltage supply. If the reset does not
rectify the fault, replace the device.
■
Actuator was moved outside sensing range
during locked state. Check the alignment of
the door.
■
Interference from similar device nearby
(≤200mm). Increase the distance and
reset the device.
■
Actuator damaged. Replace the actuator.
