Behaviour following a power failure
After the power returns, the slide carriage must be re-coupled
to the carriage coupling.
1 .
Move the carriage coupling close to the slide carriage.
2 .
Push up the green coupling slider.
3 .
Move the door by hand until the slide carriage snaps into
the carriage coupling.
4 .
Push the hand transmitter button or a button with
impulse command.
If the power failure occurred during door travel, the operator
carries out a reference run with the first impulse command.
5 .
Check whether the door completely reaches its OPEN

multiple uninterrupted door runs.
If the behaviour does not correspond to that described in step
5, even after multiple uninterrupted door runs, new learning
runs are necessary. Delete the previous door data
(see section 11.2 and 5.1).
