b. Motorised operation
(BM driving mechanism)
Activate the corresponding operation order.
If, for any reason, the motor stops halfway through a
motorised operation, before restarting it you must
finish the operation manually, so that the whole
mechanism: sensors, controllers, etc., are in a reliable,
effective and logical position for the control system of
the motorisation when they connect with it again.
3.
Verify that the cubicle is in connected position.
