Lift levelling with magnetic sensors
A
The module monitors the two re-levelling sensors and when the
cabin is in the re-levelling zone, it enables the safety outputs.
One safety output must be connected to bypass the circuit
that monitors the cabin landing and cabin doors, when the lift
cabin is inside the re-levelling zone; further to the landing and
re-levelling of the cabin at the oor, the safety module detects
eventual faults and the lift controller will stop the lift.

The inputs S12, S22 are connected to the re-levelling zone
sensors
