Before commissioning
Adjusting motor As soon as the FMS is supplied with voltage, it attempts to drive the actuator
limit switch motors to the lower boundary of the factory curve. If the end-bearing's
limit switches are not properly adjusted for this then the motor may hit
the actuator's mechanical stop.

This can damage the motor or the valve.

Therefore:
Check the position of the end-bearing limit switches in the motors, taking
into account the motor output shaft's travel.
If in doubt, set a shorter travel. It can be readjusted later.
