installation
The actuator pushes/pulls 2 times
(unexpected stall) trying to remove
the possible obstacle. After 2
tries an alarm is signalled and the
actuator moves to initial position
and does not respond to control
signal. Stroke value is not updated
because out of range
The actuator pushes/pulls 2
times against endpoint during
calibration and the actuator
moves to the initial position and
then it does not respond to the

installation
The actuator exits the 60mm stroke
range and it moves toward the new
stroke limit signalling an anomaly.
The actuator pushes/pulls 2 times
against the new stroke limit, then it
goes back to the initial position still
signalling the anomaly until it is not
within 60mm. The actuator does
not calibrate the stroke after 10s

The actuator tries 5 times
against the new stall condition.
At the end of the attempts
the fault will be signalled. The
actuator does not update the
