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

At the end of the attempts
the fault will be signalled. The
