The actuator pushes/pulls
5 times (unexpected stall)
trying to remove the possible
obstacle. After 5 tries an alarm
is signalled (RED LED ON)
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. Alarm is signalled
(RED LED ON) and the
actuator moves to the initial

The actuator exits the 60 mm
stroke range and it moves
toward the new stroke limit
signalling an anomaly (RED

not calibrate the stroke
The actuator pushes/pulls 2

The actuator tries 5 times
against the new stall condition
and then after 10s the actuator
updates the new stroke length;
During these 10s RED LED
is ON
The actuator tries 5 times
against the new stall condition.
At the end of the attempts the
fault will be signalled (RED
LED ON). The actuator does
not update the new stroke
length, but after 60s makes
other attempts to verify the
stall condition
