Actuator use
Automatic calibration
(DIP N. 7 OFF)
The actuator
pushes/pulls 2 times
(unexpected stall) trying
to remove the possible
obstacle. After 2 tries an
Calibration/
alarm is signalled and
first installation
the actuator moves to
initial position and does
not respond to control
signal. Stroke value is
not updated because
out of range
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
Calibration/
new stroke limit, then it
first installation
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 (wrong range)
The actuator tries 5
times against the new
normal
stall condition and then

after 10s the actuator
updates the new stroke

The actuator moves
toward the new stall

Actuator behaviour
Manual calibration
(DIP N. 7 ON)
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 control signal. The
actuator keeps the
previous stroke
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 (wrong range)
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 new stroke
length, but after 60s
makes other attempts
to verify the stall
condition
The actuator moves
toward the new stall
condition with a lower
speed; after 10s the
actuator does not
update the new stroke
value
The actuator is
still working but
