WHEN ACTUATOR BEHAVIOUR
Automatic Calibration SW7
OFF
The actuator pushes/
pulls 5 times (unexpected
stall) trying to remove the
possible obstacle. After
Calibration 5 tries alarm is signalled
/ first (RED Led ON) and the
installation actuator moves to initial
position. Doesn't respond to
control signal. Stroke value
is not updated beacuse out
of range
The actuator exits the
30/60 mm stroke range
Calibration and moves toward the new
/ first stroke limit signalling an
installation
anomaly (RED led on). The
actuator doesn't calibrate
the stroke
The actuator tries 5 times
against the new stall
Normal condition. After 10 sec. the
operation actuator updates the new
stroke lenght. During these
10 sec. RED led is ON
The actuator moves toward
the new stall condition with
a lower speed; after 10
Normal
sec. the actuator updates
operation
the new stroke value;
During these 10 sec. RED
led is ON
The actuator is still working

SHOOTING
CONDITION
Manual Calibration SW7 ON
The actuator pushes/pulls
2 times against endpoint
during calibration. Alarm Valve with
is signalled (RED led On) a stroke
and the actuator moves to length lower
the initial position. Doesn't than 5 mm
respond to the control
signal.
The actuator pushes/pulls
2 times against endpoint Valve with
during calibration. Alarm a stroke
is signalled (RED led On)
and the actuator moves to longer than
the initial position and then
it doesn't reposnd to the
control signal.
The actuator tries 5 times
against the new stall
condition. After 10 sec. the Valve stuck
actuator doesn't update the
new stroke lenght
The actuator moves toward
the new stall condition with connection
a lower speed. After 10
sec. the actuator doesn't
update the new stroke value damaged
