21.1.3. Self-protection in case of overload or breakage of the push-pull cables
The 2 digit display on the actuator is a helpful instrument during trouble shooting. The actuator has a built-in
control that generates a failure alarm in case the push-pull cable becomes “too hard” or in case the cable’s
stroke is not set correctly (beyond the maximum stroke allowed by the actuator).
If one of the above mentioned cases occurs:
the systems stops (no movements on the push-pull cables)
on the display of the actuator appears an “E” or a “P” on the side of the overloaded cable
all the LEDs of the command stations start to blink.
Error “E” stands for overload failure
Error “P” stands for position failure (missed position target)
In case this alarm is present, turn off the system and verify the causes that might have generated the alarm:
•
strokes and bending radius of the push-pull cables
•
performance of the push-pull cables and if they are not functioning correctly, replace them.
Restart the electronic control system only if you have removed the causes of the not correct functioning.
An “E” or “P” will be shown
on the side of the actuator
with the cable overload
error or the cable
positioning error
An “E” or “P” will be
shown on the side
of the actuator with
the cable overload
error or the cable
