16.1.3 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 an alarm signal 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.
An "E" or "P" will be shown on
the side of the actuator with
the cable overload error or the
cable positioning error
"E" stands for overload failure.
"P" stands for position failure (missed position target).
In case one of the two alarms occurs, turn off the system and verify the causes that might have generated the alarm:
• errors in stroke setting, bending radius of the push-pull cables too small or push-pull cable "squeezes"
• performance of the push-pull cable too low or control cable degenerated over time: if push pull cables are not per-
forming correctly, they must be replaced.
Restart the electronic control system only if you have removed the causes of the not correct functioning.
