Thrust actuator ARI-PACO
®
2G 1,6D/Y
9.1 ARI-PACO
®
2G 1,6D
Fault
Possible Causes
Remedy
Thrust actuator fails to move
Power failure
Ascertain and eliminate cause
Fuse has blown
Replace fuse
Thrust actuator not properly
connected
Rectify connection on thrust actuator
in accordance with wiring diagram
Short circuit due to:
- moisture
Ascertain exact cause,
- Dry the thrust actuator and
eliminate leakage
- wrong connection
- Rectify connection on thrust
actuator in accordance with wiring
diagram
- motor has burned out
- Check whether the mains voltage
agrees with the voltage specified
on the rating plate. Have motor
changed.
Connector contacts not plugged in/
not properly plugged into jack strip
Insert connector firmly in jack strip
thus affected
Thrust actuator alternates
between clockwise and counter-
clockwise rotation
Motor operating capacitor defective Have motor operating capacitor
replaced.
Thrust actuator fails to run to
final positions and also produces
chatter
Load-dependent travel switches out
of / defective
Remove thrust actuator and send to
factory for repair
Voltage drop due to excessively long
connecting cables or inadequate
conductor cross-section
Lay connecting cables in
accordance with requisite output
Mains fluctuations beyond
permissible tolerance travels
Arrange for "clean" mains system
within requisite tolerances
System pressure too high
Reduce system pressure
Periodic failure on thrust actuator Loose connection on feedline
Tighten connections on terminal
strips
Thrust actuator is switched off in
retracting direction prior to load-
dependent switch (three-way
valve)
Travel switch S3 not set
corresponding to use
Set travel switch S3 in accordance
with operating instructions
