Troubleshooting for Parallel
Only for Non-critical Parallel:
Even if all actuators are not connected, the connected actuators will run after re-powering.
More information on page 54
Symptom Possible cause Action
Actuators do not
move
The actuators are not properly connected
to the power supply
Check the connection to the power supply
or the external control unit (if any)
Please make sure that the power
supply polarity is properly
connected, otherwise you might
damage the actuator
Please see non-critical info below
Wrong number of actuators in the system Check if the number of actuators in
the system match the number that was
ordered
Communication wires are not properly
connected
Check the parallel communication wires
for all actuators
Signals run in/run out are not properly
connected
Check the wire connection on the
internal control unit
Position lost Disconnect all cables, connect the
actuator(s) to BusLink one at a time and
check the following:
- Reason for last stop (page 62)
After everything is connected, put power
on all actuators at the same time. Then
wait 10 seconds before the Run In/Run
Out signals are activated
If this does not work, initiate the Parallel
manual service mode (page 56)
Actuators cannot lift
full load
Insufficient power supply Check the power supply while the
actuator is running
Overload in application Reduce the load
Connect actuator(s) to BusLink one at a
time and check the following:
- Type of chosen Parallel system
- Reason for last stop (page 60)
- Current cut-off levels in both
directions
Please see non-critical info below
After everything is connected, put power
on all actuators at the same time. Then
wait 10 seconds before the Run In/Run
Out signals are activated
