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
