Troubleshooting For Parallel - Linak TECHLINE LA37 User Manual

Troubleshooting for Parallel

Symptom
Actuators do not
move
Actuators cannot
lift full load
Only for Non-critical Parallel:
Even if all actuators are not connected, the connected actuators will run after re-powering.
More information on page 52
Possible cause
The actuators are not properly connected
to the power supply
Wrong number of actuators in the system Check if the number of actuators in
Communication wires are not properly
connected
Signals run in/run out are not properly
connected
Position lost
Insufficient power supply
Overload in application
Action
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
the system match the number that was
ordered
Check the parallel communication wires
for all actuators
Check the wire connection on the
internal control unit
Disconnect all cables, connect the
actuator(s) to BusLink one at a time and
check the following:
- Reason for last stop (page 60)
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 54)
Check the power supply while the
actuator is running
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
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
