Troubleshooting For Parallel - Linak TECHLINE LA33 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 47
Possible cause
The actuators are not properly connected to
the power supply
Wrong number of actuators in the system
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
Check if the number of actuators in 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 55)
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 49)
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 55)
- 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
