Lock malfunction
Microswitch malfunction (feedback signal)
Check:
- Check Micro Switch connections, Cables, WR1 and WR2 (Weight Released)
plugs
- Check that the locks retract when the LW1 and LW2 (Lock Weight) plugs are
disconnected
- Use button [Lock Weight] to check LW1 and LW2 outputs and Lock function
Error 792: Weight Released NOT Activated
Weight Not Released. The Upper Locks (Weight Locks) are not retracted when
they should be. Or the feedback signal (Micro Switches) in the Upper Locks
are not activated when they should be. That means that it is not possible
to lock or unlock the weights. Neither it is to perform drops.
Possible causes:
Electrical break
Lock malfunction
Micro Switch malfunction (feedback signal)
Check
- Check Micro Switch connections, Cables, WR1 and WR2 (Weight Released)
plug
- Check LW1 and LW2 (Lock Weight) plugs, cables, connections at locks
- Use button [Lock Weight] in CP15 to check LW1 and LW2 outputs and Lock
function
Error 793: Plate Released Activated
Plate Released. The Lower Locks (Transport Locks) are retracted when they
should not be. Or the feedback signal (Micro Switches) in the Lower Locks
are activated when they should not be. Therefore, the plate cannot be
lowered, nor raised.
Possible causes:
Electrical short
Lock malfunction
Wrong feedback signal from microswitches (it could be that the lock is not
extended but the feedback signal is wrong)
Check:
- Check Micro Switch connections, Cables, PR (Plate Released) plug in CP15
- Check that the locks extend when the RP1 and RP2 (Release Plate) plugs
are disconnected
- Use button [Release Plate] in CP15 to check RP1 and RP2 outputs and
Release function
Error 794: Plate Released NOT Activated
Plate not Released. The Lower Locks (Transport Locks) are not retracted
when they should be. Or the feedback signal (Micro Switches) in the Lower
Locks are not activated when they should be. The plate cannot be lowered,
nor raised. It can be one or both locks malfunctioning at the same time.
Possible causes:
Electrical break
Locks malfunction
Micro Switch malfunction (the locks actually move as they should but the
feedback signal is wrong)
Check
- Check Micro Switch connections, Cables, PR (Plate Released) plug
- Check RP1 and RP2 plugs (Release Plate), cables, connections at solenoids
- Use button [Release Plate] in CP15 to check RP1 and RP2 outputs and
Release function
