Topcon Paver System Five Operator’s Manual
9-6
Control Box Symptom 5
“The tow point cylinder is moving in the wrong direction.”
Probable Cause
Machine is incorrectly wired or hydraulically connected.
1. Check that the machine is properly wired and
hydraulically connected to the valve. A raised jog
switch should make the cylinder go up, lowering the
jog switch should make the cylinder go down.
2. Check that the proper cables have been supplied for
your machine.
3. For System Four, if “OIN” setting is in the performance
menu, make sure it is in the off position.
4. Make sure the screed lift cylinders are in the float
position and not supporting the screed.
Control Box Symptom 6
“The tow point cylinder is moving ‘too fast’ or ‘too slow’.”
Probable Cause
The paving machine's hydraulic flow adjustment is
incorrect, or the control box Valve Offsets or Gain
Adjustments are not correct.
1. Refer to paver manufacturers recommended flow
adjustment setting for the time it takes the hydraulic
cylinder to complete a full stroke of travel. Typically
between 12 to 15 seconds.
2. Adjust Gain Performance Settings.
Factory setting is 25.
3. Adjust Valve Offsets. Refer to Valve Offset section in
the Performance Section within this Manual.
