9. TROUBLESHOOTING
Area Problem Remedy
Hydraulic Oil supply under high
pressure immediately the
tractor hydraulic lever is
engaged.
Hydraulic feed or return couplings not properly engaged.
Hydraulic couplings connected to a double acting supply on the tractor and supply is in the wrong direction. This can cause the
poppet in the return coupling to lock closed. The coupling will have to be loosened to relive the locking pressure between the check
valve and the coupling.
Controller Controller does not power
up.
Check the switch on the back of the controller.
Make sure the 3 pin power supply plug is securely connected.
There are two 15A fuses on the power cable, check the condition of these.
Controller not counting
turntable revolutions
Check the turntable sensor located on the tipping frame. This has an LED indicator that lights when the metal come within 5mm of
the tip.
Check the controller communication cable is connected and not damaged.
Note if the table revolutions are not being counted many other automatic functions will not automate because they are triggered by
the count.
Film Cut and Start Cylinder only partially
extends.
The oil pressure in the accumulator is over 60 Bar usually caused by leaking cylinder seals. Get this checked by a service engineer.
Check operation of diverter valve on tipping frame.
Cylinder does not retract
to release the film during
wrapping.
This cylinder is opened by the oil held under pressure in the accumulator. If the pressure is too low it will not open. Please get your
dealer to recharge the accumulator pressure.
Check the wiring to the control valve.
