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 10A fuses in the 3 pin plug, check the condition of these.
Controller not counting
turntable revolutions
Check the turntable magnet and the sensor located on the chassis.
Check the controller communication cable is connected and not damaged.
Note if the table revolutions are not being counted then the Autostop and the automatic film release will not function.
Turntable Autostop is not
holding lever
The Autostop should hold the turntable lever engaged after 1 revolution of the turntable.
Check the electric supply to the Autostop electromagnet.
Check the turntable control cable adjustment to make sure it is pushing the valve spool fully to the electromagnet. Adjust cable if
necessary.
Film Cut and Start Cylinder does extend to
cut the film when tipping.
Check operation of diverter valve on tipping frame. The spool in the valve should spring out when the link is pulled during tipping.
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. Recharge the ac-
cumulator.
The electric poppet valve that activated by the controller is not opening. It should start opening on the second (adjustable) table
revolution and stay open for 3 (adjustable) seconds.
Check the wiring to the valve.
