TROUBLE SHOOTING GUIDE
PROBLEM - INFEED CONVEYOR NOT OPERATING USING THE RADIO OR TETHER CONTROLS:
(All other functions are working)
Possible Cause Possible Solutions
No electrical signal to the solenoid Check for electrical power at the solenoid while
control valve. Engaging the switch on the remote used to operate
the Infeed Conveyor. If you have electrical power at
the solenoid on the control valve then you will need to
refer the electrical schematic supplied with the
machine to trace the problem. A wire may be broken
or have a faulty relay inside the engine control panel.
Faulty switch in Remote Control. If using the Radio Remote, switch to the Tether
Remote and vice versa to determine if the problem
may be in the remote.
PROBLEM - FEEDWHEEL WILL NOT TURN USING THE MANUAL CONTROLS:
(All other hydraulic systems are working)
Possible Cause Possible Solutions
Material wedged or stuck preventing Raise and secure the Feedwheel using all safety
the Feedwheel from turning. devices. With the machine shut down, check around
Feedwheel looking for anything that may have it bound
up.
Check to see if the drive key in the Feedwheel Check shaft for damage and replace key.
hydraulic motor shaft has sheared.
Feedwheel bearing failure. Raise and secure Feedwheel following all safety
procedures and check bearing. Replace if necessary.
Check the flow controls to see if they are on. If the flow controls are opened up too far the
Feedwheel can stop under heavy load.
Low hydraulic system pressure. A quick check of the hydraulic pressure can be done
by placing the pressure gauge into the diagnostic port
provided on the control valve. Put the Feedwheel
manual control valve into forward or reverse position
to check the Feedwheel working hydraulic pressure.
A 1200 PSI (83 bar) reading would indicate that the
Feedwheel is mechanically stalled by some obstructing
material. A very low pressure reading would indicate a
hydraulic problem with the pressure relief valve or
the hydraulic pump. See “ Procedure for checking
hydraulic pump and relief valve setting” in the
Hydraulic Section.
