Troubleshooting
TONGUE CYLINDER CIRCUIT
PRObLEM POSSIbLE CAUSE SOLUTION
Tongue cylinder will not extend,
but will retract.
No power to solenoid valve coil in port V10
and/or V14. Both must be energized.
Check wiring between control console and
solenoid coils looking for damaged wires
and poor connections.
Solenoid valve coil defective. Switch coil from port V13 with V10. If
tongue still will not extend, switch coil
from V14 with V13. It is not necessary to
remove any solenoid wire connections. All
three solenoids are normally energized
when tongue switch is energized.
Replace defective coil.
Solenoid valve cartridges in port V10 and/
or V14 stuck closed.
Switch cartridge from port V10 with
cartridge in port V13. If tongue cylinder
retracts, replace defective cartridge from
port V10. If problem continues, switch
cartridge from port V14 with cartridge in
port V13. Replace defective cartridge.
Tongue cylinder will not extend
but tongue lock cylinder extends.
Pressure relief valve in port V11 stuck
closed or pressure setting too high. (Valve
is factory set to open at 1000 PSI.)
Replace or adjust pressure relief valve. To
adjust, loosen lock nut and turn counter
clockwise to decrease pressure.
Tongue hook does not release
before tongue starts to extend.
Solenoid valve cartridge in port V11 stuck
open or pressure setting too low. (Valve is
factory set to open at 1000 PSI.)
Replace or adjust pressure relief valve. To
adjust, loosen lock nut and turn clockwise
to increase pressure.
Tongue cylinder will not retract,
but will extend.
Solenoid valve coil in port V13 defective. Switch coil from port V13 with coil from
port V14. If coil from port V13 is bad,
tongue will extend but not retract. Replace
defective coil.
Solenoid valve cartridge in port V13 stuck
closed.
Switch cartridge from port V13 with
cartridge from port V14. If cartridge is bad,
tongue will extend but not retract. Replace
defective cartridge.
Tongue extends with switch off. Solenoid valve cartridge in port V10 and
V14 stuck open.
Replace solenoid valve cartridge.
Tongue retracts with switch off. Solenoid valve cartridge in port V13 stuck
open.
Replace solenoid valve cartridge.
Tongue latch releases. Tongue
extends slowly while planting.
Latch cylinder or tongue cylinder leaking
internally.
Pressure check latch and tongue cylinders.
Repair leaking cylinder(s).
