TROUBLE SHOOTING
Function
Valve 1 = accessory.
Voltage out.
Short circuit, probably on the cabling or in valve 1.
Open circuit, probably the conductor to the valve 1 or the nega-
tive conductor to the valve 1 or in the valve coil.
Valve 6 = accessory.
Voltage out.
Short circuit, probably on the cabling or in valve 6.
Open circuit, probably the conductor to the valve 6 or the nega-
tive conductor to the valve 6 or in the valve coil.
Valve 5 = accessory.
Voltage out.
Short circuit, probably on the cabling or in valve 5.
Open circuit, probably the conductor to the valve 5 or the nega-
tive conductor to the valve 5 or in the valve coil.
Valve 3 or 4 depending on the position of the weight
transfer switch
Voltage out.
Short circuit, probably on the cabling or in valve 3 or 4 depending on
the position of the weight transfer switch when the fault occurs is.
Breakage, probably the conductor to valve 3 or 4 or the nega-
tive conductor to valve 3 or 4 or in or in a valve coil.
Find the fault by first seeing in which position on the weight
transfer switch the fault occurs.
Valve 2 and 4, when lifting both are activated simultaneously.
Voltage out.
Short circuit, probably on the conductor to the valve 2 or to
valve 4. If LD4/LD15 as in the text above is OK find the fault on
valve 2. Open circuit, probably the conductor to valve 2 and 4 or
the negative conductor to the valve 2 and 4. These two valves
are connected in parallel and if there is only a fault on one valve
no fault indication is given by the LED.
Valve high speed.
Voltage out.
Short circuit, probably on the cabling to the valve for high
speed.
Open circuit, probably the conductor to the valve for high speed
or the negative conductor to the valve for high speed or in the
valve coil.
Valve differential lock.
Voltage out.
Short circuit, probably on the cabling to the valve for the diff
lock.
Open circuit, probably the conductor to the diff. valve or the
negative conductor to the diff. valve or in the valve coil.
