detected short to +Vbatt.
The Beacon light is faulty or disconnected
or the coil driver is faulty.
The Beacon light driver is shorted or the
beacon is faulty (open) or disconnected.
One of the following Slave module outputs
is detected short to -Vbatt : Swing or
Mast.
The Overload Light driver output is
shorted.
The Overload Light is faulty or discon-
nected.
The output of the Right Brake low side
driver is shorted to -Vbatt.
The output of the Left Brake low side
driver is shorted to -Vbatt.
The output of the Right Brake low side

CHECK
• Check the following Slave controller driver outputs
for a short circuit with +Vbatt : Swing CR3(8),
Mast CR3(9), Steer CR3(11), Jib Lift Down
CR3(33), Flow Direction CR3(34).
• Check each of the valve coils for correct impedance
(refer to Section 8).
• If the harness and the devices are correct and if the
fault appears at start up : Replace the Slave control-
ler.
• Check the beacon connections and wiring for inter-
ruptions.
• Replace the Slave controller if the beacon and its
harness are correct.
• Check the valve driver output CR2(11) for a short
circuit with -Vbatt.
• Check the beacon connections and wiring for inter-
ruptions.
• If the wiring is correct, the driver circuit is damaged
: replace the Slave controller.
• Check the valve driver output CR3(8) for a short cir-
cuit with -Vbatt.
• Check the valve driver output CR3(9) for a short cir-
cuit with -Vbatt.
• If the wiring is correct, the driver circuit is damaged
: replace the Slave controller.
• Check the valve driver output CR2(24) for a short
circuit with -Vbatt.
• If the wiring is correct, the driver circuit is damaged
: replace the Master controller.
• Check the overload light connections and wiring for
interruptions.
• Replace the Master controller if the light and its har-
ness are correct.
• Check the valve driver output CR2(4) for a short cir-
cuit with -Vbatt.
• If the wiring is correct, the driver circuit is damaged
: replace the Master controller.
• Check the valve driver output CR3(4) for a short cir-
cuit with -Vbatt.
• If the wiring is correct, the driver circuit is damaged
: replace the Slave controller.
• Check the right brake low side driver output CR2(4)
for a short circuit with +Vbatt.
• Check the brake coil for correct impedance (refer to
Section 8).
• If the wiring and the coil are correct, the driver cir-
cuit is damaged : replace the Master controller.
