CHECK
• 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.
• Check the left brake low side driver output CR3(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 Slave controller.
CHECK
• Change the Master controller.
• Change the Slave controller.
• Power down and allow to cool.
• Do not operate in ambients over 60°C.
• Check for jammed or obstructed right drive motor.
• Check for excessively high drive motor current con-
sumption while driving on the level ( over 120A ).
• Check for jammed or obstructed telescopic mast.
• Check for excessively high pump motor current
consumption while raising the jib with the platform
empty (battery output current over 90A).
• Check the Master module for proprer installation
(refer to § 8-4).
• If the module is cold when the fault appears :
replace the module.
• Power down and allow to cool.
• Do not operate in ambients over 60°C.
