Manual Extract: PRIMARY HYDRAULIC POWER SYSTEM Electro-hydraulic remote valve

Static description Activity
Each remote valve has its own built in microprocessor which controls the oil flow through a solenoid activated valve, based on inputs received from the operator controlled switches.

Each remote valve is connected into the electrical CAN BUS system to the RK / RL control module, located behind the drivers seat. Each remote valve can also detect system faults and send a message to the RK / RL module which in turn sends a signal to allow a fault code to be displayed on the instrument cluster.
Refer to the fault code list for relevant information.

Control Levers
The electro-hydraulic remote valves are operated by control levers in the right-hand console. Each control lever is coloured to correspond to the color on the remote valve. A maximum of four electro-hydraulic remote valves may be fitted.
