Manual Extract: Hydraulic controls

All these remote hydraulic controls are hard wired directly into the armrest controller. Each remote control lever actuates a potentiometer within the armrest control console. As a remote control lever is actuated the armrest controller reads the potentiometer setting and sends a signal through the Case Data Bus (CDB) to the remote controller. The remote controller sends the signal onto a proportional solenoid which shifts the main valve spool allowing flow through to the respective remote coupler.

The remote controller will report any problems directly to the instrument controller. The instrument controller will display any system faults or fault code information through the standard instrumentation display.
When a fault occurs, a 3 second continuous audible alarm will sound. The audible alarm will stop after 3 seconds.
Once the fault has been corrected the fault codes should be erased. To erase the fault codes from a controller, press and hold both the INCR and DECR keys for 10 seconds.
