CAN NetworkCircuit BreakersAttachment ControlsSpeed ControlsWiringA Controller Area Network (CAN) is used on the M-B Multi ServiceVehicle to control all hydraulic and engine functions. The CAN isdesigned with software switches that compliment other switches andthe joystick. Together, this system activates electric solenoids thatcontrol hydraulic valves. The main interface to the system is theMonitor Diagnose Control (MDC).The electrical system is protected by circuit breakers of various sizeslocated in the rear control panel in the engine enclosure.In compliance with engine manufacturer’s requirements, the powersupply for electronic control modules is protected by a fuse pack.These fuses will be located in the Cab Subpanel.All attachment hydraulic functions, PTO engagement, and somevehicle control selections are controlled by the MDC and joystick.Vehicle controls include the engine throttle and a foot pedal. Each ofthese are set using the MDC screens and the joystick to deliver acontrolled variable voltage to an actuator.Engine speed is controlled by an electronic control module provided bythe engine manufacturer. The operator in the cab uses MDC screensand joystick which are networked to the Electronic Control Module(ECM) to set desired engine operating speed.The auxiliary hydraulic flow rate is controlled from the operatorsposition in the cab by means of the MDC. The ground drive speed iscontrolled by means of the foot pedal. A variable current is delivered toan electronic displacement control (EDC) on each hydraulic pump forthe particular function. The variable current determines the angle of thepump swash plate which in turn determines pump displacement.Wiring in the system is color and number coded for ease of tracing,maintenance, and troubleshooting.M-B Multi-Service Vehicle Page 3.20 Vehicle Information© 2008 M-B Companies Inc.All Rights Reserved
