MACHINEELECTRONICCONTROLSYSTEM

The Machine Electronic Control System on the 735/740 Articulated Dump Trucks monitors various machine systems and then conveys the machine status to the operator. The Machine Electronic Control System includes the Instrument Cluster, an Engine ECM, and a Transmission/Machine Control ECM. The Messenger Module is available as an optional Service Enabled Attachment (SEA) in order to convey additional information to the operator.

The Instrument Cluster is a cab display that shows the operator the status of various machine parameters as well as alerts the operator of specific machine conditions. The Instrument Cluster is driven by the Transmission/Machine Control ECM and the Engine ECM via the Controller Area Network (CAN) Data Link.

The Messenger display is an LCD module with four operator actuated pushbuttons which will allow the operator to access menus to display machine status along with operator information. The Messenger display is driven by the Transmission/Machine Control ECM and the Engine ECM over the Cat Data Link (CDL).
