DISC-CLUTCH 2633704 - Caterpillar

ECM
A comprehensive, programmable engine monitoring system is provided. The Electronic Control Module (ECM) can monitor parameters. The ECM can initiate an action if a specific operating parameter extends beyond the acceptable range. There are three possible actions by the ECM which are available: "", "DERATE" and "SHUTDOWN". However, not all of the actions are available for certain parameters.The Caterpillar Electronic Technician (ET) can be used in order to select the desired action by the ECM. Cat ET can be used to program the level for monitoring and the delay times for each action.Refer to Troubleshooting for detailed programming instructions.Engine Instrument Panel
The engine instrument panel is usually mounted on the engine. The engine instrument panel may be mounted up to 15 m (49 ft) away from the engine. The engine instrument panel includes the following controls:
Emergency stop push button
Engine Control Switch (ECS)
Local speed control (if equipped)
Alarm horn
ECM ready lamp
ECM active lamp
Emergency stop indicator
Engine overspeed indicator
Pyrometer (if equipped)
Marine Power Display (MPD)

(5) Engine control switch The following control panel switches are located inside the engine instrument panel:
Crank override switch
Prelube override switch
Protection override switch
Torque limit switch
Throttle control switch
Low idle switchThe crank override switch allows the operator to crank the engine with the engine starters. This overrides any other control or any engine protection system.The prelube override switch allows the operator to override the prelube pump sequence at the beginning of the crank cycle during engine start-up.The protection override switch provides an input for the user in order to override the engine protection devices.The torque limit switch enables the torque limiting feature.The throttle control switch allows engine speed to be controlled from a potentiometer on the panel, if equipped.The low idle switch provides the ability to control engine rpm. When the switch is enabled, the engine will operate at the low idle rpm that is programmed.Refer to Illustrations 2 and 3.
