Location Of Components
Engine Supervisory System (ESS) Panel Location Of Components
(1) Junction box. (2) Status control. (3) Mode control switch. (4) Emergency stop push button.The Engine Supervisory System (ESS) Panel contains the Engine Status Control Module (SCM), an Emergency Stop Push Button (ESPB) and a Mode Control Switch (MCS).The Engine Status Control Module (SCM) is used to monitor engine parameters (oil pressure, coolant temperature, engine overspeed and over cranking of the starting motor), provides an engine protection system (two stage shutdown) and controls normal start/stop functions.An Emergency Stop Push Button (ESPB) is located on the remote control panel. When this button is pressed, the fuel is shut off and the engine ignition is turned off.
The Emergency Stop Push Button (ESPB) is not to be used for normal engine shutdown. To avoid possible engine damage, use the Mode Control Switch (MCS) for normal engine shutdown.
The Mode Control Switch (MCS) has four positions - "Off/Reset, Auto, Start and Stop".
Components On The Back Of SCM
(5) Fuses (F1 through F8). (6) Switch (overspeed verify).Function Of Controls
When the Emergency Stop Push Button (ESPB) is pressed, the gas shut-off valve is de-energized which stops the fuel supply to the engine. At the same time a relay is energized to turn the ignition off (the ground to the shutdown switch of the Electronic Ignition System control is opened).
The Emergency Stop Push Button (ESPB) is not to be used for normal engine shut down. To avoid possible engine damage, use the Mode Control Switch (MCS) for normal engine shut down.
To restart the engine, the emergency stop push button (ESPB) must be turned until it pops out. Above the emergency stop push button is the Mode Control Switch (MCS).The MCS determines the status of the remote control panel. In the automatic position (12 o'clock), the engine will start automatically whenever the remote initiating contact (IC) (optional) is closed and prelube is complete. The engine will also shut down after the initiate contacts open. An adjustable cool down time can be programmed to give a 0 to 30 minute cool down period before the engine shuts down. In the start position (3 o'clock), the engine will prelube, start and run as long as the MCS is in this position. In the stop position (6 o'clock), the fuel solenoid shuts the engine down after cool down. In the off/reset position (9 o'clock), the fault lights are reset and engine shuts down immediately. The power will be removed from the ESS as soon as the postlube cycle is complete.Engine Status Control Module
The bottom of the ESS panel contains the Status Control Module. This displays fault conditions and key engine parameters.The Engine Status Control Module (SCM) accepts information from the operator, magnetic speed pickup (MPU), pressure/temperature module and the Engine Supervisory System. This information is used to determine the "on/off" state of the engine's fuel and ignition system.
