Control Panel (Status-Timing) Location Of Components
Control Panel (Status-Timing) Location Of Components
(1) Junction box. (2) Timing control module. (3) Emergency stop push button. (4) Engine status control module. (5) Engine control switch.
Inside Of Junction Box Door Location Of Components
(2) Timing control module. (3) Emergency stop push button. (4) Engine status control module. (5) Engine control switch. (6) Junction box door.The Control Panel (Status-Timing) contains the Timing Control Module (TCM), Engine Status Control Module (SCM), an Emergency Stop Push Button (ESPB) and an Engine Control Switch (ECS).The Engine Status Control Module (SCM) is used to monitor engine parameters (oil pressure, coolant temperature, engine overspeed and over cranking of the starter motor), provides an engine protection system (two stage shutdown) and controls normal start/stop functions.The Timing Control Module (TCM) monitors the engine for detonation through the two detonation sensors. If detonation is detected the timing is retarded. If the engine stays in detonation after the timing has been retarded, the TCM will shut down the engine. The TCM also controls timing based upon engine speed.An Emergency Stop Push Button (ESPB) is located on the 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 Engine Control Switch (ECS) for normal engine shutdown.
The Engine Control Switch (ECS) has four positions - "Off/Reset, Auto, Manual and Stop". For location and specifications on components located on the engine, make reference to the respective Engine Service Manual.
Components On The Back Of SCM (4)
(7) Fuses (F1 through F8). (8) Switch (overspeed verify). For point to point wiring diagrams and schematics, make reference to the Electrical Schematic, System D.C. Schematic.Function Of Controls
The Emergency Stop Push Button (ESPB) (3). When this button is pressed, the gas shutoff 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 magneto is not grounded, but the ground to the interface box from the timing control is opened).
The Emergency Stop Push Button (ESPB) is not to be used for normal engine shutdown. To avoid possible engine damage, use the Engine Control Switch (ECS) for normal engine shutdown.
To restart the engine, the emergency stop push button (ESPB) must be turned until it pops out. Below the emergencey stop is the Engine Control Switch (ECS) (5).The ECS determines the status of the control panel. In the automatic position (3 o'clock), the engine will start automatically whenever the remote initiating contact (IC) (line 47) (optional) is closed. The engine will also shut down after the initiate contacts open. An adjustable cooldown time can be programmed to give a 0 to 30 minute cooldown period before the engine shuts down. In the manual (run) position (6 o'clock), the engine will start and run as long as the ECS is in this position. In the stop position (9 o'clock), the fuel solenoid shuts
