Remote Control Panel (Status)
(1) "" indicator
(2) "SHUTDOWN" indicator
(3) "POWER ON" indicator
(4) "DIAGNOSTIC RESET" switch
(5) Status control module
(6) Engine control switch
(7) "EMERGENCY STOP" buttonThe yellow "" indicator (1) flashes or stays lighted to indicate the occurrence of an abnormal operating condition. A warning is not severe enough to cause a shutdown. However, this warning signifies a serious problem. If a warning occurs, a diagnostic code for the condition is logged in the engine control module. Correct the cause of the warnings as soon as possible to avoid problems with operation.The red "SHUTDOWN" indicator (2) illuminates continuously when an adverse operating condition causes a shutdown. A diagnostic code for the condition is logged in the engine control module. If the engine is shut down due to parameters that are out of acceptable limits, the red indicators on the status control module (5) will also illuminate."POWER ON" indicator (3) illuminates continuously when power is supplied to the control panel."DIAGNOSTIC RESET" switch (4) is a toggle switch that is used to clear diagnostic codes from the engine control module. The switch cannot clear individual codes. Use of the switch will clear all codes that are active in the engine control module. Do not clear the codes until the problems that caused the codes are addressed.Status control module (5) has several engine monitoring and control functions.Engine control switch (6) is used to control starting the engine and stopping the engine."EMERGENCY STOP" button (7) is used to stop the engine in an emergency situation. When the button is pressed, the status control module shuts off the fuel via the gas shutoff valve. The module also terminates the ignition. The "EMERGENCY STOP" button must be reset before the engine will start.Status Control Module
The status control module receives information from the following sources:
The operator
Magnetic pickups
Transducers (oil pressure and water temperature)
Optional remote sourcesThe basic performance of the status control module includes the following functions:When the status control module receives a signal to start the engine, the module enables fuel to flow to the engine. The module activates the starting motor. After the rpm for crank termination is achieved, the module deactivates the starting motor.When the status control module receives a signal to stop the engine, the module shuts off the fuel. The module sends a signal to the engine control module. The engine control module terminates the ignition.

(1) Liquid crystal display (LCD)
(2) Switch
(3) "OVERCRANK" indicator
(4) "LOW OIL PRESSURE" indicator
(5) "OVERSPEED" indicator
(6) "EMERGENCY STOP" indicator
(7) "HIGH COOLANT TEMPERATURE" indicator
(8) "AUXILIARY SHUTDOWN" indicatorLiquid Crystal Display (LCD) - Symbols for the following parameters are located under LCD (1). The LCD provides a digital display of the status of these parameters. When the status of a parameter is displayed, an arrow at the bottom of the LCD points the corresponding symbol. The display can be in metric units or English units.
Hour meter - When the arrow points to this symbol, the hours of engine operation are displayed.
Engine speed - When the arrow points to this symbol, the engine rpm is displayed.
System battery voltage - When the arrow points to this symbol, the voltage of the electrical system battery is displayed.
Engine oil pressure - When the arrow points to this symbol, the engine oil pressure is displayed.
Coolant temperature - When the arrow points to this symbol, the Coolant temperature is displayed.The parameters are displayed sequentially. To lock the display onto one of the parameters, press switch (2). To resume the sequential display, press the switch again.The LCD is also used to display diagnostic codes. A diagnostic code indicates that the system has detected a problem with a component that is associated with the status control module. When a diagnostic code is displayed, the arrow that indicates the display of the parameters will be missing. A flashing "dIAG" will be displayed. If more than one diagnostic code is present, the diagnostic codes will be displayed in sequence.To clear the diagnostic codes from the LCD, turn the engine control switch to the "OFF/RESET" position. For information on diagnostic codes, refer to the applicable Systems Operation/Testing and Adjusting and Troubleshooting manuals.The status control module has six indicators (Illustration 2) that indicate engine shutdowns. The shutdowns that are associated with the indicators are described below.
"OVERCRANK" - The status control module will deactivate the starting sequence if the engine fails to start within a programmed amount of time. Also, if the number of crank cycles are exceeded, the status control module will deactivate the starting sequence. Indicator (3) will flash. The engine control switch must be turned to the "OFF/RESET" position before another attempt to start the engine can be made.
"LOW OIL PRESSURE" - There are two setpoints for low oil pressure. The setpoints depend on the engine rpm. One setpoint is for engine rpm that is below the oil step speed setting. The other setpoint is for engine rpm that is above the oil step speed setting. If the engine oil pressure decreases below the setpoint, the fuel to the engine will be shut off. Indicator (4) will flash.
"OVERSPEED" - If the engine rpm exceeds the setpoint for overspeed, the fuel and the ignition will be shut off. Indicator (5)
