Electronic instrument panel (1) Main display module (2) "SCROLL" switch (3) "CLEAR/MODE" switch (4) "LH/RH" switch (5) "EMERGENCY STOP" button (6) Action alarm (7) "ALARM SILENCER" switch (8) Backup ECM ready indicator (9) Backup ECM in control indicatorThe electronic instrument panel is the center for engine control and for information about engine operation. Each component of the instrument panel is described below.Main display module (1) - This module is the main component of the instrument panel. The module receives information from the switches, sensors and other electronic controls on the engine via the CAT Data Link. The module processes the information. The information is output to the gauge clusters and/or the action alarm."SCROLL" switch (2) - The main display module is capable of five different modes of operation. The "SCROLL" switch is used to display the various parameters that are within each mode. See the "Main Display Module" topic."CLEAR/MODE " switch (3) - This switch is used for selecting among the main display module's five modes of operation. This switch is also used for clearing information from the main display module."LH/RH" switch (4) - This toggle switch is used in order to display the exhaust temperature and the inlet air restriction for the left side or the right side of the engine."Emergency Stop" button (5) - This button is used to stop the engine quickly in an emergency situation. When this button is pressed, the fuel injection is disabled and the air shutoffs are activated.Action alarm (6) - Annunciation of the alarm informs the operator of an abnormal operating condition or a problem with the monitoring system."ALARM SILENCER" switch (7) - This push button allows the operator to silence the action alarm. The switch will silence the alarm for five minutes. If the condition that initiated the alarm is not corrected within the five minute period, the alarm will sound again.Backup ECM ready indicator (8) - This green indicator illuminates in order to indicate that the backup electronic control module (ECM) is ready for use.Backup ECM in control indicator (9) - This yellow indicator illuminates in order to indicate that the primary ECM is no longer in control of engine operation. The backup ECM is in control.Engine control switch - This switch is used to control the engine operation. The switch has these four positions: "AUTO", "MAN.START", "COOLDOWN/STOP" and "OFF/RESET"."AUTO" - This position enables the operator to control the engine from a remote location."MAN.START" - When the switch is turned to this position, the engine will start. The engine will continue to run until the ECM receives a shut down signal."COOLDOWN/STOP" - This position is used for manual engine stopping. If the cooldown feature is programmed, the engine will operate for a cool down period. After the cooldown, the fuel injection is terminated in order to stop the engine. If the cooldown feature is not programmed, the engine will stop immediately. The power to the control panel is maintained when the switch is in this position."OFF/RESET" - When the switch is turned to this position, power is removed from the control panel. This position will also reset the system if any events have occurred. If the engine is operating, the engine is immediately shut off. This position is not recommended for normal engine shutoff.Note: The engine control switch is mounted within the instrument panel that is located on the right side of the engine. The engine control switch is locked into the AUTO position with a pin. The operation of the engine is normally controlled through an instrument panel that is at a remote location.Main Display Module
Indicators
The indicators illuminate in response to information that is received from the ECM via the CAT Data Link.Note: The indicators will illuminate if a setpoint that is programmed into the monitoring system for a parameter is reached. For information on the setpoints, refer to this Operation and Maintenance Manual, "Monitoring System" topic (Operation Section).

Indicators for the main control module (1) Active diagnostic code and engine shutdown (2) Low system voltage (3) Engine overspeed (4) Overcrank (5) Not in AUTO (6) Low engine oil pressure (7) High coolant temperature (8) Low coolant temperature (9) Low coolant level (10) Low fuel level
Active diagnostic code and engine shutdown (1) - This RED indicator illuminates when any of the following conditions occur:
An engine shutdown is initiated by the ECM.
A diagnostic code is active.
An event code is active.
Low system voltage (2) - This RED indicator illuminates if the system voltage (battery and alternator) that is supplied to the ECM is below the setpoint that is programmed. The indicator will also illuminate if the battery charger (if equipped) is not charging.
Engine overspeed (3) - This RED indicator illuminates when the ECM has detected an engine overspeed condition.
Overcrank (4) - This RED indicator illuminates if the engine fails to start within the time that is programmed for the crank cycle. If the engine fails to start within the preprogrammed amount of time, the system will terminate the starting sequence. In this case, the overcrank indicator (4) will flash. Another attempt to start the engine cannot be made until the engine control switch (ECS) is placed in the OFF/RESET position.
Not in AUTO (5) - This RED indicator illuminates when the engine control switch is not in the "AUTO" position. Automatic starting and stopping from a remote location is only possible when the engine control switch is in the "AUTO" position.
Low engine oil pressure (6) - This YELLOW indicator illuminates when the engine oil pressure is below the setpoint that is programmed at the factory. The setpoint is based on a map of minimum oil pressure versus engine speed. This value cannot be reprogrammed.
