"ENGINE SPEED" Gauge
The "ENGINE SPEED" gauge has a digital display. The gauge displays the rotational speed of the crankshaft.The signal for this gauge is provided by a magnetic pickup that is mounted in the flywheel housing. The signal is used by the Engine Speed Switch. Engine RPM is displayed on the gauge regardless of the PLC status or the PC status.

"STARTING AIR PRESSURE" Gauge
The "STARTING AIR PRESSURE" gauge indicates the air pressure for the starting motor and the shutoffs. This gauge is not affected by the "HORN SILENCE/LAMP TEST" switch or the "RESET" switch. The gauge indicates the air pressure for the starting motor and the shutoffs regardless of the PLC status or the PC status.The start air pressure must be a minimum of 482 kPa (70 psi) and a maximum of 1550 kPa (225 psi). Starting air pressure above 1550 kPa (225 psi) is abnormal. Stop the engine and diagnose the cause. Running the engine during abnormal conditions may cause engine damage.

"SUMMARY SHUTDOWN" Indicator Lamp
The "SUMMARY SHUTDOWN" lamp displays the status of the engine protection shutdown system.A red "SUMMARY SHUTDOWN" lamp indicates that a engine protection shutdown has occurred. The exact shutdown is annunciated on the PC window. A flashing "SUMMARY SHUTDOWN" lamp indicates an shutdown that is not acknowledged. A solid "SUMMARY SHUTDOWN" lamp indicates that the shutdown has been acknowledged.The cause of the shutdown is provided by the display screen. To acknowledge the indicator, turn the "HORN SILENCE/LAMP TEST" switch to the "HORN SILENCE" position. Correct the condition before restarting the engine. The control panel must be reset before the engine can be restarted. To reset the control panel, turn the "OFF/RESET, LOCAL, and REMOTE" switch to the "OFF/RESET" position. The air shutoff is activated for any shutdown. The air shutoff must also be reset before the engine can be restarted. If an overspeed shutdown occurs, the Engine Speed Switch must also be reset.Note: When a shutdown occurs the air damper closes. This secures the intake air. The air damper must be reset in order to start the engine. "SUMMARY ALARM" Indicator Lamp
The "SUMMARY ALARM" lamp provides a summary of the active MMS alarms. A red "SUMMARY ALARM" lamp indicates an alarm condition. Specific information on the alarm is provided on the PC window. A flashing "SUMMARY ALARM" lamp indicates an alarm that has not been acknowledged. A solid "SUMMARY ALARM" lamp indicates that the alarm has been acknowledged. The lamp will remain illuminated until the
