Figure 3-6: Typical Engine Status Displays
POM0027, 0028
The Engine Status Display is either a group of gauges and indicator lights or an electronic display that gives you
critical information on engine performance.
You must watch this information often during pump operation, and react to any abnormal readings.
Engine information includes:
•
Engine Speed: shows current engine speed in RPMs.
• Engine Oil Pressure Gauge: shows engine oil pressure.
• Engine Temperature Gauge: shows oil temperature of the engine.
• Electrical System Voltage Meter: measures the voltage level of the vehicle's battery system.
• Stop Engine Light
If the Stop Engine light turns ON, the engine's ECU (electronic control unit) has detected a critical error condition.
That means engine failure is possible at any moment. Read and study the engine manufacturer's operations manual
so you know how to react.
Practice your reaction to all different kinds of failure
. You need to be prepared in
advance so you can react properly in an emergency.
Fire apparatus programming does not allow a critical engine failure to automatically stop the engine. The engine will
continue to run until it self-destructs or fails.
It is your judgment call to balance the risks of damage to the engine with the need for the fire apparatus to remain
operational.
Replace apparatus when STOP ENGINE light is ON.
Engine can fail at any time without further warning.
Engine failure will stop water flow to attack lines, putting fire-fighting personnel in danger.
