Indicator lamp for the engine | |
The indicator lamp indicates when the engine is running.
The lamp operates on 24 volts. The lamp has a green lens that displays "ENGINE RUN". Use the lamp test switch in order to test the lamp.
The lamp is connected to the circuit of the run relay. The lamp will illuminate when the engine is running. The lamp shuts off when the shutdown circuit is active.
Indicator Lamp (Engine Prelubrication)
| | |
| Illustration 2 | g00792738 |
Indicator lamp for engine prelubrication | |
The lamp indicates the prelubrication of the engine.
The lamp operates on 24 volts. The lamp has a green lens that displays "ENGINE PRELUBE".
The lamp is connected to the circuit of the "starting oil" relay. The lamp indicates that the engine has oil for starting. The lamp will illuminate when the lubrication of the engine exceeds 9 ± 3 kPa (1.3 ± 0.4 psi) for intermittent prelube systems. The lamp will illuminate when the lubrication of the engine is detected for continuous prelube systems. The lamp shuts off when the engine is running.
Indicator Lamp (Alarm)

Indicator lamps for alarms | |
The alarm lamps are available on the annunciator panel only. There are 16 indicators that are available for the different systems. The lamp indicates the alarm that is active.
The lamps operate on 24 volts. The lamps are activated by outputs from the programmable logic controller. The lamps have amber lenses that display one of the following alarms.
- Engine speed pickup
- Low engine oil level
- Low engine oil pressure
- Particle detection
- High engine oil temperature
- High jacket water coolant temperature
- Low jacket water coolant level
- Tripped breaker
- High manifold air temperature
- High exhaust manifold temperature
- Low starting air pressure
- High fuel temperature
- Low fuel pressure
- Low jacket water pressure
- Low aftercooler/oil cooler water pressure
- Spare
Use the lamp test switch in order to test the lamps.
The lamp is connected to the particular alarm circuit. The lamps indicate that an alarm condition is present. When an alarm condition is present, the indicator will flash. The lamp will flash until the alarm is acknowledged. After the alarm is acknowledged, the lamp will stay on. The lamp will stay on until the alarm condition has been cleared and the reset button has been depressed.

Indicator lamps for shutdowns | |
The shutdown lamps are available on the annunciator panel only. There are 8 indicators that are available for the different systems. The lamp indicates the shutdowns that are active.
The lamps operate on 24 volts. The lamps are activated by outputs from the programmable logic controller. The lamps have red lenses that display one of the following alarms.
- Engine overspeed
- High crankcase pressure
- Low engine oil pressure
- Particle detection
- High engine oil temperature
- High jacket water coolant temperature
- Low jacket water coolant level
- Spare

Indicator Lamp (Programmable Logic Controller)
| | |
| Illustration 5 | g00792738 |
Indicator lamp for programmable logic controller | |
The indicator lamp for the programmable logic controller (PLC) is available on the annunciator panel only. The lamp indicates that the programmable logic controller is operating.
The lamps operate on 24 volts. The lamp has a green lens that displays "PLC RUN".
Use the lamp test switch in order to test the lamp.
The lamp is connected to an output of the PLC. The lamp will be illuminated whenever the PLC is executing the program for the annunciator panel. The lamp will be off if the controller is not in the run mode or the controller has a major fault.
Note: When the lamp is not on, the annunciator panel may not be working.
