LOFA EP250 Operation and Troubleshooting

6 463-3000-01 Rev C.1 - 28-Feb-2007

the shutdown input to ground can cause fault indications. The system can be configured for auxilary 1 failure

to indicate only.

A blinking AUX 1 LED indicates SW input failure. The control system typically senses failure using a ground

contact switch. The SW input is equipment specific and determined by the equipment manufacturer. A

defective switch or shorting the shutdown input to ground can cause fault indications.

AUX 2 LED (Red)

A solidly illuminated AUX 2 LED indicates auxiliary 2 failure (i.e., air flow restriction, fuel level, etc.) but by

default does not cause a shutdown. The control system typically senses failure using a ground contact switch.

Auxiliary inputs are equipment specific and determined by the equipment manufacturer. A defective switch or

shorting the shutdown input to ground can cause fault indications. The system can be configured for auxilary

2 failure to indicate only.

Preheat LED (Red)

A solidly illuminated Preheat LED is the system preheat indication. When the LED extinquishes the preheat

period is complete and the engine may be cranked. The LED illuminates again to indicate afterglow.

Gauges

Voltmeter

The voltmeter is connected to the fuel run/stop solenoid output. If the voltmeter does not indicate in the run

position, this indicates a problem with the solenoid circuit. A battery voltage reading of approximately 14

volts on a 12 volt system (28 volts on a 24 volt system) while the engine is running indicates the battery is

charging properly.

Tachometer

The tachometer indicates engine RPM using a frequency signal derived from the engine. This signal may be

provided by an alternator frequency tap, proximity switch. An optional amplifier/divider can be added for

use with a magnetic pickup.

Note

If the alternator is not excited (not charging),

no frequency is generated and the tachometer will indicate 0 RPM.

The tachometer is factory calibrated to indicate correctly when the panel is preconfiguring or field calibrated

with a Diagnostic Programming Gauge (DPG). The tachometer can be calibrated using standard procedures

if the configuration is not performed (see Tachometer Calibration Instuctions for details).

Oil Pressure Gauge

The gauge measures oil pressure with a resistance sender on the engine referenced to ground. When a

sender/switch combination is used on the engine, the marking G generally indicates the gauge terminal. The

gauge expects a low resistnace for low pressure and a higher resitance for higher pressure. If the gauge is

not connected to the sender, the gauge will read full scale (pegged). A defective sender or shorting the

gauge input to ground will cause the gauge to read 0 pressure. When using sender/switch combinations,

swapping the WK and G terminal prevents the gauge from working and may cause unintended shutdowns.
