UNDER-FREQUENCY Shutdown Alarm

Control Panel

Figure 1 – Generator Control Panel

After starting, if the generator stays under frequency for more than 30 seconds, it will shutdown.

MISSING CRANK PULSE ALARM

This is a shutdown alarm. The alarm will activate after 12 con- secutive revs where crank pulses are missing.

LOW BATTERY ALARM

While running if the average battery voltage falls below 11.9 volts for one (1) minute, the low battery alarm will be displayed.

LOW FUEL PRESSURE WARNING

Fuel pressure is monitored by a digital sensor with a fixed setpoint of below five (5) inches water column.

LOW BATTERY WARNING

The microprocessor will continually monitor the battery voltage and display the Low Battery Voltage message if the battery voltage falls below 12.2 Volts for one (1) minute.

No other action is taken on a low battery warning condition. The warning will automatically clear if the battery voltage rises above 12.2 volts.

NOTE:

The battery sentinel is a separate feature that monitors battery condition.

LOW COOLANT LEVEL ALARM

This is a shutdown alarm. The sensor will be continuously moni- tored. If an error condition is seen for five (5) consecutive sec- onds, the alarm will be displayed.

GOVERNOR SENSOR FAULT ALARM

The governor position is monitored by an analog feedback signal. If the throttle position is seen outside of the normal operating range, a shutdown alarm is displayed. If the throttle is commanded to move, and no movement is seen, a shutdown alarm is displayed.

WIRING ERROR ALARM

When power is first apllied to the contoller, the software will per- form a check on the wiring of the transfer output, and ensure it does not have high voltage on the wire. If this is the case, it will signal a miswire alarm and will not run. The test can be skipped by use of the escape key.

UNDERVOLTAGE ALARM

If the generator voltage falls below 60% for >5 seconds, an alarm will be issued.

MISSING CAM PULSE ALARM

This is a shutdown alarm. The alarm will activate after five (5) seconds of continuously missing cam pulses.
