Alarm Type
Associated Alarm
Codes
How Alarm is Set
1. If the unit is not preheating or starting, and battery voltage is less than 11.2 volts for 3 minutes, Alarm Code
61 is set a as a Shutdown alarm.
2. If the preheat current prior to an engine start is below 10 volts during an engine start, Alarm Code 61 is set
as a Log alarm.
3. If during a Pretrip Test the preheat amps check is not within limits, and battery voltage is less than 11.3
volts, Alarm Code 61 is set as a Shutdown alarm.
4. If during a Pretrip Test all outputs are de-energized, and battery voltage is not within limits, Alarm Code 61 is
set as a Shutdown alarm.
5. If the unit is in Evacuation mode, and battery voltage is greater than 16.0 volts for 3 minutes, Alarm Code 61
is set as a Shutdown alarm
6. If the ambient temperature is more than 10.0°F from setpoint, or if the ambient sensor is failed and three
consecutive Cycle Sentry low battery restarts occur, Alarm Code 61 is set as a Log alarm.
7. If three power-up and start attempt are made, Alarm Code 61 is set as a Shutdown Alarm. This indicates
that the battery voltage dropped low enough during the start sequence that the microprocessor powered
down.
How Alarm is Cleared
This alarm is cleared manually.
Diagnostic Procedure
1. Check for discharged battery and charge as required.
2. Check the battery terminals for tightness and corrosion.
3. With the engine running, check the battery voltage using the Gauge Menu.
4. With the engine running, check the battery charge rate using the Gauge Menu.
