NOTICE
Cummins Power Generation recommends the installation of an air intake
shutoff device or a similar safety device to minimize the risk of overspeeding
where an engine will be operated in a combustible environment.
NOTICE
Long periods of idling (more than ten minutes) can damage an engine. Do
not idle the engine for excessively long periods.
Sequence of Operation
NOTICE
The following sequences are based on an approximate time duration. Your
generator set may vary slightly from the timing diagrams in this manual. All
referenced times are based on default control settings. The following
sequences are applicable to generator sets connected to an RA series
transfer switch.
Power Outage Sequence
The sequence of operation after a power outage (when the generator set is in
Auto Mode) is as follows:
1. In normal operation, the utility power is running to the transfer switch and
then to the building load, and the generator set is off.
2. The utility power turns off (power outage).
3. One second after the power outage, the transfer switch sends the
command to the generator set to start.
4. If the ambient temperature is below 20 °F (6.7 °C), the generator set will
idle at 800 rpm for up to 2 minutes to allow sufficient turbo lubrication.
• Idle time is linear from 2 minutes at -40 F (4 °C), or below to off at 20
°F (6.7 °C) or above.
