Cummins does not know how you will use your generator set. The equipment owner
and operator, therefore, is responsible for safe operation in the installation site
environment. Consult your authorized Cummins service provider for further
information.
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 a single phase RA
series transfer switch.
Auto Start Sequence (with an RA Series Transfer Switch)
NOTICE
Standby Mode must be enabled for Auto Start to execute.
In normal operation, utility power is provided through the transfer switch to the
building loads; the generator set is not running.
FIGURE 17. GENSET STOPPED
If utility power is not available (that is, there is a power outage), the following
sequence will be executed to connect building load to the generator set, and
then reconnect building load back to the utility power when it is available.
1. The generator set starts.
