b. The generator set engine starter cranks for 8 seconds, rests for 15
seconds, and cranks another 8 seconds if the generator set control
has not verified the information it is monitoring. Depending on the
outcome of this sequence, either a shutdown fault message is issued
or normal standby operation resumes.

4.4 Manual Start Sequence (Local)
NOTICE
If the utility power supply to the generator set's utility powered battery
charger is interrupted, the battery can become discharged due to parasitic
loads and the generator set may not start when needed. Whenever utility
power is interrupted and the generator set is not in Standby mode for any
reason (fuel preservation, etc.), start and run the generator set for 2 hours
every 24 hour period when temperatures are above 50 °F (10 ° C), or every 9
hour period when temperatures are below 50 °F (10 °C).
The following steps will be executed when Manual Start is used at the local display:
1. If you do not want the ATS to transfer load to the generator set, open the
generator set mounted circuit breaker when doing a manual start.
2. From the Main screen, select the START key.
3. A second screen appears notifying the operator that Standby will be disabled.
Select the START key again to start the generator set.
