How the InfraStruXure Power Generation System Operates
InfraStruXure Power Generation System 7
Generator start sequence
The generator start sequence is followed only if the Crank setting in the Operating Settings menu
on the Generator Settings screen on the ATS display interface is set to Yes. If enabled, the following
sequence will occur:
After a start signal is initiated, either by the ATS or manually, and the generator battery is good, the
generator engine will crank and the generator should start. If the generator does not start, it will crank
for the length of the Crank Time, and then rest for the length of the Rest Time. The generator will
repeat this pattern for the number of times set in Crank Cycles before discontinuing further attempts
to start. Check the messages on the display interface for reasons why the generator did not start.
On the generator controller interface, the LEDs track conditions during the start sequence:
Generator cool-down
After the generator has finished powering the load and utility power has been restored, the generator
will enter a 60-second cool-down period. NOTE: This 60-second cool-down period is a
recommendation from the generator manufacturer. The specified 60-second
cool-down period can
only be re-adjusted (at the ATS) by an APC service technician.
