Smart Distribution Panel with ATS 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 menu is set to Ye s. If it is 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 the Crank Cycles before
stopping the attempt 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 load is powered by the generator, and mains returns and is powering the load, the generator
may enter a cool-down period. If the coolant temperature is above the Coolant Temperature Limit,
the generator will enter a cool-down period. During generator cool-down, the generator disconnects
the alternator from the output and then runs at idle speed for 10 minutes. After the idle speed time
expires, the generator will shut down. If the coolant temperature is not above the Coolant
Temperature Limit, the generator will not enter a cool-down period but will shut down after mains
returns and is powering the load.
