Starter Cool Down
Purpose The Starter Cool Down setting allows an interval to be set between start
attempts if the generator fails to start on the first attempt. This time period
allows the start motor to cool sufficiently before the XW Auto Generator
Start signals it to begin cranking again.
When to use This setting is automatically configured when a “Gen Type” is selected
for the generator. Customize the “Starter Cool Down” trigger on the
advice of the generator manufacturer or authorized service personnel.
Gen Cool Down
Purpose The Gen Cool Down setting allows an interval to be set between a
generator stop trigger occurring and the AGS actually stopping the
generator. This setting is used in XW system to unload the generator
before the AGS shuts it down. When a stop trigger occurs, the AGS enters
a Generator cool down state where it continues to run the generator for the
specified time period. At the same time the XW inverter/charger will
disconnect the generator when it detects the AGS in Generator Cool
Down, allowing the generator operate unloaded and cool down before it is
shut down.
This helps improves reliability of the generator by reducing temperature
peaking due to abrupt shut down of a loaded generator. It also reduces the
probability of the generator backfiring that typically happens when the
generator is abruptly shutdown while under heavy load. Gen Cool Down
applies to all stop triggers namely Stop V, Stop Load, Stop float, Stop
Absorb, Stop Load, and Manual Off.
When to use This setting is automatically configured when a “Gen Type” is selected
for the generator. Customize the “Gen Cool Down” trigger on the advice
of the generator manufacturer or authorized service personnel.
