Xantrex Technology XW manual Starter Cool Down, Gen Cool Down

The XW Auto Gen Start Menu

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.
	Values	Default
	1s to 250s (increments of 1s)	60s
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.
	Values	Default
	1s to 90s (increments of 1s)	30s
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.
