Xantrex Technology XW manual Exercise Time, Relay3

Configuration

Exercise Time

Purpose	“Exercise Time” sets the time of day that the XW Auto Generator Start
	exercises the generator.
	The “Exercise Time” trigger requires that any parameter other than “0” be
	set in “Exercise Per” and a value be set in the “Exercise Dur” trigger.
	Values	Default
	12:00AM to 11:50PM (12-hour clock)	9:00AM
	00:00 to 23:50 (24-hour clock)
	(increments of 10 minutes)
Considerations	If the Exercise Time is set, the generator will start at that time after being
	inactive for the Exercise Period.
	If the Exercise Time occurs during Quiet Time, the generator will start
	when Quiet Time is over and run for the full amount of time set for
	“Exercise Dur”.
Relay3
Purpose	“Relay3” sets the function of Relay 3 of the XW Auto Generator Start.
	The function of Relay 3 affects contacts 19 and 20 of the 20-contact
	connector and external wiring harness.
	Values	Default
	NotUsed, Preheat, PreheatSDByp	NotUsed
Considerations	Selecting a value for “Gen Type” automatically configures “Relay3”.
	It might be necessary to manually set “Relay3” according to the make and
	type of generator being used.

Some diesel generators require preheating of their glow plugs before start cranking. Setting “Relay3” to Preheat enables Relay 3 to perform this function in addition to Relay 1.

Some generators require Relay 3 to switch 12 volts to the glow plugs, while some generators require ground to be switched to the glow plugs.

“PreheatSDByp” stands for Preheat with Shutdown Bypass. Some generators require preheat on relay 3 to remain high for crank time and shutdown bypass period. See “GlowStop Mode” on page C–4 for more details.
