Xantrex Technology Automatic Generator manual Run Hold Time, Crank Time

Configuration

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.

Run Hold Time

Full name	Generator Run Signal Hold Time
Purpose	“Run Hold Time” specifies the length of time the generator run signal (or
	B+ or hour meter signal) must be active before the Auto Gen Start
	considers the generator to be running and cranking can be stopped.
	Some generators assert their run signal when they are being cranked, but
	before they have started. They also have varying delays from when
	cranking begins or ends to when the run signal is asserted or unasserted.
	The Run Hold Time is designed to accommodate these generators.
	Values	Default
	0.0s to 20.0s (increments of 0.5s)	0.5s
When to use	This setting is automatically configured when you select a “Gen Type” for
	your generator. You should manually set “Run Hold Time” if you need to
	customize your Gen Type on the advice of your generator manufacturer or
	authorized service personnel.
Crank Time
Purpose	“Crank Time” specifies the length of time the Start relay is engaged (and
	cranking the starter motor) for the first attempt to start the generator.
	Values	Default
	0s to 250s (increments of 1s)	30s
When to use	This setting is automatically configured when you select a “Gen Type” for
	your generator. You should manually set “Crank Time” if you need to

customize your Gen Type on the advice of your generator manufacturer or authorized service personnel.
