Xantrex Technology Automatic Generator - Manual (Page 80)

Configuration
3–32 975-0082-01-01
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.
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

cranking the starter motor) for the first attempt to start the generator.
When to use This setting is automatically configured when you select a “Gen Type” for
