Configuration of the Xanbus AGS

Relay3

Purpose "Relay3" sets the function of Relay 3 of the AGS. 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 84 for more details.

Gen Run Hold Time

Full name Generator Run Signal Hold Time

Purpose "Gen Run Hold Time" specifies the length of time the generator run signal (or B+ or hour meter signal) must be active before the AGS 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

 

 

Considerations This setting is automatically configured when a "Gen Type" is selected for the generator. Manually change this setting only on the advice of the generator manufacturer or authorized service personnel.

If the installation is made without a B+ connection, it might be necessary to adjust the Gen Run Hold Time for the AGS to successfully start the generator. When the B+ signal is not connected, the AGS requests generator status from the Inverter/Charger, which might take longer that if the B+ signal was connected.
