Installation
Option 3 – Use an external 120 VAC coiled relay to bring the
generator’s battery voltage to the AGS gen run sense terminal
(Terminal #2) only when the generator is running. The generator’s
battery voltage must be 10 to 40 VDC.

Option 2 – Use a 120 VAC to 12 VDC step-down transformer
(normally used to charge power equipment batteries) and plug
into the generator’s 120 VAC output. The step-down transformer
provides 12 VDC output only while the generator is running.
What if my generator does not have a gen run sense output?
Review the alternative options (Figure 2-10) to provide this gen run
sense voltage to the AGS.
Option 1 – Tap into the positive side of the generator’s hour meter
or running light; ensure the voltage is only 10-40 VDC while the
generator is running.
