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

Option 2 - Use a 120VAC to 12VDC step -down transformer (normally used to charge power
equipment batteries ) and plug into the generator’s 120VAC output. The step-down
transformer provides 12 VDC output only while the generator is running .

What if my generator does not have a run sense output? If your gen-
erator is not equipped with a generator run sense output, review Figure 2-6
for alternative options.
