Installation
• Gen Type is not 2-Wire Standby Mode – For all other Gen
Type settings (other than 2-Wire Standby mode), the generator
run sense must be 10 to 40 VDC—only while the generator
is running. The gen run sense voltage from the generator is
connected to Terminal 2 (positive) and Terminal 4 (negative)
on the green 8-port terminal block on the AGS; and can be a
switched B+ source from the generator, a positive signal from
the generator’s hour meter, or the generator’s running light.
To install the generator’s run sense voltage to the AGS:
1. Connect a wire (preferably not black or red) from the generator’s
run sense output to Terminal 2 on the 8-port terminal block.
2. Connect the negative terminal of the monitored battery bank to
Terminal 4 (power negative) on the 8-port terminal block. Ensure
the negative terminal on the generator battery is referenced/
connected to the negative terminal on the monitored battery.
Info: The negative terminal of the monitored battery bank
must be in common with the negative side of the gen run
sense signal from the generator. This ensures that the positive
battery voltage (to Terminal 3) and the positive gen run sense
voltage (to Terminal 2) have a common negative reference (to
Terminal 4), and are correctly sensed/measured by the AGS.
