Relays Inside the AGS controller
Positive DC voltage input [pos. terminal from
monitored battery bank (8.5-70 VDC from the pos.
terminal of the monitored battery bank); neg.
side connected to Terminal #4]
Negative DC voltage input [neg. terminal from
monitored battery bank (pos. side connected to
Terminal 3), and neg. side of the run sense signal
(pos. side connected to Terminal 2)]
Positive run sense input (10-40 VDC only when generator
is running; neg. side is connected to Terminal #4)
Not required if Gen Type setting is 2-Wire Standby mode

Info: The term “3-wire” refers to the minimum number of
wires required to control the starter motor and to run the
generator (may need more than three wires).
2.6.4 Common Generator Wiring Diagrams
Common generator starting/run/stop circuits can be divided into
three major types: 2-wire control, 3-wire momentary control, or
3-wire maintain control. Refer to the following gen wiring diagrams.
