Installation
To connect the monitored battery bank to the AGS:
1. Route and connect a wire (black) from the monitored battery
bank’s negative terminal to Terminal 4 on the AGS.
2. Route and connect a wire (red) with a 5-amp in-line fuse from
the monitored battery bank’s positive terminal to Terminal 3.
2.6.2 Generator Run Sense Connection (Terminals 2 & 4)
A gen run sense signal/voltage is required as it alerts the AGS that
the generator is running; which prevents another starter crank to
the generator. If the gen run sense signal is not provided to the
AGS, the AGS commands the generator to autostop (in case the gen
is running), and then attempts another autostart sequence (up to
four start attempts before a gen start fault occurs). The Gen Type
switch setting (under Section 3.1) determines the required gen run
sense signal/voltage that must be provided to the AGS.
• Gen Type is 2-Wire Standby Mode* – A fully automatic
generator (can start, run and stop using only two wires) may be
able to use the 2-Wire Standby setting (see Gen Type settings
in Section 3.1). When using this setting, the gen run sense
signal is communicated from the inverter to the AGS through
the network cable. The AGS determines that the generator is
running when the inverter/charger communicates that it is in a
charge state (e.g., Charging, Bulk Charge, Absorb Charge).
When using the 2-Wire Standby setting (and generator is
autostarted by AGS), the generator runs and connects to the
input of the inverter. This causes the inverter to begin charging,
which in turn communicates to the AGS (via the network cable)
that the generator is running—preventing another starter crank.
* Requires ME-AGS-N with Rev
5.2 to use 2-Wire Standby mode.
Info: The AGS requires a DC input of 8.5 to 70 volts in order
to operate the internal relays (>70 volts causes damage to
the AGS and is not covered by the product warranty).
2.6.1 Power Connections (Terminals 3 & 4)
Terminal 3 (+) and Terminal 4 (–) on the 8-port terminal block are
connected to the monitored battery bank*. These terminals power
the AGS controller and monitor the inverter’s battery voltage (when
used to autostart the generator based on low battery voltage).
* Monitored Battery Bank – When autostarting the generator based on
battery voltage (e.g., start volts), the inverter’s battery bank must be
connected to Terminal 3 (+) and Terminal 4 (–). If autostarting based
on any other condition (e.g., temperature, amps), either the inverter
battery bank or the generator’s battery may be used to power the AGS
controller. However, the negative terminal of every battery bank must
be connected together to prevent damage to the AGS (refer back to
Section 2.5.1.1).
