2.0 Installation
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.
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 nega-
tive terminal on the monitored battery.
2.5.2 Generator Run Sense Connection (Terminals 2
&
4)
A generator 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 generator is actually 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*
– If your generator is fully auto-
matic and can start, run, and stop using only two wires, you may be able to
use the 2-Wire Standby setting (see Gen Type settings under Section 3.1).
When using this setting, the gen run sense signal is communicated from
the inverter to the AGS thru the network cable. The AGS determines that
the generator is running when the inverter/charger communicates that
it is in a charge state (i.e., Charging, Bulk Charge, Absorb Charge, etc.).
*
Requires ME-AGS-N with revision 5.2 to use 2-Wire Standby mode.
When using the 2-Wire Standby setting (and the generator is autostarted
by the 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 – pre-
venting another starter crank command from the AGS.
• Gen Type is not 2-Wire Standby Mode
– For all other Gen Type set-
tings (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.
What if my generator does not have a gen run sense output?
If your
generator is not equipped with a generator run sense output (10 to 40 VDC -
only while the generator is running), review the alternative options as shown
in Figure 2-10 to provide this gen run sense voltage to the AGS.
To make power connections from the monitored battery bank to AGS:
1. Route and connect a wire (black) from the monitored battery bank’s
negative terminal to Terminal #4 on the 8-port terminal block.
2. Route and connect a wire (red) with a 5-amp in-line fuse from the moni-
tored battery bank’s positive terminal to Terminal #3.
