Using an AGS Module: Setup
Info: When using the Gen 100% SOC Start autostart feature, the generator autostarts
and runs until the battery bank has reached 100% SOC or the AGS’s SETUP: 04F Max
Gen Run Time setting is reached, whichever occurs fi rst. Ensure the charger never
leaves the Bulk/Absorption charge mode. This is done by ensuring the SETUP: 03D
Absorb Done selection is “SOC” and the setting is 100% (Absorb Done SOC = 100%),
and either setting the Max Gen Run Time setting to OFF or setting it long enough to
ensure the generator is able to run until the battery is fully charged. If the charger is
allowed to exit the Bulk/Absorption charge mode (i.e., go to Float/Silent), the battery
SOC may never reach 100%.
Info: The Gen 100% SOC Start setting uses information from the BMK’s METER: 05I
Days Since 100% SOC menu to determine how many days have passed since the battery
bank has not been charged to 100% SOC. A valid SOC number must be displayed under
the METER: 05A BMK SOC menu for the BMK’s METER: 05I Days Since 100% SOC menu
to accumulate and display days. Think’n, No Comm, or any BMK fault (i.e., Factory
Fault, Power-up Fault, or Unknown Fault ##) are not valid SOC numbers.
SETUP: 04J Gen 100% SOC Start Menu
This setting allows the AGS to autostart the generator at a pre-selected time of day—whenever a
set number of days have passed since the battery bank has been charged to 100% SOC.
Info: The optional Battery Monitor Kit (ME-BMK or ME-BMK-NS) must be installed and
enabled to use the Gen 100% SOC Start feature.
• Set Gen 100% SOC (Start Gen Days) – This menu sets the maximum number of days the
generator waits before autostarting and fully charging the battery bank to 100% SOC. If the
battery bank has not been fully charged to 100% SOC in this number of days, the AGS starts
the generator at a pre-set time of day.
Default setting: Start Gen Days = OFF
Range: OFF, 1-255 Days
Info: The Start Gen Days setting must be between 1-255 days in order to enable the
Gen 100% SOC Start feature.
• Set Gen 100% SOC (Start Time) – This menu sets the time of day the generator autostarts
once the Start Gen Days setting is met.
Range: 12:00AM-11:45PM (15 minute increments)
Why should I use the Gen 100% SOC Start feature? In installations that primarily use a
generator to charge the battery bank, the generator run time is usually limited in order to save
on fuel costs, which does not allow the battery bank to be fully charged. If this situation persists
(where the batteries never reach full charge), some reduction in the battery life will occur. This
feature helps to maximize the life of the batteries.
How many days should I wait to fully charge my battery bank? Most battery manufacturers
recommend that the batteries be fully charged each time to ensure maximize battery life. With
this in mind, select the amount of days that gives you a good balance between reducing fuel
consumption and maximizing battery life. If the batteries are discharged heavily each day, then a
full charge would need to occur more often—maybe every 3-4 days. If the batteries are discharged
lightly each day, then a full charge may only be needed once every week or two. Monitor your
battery system to adjust the days to fi nd the best compromise.
How does the Gen 100% SOC Start feature work? This feature allows the generator to
autostart at a pre-selected time of day if the battery hasn’t been charged to 100% SOC (per the
ME-BMK battery monitor) for a set number of days. Once this feature is enabled (by setting Start
Gen Days value), the generator will start only after two conditions are met. First, the battery
hasn’t been charged to 100% SOC for a set number of days. This is determined by monitoring the
BMK’s METER: 05I Days Since 100% SOC value, which must be equal to or greater than the Start
Gen Days setting. Second, the 100% SOC start time of day (i.e., Start Time setting) must occur.
