Using an AGS Module: Setup
SETUP: 04K Gen 100% SOC Start Days
This menu allows the AGS to autostart the generator at a pre-selected time of day and to charge
the battery bank to 100% SOC—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 Days feature.
• Set Gen 100% SOC Start Days – This menu sets the maximum number of days the genera-
tor 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: OFF
Range: OFF, 1-255
Info: The Set Gen Exercise Days setting must be between 1-255 days in order to
enable the Gen 100% SOC Start Days feature.
◊ Set 100% SOC Run Hour – Set the hour the generator will autostart (once the Gen
100% SOC Start Days setting has been satisfi ed).
◊ Set 100% SOC Run Minute – Set the minute the generator will autostart.
◊ Set 100% SOC Run AM-PM – Set the time period (AM or PM) when the generator au-
tostarts.
Range: 12:00AM-11:45PM (15 min intervals)
Why should I use the Gen 100% SOC Start Days 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 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 manufactur-
ers recommend that the batteries be fully charged each time to ensure maximize battery life.
With this in mind, select the amount of days that provides 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 dis-
charged 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 Days 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
the Gen 100% SOC Start Days value to ON), 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 deter-
mined by monitoring the BMK’s METER: 05J Days Since 100% SOC value, which must be equal
to or greater than the Gen 100% SOC Start Days setting. Second, the Set 100% SOC Run start
time parameters (i.e., Hour, Minute, AM/PM settings) must have been satisfied.
Info: When using the Gen 100% SOC Start Days 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% (Set Absorb Done SOC =
100%), and either setting the 04F 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%.
