10.0 Using the ME-RTR Router
Where should I set Gen Run SOC? Most battery manufacturers recom-
mend that for optimum battery life, deep-cycle batteries should not be dis-
charged below 50% SOC. The ME-BMK determines the battery’s SOC by
using a DC shunt to measure the fl ow of current in and out of the battery.
Many refer to a SOC meter as a “fuel gauge” for your batteries, since this
meter gives you an accurate reading of how much capacity is remaining in
the battery bank.
Set the Start Gen SOC level to 50%, or to 60% if you do not want to dis-
charge the batteries quite as much. When considering the Stop Gen SOC
setting, keep in mind that running the generator past 90% SOC delivers
very little current to get that last 10% into the batteries. Thus, it is common
to stop the generator at 90% to save fuel and run time on the generator.
However, if the SOC stop setting is less than 100%, the batteries should be
charged to 100% as often as possible (~ once per week, or every other dis-
charge cycle) in order to avoid sulfation of the battery plates.
SETUP: 04E Gen Run Temp Menu
This menu allows you to set and enable a temperature value that will auto-
matically start the generator — typically, to power an air conditioner unit for
cooling — based on an increase in temperature, or by using an A/C thermo-
stat control.
Info: The optional ME-PT1 or ME-PT2 pigtail adapters can be used
to connect an A/C or relay control circuit. For more info, refer to the
instruction sheet for each pigtail adapter (part number 64-0025 for
ME-PT1 instructions, or 64-0026 for ME-PT2 instructions).
Info: This temperature autostart feature requires that the AGS’s re-
mote temp sensor cable (Figure 1-2) or an optional ME-PT1 or ME-PT2
pigtail adapter be connected to the AGS’s REMOTE port (Figure 2-3).
When using the remote temperature sensor, its location determines
the area being monitored for temperature.
• Set Gen Run Temp Start – This menu is used to enable and set the
temperature that triggers a generator autostart.
65F - 95F (18C - 35C) – These settings determine the rising tempera-
ture value that triggers a generator temperature autostart.
Ext Input – This setting is used when an optional pigtail adapter (ME-
PT1, or ME-PT2) is used. When an AGS pigtail adapter is connected to
the AGS’s REMOTE port, an external command — either from a ther-
mostat connection on an air conditioner control circuit or external relay
control circuit — is recognized and causes the generator to start.
Default setting: Set Gen Run Temp Start = OFF
Range: OFF, Ext Input, 65F - 95F or 18C - 35C (5 deg. increments)
Info: If the temperature start feature is not needed, ensure this
setting is set to the OFF position.
• Set Stop Gen SOC – This menu is used to set the SOC level for
autostopping the generator.
Default setting: Set Stop Gen SOC = 90%
Range: 21% - 100%
Info: There is no start or stop delay time needed since the ME-BMK
already displays an accurate state of charge of the batteries.
