Using a BMK: Operation/Monitoring
8.2.2 BMK METER Menu Items (with ME-RTR)
From the BMK Home screen, press the METER button, and then turn the SELECT knob on the ME-
RTR router to access the different meters that determine the status of the battery system.
Info: If multiple BMKs are connected, the System Home screen displays information
from the BMK connected to the LOWEST numbered port. For example, if a BMK is
connected to the network port on an inverter which is connected to Port 1 (P1Acc), and
another BMK is connected to Port 5 on the router (P5), the System Home screen will
show the information from the BMK connected to P1Acc.
METER: 05A BMK SOC
This read only menu either displays the calculated battery SOC (State of Charge) for the connected
battery bank, “Think’n” (to indicate the SOC is being calculated), or identifi es a fault condition.
Note: Refer to Section 8.2.4 for information on BMK statuses/faults.
The range is 0% to 100%, where 100% is a fully charged battery and at 0% the battery is completely
discharged. When the BMK sense module is fi rst connected, the display will show “Think’n”, to
indicate that the SOC reference point is being calculated. After the batteries are fully charged, the
display will change from “Think’n” to “100%” and begin to provide accurate SOC percentage values.
Note: If the sense module is disconnected from power, this display resets to “Think’n” and the
batteries require another full charge before this display begins providing SOC percentage information.
METER: 05B DC Volts-BMK
This meter displays the DC volts at the BMK input. The range is from 07.00 to 70.00 volts (± 0.02).
METER: 05C DC Amps-BMK
This meter displays the real-time charge current (amps into battery) or discharge current (amps
out of battery) as measured through the BMK shunt. Charging is shown as a positive (+) number
and discharging is shown as a negative (–) number. The range is from ±0.1 to 999 amps (±1.0%).
METER: 05D Amp Hours In/Out
This meter displays the AHrs returned to or removed from the battery. When this value is positive,
it represents AHrs returned to the battery during any subsequent charging. A negative value
represents AHrs removed from a full battery. The range is ±32,768 AHrs. When using the charge
effi ciency’s Auto setting, the AH I/O value is recalculated after the battery has been fully charged
(100% SOC) and ≥0.5% of the battery capacity has been discharged. If the sense module is
disconnected from power, the displayed AH I/O value resets to zero.
Info: The Amp Hours In/Out display correlates with the SETUP: 05B AmpHrs Size
setting to determine the 05A BMK SOC display. Example: running a 10-amp load for
three hours, the display shows “-30 AH”. When you begin charging, the display will
count from – 30 AHrs back toward 0 AHrs.
METER: 05E Resettable AHrs
This meter displays the total AHrs removed from the battery since the sense module was fi rst
connected or since last reset. This display can be used as a battery load indicator to help identify and
monitor the battery load consumption. The range is 0 to 65,535.0 AHrs (0.1 amp-hour resolution).
To reset the AHrs value to 0.0, either disconnect the sense module from power, or press and hold
the rotary SELECT knob for ~2 seconds when this display is shown. After this display has been
reset, it will begin calculating and displaying new rAH out values.
METER: 05F Total kAHrs Out
This meter displays the total AHrs removed from the battery since the sense module was fi rst
connected or since it was last reset. This display can be used as a battery service life indicator.
The value is displayed in 0.1k [or 100 AHrs (“k” equals 1000)] resolution up to a maximum of
6,553.5k AHrs (6,553,500 AHrs).
To reset the kAHrs value to 0.0, either disconnect the sense module from power, or press and hold
the rotary SELECT knob for ~2 seconds when this display is shown. After this display has been
reset, it will begin calculating and displaying new kAHrs out values.
