8.2.2 Monitoring the BMK using the ME-ARC
Use the ARC remote’s METER button to monitor battery bank information and to determine the
status of your battery system.
METER: 05 BMK Meters
This section describes what battery bank information is available from the battery monitor when
using the ARC remote.
• 05A
BMK Status – This menu selection offers read only displays that give the current operat-
ing status of the battery monitor. This selection also provides information to determine if there
is a power-up fault condition (see Table 8-1).
• 05B Battery 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%-100%, where 100% is a fully charged battery and 0% is completely dis-
charged. 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 changes from “Think’n” to “100%” and begins to provide accurate SOC% values.
Note: If the sense module is disconnected from power, this display resets to “Think’n” and the
batteries require another full charge before SOC percentage information is displayed.
• 05C 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)
• 05D DC Amps-BMK – This meter displays the real-time charge current (amps into battery)
or discharge current (amps out of the 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%).
• 05E AH In/Out – This meter displays the AH returned to or removed from the battery. When
this value is positive, it represents AH returned to the battery during any subsequent charging.
A negative value represents AH removed from a full battery. The range is ±32,768 AH. 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 AH I/O value resets to zero.
