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.
