Operation
03 BM: Meters
- This menu shows DC voltage, DC current and AH information
on the battery bank provided by the Battery Meter. The values for these
meter displays are updated each second.
Figure 5-2, METER: 03 BM: Meters Selections
DC Volts
- This meter displays the real-time battery voltage from 07.00
to 70.00 volts (± 0.02 volts).
DC Amps
- This meter displays the real-time charge current (amps into
the battery) or discharge current (amps out of the battery). Charging is
shown as a positive (+) number and discharging is shown as a negative (-)
number. The range is from ±0.1 to 999 amps, with a 1.0% accuracy.
AH I/O
- Amp-Hours In/Out; this meter displays the Ampere-Hours
returned to or removed from the battery. When this value is positive, it
represents amp-hours returned to the battery during any subsequent
charging. A negative value represents amp-hours removed from a full
battery. The range is ±32768 AH.
When using the
Chg Eff: Auto
setting, the AH I/O value is recalculated after
the battery has been fully charged (reaching 100% State Of Charge) and
≥
0.5% of the battery capacity has been discharged. If the Sense Module is
disconnected from power, the AH I/O displayed value resets to zero.
Info:
The AH I/O display correlates with the
03 Batt AmpHr
setting
(under the SETUP button) to help determine the 02 BM: SOC display.
Info:
AH I/O example; if you run a 10 amp load for three hours, the
display will show -30 AH. When you begin charging, the display will
count from -30 AH back toward 0 AH.
rAH Out
- Resettable Amp-Hours Removed; this meter displays the total
amp-hours removed from the battery since it was last reset. This display can
be used as a battery load indicator; to help determine and monitor the battery
load consumption. The range is 0 to 65,535.0 amp-hours (0.1 amp-hour
resolution).
To reset the AmpHrs value to zero, press and hold the rotary “SELECT” knob
for more than 5 seconds when this display is shown. After this display has
been reset, the display will begin calculating and displaying new ‘rAH Out’
values. This display automatically resets to zero if the Sense Module is
disconnected from power.
tAH Out
- Total Amp-Hours Removed; this meter displays the total amp-
hours removed from the battery since the Sense Module was
fi
rst connected.
This display can help be used as a battery service life indicator. The value
is displayed in 0.1k [or 100 amp-hours (“k” equals 1000)] resolution up to
a maximum of 6,553.5k amp-hours (6,553,500 amp-hours). The displayed
number resets to 0.0k when the Sense Module is disconnected from power.
