Meters
When not being actively configured, the Battery Monitor is operating in display
mode. By default, it displays the main battery voltage readout. To display one of
the other meters:
• Press the OK button repeatedly until the desired indicator illuminates.
• The LCD display will indicate the values for the currently selected function.
All readout selections can be navigated by using the < and > keys.
The standard readout selection sequence is as follows:
V (battery voltage) > A (charge/discharge current) > Ah (Amount of consumed
Amp-hours) > % (State-of-charge (SOC) > h (Time remaining until a battery
recharge is necessary) > °C (Battery temperature, or temperature setting if BTS
is installed) > V (Mid Point Voltage, if configured).
Available Meters
V (Volts) When this indicator is displayed, the LCD display shows the voltage currently
present at the battery. The range is 0 to 70 Volts. The accuracy is ±0.3%.
A (Amps) When this indicator is displayed, the LCD display shows the currently occurring
charge or load current in amps. The range is from ±0.1 to ±9999 amps with a
refresh rate of one second. The accuracy is ±0.4%.
Ah (Amp-hours) When this indicator is displayed, the LCD display shows the total amp-hours
used since the last time the amp-hour meter was reset. The range is from ±0.00
to ±9990 amp-hours. When the decimal point flashes, it means that more than
10,000 amp-hours have accumulated. In this case, multiply the reading by 1000
(i.e., 111 = 111,000). This meter automatically resets to zero approximately one
minute after the Full LCD stops flashing.
% (State-of-
charge)
When this indicator is displayed, the LCD display shows the battery’s State-of-
charge based upon the amp-hour reading divided by the amp-hour capacity of
the batteries (or battery bank). The values displayed are:
• Lo (when battery is below 27.5%)
• 30 to 90% numerical value (in 5% increments)
• Full (when the battery’s State-of-charge is over 92.5% capacity)
h (Time Remaining) Time remaining until recharge. Limit represented in HH:mm remaining time.
This readout displays “-----” when charging.
°C (Battery Temp) Battery temperature. Indicates the battery temperature if the Battery Temperature
Sensor (BTS) is installed. Otherwise, this will display the temperature as set in
Function F1.4.
V (AUX Volts) Displays the mid-point voltages Va1 and Va2 when mid-point voltage sensing is
used. When selected, this setting will alternate between displaying Va1 and Va2.
See “Mid-point sensing configurations” on page 3–35 for more information.
