NOTE: The Low Battery Alarm ON and OFF points operate
on rate compensated
(Peukert) amp hours consumed. Once the
alarm is activated, the battery must be charged until Alarm OFF Set
Point is reached to turn the alarm off.
F12 LOW VOLTAGE ALARM THRESHOLD
F12 sets the voltage below which the Low Battery Alarm is activated.
But the voltage must remain below this set point for a full 15 seconds
before the Low Battery Alarm goes ON. Dropping below the Low
Voltage Alarm Threshold for less than a full 15 seconds will not
activate the alarm.
If low voltage activates the alarm while the battery is above the Alarm
OFF (amp hour) Set Point, the alarm goes OFF as soon as voltage
remains above the low voltage threshold for 15 seconds. If the battery
is below the Alarm OFF (amp hour) Set Point when low voltages
turn the Alarm ON, the alarm stays on until the battery is recharged to
above the Alarm OFF (amp hour) Set Point.
RANGE: 5.0–40 V (0–50 V Scaling) STEP: 0.1 V Default 10.5 V
RANGE: 5.0–80 V (0–100 V Scaling) STEP: 0.1 V Default 10.5 V
RANGE: 50–400 V (0–500 V Scaling) STEP: 1.0 V Default 105 V
THINGS TO REMEMBER:
1) The Low Battery Alarm may be activated by either a low Voltage OR
a low amp-hour condition.
2) There must be a 10% difference between the Low Battery Alarm ON
set point and Low Battery Alarm OFF (Recharge) Set Point.
3) Because Low Battery Alarm ON may be triggered by rated compen-
sated (Peukert) amp hours, you may see fewer amp hours removed in
the numeric display than expected. The more rapidly you have
discharged your battery, the more pronounced this variance will be.
