Battery On Discharge Alarms

Step

Action

1

Change BD alarm to 2 volts below float voltage (MENU > CONFIGURATION >
FLOAT SETTINGS > VOLTAGE ALARMS > BD).

2

Adjust the load to 50 amperes.

3

Verify the BD alarm occurs when the system voltage decreases to BD threshold.

4

Verify the BD alarm clears once the voltage has exceeded 0.5V above the BD alarm
threshold.

5

Restore the BD alarm threshold to its previous setting.

High Voltage Alarms
