This circuit failure will require manual reset, by switching off input power. The charger monitors the output current to make sure that there is a battery and load connected. This set point is field connected. A visual LED alarm is provided and the Alarm Relay is triggered. Alarm condition is automatically reset when the circuit senses the load.
False alarms can occur when there is a small load and the charger switches from equalize to float.
No current can flow from the charger creating the alarm condition. As the battery voltage decays to the float voltage the alarm goes away. Low-Voltage Load Disconnect. This feature disconnects the load to protect the battery from being over-discharged. The disconnect point is field adjustable.
