3.2 Low Current Alarm Operation
The Low Current Alarm shares the LED indicator and the alarm relay contacts with the charger failure alarm.
The Low Current Alarm will trigger when there is no current driven from the unit for 20 seconds. The alarm will
clear when at least 0.25A is pulled from the unit. The Alarm LED will blink in the low current condition and will
remain solid for Charger Failure. The Low Current alarm can be disabled by switching the SW1 DIP switch to
the on position.
Disabling the Low Current Alarm will not affect the Charger Failure Alarm.
The Low Current Alarm and Charger Failure Alarm share the same set of Form C contacts. The contacts will
change state under either alarm condition.
3.3 Remote Shutdown Operation
The remote shutdown feature allows the user to check the battery without disconnecting it from the charger.
The remote shutdown terminals allow for a bipolar input, when a ±12-24VDC signal is applied to these
terminals, the charger output voltage will drop to approximately 10.5VDC (21VDC for 24V chargers).
