Relay Configuration - Alarm Trigger

Low Voltage

The battery cell voltage is too low, resulting in a warning or fault.

High Voltage

The battery cell voltage is too high, resulting in a warning or fault.

High Charge Current

The charge current is too high, resulting in a warning or fault.

High Discharge Current

The discharge current is too high, resulting in a warning or fault.

Low Temp Charge

The battery temperature is too low to charge, resulting in a warning or fault.

Low Temp Discharge

The battery temperature is too low to discharge, resulting in a warning or fault.

High Temp Charge/Discharge

The battery temperature is too high to charge/discharge, resulting in a warning or fault.

High Board/Relay Temp

The board/relay temperature is too high, resulting in a warning or fault.

Hardware Diagnostics

Battery Management System hardware fault. This may indicate issues with the voltage or current sensors, hardware clock, relays, or a load qualification error.

Breaker Open

The breaker is open on the battery. AES RACKMOUNT, AES 210HV, and AES Battery Cabinet only.

E-Stop

The E-stop button has been activated. AES 210HV and AES Battery Cabinet only.

Maintenance
