1.3 LED Indicators
Power LED indicators are installed on the power panel side. The output status is shown in the table below:
Indicator Mark | LED | Normal | Abnormal | Cause of Abnor mality |
Power Running Indicator | Green | On | Off | Power failure (no AC input, AC input overvoltage or undervoltage), no module output. |
Protection Indicator |
Yellow |
Off |
On | Temperature warning (ambient temperature exceeds 65℃, over-temperature shutdown), sleep shutdown (only protection indicator is on during sleep shutdown, module does not report alarms). |
Fault Indicator | Red | Off | On | Output overvoltage shutdown, fan failure, over- temperature shutdown, no output due to internal module causes. |
1.4 Communication Function
The module uses RS485 communication or CAN communication (one of two options). Main monitoring information of the module includes:
1) Voltage and current adjustment functions: meet the requirements of battery equalizing and floating charge, and voltage adjustment;
2) Single module on/off control;
3) Alarm information:
Power failure: AC input overvoltage or undervoltage.;
Module protection: Temperature warning;
Module fault: Output overvoltage shutdown, fan failure, over-temperature shutdown, or other internal module causes leading to no output (modules in sleep shutdown state and power failure do not report module faults).
