Operational Fault
Faulty battery
Possible Cause: The device has detected a short-circuit on the connected battery or that it has completely exhausted its capacity.
The device isolates the damaged battery and signals the anomaly with long blinks on the corresponding LED on the BDS180 and on the MC-180 control panel. The batteries can be reset manually by turning the device off and on again.DIY Safe
Operational Fault
Battery protection function activated
Possible Cause: The battery voltage dropped below 9.5V.
The battery protection function disconnects all users when the voltage drops below 9.5V to avoid irreversible damage. If the voltage does not rise above 9.5V, the power supply is guaranteed for up to 1 minute; if it drops below 8.5V, the device turns off automatically. The batteries can be reset manually by turning the device off and on again.DIY Safe
