The Harsen GU641B is an Automatic Mains Failure module for a genset, not a car. The alarm issues mentioned in the manual include:

- Coolant Pre-Alarm: Triggered by high engine temperature, based on the HET sensor.
- Coolant Alarm: Activated for high engine temperature, also using the HET sensor.
- Battery Undervoltage Pre-Alarm: Indicates low battery voltage.
- Battery Overvoltage Pre-Alarm: Indicates high battery voltage.

These alarms help monitor and protect the genset engine.
