The default setting for standby power. The unit monitors the mains and will automatically initiate the start sequence if power fails.
Selecting Test Mode mimics a mains blackout without dropping the active live utility feed to the building. The controller starts the engine and stabilizes generator parameters to verify overall system health. Depending on configuration, it runs either as a dry, non-load test or a true emergency load transition exercise. Wiring and Electrical Connections

Proper installation is critical for the safety of the controller and the operator. Use a standard 138x138mm square opening. Fixing: Secure with the provided side slide-on clips.
The RGAM 12 is part of Lovato Electric’s legacy series of controllers. It is engineered to monitor a single-phase or three-phase mains supply and automatically start a generator if the mains voltage falls outside of preset limits. Once the generator is running and stable, the RGAM 12 manages the transfer of the load from the mains to the generator. Key Features: The default setting for standby power
Based on the model number , you are likely referring to the LOVATO Electric DMB series (often marked as DMB31 or similar) or the RPGM/DMG series of electronic voltage monitoring relays.
Stores running hours and maintenance data even during power loss.

The Lovato 31 RGAM 12 acts as the brain of a generator system. Its primary role is to monitor the mains electricity (single or three-phase) and, in the event of a failure, start the generator and transfer the load. Key Features of the 31 RGAM 12:
