If your unit is flashing a code, here are the most frequent ones found in the Lovato RGAM Guide Low Oil Pressure Engine Overheating Low Fuel Level lovato 31 rgam 12 user manual
The is a microprocessor-based Automatic Mains Failure (AMF) control unit engineered by Lovato Electric to automatically manage stand-by generating sets . Operating on a 12VDC auxiliary power supply , this standard 144x144mm panel-mount controller continuously monitors three-phase utility lines and safely transfers power to a single-phase generator when mains anomalies or outages occur.
Setting the "Low Voltage" limit (e.g., 180V on a 230V system) that triggers a start. 6. Troubleshooting Common Issues
Use an infrared camera to check for hot spots on the Lovato controller terminals and capacitor contactors. The unit monitors critical engine and alternator functions,
This guide provides a comprehensive overview of the setup, wiring, and operational parameters found in the Lovato 31 RGAM 12 user manual. 1. Technical Specifications
Most users set these relays for "Under voltage" only, but the manual describes a more protective "Window Mode."
Usually 12VDC or 24VDC (dependent on the specific sub-model). Operating Temperature: -20°C to +60°C. A05/A06 : Battery voltage anomalies (low/high)
The controller senses that utility voltage has dropped below the on any phase for longer than a pre-set delay timer (typically 3–5 seconds). Phase 2: Engine Startup
The time the controller waits after utility power returns to ensure grid stability before transferring the load back (adjustable from 1 to 5 minutes).
Connects to the engine's fuel valve or electronic governor system.
