I was unable to locate a specific user manual for a model exactly matching “Lovato 31 RGAM 12” after searching my available resources.

Modifying Parameters: Use the MAINS/GEN keys to navigate menus and MEAS/TEST keys to select specific parameters.

Pro Tip: Always use a flyback diode on the starter and fuel solenoid relays to protect the internal circuitry of the RGAM 12 from voltage spikes. 4. Programming Parameters lovato 31 rgam 12 user manual

| Parameter | Description | Typical Value | Why it matters | | :--- | :--- | :--- | :--- | | P01 | Mains undervoltage threshold | 184V (for 230V nominal) | Prevents transfer when grid voltage sags. | | P03 | Mains return delay (Timer T1) | 60 seconds | Ensures the grid is stable before re-transfer. | | P05 | Generator starting delay (Timer T2) | 5 seconds | Gives the generator time to start before the controller tries to transfer. | | P07 | Generator stabilization delay (Timer T3) | 10 seconds | Allows generator voltage/frequency to stabilize. | | P10 | Generator stop delay (Timer T4) | 180 seconds | Cool-down period for the generator after load is removed. | | P15 | Remote test enable | 1 (Enabled) | Allows a remote switch to simulate a mains failure. | | P22 | Display language | English / Italian | Sets the LCD text language. |

Provides three-phase control for the mains (70–624VAC) and single-phase control for the generator. Operation Modes: Includes four distinct modes: (disabled), (manual start/stop), (automatic standby), and (periodic manual or automatic testing). Key Specifications & Features Power Supply: I was unable to locate a specific user

Power Supply: Operates on a 12VDC battery supply (range: 6.2–16.5VDC).

Voltage Monitoring: Tracks under-voltage and over-voltage conditions. | | P05 | Generator starting delay (Timer

Where to find the full manual

Search the exact model number and “user manual” or “installation sheet” on the manufacturer’s site or authorized distributor pages to get wiring diagrams, terminal assignments, detailed settings, and certification data.

Monitoring: It monitors three-phase mains voltage and single-phase generator voltage and frequency. It also tracks battery voltage, engine speed (RPM), oil pressure, temperature, and fuel levels.
