Lovato 31 Rgam 12 User - Manual

Remote Start input (used for Automatic mode).

Typically 12VDC (indicated by the "12" in the model name). Mains Voltage Input: 100–480VAC. Operating Temperature: -20°C to +60°C.

Clean battery terminals to prevent voltage drops that cause controller resets during cranking. Are you wiring it to a single-phase or three-phase system? What brand of generator engine are you pairing it with?

Nominal 12VDC with an operational tolerance band between 6.2VDC and 16.5VDC . lovato 31 rgam 12 user manual

: 3-digit LED display for readings (Voltage, Hz, Battery, Operating Hours) and 16 status LEDs.

The standard operational mode. The controller continuously monitors the mains. It manages the start-to-stop cycle autonomously during a power outage. Remote Start input (used for Automatic mode)

Gives operators direct command of the engine. The start and stop keys bypass automated line sensing logic, which is crucial for maintenance routines.

Allows the operator to start and stop the engine manually using the "Start" and "Stop" buttons.

This is the standard operational state. The internal microprocessor continuously samples the phase angle between the voltage and current vectors. It computes the active and reactive power components, automatically selecting the most efficient combination of capacitor steps to reach the target set in P.01 . Manual Mode Operating Temperature: -20°C to +60°C

The engine RPM has exceeded the safety threshold; check the governor settings.

Adjust the engine idle speed until the frequency reads a stable 50Hz or 60Hz. 🧽 Maintenance and Routine Testing

: Single-phase voltage and frequency monitoring.

At the hospital, the generator’s hum steadied machines and kept monitors steady. A nurse, soaked from the commute, squeezed Marco’s shoulder without a word. He thought of the manual’s fingerprints and the invisible line that connected him to its previous owner: a technician long retired, a neighbor who’d once fixed a radio, someone who had left instructions that were more about respect than torque values.
