Lovato 31 Rgam 12 User Manual Jun 2026

Check battery voltage during cranking (must stay above 9.5V DC). Verify fuel solenoid valve actuation. Low Oil Pressure / High Engine Temperature Cause: Sensor failure or actual mechanical engine distress.

3-digit LED/LCD reading display for voltage, frequency, battery status, and operating hours.

Insert the controller from the front of the panel dashboard. Slide the provided side-mounting brackets into place and tighten the screws until the front rubber gasket is compressed firmly against the panel door to prevent dust ingress. 4. Terminal Wiring and Electrical Connections

: Features a programmable automatic test cycle to ensure the generator is operational during long standby periods.

The is a robust microprocessor-based control unit designed for the automatic management of standby generating sets. It is part of the RGAM series, tailored to offer reliable engine control, monitoring, and transfer switching between the main power supply and the generator. lovato 31 rgam 12 user manual

Ensure these match your local infrastructure.

Green LED illuminates when the alternator produces stable voltage and frequency.

. It is specifically engineered to handle the automatic start-up of generators during mains power failure and supervise their operation. Core Functionality & Operating Modes

: Indicate engine status ( ENGINE ON ), mains/generator status, and active alarms (e.g., "A04" for start failure). 5. Remote Supervision The unit can be managed via the PC-RGAM software . Connection : via RS232 or RS485 serial interfaces. Check battery voltage during cranking (must stay above 9

The user interface consists of status LEDs, a segmented display, and tactile control buttons. Understanding the Operating Modes

The RGAM 12 controller operates in four distinct modes, accessible via the front panel: OFF / RESET

Heavy-duty relays for fuel solenoid, starter motor, and changer switch control

Dedicated RS-232 serial port standard on the base model. glow plug pre-heating

For advanced configuration, the 31 RGAM 12 can be connected to a PC via a serial interface. The software allows users to save, modify, and upload configurations, as well as customize SMS messages if a modem is connected. 4. Operating Modes
