Lovato Electric RGAM 12 is a microprocessor-based automatic transfer unit designed to manage and monitor stand-by generator sets
. It is specifically engineered to handle the automatic start-up of generators during mains power failure and supervise their operation. Core Functionality & Operating Modes
The RGAM 12 controller operates in four distinct modes, accessible via the front panel: OFF / RESET
: Disables the engine. If mains power is present, the load is switched to the mains. This mode is also used to reset active alarms. MAN (Manual)
: Allows the operator to manually start and stop the generator using the front-facing buttons. AUT (Automatic)
: The unit monitors the mains power; if an anomaly is detected, it automatically initiates the generator start-up cycle and transfers the load.
: Used to perform a controlled test of the generator set to ensure readiness without necessarily transferring the load. Technical Specifications Power Supply
: Dual-voltage compatibility for 12VDC or 24VDC battery systems. Monitoring
: Provides three-phase mains voltage control and single-phase generator voltage monitoring.
: Features a 3-digit display for readings (Voltage, Battery, Hours) and dedicated LEDs for engine status, glow plug pre-heating, and alarm states. Connectivity
: Includes an RS232/TTL port for quick setup via PC software and remote supervision. Common Alarm Codes
The unit monitors various engine and alternator parameters, displaying specific codes when a fault occurs: : Low oil pressure : Engine overheating : Failure to start (Match failure) : Low or high battery voltage : Emergency stop activated Manual & Documentation Resources

Lovato 31 RGAM 12 User Manual: Installation and Programming Guide
The Lovato 31 RGAM 12 is a specialized automatic control unit designed for engine-driven machinery, most commonly used in fire pump controllers and industrial generator sets. Known for its reliability and straightforward interface, this unit manages the starting, monitoring, and protection of diesel or gasoline engines. On a 12‑terminal (12T) model, terminals are numbered
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
Before installation, ensure your power supply and environment match the unit's requirements:
Supply Voltage: Usually 12VDC or 24VDC (dependent on the specific sub-model). Operating Temperature: -20°C to +60°C.
Protection Degree: IP54 (Front panel) when properly mounted with a gasket.
Inputs: Configurable inputs for oil pressure, water temperature, and fuel level. 2. Front Panel Layout
The interface is designed for quick diagnostics and manual override:
Display: A digital segment display showing battery voltage, engine hours, or error codes.
Mode Selector: Buttons for OFF, MANUAL, and AUTOMATIC modes.
Status LEDs: Indicators for "Engine Running," "General Alarm," and specific faults like Low Oil Pressure or Overheating. 3. Installation and Wiring
Proper wiring is critical to prevent "noise" from the alternator interfering with the control logic. Terminal Connections: Terminals 1-2: DC Power Supply (Check polarity carefully). Terminal 3: Fuel Solenoid output. Terminal 4: Starting Motor (Crank) output.
Terminals 5-8: Digital/Analog inputs for sensors (Oil pressure switch, temperature switch).
Terminal 11-12: Remote Start input (used for Automatic mode).
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
To enter the programming mode, you typically hold the OFF and MODE buttons simultaneously for 5 seconds. Common parameters include:
P01 (Crank Time): The duration the starter motor engages (default is usually 5s).
P02 (Number of Start Attempts): How many times the unit tries to start the engine before locking out with a "Fail to Start" alarm.
P03 (Cooling Time): Duration the engine runs without load before shutting down.
P04 (Oil Pressure Delay): The time allowed for oil pressure to rise after starting before the alarm becomes active. 5. Troubleshooting Common Faults
If your Lovato 31 RGAM 12 displays an error, refer to these common codes:
A01 (Low Oil Pressure): Check oil levels and the pressure sender unit. A02 (High Temperature): Check coolant levels and fan belts.
A03 (Over-speed): The engine RPM has exceeded the safety threshold; check the governor settings.
A04 (Start Failure): The engine failed to fire after the programmed number of attempts. Check fuel lines and battery health. 6. Maintenance and Safety
The RGAM 12 is a "set and forget" device, but the following maintenance is recommended:
Tighten Terminals: Vibrations from the engine can loosen screw terminals over time.
Battery Voltage: Ensure the battery charger is functioning, as low voltage can cause the RGAM 12 to reboot during the cranking cycle.
Disclaimer: This article serves as a general overview. Always consult the physical printed manual provided by Lovato Electric for specific wiring diagrams and safety warnings relevant to your hardware revision.

The 31 RGAM 12 is an older model; manufacturers often recommend the newer RGK800 series as a modern replacement for existing installations. Control unit for generating sets RGAM series
Lovato 31 RGAM 12 is a microprocessor-based automatic transfer and control unit designed for 12VDC stand-by generating sets. It manages the automatic starting of a generator during mains power failure and controls the changeover between mains and generator power sources. Амитрон-ЭК 1. Core Operating Modes
The unit features four primary operating modes, selectable via the front panel keys: OFF / RESET
: Disables the generator and inhibits control inputs. If the engine is running, selecting this mode stops it immediately without a cooldown period. It is also used to reset persistent alarms. MANUAL (MAN) : Allows direct control of the engine and load. Use the keys to manage the engine, and the (Mains) and
(Generator) keys to manually switch the load between sources. AUTOMATIC (AUT)
: The unit monitors the mains voltage. If the voltage fails or goes out of preset limits, the unit automatically starts the generator and switches the load. It returns to mains power and stops the generator once stable utility power is restored.
: Used to verify generator operation. The engine starts immediately; however, the load only switches to the generator if the mains power actually fails during the test. 2. Front Panel & Interface
The interface provides real-time monitoring and status indication: 3-Digit Display
: Shows RMS readings for mains/generator voltage, frequency, battery voltage, and engine hours. LED Indicators L1-L2, L2-L3, L3-L1 : Indicate the presence of mains phases.
: Lights up when a valid start signal (from alternator or generator voltage) is detected. NET / GEN Contactors
: Yellow LEDs indicate which contactor is currently energized. 3. Common Alarm Codes
When a fault occurs, the display flashes an alarm code. Use the SELECT/RESET key to view or clear them: : Low oil pressure (immediate engine stop). : Engine overheating (immediate engine stop). : Failure to start after the preset number of attempts.
: Generator voltage failure (out of limits during operation). : Emergency stop (input contact opened). : Maintenance required (based on programmed engine hours). 4. Advanced Features & Configuration Maintenance Reset : To clear the maintenance alarm, put the unit in mode and hold the button for 5 seconds. Automatic Test Interval : You can program periodic self-tests. To adjust, hold SELECT/RESET to enable/disable or set the day interval. PC Connection : The unit includes an RS232 serial port
