Lovato 31 Rgam 12 User Manual !link! -

Based on the model number LOVATO 31 RGAM 12, you are likely referring to the LOVATO Electric DMB series (often marked as DMB31 or similar) or the RPGM/DMG series of electronic voltage monitoring relays.

4. How to Set the Current (9鈥�12 A Range)

The most critical part of using the Lovato 31 RGAM 12 user manual is correctly setting the overload current. An incorrect setting will either cause nuisance tripping or fail to protect the motor. lovato 31 rgam 12 user manual

Step 3: Control Wiring (Logic Inputs/Outputs)

• Generator Start (Relay K1): Connect a two-wire start signal from terminals 15-16 to the generator鈥檚 auto-start module. Use shielded cable if the run exceeds 10 meters.
• Transfer Commands: Connect terminals 18-19 (Load to Generator) and 20-21 (Load to Mains) to the coils of your changeover contactors or motorized switches.
• Emergency Stop: Wire a normally closed (NC) pushbutton between terminal 22 (Common) and terminal 24 (Emergency).

• Green LED: Supply voltage is present.
• Red/Yellow LED: usually indicates the relay has tripped (fault condition).
• Blinking Codes: The manual often lists specific blinking patterns that tell you if the fault was Over-Voltage, Under-Voltage, or Phase Loss, saving you diagnostic time.

AUT (Automatic): The standard operating mode. The device constantly monitors the mains and will take over automatically during a blackout. 5. Programming and Configuration Based on the model number LOVATO 31 RGAM

The Lovato 31 RGAM 12 is a microprocessor-controlled automatic transfer unit designed to manage stand-by generating sets. It primarily monitors mains power anomalies and automatically initiates a generator start-up cycle to ensure power continuity. 馃洜锔� Key Technical Specifications Generator Start (Relay K1): Connect a two-wire start

Generator Sensing: Connect the alternator output phases so the controller knows when the generator has reached the correct voltage and frequency. Control Outputs: Start: Connects to the starter motor relay. Fuel: Connects to the fuel stop-solenoid.
