Lovato 31 Rgam 12 User Manual

Active only in MAN mode; manually engages the starter motor or initiates the cool-down/stop path.

Customising parameters ensures the controller matches your specific generator specifications. Step-by-Step Programming Access Switch the unit into mode.

Connect the voltage measurement inputs to phases L2 and L3. Crucial Note: The current sensing phase (L1) must be different from the voltage sensing phases (L2-L3) to achieve the correct 90-degree phase shift detection. lovato 31 rgam 12 user manual

| Symptom | Possible Cause | Solution | |---------|----------------|----------| | Motor trips immediately on start | Current setting too low; short circuit; locked rotor | Increase dial to match FLA; check motor windings | | Motor runs, then trips after several minutes | Overload; high ambient temp; incorrect setting | Measure actual motor current with clamp meter; reduce load; clean cooling vents | | Relay will not reset | Thermal element still hot; manual/auto setting wrong; mechanical stuck | Wait 5 minutes; check reset lever; press stop button then reset | | Contactor won’t stay closed | NC contact (95-96) open even without trip | Test continuity; replace relay if internal contact failed | | No trip even when motor draws >12 A | Dial set too high; relay defective; phase loss not detected | Verify setting; test with current injection tool | | Auxiliary contact not working | Loose wiring; contact burned | Check screws; measure voltage at 97-98 during trip |

Without specific details from the Lovato 31 RGAM 12 user manual, this response provides a general framework for approaching such a document. For a more detailed and accurate guide, always refer to the official manual and manufacturer's resources. Active only in MAN mode; manually engages the

The Lovato 31 RGAM 12 meets global standards, making it suitable for export machinery and UL-listed panels.

This is the most referenced part of the manual. The Lovato 31 RGAM 12 uses screw terminals. Connect the voltage measurement inputs to phases L2 and L3

Once the time parameter expires, the unit sends a start signal to the generator starter motor.

Below is a for a typical Lovato RGAM 31A rotary cam switch. For the exact manual, I recommend checking Lovato’s official website or contacting their support.

Solution: Check individual step currents with a clamp meter. Replace blown fuses or defective capacitors.
