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.
Stores running hours and maintenance data even during power loss.
: 12VDC nominal voltage (Typically mapped across an operating window of 9VDC to 16VDC). Physical Form Factor : 144mm x 144mm front-panel mount.
Always consult a qualified electrician or generator technician before modifying high-voltage control panels.
To adapt the 31 RGAM 12 to your specific engine and regional grid parameters, internal potentiometers or dip switches on the rear/side of the housing must be adjusted: lovato 31 rgam 12 user manual
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
Lovato 31 RGAM 12 User Manual: Installation and Programming Guide
Generator speed governor is poorly adjusted, or the alternator AVR is failing.
: Toggles between displayed values (MAINS, GEN, FREQ, BATT, HOUR) or clears active alarms. When a fault occurs, the display flashes an alarm code

To enter the programming mode, you typically hold the and MODE buttons simultaneously for 5 seconds. Common parameters include:
Features a 3-digit LED display for readings (voltage, frequency, battery, hours) and 16 status LEDs. Remote Monitoring:
| Parameter | Description | Typical Value | Why it matters | | :--- | :--- | :--- | :--- | | | Mains undervoltage threshold | 184V (for 230V nominal) | Prevents transfer when grid voltage sags. | | P03 | Mains return delay (Timer T1) | 60 seconds | Ensures the grid is stable before re-transfer. | | P05 | Generator starting delay (Timer T2) | 5 seconds | Gives the generator time to start before the controller tries to transfer. | | P07 | Generator stabilization delay (Timer T3) | 10 seconds | Allows generator voltage/frequency to stabilize. | | P10 | Generator stop delay (Timer T4) | 180 seconds | Cool-down period for the generator after load is removed. | | P15 | Remote test enable | 1 (Enabled) | Allows a remote switch to simulate a mains failure. | | P22 | Display language | English / Italian | Sets the LCD text language. | : Failure to start after the preset number of attempts
