The Lovato 31 RGAM 24 boasts an impressive array of features that make it a top-notch generator controller:
Indicates the generator engine has started, stabilized, and is producing clean voltage.
Check fuel levels, check fuel solenoid operation, inspect the glow plugs, and verify the battery voltage does not dip below 9V DC during cranking. 2. High Engine Temperature (A02)
Inhibits engine starting. Resets active, cleared faults. Use this mode during mechanical maintenance.
Accurate wiring is critical for the AMF logic to function without destroying the digital inputs.

Relay output to close the utility motorized switch or contactor.
Designed for front-door installation on power stacks, typically with a 144x144mm cutout. Events Log:
Three-phase mains control (70–624VAC) and single-phase generator control.
Programming the 31 RGAM 24 is done primarily through its front keypad. The manual details each programmable parameter, including mains thresholds, generator start delays, engine parameters, and alarm configurations. The programming is stored in non-volatile memory, meaning it is retained even if the unit loses power. The Lovato 31 RGAM 24 boasts an impressive
: Look for "text-searchable" PDFs; they offer higher clarity than low-resolution scans.
: Configurable for single-phase or three-phase systems, with an operating range of 70VAC to 624VAC at a rated frequency of 50Hz or 60Hz.
Comprehensive specifications and model variations are available in the Lovato RGAM Series Catalog .
Ensure the 24V battery charger keeps the system between 26.8V and 27.6V float charge. Low voltage causes controller resets during cranking. High Engine Temperature (A02) Inhibits engine starting
Once you have your high-quality PDF, pay close attention to these three critical sections to ensure safe operation:
Annually check and torque all screw terminals to counter the loosening effects of industrial engine vibration.
Sets the time the controller waits after mains failure before initiating the engine start sequence. This prevents unnecessary cycles during momentary voltage sags.
