If the mains are healthy but the generator keeps running, check the sensing fuses or the voltage calibration in the settings.
Follow the terminal diagram provided on the side of the unit to connect the battery supply, mains inputs, generator inputs, and relay outputs.
This technical guide serves as a comprehensive operational framework for installers, operators, and maintenance technicians handling the Lovato 31 RGAM 12 controller Technical Specifications and Overview The hardware architecture of the 31 RGAM 12
Danger: Always disconnect all AC mains, generator outputs, and DC battery lines before touching any terminal connections. High voltage can cause severe injury or death.
Precision monitoring of both mains (utility) and generator power. lovato 31 rgam 12 user manual
The RGAM 12 is engineered for reliability and precision in industrial environments.
: The unit monitors the mains power; if an anomaly is detected, it automatically initiates the generator start-up cycle and transfers the load.
: 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)
This is the most referenced part of the manual. The Lovato 31 RGAM 12 uses screw terminals. If the mains are healthy but the generator
After verifying proper generator voltage and frequency stabilization, it signals the Automatic Transfer Switch (ATS) to drop the mains load contactor and engage the generator circuit breaker. 4. Test Mode
To access the internal settings (thresholds, timers, and delays), you must enter the programming mode. Common Adjustable Parameters:
The configurable parameters typically include:
The Lovato 31 RGAM 12 is maintenance-free under normal conditions. However, in harsh environments: High voltage can cause severe injury or death
In the world of industrial automation and motor control, having a reliable and easy-to-monitor overload relay is non-negotiable. The Lovato 31 RGAM 12 is a thermal overload relay designed to protect AC motors from damage caused by overheating, excessive current draw, phase loss, or prolonged starting times.
| Symptom | Possible cause | Action | |---------|----------------|--------| | Switch does not latch | Broken cam spring | Replace switch | | High contact resistance | Oxidized contacts | Operate switch several times under load (self-cleaning) | | Overheating | Loose terminal or overload | Tighten screw / reduce load | | Handle difficult to turn | Debris or misaligned shaft | Check handle coupling |
Supports external signals for automated testing. Installation and Mounting
No – the thermal elements are calibrated for AC sinusoidal current. For DC motors, use a DC-rated electronic overload relay.
: Parameters can be programmed directly via the front keypad or through a PC using the RGAM remote control software Interface and Indicators LED Display
