: For a deeper understanding, explore the technical aspects, such as the electronics involved, programming (if applicable), and how it integrates with other systems.
: Allows direct user control over starting and stopping. lovato 31 rgam 12 user manual
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.
: Indicate engine status ( ENGINE ON ), mains/generator status, and active alarms (e.g., "A04" for start failure). 5. Remote Supervision The unit can be managed via the PC-RGAM software . Connection : via RS232 or RS485 serial interfaces.
This comprehensive manual provides all the technical specifications, step-by-step installation instructions, and troubleshooting workflows you need to operate the Lovato 31 RGAM 12 safely and efficiently. 1. Product Overview and Key Features Never set the dial above the motor’s FLA
In Eastern European forums, users have noted some specific challenges:
The Lovato 31 RGAM 12 is maintenance-free under normal conditions. However, in harsh environments:
Three-phase L1-L2-L3 (with or without neutral) up to 480VAC. : Allows direct user control over starting and stopping
Precision monitoring of both mains (utility) and generator power.
The Lovato 31 RGAM/12 is a compact, DIN-rail–mountable electronic relay/monitor (voltage/phase/sequence protection) used to protect three-phase electrical installations from faults such as phase loss, phase sequence reversal, unbalanced voltages, and over/under voltage.
