Lovato 31 RGAM 12 User Manual: Complete Guide to Installation, Configuration, and Troubleshooting

Product Code: 31 RGAM 12 Manufacturer: Lovato Electric

1. Overview

The Lovato RGAM series is a family of heavy‑duty rotary cam switches designed for industrial and commercial electrical applications. They are modular, compact, and rated up to 31A (depending on model). The switch you reference — RGAM 31 12 — is likely a 31A, 12‑terminal device used for changeover (transfer) or selector functions.

Q1: Can the Lovato 31 RGAM 12 be used with single-phase motors?

A: Yes, but only for overcurrent protection. Pass the live wire through all three phases in series (L1 and L2 paralleled, L3 unused). Phase loss sensitivity will be disabled. Consult the manual for wiring.

B. RGAM 12 – Two-pole changeover (3-position)

The Lovato 31 RGAM 12 (often part of the wider RGAM series) is a microprocessor-based control unit designed for the automatic management and starting of stand-by generating sets. lovato 31 rgam 12 user manual

Below is a draft of the core technical and operational sections typically found in its user manual. 1. General Overview

The unit monitors the mains power supply and automatically starts the generator during anomalies (undervoltage, overvoltage, or asymmetry). It provides: Mains Control: Single or three-phase monitoring.

Generator Control: Single-phase voltage and frequency monitoring.

Microprocessor Control: Programmable parameters and event logging (up to 255 events). 2. Technical Specifications Feature Supply Voltage ( Uscap U sub s ) 12VDC or 24VDC (nominal) Operating Range (12V) 6.2 – 16.5VDC Operating Range (24V) 13 – 33VDC Mains Voltage Range 70 – 624VAC Rated Frequency 50 or 60Hz (keypad configurable) Tripping Adjustments Min: 0.7-1 Uecap U sub e ; Max: 1-1.2 Uecap U sub e 3. Operating Modes The controller features four primary operational states: OFF: The unit is disabled; no automatic actions occur.

MAN (Manual): Start or stop the generator manually using the START and STOP buttons. Lovato 31 RGAM 12 User Manual: Complete Guide

AUT (Automatic): Automatically starts the generator if the mains fail and switches back once power is restored.

TEST: Simulates a mains failure to verify generator readiness without necessarily switching the load. 4. Front Panel Interface

3-Digit LED Display: Shows readings such as battery voltage, generator frequency, and line-to-line mains voltage.

SELECT/RESET Button: Toggles between displayed values (MAINS, GEN, FREQ, BATT, HOUR) or clears active alarms.

Status LEDs: 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. Angular throw : 60° (0° – 60° –

Capabilities: Real-time monitoring of status, alarm history viewing, and editing of setup parameters.
