Manual Mode: Allows operators to start or stop the engine directly using the Start and Stop keys on the front panel.

Test Mode: Permits scheduled or manual test cycles to verify generator readiness without necessarily transferring the load.

Off/Reset: Disables the unit's control functions and resets active alarms. Technical Specifications Power Supply Supports 12VDC or 24VDC battery systems. Voltage Control

Three-phase mains supervision and single-phase generator control (70–624VAC range). Display

3-digit LED/LCD reading display for voltage, frequency, battery status, and operating hours. Communication

Serial RS232 or RS485 interfaces for remote supervision and PC-based configuration. Programmability

Fully customizable input/output functions and operating parameters. Monitoring & Alarm Codes

The 31 RGAM 12 actively supervises engine and alternator health, displaying specific codes for faults: A01: Low oil pressure. A02: Engine overheating. A05/A06: Low or high battery voltage. A10/A11: Low frequency or generator overload. A13: Emergency stop activated. Remote Supervision lovato 31 rgam 12 user manual

Users can extend the controller's capabilities using the RGAM.EXE software. This allows for:

Remote Monitoring: Real-time viewing of status, alarms, and event logs (up to 255 events) via modem or GSM.

Parameter Management: Consulting and modifying setup parameters protected by password access.

Network Integration: Ability to connect up to 32 units under one central control system using RS485.

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. 

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.

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. Without specific details from the Lovato 31 RGAM

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.

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

Lovato 31 RGAM 12 is a microprocessor-based automatic transfer and control unit designed for 12VDC stand-by generating sets. It manages the automatic starting of a generator during mains power failure and controls the changeover between mains and generator power sources. Амитрон-ЭК 1. Core Operating Modes

The unit features four primary operating modes, selectable via the front panel keys: OFF / RESET

: Disables the generator and inhibits control inputs. If the engine is running, selecting this mode stops it immediately without a cooldown period. It is also used to reset persistent alarms. MANUAL (MAN) : Allows direct control of the engine and load. Use the keys to manage the engine, and the (Mains) and

(Generator) keys to manually switch the load between sources. AUTOMATIC (AUT)

: The unit monitors the mains voltage. If the voltage fails or goes out of preset limits, the unit automatically starts the generator and switches the load. It returns to mains power and stops the generator once stable utility power is restored.

: Used to verify generator operation. The engine starts immediately; however, the load only switches to the generator if the mains power actually fails during the test. 2. Front Panel & Interface

The interface provides real-time monitoring and status indication: 3-Digit Display

: Shows RMS readings for mains/generator voltage, frequency, battery voltage, and engine hours. LED Indicators L1-L2, L2-L3, L3-L1 : Indicate the presence of mains phases.

: Lights up when a valid start signal (from alternator or generator voltage) is detected. NET / GEN Contactors

: Yellow LEDs indicate which contactor is currently energized. 3. Common Alarm Codes This is the most referenced part of the 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.

: Generator voltage failure (out of limits during operation). : Emergency stop (input contact opened). : Maintenance required (based on programmed engine hours). 4. Advanced Features & Configuration Maintenance Reset : To clear the maintenance alarm, put the unit in mode and hold the button for 5 seconds. Automatic Test Interval : You can program periodic self-tests. To adjust, hold SELECT/RESET to enable/disable or set the day interval. PC Connection : The unit includes an RS232 serial port
