Lovato 31 Rgam 12 User Manual (PREMIUM × RELEASE)

Lovato 31 RGAM 12 is a microprocessor-based control unit designed for the automatic management of standby generating sets. It serves as an Automatic Mains Failure (AMF) controller, meaning it automatically starts the generator and handles the load changeover when it detects anomalies in the main power supply. Core Functionality Automatic Transfer (AMF):

Monitors the mains power supply and triggers the generator start cycle if voltage or frequency falls outside preset limits. Engine & Alternator Supervision:

Tracks critical engine parameters (like oil pressure and temperature) and alternator functions to ensure safe operation. Voltage Control:

Provides three-phase control for the mains (70–624VAC) and single-phase control for the generator. Operation Modes: Includes four distinct modes: (disabled), (manual start/stop), (automatic standby), and (periodic manual or automatic testing). Key Specifications & Features Power Supply:

Operates on a 12VDC battery supply with a range of 6.2–16.5VDC. Interface:

Features a 3-digit LED display for readings (voltage, frequency, battery, hours) and 16 status LEDs. Remote Monitoring: lovato 31 rgam 12 user manual

Supports RS232 serial communication for remote control and troubleshooting via PC or modem. The "RC" version (31 RGAM 12RC) includes an RS485 port for networking up to 32 units. Event Logging:

Maintains a log of the last 255 events and alarms for maintenance and diagnostic purposes. Automatic Test Cycle:

Allows for programmable periodic test runs to ensure the generator is ready for emergencies. Common Alarm Codes The unit displays specific codes to indicate faults: Low oil pressure Engine overheating Failure to start (after preset attempts) Generator voltage failure Maintenance required (based on running hours)

Q3: What is the difference between RGAM 12 and RGAM 18?

A: The current range. RGAM 12 = 9–12 A. RGAM 18 = 12–18 A. Choose based on motor FLA. Lovato 31 RGAM 12 is a microprocessor-based control

2. Asymmetric Window Mode (Over & Under Voltage)

Most users set these relays for "Under voltage" only, but the manual describes a more protective "Window Mode."

The Feature: The device can detect if the voltage goes too low OR too high.
How it helps: If you have a generator or unstable grid power, voltage can spike dangerously high (e.g., >260V), which damages electronics.
Manual Instruction: Look for the wiring diagram that shows the relay opening if the voltage exceeds the "Max" setting OR drops below the "Min" setting. This provides full protection for sensitive equipment.

Approvals:

IEC/EN 60947-4-1
UL 60947-4-1 (File No. E219842)
CSA C22.2 No. 60947-4-1
CE (European conformity)
EAC (Eurasian Conformity)

Steps:

Locate the large rotary dial on the front face.
Turn until the arrow aligns with the desired amperage (9 to 12).
For compensation of ambient temperature (if the relay is in a hot panel >40°C), derate by 5–10%.

6. Auxiliary Contacts and Control Circuit Integration

The 31 RGAM 12 includes built-in auxiliary contacts:

| Contact | State in Normal | State in Trip | |---------|----------------|----------------| | 95-96 (NC) | Closed | Open | | 97-98 (NO) | Open | Closed |
