The GMR-32B is a sophisticated micro-processor based control module designed for automatic start-up and management of diesel/gas generator sets. It provides comprehensive protection, monitoring, and control for the generator and the engine. This device is typically used in Automatic Mains Failure (AMF) applications where the generator acts as a standby power source. This report summarizes the key aspects of the user manual, covering installation, parameter configuration, and operational procedures.

This usually indicates the phase sequence is incorrect. Power down and swap any two of the three input wires (L1/L2/L3) to correct the rotation. Relay Not Engaging:

The GMR-32B is a reliable, "set-it-and-forget-it" industrial relay. It excels at detecting phase-related faults before they cause permanent motor burnout, making it a cost-effective insurance policy for expensive machinery. Key Performance & Features Comprehensive Fault Detection

What is your exact ? (e.g., 24VDC, 220VAC)

| Indicator | Color / Label | Meaning / What to Do | | :--- | :--- | :--- | | | Green / 'Normal' | This should be the only lit LED. It confirms correct phase sequence (L1-L2-L3) and voltage is within tolerance. | | Reverse Phase | Red / 'Reverse' (or 'Inverse') | Two phases are swapped. Immediately swap any two of the three incoming power leads (e.g., L1 and L2) at the input terminal block to correct this. | | Phase Loss | Yellow 'Upper' / 'Loss' | One or more phases is missing. Check upstream fuses, breakers, and connections. The GMR-32B's protection is unaffected by load current —it monitors pure voltage. | | Over Voltage | Yellow 'Lower' / 'OV' | Supply voltage exceeds the set threshold. Verify incoming voltage to the facility and check if an upstream tap changer or regulator needs adjustment. | | Under Voltage | Yellow 'Lower' / 'UV' | Supply voltage has dropped below the set threshold. Inspect for loose connections, heavy load startup, or utility brownout conditions. |
