If your GMR32B model has adjustable potentiometers (small dials on the front face), here is how to set them. If your model is fixed, skip to the indicator lights.
The GMR32B is suitable for any industrial or commercial three-phase system where voltage and phase integrity are critical, including:

This manual serves as a definitive resource for electrical technicians, facility engineers, and system integrators tasked with installing, configuring, wiring, and servicing the GMR-32B three-phase protection relay . Technical Specifications & Operating Parameters
The GMR32B is typically available in several variants (e.g., GMR32B1, GMR32B3, GMR32B6) which differ in their specific voltage ranges, adjustment options, or the number of output contacts. When ordering, specify the exact part number and the required . Additional options may include an external current transformer (CT) for specific overload protection. If your GMR32B model has adjustable potentiometers (small
0-10V DC, 4-20mA, 1-5V DC, or manual potentiometer (typically 10kΩ).
Most GMR32B units feature an 8-terminal design. Here is how the standard pinout typically looks: 0-10V DC, 4-20mA, 1-5V DC, or manual potentiometer
Product: GMR32B Phase Controller Purpose: Automatic control and protection of three-phase electric motors and loads, ensuring proper phase sequence, phase presence, voltage imbalance protection, and automatic phase switching/transfer.
