[updated] - Gmr-32b Phase Controller Manual

Connect the outer legs of a 10k-ohm potentiometer to Terminal 1 (+10V) and Terminal 3 (GND). Connect the center wiper leg to Terminal 2 (INPUT+). 4. Programming and Parameter Configuration

I can provide a step-by-step wiring guide tailored exactly to your equipment.

Connect the positive control wire to Terminal 2 and the ground wire to Terminal 3.

A green light often indicates that the phase sequence is correct and voltage is within the accepted range.

High voltage conditions that can burn out motors.

Use stranded or solid wires between 0.25 to 1.5 mm² (AWG24 to AWG16). 💡 Visual Indicators The device typically features LEDs to signal status: PWR (Green): Indicates power supply is present. OUT (Yellow): Indicates the relay output is active. Connect the outer legs of a 10k-ohm potentiometer

Five distinct front-facing LED indicators provide clear visual troubleshooting data for lineside issues:

Do not install this unit on the output side of a variable frequency drive (VFD); it must be sampled from the main power supply side.

Two normally open (NO) and two normally closed (NC) electrically separate contacts Programming and Parameter Configuration I can provide a

The GMR-32B is a solid-state phase angle controller designed for resistive and inductive loads. It adjusts the voltage applied to a three-phase load by chopping the AC sine wave. This device is commonly used in:

Proper wiring is critical to prevent ground loops, signal interference, and catastrophic hardware failure. Always isolate high-voltage lines from low-voltage control signals. Low-Voltage Control Terminals (Signal Input)

Verify load resistance and check for short circuits.
