380V AC nominal (optimized for 300V to 400V operational envelopes). Frequency Range: 50 / 60 Hz auto-sensing. Internal Power Consumption: ≤is less than or equal to 10 VA . Conventional Heating Current ( Ithcap I sub t h end-sub ): 8A maximum.

| LED Color/Designation | Condition | Meaning / Action Required | | :--- | :--- | :--- | | | ON | The three-phase supply is within acceptable limits, the phase sequence is correct, and the output relay is energized. | | Yellow (Phase Loss/ Imbalance) | ON | One or more phases are missing, or a severe voltage imbalance (>20%) is detected. Check fuses, connections, or the supply. | | Red (Reverse Phase) | ON | The phase sequence of the incoming supply is incorrect (e.g., L1 and L3 swapped). Swap any two of the three phases at the input to the GMR32B. | | Yellow (Overvoltage) | ON | The supply voltage has exceeded the overvoltage threshold. Check the supply voltage (should be ≤115% of nominal). | | Yellow (Undervoltage) | ON | The supply voltage has fallen below the undervoltage threshold. Check the supply voltage (should be ≥85% of nominal). |

GMR-32B Phase Controller Manual: Installation, Wiring, and Troubleshooting Guide

: It ensures the motor only runs when the power sequence is correct (e.g., A-B-C). If phases are reversed, it cuts power to prevent the motor from spinning backward, which could strip gears or damage bearings. Over-Voltage & Under-Voltage Protection gmr32b phase controller manual

, you can find replacement units and technical details on sites like Do you need a wiring diagram

Use shielded twisted-pair wiring for all analog inputs. Ground the shield at one end only. Thermal overload protection has tripped due to overheating.

Main line voltage is missing or internal control fuse blown. 380V AC nominal (optimized for 300V to 400V

Once wired, the GMR32B must be configured to interpret the incoming control signals and deliver the desired power profile. Step 1: Input Signal Selection

Swap any two of the incoming phase wires ( ) to reverse the phase sequence to 5. Applications The GMR32B is widely used in: Elevators: Protecting against reverse rotation.

Symptom: Motor hums but does not start, yet the GMR-32B shows Green Conventional Heating Current ( Ithcap I sub t

The terminal block of the GMR32B is divided into high-voltage power terminals and low-voltage control signals. Mixing these connections will permanently damage the controller.
