Gmr-32b Phase Controller Manual -

Are you troubleshooting a or looking for wiring diagrams for a particular motor type?

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:

| Symptom | Possible Cause(s) | Corrective Action | | :--- | :--- | :--- | | | - One or more phases missing at input. - Loose connection on L1, L2, or L3 terminal. | Check incoming power with a multimeter. Ensure all three phases are present and correctly terminated at the controller. | | "逆相" (Reverse Phase) LED is ON. | - The phase sequence of the L1, L2, L3 supply is incorrect. | Swap any two of the three phase input wires at the controller's L1, L2, or L3 terminal. For example, swap L1 and L3. | | "过压" or "欠压" LED is ON. | - Supply voltage is outside the preset range. - Voltage threshold may be set incorrectly. | Measure the incoming voltage. Verify voltage is within the unit's rated range. Consult manufacturer documentation for adjusting set points. | | "缺相" (Phase Loss) LED is ON. | - One of the three phases is completely missing. - A severe voltage imbalance (>10%-20%) exists. - Loose connection or faulty fuse upstream. | Check all three supply fuses/breakers. Measure each phase-to-phase voltage. Tighten all connections. A significant imbalance indicates a problem with the supply or transformer. | | Relay chatters or trips randomly for a few seconds. | - Momentary voltage sags or spikes. - Loose wiring in the control circuit. | Check all wiring for tightness. The 7V hysteresis helps prevent this, but if the supply is very noisy, consult the manufacturer for application guidance. | | Equipment starts but then trips immediately. | - The control circuit is wired to the NO contact. - A phase loss or imbalance condition exists. | Verify the control circuit is wired through the NC (Normally Closed) relay contact. Check the "缺相" and "逆相" indicators. |
