Gmr32b Phase Controller Manual -

For most heating loads, set S1-3 = OFF (phase-angle), S1-4 = OFF, S1-5 = ON. Burst firing (S1-3=ON) reduces RF interference but may cause flicker in incandescent lamps.

| Symptom | Probable Cause | Solution | | :--- | :--- | :--- | | | Control signal issue or SCR shorted. | Check input signal (is it >20mA or >10V?). Check SCR health. | | No Output | Missing control signal or blown fuse. | Measure control terminals. Check input line fuses. | | Erratic Output | Poor connection or feedback loop issue. | Tighten terminals; check for ground loops on signal wire. | | Overheating | Insufficient cooling airflow. | Ensure fan (if equipped) is running; clean dust from heat sink. | gmr32b phase controller manual

⚠️ Always disconnect power before wiring. Ensure your voltage matches the device rating (e.g., 220V, 380V, 440V). For most heating loads, set S1-3 = OFF

: It ensures that the three phases are in the correct order. This is vital for motors; if the sequence is reversed, a motor will spin backward, which can cause severe physical damage to bearings, windings, and mechanical loads. | Check input signal (is it >20mA or >10V
