Often associated with power supply protectors and PLC-compatible modules (e.g., GLOFA-GMR series). Aksa Mühendislik Installation & Safety Guidelines Power Off:

The GMR-32B monitors the sequence of the three phases. If the phases are incorrectly connected (e.g., L1, L3, L2), the device will lock out the start command, preventing the motor from reversing unexpectedly. This is especially crucial for equipment like compressors or elevators, where reversing can cause catastrophic mechanical failure. gmr32b phase controller manual

Press and hold the key for 3 seconds to enter configuration mode. Use the UP and DOWN arrows to cycle through parameters. Press SET briefly to edit a selected parameter.

Locate an open segment on a standard inside your control cabinet.

💡 : Always ensure the power is completely disconnected before wiring or inspecting the controller to prevent electric shock. GMR-32B Phase controller, 300-400V 50/60HZ - JIEFENG This is especially crucial for equipment like compressors

If you can provide a photo of the unit or the manufacturer listed on the casing, I can help locate the specific manual for that brand.

Verify that cooling fans spin freely without excessive noise. Fault Codes and Troubleshooting Symptom / Error Code Potential Cause Remedial Action Load short circuit or excessive startup surge. Check load impedance; increase Soft Start time ( P-02 ). E-02 (Overheating) Poor ventilation or fan failure. Clear ambient obstructions; verify fan functionality. E-03 (Phase Loss) Missing input phase or blown input fuse. Measure voltage across L1 and L2 terminals. No Output Display Total loss of control power. Check control fuse or primary power supply connections. Output Always Max Thyristor short-circuit (puncture) or bad input signal. Press SET briefly to edit a selected parameter

) facilitates direct space-saving integration within cramped electrical control enclosures.

: Detects phase reversal (before starting) and dynamic/static phase loss, over/under-voltage, and phase imbalance during operation.
