Gmr-32b Phase Controller Manual [new]

Read all safety guidelines before attempting installation or maintenance.

Directly snaps onto a standard HT35 / 35mm guide rail system.

If you need help configuring this device for your specific setup, please let me know:

⚠️ The sampling lines for this protector must be connected exclusively on the line (power) side of the three-phase distribution network. Never install the controller on the load output side of variable frequency drives (VFDs) or soft starters, as high-frequency harmonics will damage the micro-control circuitry. Terminal Connections and Wiring Matrix gmr-32b phase controller manual

Triggers under dynamic or static phase breakage where any single phase (R, S, or T) drops out completely. It also activates if the three-phase voltage unbalance rate—calculated via the formula [(Umax - Umin) / Uave] * 100 —exceeds . This fault holds top priority and shuts down equipment instantly to prevent motor burnout. 3. Phase Reversal / Reverse Phase (Red Indicator)

Confirm all high-voltage terminal screws are torqued to specification (1.2 Nm).

Connect the positive loop wire to the 4-20mA terminal and negative to COM . Read all safety guidelines before attempting installation or

Wire the output side to your motor starter circuit or contactor coil.

Detects asymmetry in the three-phase power. Standards: Complies with IEC60947-1:2007 and IEC61000. Installation & Wiring Guide Installation is typically done on a standard DIN rail .

The GMR-32B is engineered for standard industrial power environments with the following typical ratings: 380 VAC Operating Frequency: 50/60 Hz Protection Functions: Phase Sequence: Prevents reverse motor rotation. Never install the controller on the load output

Monitoring compressor power supply. 2. GMR-32B Technical Specifications and Features

Cause: Downstream load current exceeded safe operating parameters.

Mount the unit vertically inside an IP54-rated industrial electrical enclosure.
