Gmr-32b Phase Controller | Manual

Observe the LED; its brightness should increase smoothly in proportion to the signal, indicating correct phase-angle calculation. 4. Parameter Adjustment and Calibration

Ensure the unit is positioned away from high-heat components like braking resistors or the SCR heatsinks themselves. Step 2: Signal Configuration (DIP Switch Settings)

If your GMR-32B includes current limiting (often via CT inputs), adjust VR3 so that peak load current stays below 32A.

⚠️ 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.

: Always install on the line/supply side . Placing the relay on the output side of a variable frequency drive (VFD) will cause it to malfunction. Reference Manual

: If direct wall or panel plate mounting is preferred, locate the integrated slider accessories at both sides of the unit's bottom piece. Push these components outward firmly to expose the two preset M4 screw holes. Fasten securely to the backplate.

Sets the baseline output when the control signal is at zero. Turn clockwise to establish a pre-heat current or baseline voltage. Observe the LED; its brightness should increase smoothly

Identifies structural voltage asymmetry across lines, which causes excessive heat buildup in electric motor windings. Installation and Mechanical Mounting

| Parameter | Trip Threshold | Action Time | | :--- | :--- | :--- | | | Inverted phase sequence (L1-L2-L3) | ~0.1-2 seconds (depending on model) | | Phase Loss | Any single phase missing | ~1-2 seconds | | Over/Under Voltage | Adjustable, ±15% of nominal | ~3-8 seconds | | Voltage Imbalance | >10-20% deviation between phases | ~2-5 seconds | | Reset Type | Automatic Reset (returns to operation once conditions normalize) |

The GMR-32B supports several firing modes: Step 2: Signal Configuration (DIP Switch Settings) If

A: Yes. Many distributors and manufacturers produce the same device under different branding. 'ABJ1-W' is a common alternative labeling for what is effectively the GMR-32B series of phase controllers.

The following specifications apply to the GMR-32B and GMR-32B Smart Series:

: Illuminates if any single phase (U, V, or W) completely fails or drops below the dynamic/static threshold. It also activates during significant line unbalance conditions.
