Installation and Mounting Dimensions

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

: The internal switching mechanism provides an electrically inseparable circuit with separate NC and NO pathways. Wire the chosen terminal pair inline with the primary electromagnetic contactor’s command loop. If a fault occurs, the loop de-energizes, snapping the contactor open and separating the motor load from the line. LED Status Diagnostics gmr-32b phase controller manual

Instantaneous response to input control changes. 5. Calibration and Onboard Adjustments

: 79 mm x 23 mm x 79 mm (3.11″ x 0.91″ x 3.11″) Weight : 150g (5.29 oz) the loop de-energizes

The GMR-32B features separated high-voltage power terminals and low-voltage control terminals.

Closed during a fault event. Wire this path directly to external pilot lights or PLC error inputs to announce a system trip. Visual Diagnostic Matrix (LED Indicators) gmr-32b phase controller manual

⚠️ : The GMR-32B must always sample power from the input/power side of the three-phase electrical supply. Never install the phase controller on the output side of variable frequency drives (VFDs), inverters, or variable frequency currents. Doing so will cause immediate unit failure or severe diagnostic errors due to pulse-width modulation harmonics. Mounting the Base
