Gmr-32b Phase Controller Manual Official

Heatsink temperature exceeded 85°C. Check your cooling fan function and clear any airflow blockages.

The GMR-32B is designed for flexible mounting within a control panel. Its compact size of approximately allows for easy installation even in crowded enclosures.

The exact you are controlling (e.g., resistive heater, inductive motor)?

Connected to external alarm systems, warning buzzers, or industrial programmable logic controllers (PLCs) to signal a system trip. Diagnostic LED Indicators and Status Reading

install the GMR-32B on the output side of a variable frequency drive (VFD); it must be installed on the supply side. Troubleshooting with LED Indicators gmr-32b phase controller manual

: Backed by detailed documentation and a proven track record in demanding industrial environments.

Two normally open (NO) and two normally closed (NC) contacts, which are electrically inseparable. Contact Capacity: 250 VAC @ 6A or 30 VDC @ 3A.

If a phase is lost or voltage is too high/low, the device will immediately open the control contact to protect the load. 5. Troubleshooting the GMR-32B Phase Protector

Unlike basic current-sensing breakers, the GMR-32B samples voltage topology directly to detect system errors independent of load sizing or line current imbalances. Heatsink temperature exceeded 85°C

The GMR-32B controller performs three primary functions: Its compact size of approximately allows for easy

When the incoming voltage rises above or falls below a preset percentage of the nominal voltage (typically adjustable to approx. ±15%), the respective "过压" or "欠压" LED illuminates. If the voltage remains outside the safe range for the designated delay (approx. 7 seconds), the output relay de-energizes. Once the voltage returns to normal levels, the delay timer resets and the unit will automatically restore the relay to its normal state.
