Frequently Asked Questions - GKRC-21E ENTES

What does the 'No Phase' alarm indicate?

The 'No Phase' alarm triggers when there is no connection in any of the phases (L1, L2, L3). Check all phase connections.

What triggers the 'Phase Sequence' alarm?

The 'Phase Sequence' alarm triggers if the phases L1, L2, L3 are not in clockwise order. Verify the phase sequence.

How is the 'Voltage Unbalance' alarm defined?

This alarm is triggered if any phase-to-phase voltage deviates by a set percentage (x%) from the average of the phase-to-phase voltages.

What is the power supply voltage range for the GKRC-21E?

The power supply voltage range is 85-300 VAC.

What are the operating and storage temperature limits?

The operating temperature is -20 to +70 °C, and the storage temperature is -25 to +80 °C.
