Frequently Asked Questions - GKRC-22E ENTES

What is the GKRC-22E voltage protection relay used for?

The GKRC-22E monitors three-phase power systems and triggers alarms for faults like phase loss, phase sequence reversal, voltage unbalance, under/over voltage, and under/over frequency.

What is the power supply range for the GKRC-22E?

The device accepts a power supply voltage (ΔU) of 85–300 VAC.

How many output contacts does the GKRC-22E have?

It has 2 C/O (changeover) relay contacts rated at 8A / 2000 VA.

What are the operating and storage temperature ranges?

Operating temperature: -20 to +70 °C. Storage temperature: -25 to +80 °C.

What does the 'Phase Sequence' alarm mean?

The Phase Sequence alarm triggers if the phases L1, L2, L3 are not connected in a clockwise (positive) sequence.

How do I set the language on the GKRC-22E?

On startup, the device shows a slideshow of languages. Press OK when the desired language screen appears to select it.

What is the protection class of the GKRC-22E?

The front panel has IP41 protection; terminals are rated below IP20.

Can the GKRC-22E be mounted on a DIN rail?

Yes, the device is designed for rail mounting (DIN rail).

What does the 'Voltage Unbalance' alarm indicate?

This alarm triggers when any phase-to-phase voltage deviates by a set percentage from the average of the three phase-to-phase voltages.

How do I reset the alarm after a fault?

Alarms are typically reset automatically when the fault condition clears. For manual reset, refer to the user manual or use the OK button during alarm display.

GKRC-E Series Voltage Protection Relay Quick Start Manual

EN Please refer to user manual with the general

instructions document which can be downloaded from the web site: www.entes.eu

WARNING: This equipment must be installed only by

professionals. The manufacturer shall not be held

responsible for failure to comply with the instructions

in this manual. Please read the instructions in this

manual before performing installation and take note

of the following precautions.

1. Ensure that all incoming AC power and other power

sources are turned OFF before performing any work on the

instrument. Failure to do so may result in serious or even fatal injury and/or equipment damage.

1. Before connecting the instrument to the power source,

check the labels on the back of the instrument to ensure

that your instrument is equipped with the appropriate power supply voltage, input voltages and currents.

1. Under no circumstances should a damaged instrument

be connected to a power source

1. To prevent potential fire or shock hazard, do not expose

the instrument to rain or moisture

1. Do not open the instrument under any circumstances when it is corrected to a power source.

2. Always supply the device with the correct rated voltage
