BREAK OF THE NEUTRAL CONNECTION FOR DEVICES WITH NEUTRAL
In devices with neutral, Phase-Neutral measurements are taken. If the neutral cable breaks, the neutral point of the system shifts because of the asymmetrical phase loading. The device continues the take measurements according to the shifted neutral system point.

Delay=20sn
General:
DGRC-01, GKRC-01/02/02F/02FA/03/03F relays are delay-off and delay-on capable voltage protection relays which have adjustable over and under voltage limits. They are used in 1-phase and 3-phase Air Conditioning systems, in electronical command and control systems, for protection of capacitors in compensation systems and for protection of equipments like motors.
Utilization and Working Principle:
By using the Over Voltage(Max.) and Under Voltage(Min.) adjustment knobs on the front side, the over and under voltage limits of the system that will be protected is determined.
The Delay knob on the front is used commonly for both the adjusted over voltage faults and adjusted under voltage faults.
The Reset Delay knob on the front is used commonly for all faults. The over voltage and under voltage protection options can be deactivated separately(By
adjusting the Max. and Min. knobs to OFF position).
Protection Functions:
a)Over Voltage Protection: GKRC-01 / 02 / 02F / 02FA /03 / 03F / M2
If one or many of the measured voltage(Phase/Phase-Phase) values are over the limit of the adjusted Over Voltage Value(Umax), the “U>” light turns on and the adjusted Delay time starts to count. When the Delay time is up, the relay of the device breaks the connection and the “OUT” light turns off. When all of the measured voltages fall under the adjusted Over Voltage Value, “U>” light turns off and adjusted Reset Delay time starts to count.When the Reset Delay time is up, the relay of the device makes contact and “OUT” light turns on. If one or many of the measured voltage(Phase/Phase-Phase) values go over the “1,5xUn” limit, “U>” light turns on, the relay of the device breaks the connection and “OUT” light turns off. When the Over Voltage adjustment(Max.) knob is adjusted to the “OFF” position, the Over Voltage Protection function is disabled.
b)Under Voltage Protection: DGRC-01, GKRC-02 / 02F / 02FA/ 03 / 03F / M2
If one or many of the measured voltage(Phase/Phase-Phase) values are under the limit of the adjusted Under Voltage Value(Umin), the “U<” light turns on and the adjusted Delay time starts to count. When the Delay time is up, the relay of the device breaks the connection and the “OUT” light turns off. When all of the measured voltages rise over the adjusted Under Voltage Value, “U<” light turns off and adjusted Reset Delay time starts to count.When the Reset Delay time is up, the relay of the device makes contact and “OUT” light turns on. If one or many of the measured voltage (Phase/Phase-Phase) values go under the “0,5xUn” limit, “U<” light turns on, the relay of the device breaks the connection and “OUT” light turns off.
When the Under Voltage adjustment (Min.) knob is adjusted to the “OFF” position, the Over Voltage Protection function is disabled.
c) Phase Sequence Protection: GKRC-02F / 02FA / 03F

Phase Sequence Fault Diagram
If there is a change in the p h a s e s e q u e n c e f o r whatever the reason, only the “ON” light turns on and the relay of the device breaks the connection without any delay.
Insufficient Supply Voltage: DGRC-01, GKRC-01 / 02 / 02F / 03 / 03F / M2
DGRC-01, GKRC-01 / 02 / 02F / 03 / 03F / M2 are supplied from a 3 Phase capacitive source. The supply voltage on these devices equals to the mean value of voltages from all three phases. If this mean value is less than half the supply voltage, the relay gives an insufficient supply voltage warning (U< and U> LEDs flash in that order) and the relay breaks contact without delay.
DGRC-01,GKRC-01 / 02 / 02F With Neutral => (VL1+VL2+VL3)/3 < 115 VAC (F-N) GKRC-03 / 03F Without Neutral => (VL12+VL23+VL31)/3 < 200 VAC (F-F)
PRECAUTIONS FOR INSTALLATION AND SAFE USE
Failure to follow those instructions will result in death or serious injury.
Disconnect all power before working on equipment.
When the device is connected to the network, do not remove the front panel. Do not try to clean the device with solvent or the like.
Only clean the device with a dried cloth.
Verify correct terminal connections when wiring.
Electrical equipment should be serviced only by your compedent seller.
Mount device to the panel
