Entes GKRC-02F voltage monitoring relay GKRC-02F Contact type SPDT-CO (8 A) GKRC-02F Data Sheet

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.

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).

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.

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.

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

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.

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.
