General
DGK-04F voltage control relays are designed to block three-phase loads malfunctions arising from network.

Usage and Working Principle
Make the connections of the device in accordance with connection scheme.

To Adjust High Voltage Set: Value checking the value of display on the left, adjust the desirable value of (u>) button . Once you move the button , set value will be displayed.
To Adjust Low Voltage Set: Value checking the value of display on the left, adjust the desirable value of (u)LED is on and contact (2-3) opened. Whichever phase-phase voltage value is high, its display blinks, contact (2-3) opened. When voltage values declines 5V below set value, it holds for adjusted (t) knob time and then relay (Out) LED is on, high voltage error(U>) LED is off and contact (2-3) closed.

If any phase-phase declines below low voltage set value, it holds for adjusted (t) time and then relay(Out) LED is off, low voltage error LED(U)...........: 400V - 460V
Low Voltage (U<)............: 230V - 360V
Waiting (t).......................: 0,1sec - 10sec.
Display..................: 3x 3digit 9mm display and leds
Measurement Precision...: %1
Connection Type..............: Terminal connection
Contact....................:5A/250V AC (Resistive Load)
Cable Diameter.................: 2,5mm
Weight................................: Max. 220gr.
Panel Hole Sizes................: 91x91mm
Mounting...........................: Vertical assembled in
the panel or assembled on the din rail
