General
DGK-03 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.
With the help of the button ,the adjustment is value of display on the left display. 4 seconds later, displayers show voltage values.
Once the device is energized, firstly the pre-adjusted set values are displayed and 2 seconds later voltage values appear. When R, S and T phases are between the adjusted voltage values, relay (Out) LED is on and contact (2-3) closed. If any between phase-phase is over high voltage set value, it holds for 3 seconds(fixed) and then relay (Out) LED is off, high voltage error (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.
