General
DGK-04 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.
<;) button.
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.
<;) is on and contact (2-3) opened. Whichever phase-phase voltage value is low, its display blinks, contact (2-3) opened. When voltage values inclines 5V above set value, it holds for adjusted (t) knob time and then relay (Out) LED is on, low voltage error LED(U) is off and contact (2-3) closed.
