<;) 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.
Phase protection is available on DGK-04F/DGK-04PF. When phase sequence is reversed or phase loss, contact (2-3) opened and phase sequence error (X1) LED is on.
