DGK-03 3 * 380VAC Three Phase Overvoltage Protection Relay Seting Digital

relayGeneralDGK-03 voltage control relays are designed to block three-phase loads malfunctions arising from network.Usage and Working PrincipleMake 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.MaintenanceSwitch off the device and release from connections. Clean the trunk of device with a swab. Don't use any conductor or chemicalmight damage the device. Make sure device works after cleaningWarningsPlease use the device according to the manual.Don't use the device in wet.Include a switch and circuit breaker in the assembly.Put the switch and circuit breaker nearby the device, operator canreach easily.Mark the switch and circuit breaker as releasing connection for device.SpecificationsOperating Voltage(Un)....: 3 x 380V ACOperating Frequency.......: 50/60 Hz.<;;6VAOperating Temperature..: -20°C.....+55°CHigh Voltage (U>)...........: 400V - 460VWaiting (t)..
