DGK-01 is designed to protect the devices having precise operating voltage values against errors likely to arise from mains .Voltage. There are high (U>) voltage set buttons, low (U<) voltage set buttons,s and error latency (t) time set buttons on the
device. Please make the connection of the device according to the diagram. Energize the device. When the device is energized for the first time, contactor terminals no. 1(NC) and 2(COM) short-circuit and contactor terminals no. 2(COM) and 3(NO) are open circuits. Adjust the high voltage, low voltage, and error latency time values depending on the load you will use. While adjusting the values via the set button, the value being adjusted is shown on the display. If the voltage value is within the range of normal values, the relay led (OUT) lights up; contactor terminals no. 1(NC) and 2(COM) become opencircuit and contactor terminals no. 2(COM) and 3(NO) become short-circuit. If the voltage value exceeds the high voltage set value, the high voltage (U>) error led lights up and if the voltage value does not drop below the normal value in 2 seconds, a high voltage error occurs on the device. In this position, the relay led turns off, contactor terminals no. 1(NC) and 2(COM) become short-circuit and contactor terminals no. 2(COM) and 3(NO) become open-circuit. When the voltage value drops below the high voltage set value by 5V, the high voltage error led turns off and the device starts to count the error latency (t) time. When the error latency time is up, the relay led lights up and contactor terminals no. 1(NC) and 2(COM) become open-circuit and contactor terminals no. 2(COM) and 3(NO) become short-circuit.
If the voltage values drop below the low voltage set value, the low voltage (U<) error led lights up and if the voltage values
do not increase to the normal value within the error latency time, low voltage error occurs on the device. In this position,
the relay led turns off, contactor terminals no. 1(NC) and 2(COM) become short-circuit and contactor terminals no.
2(COM) and 3(NO) become open-circuit. When the voltage value exceeds the low voltage set value by 5V, the low voltage error led turns off and the device starts to count the error latency (t) time. When the error latency time is up, the relay led lights up and contactor terminals no. 1(NC) and 2(COM) become open circuit and contactor terminals no. 2(COM) and 3(NO) become short-circuit.
