Electromechanical Relays
General
DGK-01 and DGK-01W voltage control relays are designed to block monophse loads malfunctions arising from network.
Usage and Working Principle
To set the high voltage value: set the "U>" control knob to the desired value.
<;;" control knob to the desired value.
To set the delay time: set the "t" control knob to the desired value.
The set values is displayed on the display when adjusting with the setting knobs.2 seconds after releasing the set knob then on the display shows the measured voltage value.
<;;" voltage set values, the "Out" LED turns on and the relay is energised.
Protection Functions
High Voltage Protection - To enter the error state: lf the voltage goes above the high voltage set value, the "U>" LED is on, the device waits until the set delay time "t", after the time has elapsed the relay gets de-activated and the "Out" LED is off.
High Voltage Protection - Exiting the error state: When the voltage drops below 5V of the high voltage set value, the device waits for the delay time "t". After the time passes, the "U>" LED is off, the relay gets activated and the Out LED is on.
<;;" LED is on, the device waits until the set delay time "t", after the time has elapsed the relay gets de-activated and the "Out" LED is off.
<;;" LED is off, the relay gets activated and the "Out" LED is on.
Relay States
Relay is Activated: 2(COM) and 3(N
