GKM-02F 3 * 380VAC with-Neutual Three-Phase Phase Failure, Sequence, Under&Over Voltage Relay

relayGeneralVoltage control relays are designed to protect devices with sensitive operating voltage values from faults that may be caused by mains voltage.Usage and Working PrincipleMake the connections of the device in accordance with connection scheme.Set the required settings of the device according to the operating voltage values of the load. When the device is energized, if the voltage values are narmal according to the set values, the relay gets activated and the relay LED() is turned on.(In the case of models with phase sequence control, the phase sequence must also be correct. When the voltage values go out of the set values, the related fault LED is on, it waits until the delay time (DT), after the time has elapsed, the relay gets de-activated and the relay LED goes out. When the voltages return to their normal values, the device waits until the reset time (RT), after the time has elapsed the relay gets activated and the relay LED is turned on.The High Voltage Protection function is deactivated when the HV control knob is set to Off.The Low Voltage Protection function is deactivated when the LV control knob is set to Off.Relay is Activated: 2 (COM) and 3 (NC) short circuit, 1 (NC) and 2 (COM) open circuit.Relay is De-activated: 2 (COM) and 1 (NC) short circuit, 3 (NC) and 2 (COM) open circuitRequired Settings and Error NotificationsHV: High Voltage Set Value, when the voltage rises above this value, HV LED is on.LV: Low Voltage Set Value, when the voltage drops below this value, LV LED is on.DT: Delay Time, is the time to wait before entering the fault.RT: Reset Time, is the time to wait for the relay to pull when the voltages return to normal.LED Notifications By ErrorsProtection FunctionsHigh Voltage Protection- To enter the error state: If one or more of the phases goes above the high voltage set value, the HV LED is on, the device waits untilthe set delay time (DT), after th
