GKM-11 220VAC MonoPhase Overvoltage & Undervoltage Protection Relay

relayGeneralVoltage control relays are designed to protect devices with sensitive operating voltage values from failures 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 te load. When the device is energized, if the voltage values are normal according to the set values, the relay gets activated and the relay LED() is turned on. 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.Disable to ProtectionThe 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. The Off stage is limited to 140V. If the voltage falls below 140V while in this stage, the relay is deactivated and the LV Led is flashes.Relay Activated/De-activated StatusRelay 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 circuit.Required Settings and Error NotificationsHV Control Knob: High Voltage Set Value, when the voltage rises above this value, HV LED is on.LV Control Knob: Low Voltage Set Value, when the voltage drops below this value, LV LED is on.OT Control Knob: Delay Time, is the time to wait before entering the ailure.RT Control Knob: Reset Time, is the time to wait for the relay to pull when the voltages return to norma.Protection FunctionsHigh Voltage Protection - To enter the error state: If the vo
