Undervoltage knob (UNDR) Used to set from -30% to 30% of the rated input. Operating time knob (T) Used to set the operating time to 0.1 to 30 s.

Voltage input Outputs L1 L2 For a relay output, the SPDT contacts are output on terminals 11, 12, and 14. For a transistor output, the output is on terminals 11 and 14.

Setting Methods Overvoltage The overvoltage knob (OVER) is used to set the overvoltage threshold. The overvoltage can be set to between -30% and 30% of the rated input voltage. Turn the knob while there is an input to the input terminals until the alarm indicator flashes (when the set value and the input have reached the same level.) Use this as a guide to set the voltage. The rated input depends on the model and the DIP switch setting. Example: K8DT-PM1 with DIP Switch Set to 200 V The rated input is 200 VAC and the setting range is 140 to 250 V. Undervoltage Undervoltage is set using the undervoltage knob (UNDR). The undervoltage can be set to between -30% and 30% of the rated input. Turn the knob while there is an input to the input terminals until the alarm indicator flashes (when the set value and the input have reached the same level.) Use this as a guide to set the voltage. The rated input depends on the model and the rotary switch setting. Example: K8DT-PM1 with Rotary Switch Set to 200 V The rated input voltage is 200 VAC and the setting range is 140 to 250 V. Operating Time The operating time is set using the operating time knob (T). The operating time can be set to between 0.1 and 30 s. If the input exceeds (or drops lower than) the voltage set value, the alarm indicator will start flashing for the set period and then stay lit. 5 K8DT-PM Dimensions (Unit: mm) Three-phase Voltage and Phase-sequence Phase-loss Relays K8DT-PM1 K8DT-PM2 100 90 86 17.5 5 90 Options (Order Separately) Front Cover Y92A-D1A 1.8 52.7 3.5 17.5 5.85 Optional Parts for DIN Track Mounting DIN Tracks PFP-100N PFP-50N 7.30.15 4.5 350.3 15 25 10 25 25 1000(500) * 10 25 15(5) * 270.15 1 * Dimensions in parentheses are for the PFP-50N. 6 K8DT-PM Questions and Answers Q Q Checking Operation Overvoltage Gradually increase the input from 80% of the set value. The input will equal the operating value when the input exceeds the set value and the alarm indicator starts flashing. Operation can be checked by the relay output that will start after the operating time has passed. Undervoltage Gradually decrease the input from 120% of the set value and check the operation using the same method as for an overvoltage. How to Measure the Operating Time Overvoltage Change the input suddenly from 70% to 120% of the set value and measure the time until the Unit operates. Undervoltage Change the input suddenly from 120% to 70% of the set value and measure the time until the Unit operates. Operating Time Adjust the slide resistor so that the voltage applied to the K8DT terminals is 120% of the set value for overvoltage detection or 80% of the set value for undervoltage detection when the auxiliary relay in connection diagram 2 operates. Close the switch and use a cycle counter to measure the operating time.

Phase loss Create a phase loss for any input phase and check that the K8DT operates. 7 K8DT-PM Questions and Answers Q Q Load-side Phase Loss In principle, phase loss cannot be detected on the load side because the K8DT-PM measures three-phase voltage to determine phase loss. Q Motor Load Phase Loss during Operation Motor load phase loss cannot be detected during operation. It can be used to detect phase loss at startup. Normally, three-phase motors will continue to rotate even if one phase is open. The three-phase voltage will be induced at the motor terminals. The diagram shows voltage induction at the motor terminals when phase R has been lost with a load applied to a three-phase motor. The horizontal axis shows the motor load as a percentage of the rated load, and the vertical axis shows voltage as a percentage of the rated voltage. The lines in the graph show the voltage induced at the motor terminals for each load phase loss occurs during operation. As the graph shows, phase loss cannot be detected because the motor terminal voltage does not drop very much even if a phase is lost when the load on the motor is light. To detect motor load phase loss during operation, use the undervoltage detection function to detect the motor terminal voltages at phase loss. Set the operating time carefully because it will affect the time from when the phase loss occurs until tripping when this function is used. Characteristic Curve Diagram Voltage (as a percentage of rated voltage) Note: This characteristic curve shows the approximate values only. 100 95 VST 90 85 80 VTR 75 70 65 60 55 50 VRS 45 0 10 20 30 40 50 60 70 80 90 100 110 Motor load (as a percentage of rated load) Note: For phase loss of phase R. VST, VTR, and VRS indicate the motor terminal voltage at phase loss. 8 Is an overvoltage detected if only one of the three-phase phase-to-phase voltages exceeds the overvoltage set value? The K8DT monitors all three phase voltages. Therefore, an overvoltage is detected if only one of the phase-to-phase voltages exceeds the set value. The same is true for undervoltages.

Precautions for Correct Use Supplementary comments on what to do or avoid doing, to prevent failure to operate, malfunction, or undesirable effects on product performance. !WARNING Electrical shock may occasionally cause serious injury. Confirm that the input voltage is OFF before starting any wiring work and wire all connections correctly. !CAUTION Doing so may occasionally result in minor injury due to electric shock. Do not touch the Relay while the power supply is ON, except for the adjustment knob. There is a risk of minor electrical shock, fire, or device failure. Do not allow any pieces of metal, conductors, or cutting chips that occur during the installation process to enter the product. Meaning of Product Safety Symbols Used to warn of the risk of electric shock under specific conditions. Used for general prohibitions for which there is no specific symbol. Used to indicate prohibition when there is a risk of minor injury from electrical shock or other source if the product is disassembled. Used for general mandatory action precautions for which there is no specified symbol. Explosions may cause minor injuries. Do not use the product in locations with inflammable or explosive gases. There is a risk of minor electrical shock, fire, or device failure. Do not disassemble, modify, repair, or touch the inside of the product. Use of the product beyond its life may result in contact welding or burning. Make sure to consider the actual operating conditions and use the product within its rated load and electrical life count. The life of the output relay varies significantly with the switching capacity and switching conditions. If the Relay is used with incorrect wiring, fire may occasionally occur, possibly resulting in physical damage. Check the wiring for mistakes before you turn ON the power supply. If the Relay fails, monitoring and alarm outputs may fail to operate. This may result in physical damage to the facilities, equipment, or other devices that are connected to it. To reduce this risk, inspect the Relay regularly. To maintain safety in the event of malfunction of the Relay, take appropriate safety measures, such as installing a monitoring device on a separate line. If the wire insertion length is insufficient, fire may occasionally occur, possibly resulting in physical damage. Insert the wires all the way to the back. The terminal block may be damaged if you insert a flat-blade screwdriver in the release hole with excessive force. Insert the flat-blade screwdriver into the release holes with a force of 15 N or less. 9 K8DT-PM Precautions for Safe Use 29.To prevent wiring materials from smoking or igniting, confirm wire ratings and use the wiring materials given in the following table. 1.
