K8AB-PM 7 setting method 1. overvoltage the overvoltage knob (over) is used to set the overvoltage threshold. the overvoltage can be set to between ? 30% and 25% 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 inpu t have reached the same level.) use this as a guide to set the voltage. the rated input depends on the model and dip switch setting. example: K8AB-PM1 with pin 2 turned off (three-phase, three- wire mode) and pins 3 and 4 turned off (rated voltage of 200 v) the rated input voltage is 200 vac and the setting range is 140 to 250 v. 2. undervoltage undervoltage is set using the undervoltage knob (under). the undervoltage can be set to between ? 30% and 25% 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 inpu t have reached the same level.) use this as a guide to set the voltage. the rated input depends on the model and dip switch setting. example: K8AB-PM1 with pin 2 turned off (three-phase, three- wire mode) and pins 3 and 4 turned off (rated voltage of 200 v) the rated input voltage is 200 vac and the setting range is 140 to 250 v. 3. operating time the operating time is set usin g the operating time knob (t). the operating time can be set to between 0.1 and 30 s. turn the knob while there is an input to the input terminals until the alarm indicator flashes (when the set value and the inpu t have reached the same level.) use this as a guide to set the operating time. if the input exceeds (or drops lower than) the voltage setting, the alarm indicator will start flashing for the set period and then stay lit. dimensions (unit: mm) three-phase voltage with phase-sequence, phase-loss relays 22.5 100 72 90 5 5 K8AB-PM1 K8AB-PM2
K8AB-PM 8 checking operation overvoltages gradually increase the input from 80% of the setting. the input value will equal the operating value when the input exceeds the setting 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 setting and check the operation using the same method as for overvoltage. example: for monitoring mode set to three-phase three-wire monitoring, a rated voltage of 200 v, and an operating time of 5 s. note: K8AB-PM @ output relays are normally operative. connection diagram 1 how to measure the operating time overvoltage change the input suddenly from 0% to 120% of the set value and measure the time until the unit operates. undervoltage change the input suddenly from 120% to 0% 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 k8ab terminals is 120% of the set value (for overvoltage detection) and 80% of the set value (for undervoltage detection) when the auxiliary relay operates, as shown in connection diagram 2. close t he switch and use the cycle counter to measure the operating time. connection diagram 2 checking the phase sequence and phase loss operation phase sequence switch the wiring, as shown by the dotted lines in connection diagram 1, to reverse the phase sequence and check that the k8ab operates. phase loss create a phase loss for any input phase and check that the k8ab operates. operating adjustment knobs use a screwdriver to turn the knobs. there is a stopper to prevent the knob from turning any further once it has been turned completely to the left or right. do not force the knob past these limits. questions and answers q operating set value input voltage alarm indicator relay output flashing lit 5 s 0 to 150 v v1 three-phase variable autotransformer overvoltage undervoltage l1 l2 l3 3 , 200 vac v2 v3 l1 l2 l3 q 3 , 200 vac l1 l2 l3 c 200 v cycle counter v1 v2 v3 x x/a x/b l1 l2 l3 r1 r2 r1: slide resistor 200 ? 200 w r2: 100 ? 400 w q q
K8AB-PM 9 load-side phase loss in principle, phase loss cannot be detected on the load side because the K8AB-PM @ measures three-phase voltage to determine phase loss. 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 note: for phase loss of phase r. v st , v tr , and v rs indicate the motor terminal voltage at phase loss. overvoltage detection when only one phase exceeds the overvoltage threshold the K8AB-PM @ monitors each of the three-phase voltages. this means an overvoltage is detected if even only one phase exceeds the threshold value. the same applies to undervoltages. questions and answers q q 100 95 90 85 80 75 70 65 60 55 50 45 10 0 2030405060708090100110 v st v tr v rs note: this characteristic curve shows the approximate values only. voltage (as a percentage of rated voltage) motor load (as a percentage of rated load) q in the interest of product improvement, specif ications are subject to change without notice. all dimensions shown are in millimeters. to convert millimeters into inches, multiply by 0.03 937. to convert grams into ounces, multiply by 0.03527.
