K8AB-AS 7 operation and setting methods setting ranges and wiring connections note: 1. the dc input terminals have no polarity. 2. the K8AB-AS3 is designed to be used in combination with the omron k8ac-ct200l current transformer (ct). (direct input is not possible.) connections 1. input connect the input between the i1-com, i2-com, or i3-com terminals, according to the input current. malfunctions may occur if the input is connected to unused terminals and the unit will not operate correctly. terminal i1 is not used by the K8AB-AS3. if using the omron k8ac-ct200l ct, connect to terminals k and l on the k8ac-ct200l. (terminals kt and lt are not used.) 2. power supply connect the power supply to terminals a1 and a2. 3. outputs spdt relays are output to terminals 11, 12, and 14. note: use the recommended ferrules if using twisted wires. dip switch settings the resetting method, relay drive method, and operating mode are set using the dip switch located on the bottom of the unit. K8AB-AS @ does not use sw1. setting method 1. setting current the current knob (sv) is used to set the current. the current can be set to 10% to 100% of the maximum measuring current. 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 current. the maximum measuring current will differ depending on the model and the input terminal. example: K8AB-AS3 using input terminals i3-com the maximum measuring current will be 200 a ac and the setting range will be 20 to 200 a. model measuring current wiring connection K8AB-AS1 2 to 20 ma ac/dc i1-com 10 to 100 ma ac/dc i2-com 50 to 500 ma ac/dc i3-com K8AB-AS2 0.1 to 1 a ac/dc i1-com 0.5 to 5 a ac/dc i2-com 0.8 to 8 a ac/dc i3-com K8AB-AS3 10 to 100 a ac (see note 2.) i2-com 20 to 200 a ac (see note 2.) i3-com K8AB-AS3> k l load current input signal output k8ac- ct200l 14 12 a1 a2 i1 i2 i3 11 relay signal output com K8AB-AS3 single-phase power power supply voltage on off sw1 sw2 sw3 sw4 dip switch dip switch functions note: all pins are set to off at the factory. switch on off ? resetting method automatic reset --- --- no use manual reset --- --- ? relay drive method normally closed --- --- normally open --- ? --- operating mode undercurrent --- --- overcurrent ? --- --- on off 4 3 2 1
K8AB-AS 8 2. hysteresis hysteresis is set using the hysteresis knob (hys.) the setting range is 5 to 50% of the operating value. 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 hysteresis. example: maximum of 200 a ac, current setti ng (sv) of 50%, and overcurrent operation operation will be at 100 a and resetting at 90 a when the hysteresis (hys.) is set to 10%. 3. 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. 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 current exceeds (drops lower than) the current setting, the alarm indica tor will start flashing for the set period and then stay lit. 4. startup lock time the startup lock time is set using the startup lock time knob (lock). the startup lock time can be set to between 0 and 30 s. turn the knob while there is an input to the i nput 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 startup lock time. the startup lock time will start when the inpu t current reaches 30% or more of the current setting. use startup lock time to prevent unwanted operation, e.g., as a result of inrush current. dimensions (unit: mm) single-phase current relays omron ct inrush current current setting 30% of current setting startup lock timer start startup lock time there are no outputs during this period. 22.5 100 72 90 5 5 K8AB-AS1 K8AB-AS2 K8AB-AS3 1.8 76 4.1 10 10 5.9 5.2 20 two m5 screw holes or two 5.5-dia. holes 57 30 dia. 14.5 14.5 6 8.5 50 33.5 34.5 81.5 13.5 86 54 63 11 4.7 four m4 6 screws 17 20 9.3 1.7 1.7 9.3 76 mounting hole dimensions note: the omron current transformer (ct) is designed to be used with the K8AB-AS3. use terminals k and l for connections.

K8AB-AS 9 checking operation overcurrents gradually increase the input from 80% of the setting. the input will equal the operating value when the input exceeds the setting and the alarm indicator starts flashing. operation can be checked by the relay outputs that will start after the operating time has passed. undercurrent gradually decrease the input from 120% of the setting and check the operation using the same method as for overcurrent. example: overcurrent operating mo de, normally open relay drive, and an operating time of 5 s connection diagram how to measure the operating time overcurrent change the input suddenly from 0% to 120% of the set value and measure the time until the unit operates. undercurrent change the input suddenly from 120% to 0% of the set value and measure the time until the unit operates. monitoring switch-mode power supplies switch-mode power supplies cannot be monitored. in circuits with a capacitor i nput, including switch-mode power supplies, the input capacitor recharge current flows in pulse form as the load current. the K8AB-AS @ has a built-in filter as a countermeasure against high frequencies and cannot be used to remove pulse current. 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. can a motor with a rated current of 5 a be monitored using the k8ab? are there any application precautions? the K8AB-AS1 and K8AB-AS2 cannot be used with motor loads. use the K8AB-AS3 in combination with the k8ac- ct200l current transformer (ct). with motor loads, the startup current and stall current will cause a current of many times the rated current to flow. refer to the following figure for information on the motor startup current. for a motor with a rating of 5 a, the startup current will be approximately 30 a. the startup current will exceed the overload capacity (rating: 150% for 1 s) of the K8AB-AS1 and K8AB-AS2 and result in failure of the relay. to monitor the motor load, use the K8AB-AS3. (overload capacity: 120% of rating for c ontinuous load, 200% of rating for 30 s, and 600% of rating for 1 s). the K8AB-AS3 has a large input range. pass the conductors multiple times through the special ct. concept behind passing conductor through the ct when using the K8AB-AS3 example: monitoring overload of a motor with a rated current of 5 a k8ab settings: overcurrent detection, operati ng value setting: 25%, operating time: 0.1 s startup lock timer: 0.1 to 30 s (set the timer according to the duration of the startup current.) the setting range for the K8AB-AS3 is 10% to 100% of the rated current (i.e., 10 to 100 a). pass the conductors through the ct five times so that at least 10 a of current flows. the input current to the k8ab will be 25 a (i.e., 5 a x 5 loops). if a startup current of six times the rated current is generated, it will be 150 a (i.e., 25 a x 6). the overload capacity for the K8AB-AS3 is 200% of the rating for 30 s. the relay will not fail even if the startup current continues for 30 s, and it is possible to perform overload detection. questions and answers q set value current input alarm indicator relay output flashing lit 5 s 100 vac 100 vac 30 ? 0 to 10 a a a1 a2 c 100 v variable autotransformer input terminals power supply output cycle counter 400 w (two in parallel) q q q q motor current (percentage of rated value) several seconds to several tens of seconds time from beginning of startup 100% 500% k8ac-ct200l primary-side conducto r to the K8AB-AS3 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.
