(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.

NO USE 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 input 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. 7 K8AB-AS 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 input have reached the same level.) Use this as a guide to set the hysteresis. Example: Maximum of 200 A AC, Current Setting (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 input 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 indicator will start flashing for the set period and then stay lit. 4. Startup Lock Time Inrush current 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. Current setting 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 startup lock time. 30% of current setting The startup lock time will start when the input current reaches 30% or more of the current Startup lock time setting. There are no outputs Use startup lock time to prevent unwanted operation, e.g., as a result of inrush current. Startup lock timer start during this period.

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 Mode, Normally Open Relay Drive, and an Operating Time of 5 s Set value Current input 5s Relay output Connection Diagram A 100 VAC 0 to 10 A 30 400 W (two in parallel) Output Input terminals Power supply Variable autotransformer 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. Q 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 K8ACCT200L 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. Lit Flashing Alarm indicator Operating Adjustment Knobs A1 A2 Motor current (percentage of rated value) Q 500% 100% Several seconds to several tens of seconds Time from beginning of startup 100 VAC C 100 V Cycle counter Q 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 continuous 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. 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. Primary-side conductor To the K8AB-AS3 K8AC-CT200L 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 Q Monitoring Switch-mode Power Supplies Switch-mode Power Supplies cannot be monitored. In circuits with a capacitor input, 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. K8AB settings: Overcurrent detection, operating 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. 9 K8AB-AS 10 K8AB-AS 11 Warranty and Application Considerations Read and Understand this Catalog Please read and understand this catalog before purchasing the products.
