7 / 10 page 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 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. 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.)
