Setting Voltage The voltage knob (AL1 and AL2) is used to set the voltage. The voltage can be set to 10% to 100% of the maximum measuring 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 maximum measuring voltage will differ depending on the model and the input terminal. Example:K8AB-VW3 Using Input Terminal V3-COM The maximum measuring voltage will be 600 V AC/DC and the setting range will be 60 to 600 V. 2. 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 exceeds (or drops lower than) the voltage setting, the alarm indicator will start flashing for the set period and then stay lit.

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. Undervoltage Gradually decrease the input from 120% of the setting and check the operation using the same method as for overvoltage. Example: Overvoltage Operating Mode, Undervoltage Operating Mode and an Operating Time of 5 s Note: K8AB-VW@ output relays are normally operative. 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. Q Setting the Pre-alarm Monitoring Mode Use the DIP switch to set the operating mode pins both to overvoltage (SW3 ON and SW4 OFF) or both to undervoltage (SW3 OFF and SW4 ON). Example: Both Pins Set to Overvoltage AL1 can be used as the pre-alarm for AL2 by setting a smaller voltage set value for AL1 than for AL2.
