K8AB-VS

Setting Method

1. Setting Voltage

The voltage knob (SV) 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-VS3 Using Input Terminal V3-COM

The maximum measuring voltage will be 600 VAC/VDC and the setting range will be 60 to 600 V.

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 setting and the input have reached the

same level.)

Use this as a guide to set the hysteresis.

Example: Maximum Setting of 600 VAC/VDC, Voltage Setting (SV) of 50%, and Overvoltage Operation

Operation will be at 300 V and resetting at 270 V 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 voltage exceeds (or drops lower than) the voltage setting, the alarm indicator will start flashing for the set period and then stay lit.
