CAUTION

When using the maintenance port, do not supply power to the indicator. Otherwise, the indicator does not work normally.

If power is supplied to the indicator while the cable is connected, or the cable is connected to the indicator already turned on, unplug the cable and turn on the indicator again. The indicator returns to the normal condition.

Engineering Units

Input range (scale): the PV range low limit is set to 0%, and the high limit is set to 100% for conversion.

Input range (scale) span: the PV range span is set to 100% for conversion.

In this manual, the parameter setting range is described as the “input range” and “input range span.” This means that engineering units are required to be set. Set a temperature for temperature input.

The following describes a conversion example.

When the PV input range is 100 to 600°C, 0% of the PV range is equivalent to 100°C, 50% of the PV range is equivalent to 350°C, and 100% of the PV range is equivalent to 600°C.

100% of the PV range span is equivalent to 500°C. 20% of the PV range span is equivalent to 100°C.
