7.1.1 SettingInputType,Unit,Range,Scale,andDecimalPointPosition
Description
ThefigurebelowdescribesthecaseofPVinput.Theremoteinput
andauxiliaryanalog
input can be set in the same way.
ExampleofT
emperatureInput
The figure below is an example of setting Type K thermocouple and a measurement
range of 0.0 to 800.0 ºC.
Minimum value of PV input range
Input type
-270.0°C
1370.0°C
RL = 0.0°C RH = 800.0°C
Maximum value of PV input range
Set a range to be
controlled.
