7.1 Setting Functions of PV Input
7.1.1 Setting Input Type, Unit, Range, Scale, and Decimal Point Position
Description
The figure below describes the case of PV input.
Example of Temperature 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.
PV input range
Example of Voltage and Current Inputs
The figure below is an example of setting 2-4 V DC and a scale of 0.0 to 50.0 m³/h.
Minimum value of PV input scale
1 V 5 V (input signal)
SL = 0.0 m³/h SH = 50.0 m³/h
Maximum value of PV input scale
2 V 4 V
RL = 2.000
RL = 1.000
RH = 4.000
RH = 5.000
PV input scale
Input type
Set a range to be
controlled.
PV input range
When using 1-5 V DC signal as is, set RH = 5.000 V, RL = 1.000 V, SDP=1, and SH =
50.0, and SL=0.0.
