C (1): Degree Celsius F (5): Fahrenheit
IN1
IN2
Max. value of PV
input range Set the instrument input range (RL1 < RH1).
- For temperature input -
Set the range of temperature that is actually controlled.
- For voltage input -
Set the range of a voltage signal that is applied.
The scale across which the voltage signal is actually controlled
should be set using the parameters Maximum Value of PV Input
Scale (SH1) and Minimum Value of PV Input Scale (SL1).
Depends on
the PV
input type.

PV input decimal
point position
(shown when in
voltage-input mode) Set the position of the decimal point of voltage-mode PV input.
0 to 4
0: No decimal place
1: One decimal place, 2 to 4: Two, three, four decimal places Depends on

Selection of PV
input burnout action Allows the PV input value to be determined as shown below in
case of PV input burnout.
• 105% of PV input range if set to “Upscale”
• -5.0% of PV input range if set to “Downscale”
OFF (0): Disable
UP (1): Upscale
