● Transfer Output
Scaling
5-48
• Scaling of the output value can be performed using Transfer Output
Upper Limit and Transfer Output Lower Limit parameters. The upper-
limit can be set to a smaller value than the lower limit to perform
reverse scaling. The scale can be enlarged using the width between
the upper and lower limits specified in the parameters. The following
diagram shows an example of scaling the heating MV.

• If the Input Type, Scaling Input Value 1 or 2, SP Upper and Lower
Limit, or Temperature Unit parameter is changed, the Transfer
Output Upper Limit and Transfer Output Lower Limit parameters will
be returned to the upper and lower limits of the setting range.
• If an input error occurs when the transfer output assignment is set to
"PV," the transfer output changes to the upper limit and it changes to
the lower limit for reverse scaling.
