IF
If Ar Parameter is entered from 0 to Scale High Point , this value is
used forAnti-Reset Windup.
If Ar Parameter is selected , heating proportional band is used
for heating PID process instead of Ar Parameter and cooling
proportional band is used for cooling PID process instead of Ar
Parameter.
While PID operation is running if
condition is true,
integral value is calculated. If the condition is not true , integral value is
not calculated and last calculated integral value is used.
- <= process value <= +
Scale High Point : Maximum process input value in Pt-100 and Tc
inputs , 9999 for fixed dual point calibration used inputs , Scale high
point is the biggest one from or for selectable dual point
calibration used inputs , Scale high point is the biggest one from
or for multi point calibration used inputs.
Note: Point position changes according to process input type and
scale , Unit changes according to the selection in this
parameter.
Note: Point position changes according to process input type and
scale , Unit changes according to the selection in this
parameter.
+ is used as set value in PID calculations. It is used for
shifting the proportional band.

Example: If = 500 = 5 = -5°C , °C or °C , shifting
of the proportional band is shown below :
