Parameter Functions & Definitions 5-35

Upper-Limit Temperature Input Shift Value,

Lower-Limit Temperature Input Shift Value

Conditions of Use: The Input Type parameter must be configured for a

thermocouple on RTD sensor and the Input Shift Type parameter must be

configured for 2-Point Shift. When using an infrared type sensor simply

configure Input Type to infrared and Upper/Limit Input Shift is automatically

allowed.

Function: Whereas the entire input range is shifted by a fixed value (1-point

shift) in the Temperature Input Shift parameter, this function shifts the input

range by two points (2-point shift) at the Upper- and Lower-Limits. This

allows a more accurate offset of the input range.

This parameter sets input shift values for each of the Upper- and Lower-Limits

(2-point shift) of the input range are shown in Table 5.AL , Allowable Range.

Proportional Band,

Integral Time,

Derivative Time

Conditions of Use: The control method must be 2-PID control.

Function: These three parameters allow you to manually configure the PID

value parameters. Note that the PID parameters are automatically configured

by the controller when either the Auto-Tune (AT) or Self-Tune (ST)

parameters are executed.
