Section 5 Parameters
IS mode (1) Manual reset value
•
This function resets the offset that occurs when P (or PD) control is used.
The offset that occurs is set in °C or °F as the manual reset value. (This
applies when manual reset is enabled.)
Function
• This parameter is displayed only when control mode switch 4 is ON. Even
when the switch is OFF, the manual reset function remains enabled.
Setting
* The set value H is a positive value, and L is a negative value.
* The decimal position is set automatically by the selected Sensor.
IS mode (2) AT execute/cancel
This parameter is used to start AT (auto-tuning). (This parameter is displayed only when no PV
display is set for the PV/SP display.)
When the PV display is enabled, AT is executed when the U and D Keys are pressed
simultaneously for at least 2 s while the PV is displayed.
• The MV is forcibly increased and decreased around the set point to find the
characteristics of the control target. From the results, the PID constants are
automatically set in the "proportional band" (P), "integral time" (I), and
Function
"derivative time" (D) parameters.
