Chapter 4 Parameter settings and functions
41
If heating and cooling control is used, set the heating and cooling
control cycles separately.
Deviation correction / manual reset setting
When only proportional control (P, PD control) is used, the heat capacity of the control
object and the heat capacity of the heater affect the heating and cooling time. Therefore,
there may be a certain deviation in the final control temperature, which can be corrected
manually.
Manual reset adjustment based on control results
Set the deviation to 50% for stable control
The deviation is 50% when PV=SV; the deviation exceeds 50% when PV<SV; the
deviation is less than 50% when PV>SV.
The deviation function can only be used in proportional control. If
the integration time is set to 0, the manual correction parameter
value can be modified.
Manual adjustment cannot be set during heating and cooling
control, the parameter is automatically set to 0%
Only applicable integration time is set to 0 (only in P or PD control)
Automatically change to standard control (P, PD control) when
switching heating and cooling control is 50%
4.3.4 Self-tuning
During PID control, the required PID value is automatically adjusted according to the
thermal characteristics and response speed of the control object, so that the product can
respond quickly and accurately control the temperature.
Auto-tuning ON/OFF setting
The PID value is automatically saved after the auto-tuning is completed, and the user can
also set the PID value according to the usage environment.
