FUZZY Mode: 

This comprises 2 parts: PID parameters and Fuzzy exclusive parameters. Since Fuzzy control is calculated based

on P.I.D values of PID control, the user must first set P.I.D parameters or perform auto tuning (AT) to produce these parameters. In
addition, Fuzzy control includes the following 2 exclusive parameters.
a

  Fuzzy Gain Setting: altering this value will directly affect the calculation of Fuzzy gain. Increasing this value will directly

enhance the Fuzzy control; decreasing this value will weaken the Fuzzy control. It is recommended that this value shall be 
decreased for systems with slow reaction to heating/cooling. This value may be increased for systems with quick reaction to 
heating/ cooling.   

b

  Set Fuzzy DeadBand: The effective bandwidth of Fuzzy control, when PV value enters into the range of SV-FZDB 

<PV<SV+FZDB, Fuzzy control will stop calculation. I.e., when the PV is within this temperature range, its Fuzzy control is 
fixed.

 Setting of multiple PID sets

When PID control is selected, the system provides 6 sets (PID 0~5) PID parameter sets (P, I, D and IOF parameter) to be selected by the 
user. In general conditions, one set of PID (P0) is adequate. For different setting values (SV), when the same PID value is not adequate 
to control the precision, the user may set up multiple sets of PID parameters for the system to automatically switch-over to an applicable 
PID set.   

Set only one PID set:

Set parameter 

  to 0 (PID 0, the first set) in

Regulation Mode

, set parameter 

  to ON; at this time, the System starts to

Auto Fine-tune the PID value. During the calculation, AT LED lights up in the display panel. When the PV value generates 2 curves of
temperature oscillation based on the SV value, the AT process is completed and the AT LED in the panel goes out. The calculated PID
parameters are displayed in 

  and 

, of which their content can be revised by the user.

Automatic switching-over Multiple PID sets:

Set parameter 

  to 0 (PID 0, the first set) in

Regulation Mode

, set the required SV value (e.g. 100 degree), set parameter

as ON; on completion of auto fine-tuning, the system fills in parameters 

  =100, 

  and

automatically, their content can be revised by the user.
Set parameter 

  to 1 (PID 1, the second set), set the required SV value (e.g. 150 degree), set parameter 

  as ON; on 

completion of auto fine-tuning, the system fills in parameters 

  =150, 

  and 

  automatically. 

Set parameter 

  to AUTO, System will verify on its own whether the current SV value is closer to parameter 

  or 

and load the corresponding PID set automatically. E.g., if SV=110, system will load 

  parameters. If SV=140, system will load 

  parameters. 

If more SV groups are required, PID2~PID5 can be set up with the same sequence as described above. 

 Tune Function 

This machine provides 2 tuning methods (Auto_Tuning and Self_Tuning) for automatic generation of PID parameters (only applicable 
when control mode is set to PID control). 

Auto_Tuning:  by  full  output  of  heating  or  cooling,  temperature  is  allowed  to  oscillate  up  and  down.  Attain  parameters  of  the
magnitude and period, calculate P, I, D, IOF parameters; in addition, save the temperature setting value for performing AT, for the
use of PID control. After Auto_Tuning, PID control will be carried out automatically.

Set parameter

AT setting: Set parameter

Self_Tuning: By full output of heating or cooling, max. slope of temperature alteration and system delay can be attained from the
Temperature-Time Curve, and P, I, D, IOF parameters can be calculated. Self tuning can be carried out in RUN mode and in STOP
mode.  In  the  RUN  mode,  PID  parameters  are  allowed  to  be  updated  when  the  machine  is  running;  in  the  STOP  mode,  PID
parameters for the SV value can be attained.
