5. Entering and Checking the New Tuning Parameters

a)

The values required by the TDC4 for tuning are PRoP, RESt, and RAtE.

b)

Enter the values calculated above into the TDC4 by accessing the CNFG, OUt 1, CtRL menu.

c)

Set the controller back to Automatic Mode by changing SELF mode back to dSbL.

d)

Enter a setpoint that is 10 to 20

°

C above the current temperature.

e)

Rerun the "TDCTUNE.EXP" script. A smooth rise in temperature should be seen. A overshoot of
1 or 2

°

C is acceptable.
