8. Auto Tune Metod
Auto Tune method is used for determining PID parameters used by the device.
Starting Auto Tune (Limit Cycle Tuning) Operation by the user :
• Adjust t
emperature control on/off or PID parameter (
• Adjust auto tune selection parameter (
• "T" led is activated and auto tune process is started.
If Auto Tune operation is finished without any problem, the device saves the new PID coefficients,
calculated using the previously found "T" and "B" values, to memory and continue to run.
parameter is adjusted
Cancelling Auto Tune (Limit Cycle Tuning) operation :
1 - If sensor breaks;
2 - If auto tune operation can not be completed in 8 hours ;
3 - If user adjusts
parameter
4- During auto tune operation if the user changes the temperature control from pid to on/off;
5 - If process set value is changed while auto tune operation is being performed;
Auto tune is canceled. "T" led becomes inactive. Then, without doing any changes in PID
parameters, device continues to run with previous PID parameters.
