8. Self Tune Method
Self Tune method is used for determining PID parameters used by the device.
Starting Self Tune (Step Response Tuning) Operation by the user :
• Adjust temperature control on/off or PID parameter
• Adjust self tune selection parameter (
• "Tune" and temperature are displayed alternately on the main operation screen.
In this way the Self-Tune process will be started
If Self Tune operation is finished without any problem, the device saves the new
PID coefficients to memory and continue to run.
parameter is adjusted
Not: The temperature value read from the sensor must be less than 5% of the process set
value in order to start the self tune operation.
Cancelling Self Tune(Step Response Tuning) operation :
1 - If sensor breaks;
2 - If auto tune operation can not be completed in 8 hours ;
3 - If user adjusts
4- During self tune operation if the user changes the temperature control from pid to on/off;
5 - If process set value is changed while self tune operation is being performed;
Self tune is canceled. "Tune" is not displayed. Then, without doing any changes in PID
parameters, device continues to run with previous PID parameters.
