Auto-Tune Procedure 
The purpose of the auto-tune is to set PID parameters of temperature control loops. This function is used 
only if the regulation of a zone is not stable. Example: setpoint 120 and measure move from 110 to 
130°C. PID are adjusted in factory before departure of the oven. 
 WARNING!  Never perform the auto-tune if not necessary. 
 WARNING!  Before activating the auto-tune, read through the complete procedure. 
IMPROPER HANDLING COULD DAMAGE THE OVEN. Do not perform the 
auto-tune procedure while the oven is running in production. 
To set PID parameters of temperature control loops: 
1.  Click on the setpoint box of a zone (Figure 3-27).

2.  Click on REG Z1 to access the PID Loop Control (Figure 3-28).
