OMRON Quick Start Instruction E5CC 1.3.2 Run Autotune For accurate controlling the correct PID parameters are important. These can be calculated by using the autotune function. 1. Using the up and down buttons, set the desired temperature (set value). 2. Press the 1st button briefly until l.adj is displayed 3. Then press the 2nd button until the at parameter is displayed. 4. Using the up button, select at-2 5. After a few seconds the tune message lights up. As long as this message is lit, the controller is learning the process to configure the correct parameters. 6. Then briefly press the 1st button again. The temperature will be displayed again and the tune message will remain lit. 7.
As long as the tune message is lit, the controller is tuning. During this process the temperature will vary. Do not interrupt the tuning process. When the message is no longer displayed, the parameters have been set correctly and controlling will be stable and economical. During tuning the temperature may rise above the set value. If this is not desirable, then you may also select at-1 . The controller will now commence tuning at 40% of its capacity, which will cause tuning to be slower and less excessive. Caution: Running autotune may take some time, depending on your process. To guarantee the correct settings, do not interrupt this process.
If autotune still has not completed after 2 hours, please contact the Omron help desk. 12
