Run Autotune - Omron E5CC Quick Start Instruction

OMRON

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.
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.
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.
