Xiamen Yudian AI series intelligent PID thermostat self-tuning steps

The new table of Yudian thermostat must be self-tuned once before the new system is used. The instrument also has an adaptive self-learning function. After the setting is completed, the instrument must be operated for tens of minutes to several hours to enter the optimal working state. Why is it unstable?

A: The new watch must be self-tuned once before the new system is used. The instrument also has an adaptive self-learning function. After the tuning is completed, the instrument needs to work for tens of minutes to several hours to enter the optimal working state. If the control has deviation after setting Generally, the self-tuning conditions do not match. You can refer to the instructions on the manual to modify the self-tuning conditions. In special circumstances, you may need to manually modify the PID or MPT parameters. For the same system (for example, the same type of electric furnace), the characteristics are generally not much different. You can directly enter the known correct PID or MPT parameters without repeating the auto-tuning.



Xiamen Yudian AI series intelligent temperature controller self-tuning steps

(Newly put into operation, the temperature must be self-tuning, which plays a vital role in the control effect of the instrument)

● The instrument is installed at the use site, and the parameter settings (instrument input/output specifications, etc.) are correct, and the menu parameter setting interface is exited.

● Ensure that the measured temperature (PV value) is room temperature (if the resistance furnace temperature has been heated to a high temperature, the heating power can be turned off to lower the resistance furnace temperature to room temperature)

● Use the SV value of the modified window on the main screen of the meter to set it to about 50% to 80% of the target temperature. (For example, if you need to control it at 200 degrees, set it to any one of 100 to 160 °C.

● Exit to the meter main measurement screen to ensure that the temperature measurement signal and the heating part are wired normally. Press and hold the left button for 2 seconds (if the self-tuning has been done before, this method is invalid, to start the auto-tuning, you must enter the parameter menu, change CtrL to 2), then the meter displays

The window will flash to display the word “At” and the set temperature, indicating that the meter has entered the auto-tuning state.

● The meter will perform position adjustment for about 2 cycles. When the SV window stops flashing At, the instrument self-tuning ends.

● After the auto-tuning is finished, set the set value according to actual needs.
