3. Auto-Tuning
By simply pressing a single button, the built-in artificial intelligent is activated to automatically
calculate and set parameters ( P, I, d, SF, Bb, Ot ) that fit the condition to be controlled.
Figure 41
a) How to sart5and stop the auto-tuning process:
i. To activate auto-tuning, press and hold (>) until “AT” indicator blinks, which indicates autotuning
is in progress. When auto-tuning finishes, the “AT” indicator light turns off. Now newly
calculated PID parameters are stored in memory and will be used by the controller.
ii. To EXIT during the auto-tuning process, press and hold (>) until “AT” indicator turns off.
The previously entered PID parameters values are used by the controller.

5. Device Application Example
Figure 9
User wants to control internal temperature (T) of boiler by measuring the surface temperature of the
boiler. A surface mounted, Type K thermocouple is chosen. Boiler surface is to be maintained at 225
deg F. System power supply is AC120V. Installation opening is 44 x 20(mm). A solid state relay
(SSR) with a rating of 25A will be used to control the heating element.
a) Choose XMT-7100 with input from a Type T thermocouple.
b) See Figure 8 for connection diagram.
c) Parameter settings:
(Inty) = t
(Outy) = 2
(CAty) = 0
(PSb) = 0
(Rd) = 1
(CorF) = 1
(filt) = 0
(auto-tuning will be used to set PID parameters)
(SV) = 225 deg F
(AH1) = 325 deg F
(AL1) = 325 deg F
Power up the controller and press (>) to activate auto-tuning. When “AT” stops blinking, new PID
parameters are generated for the system. The controller is in normal operation mode.
