Press on the "Up Key" and enter your temperature set point less than 80ºC
5.
The OUT indicator will lit and the heating process will start
Remarks: Don’t change parameters on the controller except from your
temperature set point
Auto-tuning
The auto-tuning process is performed at set point.
The process will oscillate around the set point during tuning process. Set a set point to
a lower value if overshooting beyond the normal process value is likely to cause
damage.
The auto-tuning is applied in cases of:
Initial setup for a new process
The set point is changed substantially from the previous auto-tuning value
The control result is unsatisfactory
Operation :
1.
Verify that the LOCK parameter is NONE.
2.
To verify this, press
and hold the "SCROLL KEY" until SET
appears on the
display.
3.
Press on the "SCROLL KEY" once and change the LOCK value to NONE
with the "UP KEY"
4.
Press once on the "EXIT KEY"
5.
Enter your temperature setpoint with the "UP KEY"
6.
Press and hold the "SCROLL KEY" until "A-T" appears on the display.
7.
Press again for at least 5 seconds on the SCROLL KEY , The AT indicator
will begin to flash and the auto-tuning procedure is beginning.
8.

Procedures:
After the auto-tuning procedures are completed, the AT indicator will cease to flash
and the unit revert to PID control by using its new PID values. The PID values
obtained are stored in the nonvolatile memory.
