USERGUIDE
n AUTOTUNING:
Auto tuning is a function whereby the controller
learns the process characteristics by itself and
automatically sets the required P,I and D values.
The auto-tuning function can be activated at any
time during the process after power ON , while
temperature is rising or when control has
stabilized. Autotune is indicated by T LED blinking
After the auto tuning procedures are completed,
the T LED will stop flashing and the unit will
revert to PID control by using its new PID values.
The PID values obtained are stored in the nonvolatile memory.
Initial setup for a new process
The set point is changed substanitally from the previous auto-tuning value.
The control result in unsatisfactory.
The following controller parameters are automatically adjusted by Auto- tune
according to the characteristics of the process:
Proportional Band (Pb-1)
Integral Time (It-1)
Derivative Time (dt-1)
Input Filter (FtC)
The auto-tuning is applied in cases of:
=
=
=
If the control performance by using auto-tuning is still unsatisfactory, the following rules
can be applied for further adjustment of PID values:

3.SENSORINPUTWIRING
TC - Thermocouple (J, K, T, R, S, C, E, B, N, L, U, W, Platinel II).
V - Voltage Input (0 to 10 V DC).
mA- Current Input (0 to 20mA DC)
RTD - PT100.
NOTE : 1) Refer input type selection in level 0 of programming menu.
2) For PID500 refer input jumper selection as in point no. 12 on page 6.
3) For 2 wire RTD short terminals 8 & 9 (for PID500) and terminals 3 & 4
(for PID110 & PID330) .
