Set-up procedure - 1st level
The 1st level of the set-up procedure allows the operator to modify , if required, the configuration of the following
parameters:
− tuning constant of the PID algorithm
− internal/externalPt100 reference sensor
− cooling rate
− °C/°F selection
− default parameters
− security code (n. 2 as a standard)
To enter this procedure start from the normal operating function and from the following indication:
•
press simultaneously < > + <F> keys to enter the 1st level of the set-up procedure and to obtain the following
indication relevant to the Proportional Band constant:
The PID constants are experimentally defined and memory loaded for tuning optimization.
The operator can eventually change the value for special applications only.
It is recommended for routine applications to use the "default" stored values
To adjust a new value use < > and < > cursors and memory store with the <E> key.
•
Press the <F> key to obtain the following indication relevant to the Integral constant:
•
Press the <F> key to obtain the following indication relevant to the Derivative constant:
•
Press the <F> key to select the Internal or External reference resistance thermometer (Pt100):
•
Press the <F> key to select the required temperature unit:
