HAND TERMINAL
(HART)
This chapter serves as a supplement to the chapter Operating the positioner via the HART hand termi-
nal and contains only the information required for the process controller.
General information on the process controller, e.g. setting up a process control system or factory
settings, are to be found in the chapter Operating the process controller.
Configuration
For process control you need the supplementary function P-CONTROL.
Release the function by switching the function P-CONTROL to ON with the function key F2 in the
submenu Configuration under Item 1 - Add Function.
Configure P-CONTROL after release in the submenu Configuration - P-CONTROL.
You can either the function P.Q‘LIN with F3 - ABORT or start the function P.Q’LIN via the key
F4 - OK. As long as P.Q’LIN is running, the following message appears:
Running PQLIN
Running of the function P.Q’LIN is ended by an OK message.
Operating the process controller via the HART hand terminal
As soon as P-CONTROL has been activated via Add Function, two additional functions may be
selected: P.Q’LIN and PTUNE.
P.Q‘LIN
P.Q’LIN serves to linearize the process characteristic and may be started under Configuration or under
Main -
PQLIN.

ATTENTION!
All altered parameters are only stored in the RAM memory of the SIDE Control and
hence will no longer be present after a cold start. If you want to permanently store the
altered parameters, they must be saved via the menu item EEPROM Control in the
Main menu or in the menu Configuration - Save to EEPROM.
