Thank you for choosing a NIVELCO instrument.
We are sure that you will be satisfied throughout its use.
1. APPLICATION
The UNICONT PMM-300 series is a universal display and controller. It can also be used as (one
or two channel) display and limit-switch depending on the configuration of the instrument. For the
complete range of the models, technical data and programming in detail see the INSTALLATION
AND PROGRAMMING MANUAL.
The aim of this User’s Manual is to give a concise guideline for applications of the UNICONT
PMM as a process display and limit switch.

5. PUTTING INTO OPERATION
The Steps of putting into operation are:
-
wiring
-
switching on the instrument
-
setting
Factory
Default
(if
necessary)
The PMM is delivered with (temperature
control oriented) Factory Default A. Therefore
you have to change over to Factory Default B
(See Triple Push-Button Operation)
-
changing parameters and Electronic Dip
Switch (EDS) position (if necessary)
Programming will be carried out by the push-
buttons on the front panel (see Point 6.)
The
programming
flow
chart
and
the
Menu/Submenu points are shown in Point 7.
The Submenu points with grey background are
not used in
applications as indicator and limit-
switch.
-
With instruments with one input only, the
lower (green) row will not be used as display
but only for entering the values to be
programmed.
