4.3 System Operation Controls
The Millenium HX system is controlled by a Programmable Logic Controller (OPLC) with
an integrated operating panel that sends and receives signals to and from various
components and sensors in the system. The user can set and view different parameters
on the Human Machine Interface (HMI) display on the front of the RO. In this section,
an overview of the operation of the OPLC controller is provided to help the user gain
familiarity with the RO and basic system parameters.
MAIN SCREEN
Refer to Figure 1, from this screen, the operator can press RUN,
SETTINGS, LOGS or PRESS AND HOLD FOR CLEANING MODES. If
the RO is set to display in metric units, the letter M will be visible
in the upper right hand corner of the screen.
In addition, this screen displays the current date, time and
date/time of the Last Completed Heat Process. This could
represent a Storage Heat or Single Heat disinfection.
The current date and time may be adjusted by pressing the area of
the time and date and following the on screen instructions to
