The main (default) screens (Figure A.6) show the
pertinent system measurements as well as unit
sequence information.
The pertinent system measurements include
Vacuum Level. Pressing pertinent system data
buttons shows Trend information for that value.
Unit Sequence information shows all system
units.
• If the unit is running, that color bar shows
green and the adjoining symbol shows “*” for
across the line (full speed).
• If a unit is available and not running, that
color bar shows blue and the adjoining
symbol shows “+” if that unit is next to start.
• If a unit is not running and in purge mode, it
will display the symbol “^”.
• If the unit is unavailable and not running, that
color bar shows dark grey and the adjoining
symbol shows “X”. If the unit is in Manual and
not running, the color bar shows red and the
adjoining symbol shows “X”.
• If a unit is shutdown, that color bar shows
red and the adjoining symbol shows “!”
• If a unit is unavailable because it is in Manual
mode and it is running, that color bar shows

• If the unit is unavailable because the unit
cannot be reached via Ethernet, that color

symbol shows “?”.
A.2.5 5.7” Trend Screen
The trend screen (Figure A.7) shows the
measured value over a speci
fi
c time period:
• The default time period when opening the
window is the last 60 minutes. For a given
period, the maximum amount of data stored
will only be for the most recent time period
and the older data will be removed from view
and memory.
• Another time period is selected by pressing
the buttons at the bottom of the window.
These periods are 60 minutes (240 data
points – 0.25 min resolution), 4 hours (240
data points – 1 min resolution), 24 hours (240
data points – 6 min resolution) and 6 days
(240 data points – 0.6 hour resolution).

The service screen (Figure A.8) allows the
selection of various sub screens along with the
