This is the CFM Monitor screen. It
displays the Process CFM and the Cool
down CFM. The Process CFM is
measured by a differential pressure
transducer across the inlet and the outlet of
the process blower. Since the Cool down
CFM is set with a mechanical orifice, it is
a fixed percentage of the measured process
reading. The CFM Monitor option must
be installed (see screen 75, page 4-28,
also see note on this page) for this to
appear
This screen shows if the aftercooler is
enabled. If the aftercooler is disabled,

flow control option must be installed (see
screen 75, page 4-28, also see note on
this page) for this to appear
This screen shows if the control is opening
