Figure 14, View Compressor Input/Output Status
Pressing the I/O button adjacent to the compressor on the VIEW-MENU screen
will access the screen shown in Figure 14. It is superimposed on the right side of
the Detail View Screen. It gives the status of the
compressor
digital inputs and
outputs. Many of these I/Os also appear in the Compressor State screen since
they are part of the start up sequence and define the compressor state at any
given time. Magnitude units will have two of any compressor screen.
A COMP button will appear in the lower left-hand corner of the Detail View
Screen. This button will toggle compressor data from #1 compressor to #2
compressor.
Figure 15, Unit Input/Output Screen
The screen shown in Figure 15 to the left gives the status of the
unit
controller digital
inputs and outputs and analog outputs. The unit controller in concerned with the
operation of the entire unit and its I/Os reflect this. Note that operation of condenser
and evaporator water pumps and tower operation constitute most of the data flow.
An illuminated block (gray in the figure) indicated that either an input or output
signal exists.
Pressing the Evaporator or Condenser buttons on Detail View Screen will display
pertinent vessel temperatures and pressures. The screens are very simple, self-
explanatory, and not shown here.
