WCC3.EXE SCREEN DESCRIPTIONS
WCC III Technical Guide 3-64
MODE
An “alt” message may be displayed in this column to inform you
that analog output is in its alternate mode. When the status of the
binary input which has been entered on the analog output screen to
select the alternate mode is “ON,” the alternate control limits are
used, and the “alt” message is shown here.
CURRENT INPUT
The value of the analog input associated with the Analog Output
Screen is automatically displayed here. For example, if you are
controlling a chilled water valve based on supply air temperature,
the supply air temperature will be shown here.
INPUT RANGE OUTPUT RANGE
You specify an output voltage for a given analog input signal on
the Analog Output Screen. The values which are input on the
analog output screen are shown here. For example, if you input the
following ranges on the Analog Output Screen:
Output = 0.0 volts when input is 50.0 °F
Output = 15.0 volts when input is 60.0 °F
The Summary Screen would look like this:
INPUT RANGE OUTPUT RANGE
50.0 - 60.0 0.0 - 15.0 V
