The results presented on the analog output signal channels (displayed on the
User Interface) are held constant until new values are determined. Since it is
not possible to represent the '<' (less than) symbol on the analog signal chan-
nels, check the following for clues to determine whether the HCDP tempera-
ture is 'equal to' or 'less than' the value indicated by the analog signal:

The analog input/output (and alarm relay) terminations are made on the
Termination board inside the Electronics Enclosure. Signal wires, contained
within conduit (complete with connector and seal) that is approved locally
for the hazardous location, enter the Electronics Enclosure through the Signal
Cable Entry on the top of the enclosure. The terminal assignments are identi-
fied in Figures 2-3, 2-4, and 2-5.

View the LEDs on the User Interface to determine if any alarms have been
triggered. If LED 4 (Hydrocarbon-Dewpoint-Temperature-Not-Found) is On,
the HCDP temperature was not detected and, therefore, is 'less than' the
actual reading.
View the RUN menu for the current HCDP temperature.
View the SCode and XSCode (Stat\History menu) for HCDP-related
alarms.
If necessary, view the HCDPA sub-menu item (ApplicCFG menu) to view
the current HCDP temperature Off-Spec Alarm setpoint.
