Step 3: Selection and Naming of Auxiliary Analog
Inputs used for Level Control
Navigate to page 4 of the Confi guration screen and se-
lect the analog inputs(s) that will be used for sensing the
4-20ma signal from the vessel(s) level probe(s). Also
provide a name for the analog input(s). You’ll need to
reference your wiring diagram to determine which ana-
log inputs need to be enabled.
In the example in Figure B-31, Auxiliary #5 Analog Input
was renamed to “Chiller Level 4,20 Input” and Auxiliary
#6 Analog Input was renamed to “Condenser Level 4,20
Inputs”. Referencing the wiring diagram, please note
that Aux #5 Analog Input corresponds to Channel #21
on the wiring diagram and Aux #6 Analog Input corre-
sponds to Channel #22 on the wiring diagram.
After steps 1, 2 and 3 have been completed, then press
the APPLY button and then press the CLOSE button to
exit the Confi guration screen.
Continue to step 4.
