b. Analog Output Setup
In the System SIO Module menu (Figure
3-25), select Analog output setup…
Select analog output number
Choose the desired analog output (1-8) to
set the parameters. The number of out-
puts depends on the analyzer configura-
tion as 2, 4, 6, or 8.
Choose the analyzer module
Select the “Analyzer Modules” submenu
by selecting the “Choose signal source
module…” line and pressing the
↵ key.
Select the tag of the desired reference
channel with the
↑ or ↓ keys and then
press the ↵ or → key. The display will re-
turn to the previous menu automatically
and the selected reference channel will be
displayed in the “Source module:” line.
Choose signal
Select the “Signals” submenu by select-
ing the “Choose signal…” line and press-
ing the
↵ key.
Note: the parameters “Operation status”
and “Validity” are not functional on the
TO2. The list of signals will depend on the
module chosen.
Pr
Press the F5 key to go to a further menu
to choose the Primary Variable signal for
the analog output. The Primary Variable is
the actual oxygen concentration.
The signal chosen here will be applied to
the analog output (1-8) chosen above.
