The Valve Position indexes (ii=12 and ii=0C) each have two states (00/01) that when combined
provide four (4) possible states of the C1/C2/C3/C4 internal valves. This “Logical Rotary
Switch” with four (4) positions is summarized in the following chart:
C1 Energized
C2 Not
(0C=01)
C2 Energized
C1 Not
(0C=00)
C3 Energized
C4 Not
(12=01)
PURGE
position
LEAK/CHECK
position
C4 Energized
C3 Not
(12=00)
CAL/RE-ZERO
position
RUN
position
Example:
● Send TCP/IP commands to Model 9116 module (via its connected socket)
setting the calibration valve to the CAL (or Re-Zero) position:
“w1200" (Set RUN/CAL valve position)
“w0C01” (Set CAL position)
Responses (both commands):
“A”
“A”
Note
If the programmer “knows” that the module is already in the RUN/CAL
valve mode, the first command above is optional. For more information,
see Figures 4.1 through 4.4 in Chapter 4.
