Figure 10: Location of Digital Output Terminals on IO Board
The user may connect to any or all of the available digital signal terminals as per their specific
requirements. For a detailed drawing showing the digital signals connections on the IO
board, refer to the
DC Signals and Wiring Diagram
drawing (Figure 86) in Section 9 of this
manual.
Installation of the conduit, wiring, and disconnect devices must comply with all
applicable, national, local, and company electrical codes. All connections must
be ‘sealed’.
2.4.6 Connection of the Instrument Air
The installation of the analyzer system requires the connection of
instrument air
to the air
filter. The instrument air must be at a pressure of 80-100 psig (5.5-6.9 barg), and must be
clean, dry, and oil-free as per ANSI/ISA Standard 57.3-1975 R (1981). The instrument air
supplied to the analyzer must be capable of a sustained flow rate of 22 SCFM (37m
3
/hour)
at 80 to 100 psig.
Prior to connecting the instrument air line to the analyzer, all air lines should be blown down
to remove any possible debris such as dirt, scale, water, oil, etc., that could contaminate the
analyzer system.. The system
air pressure regulator
, complete with a pressure gauge, is
mounted on the left side of the analyzer system as shown in Figure 11.
