Wiring the Remote Start (Binary Input) Connection
The 900 On-Line Analyzer remote start (binary input) connection can be wired in a variety of ways
and is intended to execute a start/stop command to the Analyzer from a remote location, such as a
Process Logic Control System or Center (PLC). Wiring examples are shown in Figure 7 and Figure 8.
Note that binary input must be activated in the Analyzer firmware later. It is important to confirm
the correct signal strength before setting binary input to On, to avoid unexpectedly starting or
stopping analysis. For more information on activating binary input, see “Activating Binary Input” on
page 110.
