Chapter 4: Installation
Installing the 4-20 mA Connection
The data from the Analyzer may be recorded using the 4-20 mA outputs located on TB1. Each analog output is
assigned to a particular sample stream. 4-20 mA output #1 provides an analog signal proportional to the
concentration measured in sample stream #1. Output #2 provides a signal proportional to the concentration
measured in sample stream #2, and so forth. The analog output is calibrated at the factory prior to shipping. An
example wiring connection for one of the 4-20 mA outputs is shown in

Installing the Remote Start (Binary Input) Connection
The Analyzer remote start (binary input) connection, located on TB2, 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 (PLC) System or Center. Wiring examples are shown in
Binary Input using Analyzer's Internal Supply
used to power the binary input.
No menu configuration is necessary. For more information on diagnostics testing of the binary input, see
"Binary Input" on page
240.
Remote start/stop using binary input works in tandem with the display Start and Stop Analysis button.
Changing the state of the Remote Input will change the Analysis Run state if not already in that mode. The
Display Start/Stop Analysis button remains functional while the remote start/stop is in use. This allows for
manual override of the analysis mode.
