Analyzer display description

When started, the analyzer display shows the serial number and
firmware information for the analyzer. After startup, the analyzer display
shows the information shown on the controller display when it is in multi-
channel view.

Startup

Start the analyzer

1. Open the upstream isolation valve to let sample flow to the analyzer.
2. Push the analyzer power button to start the analyzer. The analyzer
does a series of self-diagnostic routines.
3. For portable analyzers, set the power switch for the printer to on ( | ).
4. Make sure that the display on the analyzer (S10 and XP-S models)
and controller come on. The channel LED on the controller for the
)
analyzer flashes red while the controller tries to make a
c
10
communication connection with the analyzer.
5. If "Sensor Head not communicating" is shown on the controller or if
the controller or analyzer fails to operate, examine the cable
connections. Contact Technical Support if the communication failure
cannot be corrected.
6. To see if any other alarms occurred, push ALARM.
7. When the self-diagnostic routines are completed, the sample flow
starts and the analyzer does an analysis cycle. Make sure that there
is flow to the analyzer. If there is no flow through the instrument,
make sure that the upstream isolation valve is open.
