4-64 | Model 933S UV Analyzer
Scode History
These readings are history buffers for the Host Controller (HC Scode)
and Microcontroller (MC Scode) boards, for the last five measuring
cycles. Each history buffer displays a status code (if any alarms have
been set), which is a sum of the primary error codes, where ‘1’ is the
most recent status code and ‘5’ is the oldest. To resolve a non-primary
status code into its primary error codes, click on the history buffer
fault or warning status code. The alarms that make up the status code
will be displayed under the HC Scode and MC Scode alarm lists.
Analog Outputs
Displays the assigned analog output name (up to four) and its real
time status. If no output is assigned to a channel, “none” will be
displayed next to the channel number (for example, “4 – none”). The
outputs will be different for each analyzer/application.
I - Output Displays the analog current output.
V - Output Displays the analog voltage output.
During normal conditions (for Analog Outputs and Live Conc), the
text is Green; when there is a Warning or Fault alarm present, the
text is Red. If an alarm is active, see “Troubleshooting and Diagnos-
tics” in Chapter 6 for details about the alarm and corrective action to
take to reset the alarm.
Live Conc
Located to the right of the Scode History buffers, the live concentra-
tion values for each component are displayed (updated at one-second
intervals).
Operational Message
This message box displays the current analyzer status. Messages that
can be displayed here include:
Flow Control not in Auto The analyzer is operating in a Flow Control
mode other than ‘0’ (auto), which is the nor-
mal operating mode.
CAL in progress An analyzer calibration is being performed;
the calibration time remaining is displayed on
the Analyzer Data tab (Time to end of cal).
Stabilizing concentration readings
The analyzer is stabilizing (prior to opera-
tion), following power-up or a reset.
