ACF5000 FTIR ANALYZER SYSTEM
Explanation
It is to be set whether an adjustment or a validation should take place. In the
working mode parameter, after the validation has been selected, it must be
set whether the result of the validation is to be entered in the logbook and
whether the Maintenance request status is to be set in the event of failure of
validation or an adjustment of the measured components should be carried
out.
The zero and span test gas concentrations to be used as set points for au-
tomatic adjustment need to be set for the selected sample component and
measuring range. In addition, for every measured component the limit values
must be set or the start and end points, and, in the event of the component
falling below or exceeding these, the validation is rated as a failure.
The measured components to be adjusted with the zero point and end point
adjustment must be selected.
Automatic adjustment is always canceled in the event of a system bus error
and when setting the block input. You can configure if the automatic ad-
justment is to be terminated when one of the three states occurs during the
procedure: "System failure", "Analyzer failure" or "Analyzer maintenance re-
quest". You can configure if the analyzer system should repeat automatic
calibration after the cause of termination has been eliminated. Set the num-
ber of repetitions and the time between repetitions.

To be set (recommended settings in brackets) how long after feeding in the
test gas until the start of the adjustment (> 180 seconds), for joint zero point
and end point adjustment after feeding in the end point test gas until the
start of the end point adjustment (> 240 seconds) and after the fresh feed-
ing in of the measuring gas until the start of the measuring procedure (240
seconds) the gas paths are to be purged so that no gas residues falsify the
adjustment or measurement result.
The task time of the test gases after the purging time is to be set. Recom-
mended setting: 0 seconds.
To be set whether the test gases for automatic adjustment are connected at
the separate test gas inlets or at the sampling probe.
If the test gases are connected at the separate test gas inlets, the built-in
pressure switch can be activated during automatic adjustment to monitor
the flow of the test gases. If the flow is insufficient, adjustment is stopped.
The pressure switch can be activated for zero point gas, end point gas and
zero point and end point gas.
Whether zero adjustment will always or never be carried out individually, i.e.
without subsequent end point adjustment, should be set.
Whether end point adjustment will always or never be carried out individually,
i.e. without prior zero point adjustment, should be set.
Whether zero and end point adjustment will always or never be carried out
jointly, or at every nth automatic adjustment, should be set.
The adjustment method for automatic adjustment needs to be set for the
selected sample component. The measuring ranges for the start and end
point adjustment for the common and substitute gas adjustment are se-
lected in the Manual Adj. → Adjustment Method parameter.
Automatic adjustment takes about 18 minutes.
