This isolated relay output lets you set various switching functions set,
which depend on the analytical sequence.
Select in the menu =>basic program => Relay AUX.
You have the following configuration options:
Active "Before retry": In this case the relay AUX e.g. is used to
control an external purge valve. If a limit value has been exceeded,
but the number set for the limit value occurrences was >1, the re-
lay switches before each measurement is repeated. The purge
procedure is performed for the set time. This can help prevent
measurement errors due to insufficient purging.
Active "Before analysis": e.g. for external purging switches the
relay for the set time before each analysis.
Active "During analysis"
Active "Before, during analysis"
Active "After analysis"
In addition, it is also possible to specify a time interval for which the
relay remains active.
Alarm (Fault signal output)
The device includes a relay "Alarm” output to notify faults.
A error is signaled via the LED alarm and the corresponding error
message is shown on the display. You can configure whether and
how this indicator should be shown.

Select the signaling for each type of error.
You can set whether the error alerts
are not provided at all (by selecting "-" in the menu).
