6.4.1.6 “SLWarning” switching mode
6.4.1.6.1 Description
The “SLWarning” switching mode is only accessible if the “Advanced” user level is
activated.
Output of a switching signal occurs if a set level threshold or signal level switching point
is undershot (High Active) or exceeded (Low Active).
Utilization of the signal level warning can be useful for outputting a warning message
if measurement conditions are marginal (for example, outputting a warning message
for objects that must be measured). When measuring a reference object using known,
uniform optical properties, the signal level warning can also be used to notify a user of
required cleaning of the optical boundary layers

If the “SLWarning” switching mode is activated, the level threshold to be defined can
either be taught in using a reference object or manually configured. These options are
described below.
