14.1 Adaptive trigger
The adaptive trigger is a plug-and-play solution.
With the adaptive trigger, manual sensor
configuration is not required, since the trigger
will automatically configure the output signal to
react to a new medium. The adaptive trigger is
very useful for applications with sticky media or
for applications where the medium is changed
frequently.
Normally, it is not necessary to configure the
adaptive trigger, but if the advanced setup is
enabled, it is possible to define low and high
set points for the adaptive trigger window and a
damping. The steady detection function ensures
that the input signal is steady for 1 second before
the switch output reacts. If the steady detection
function is inactive, the switch output will react
immediately to each input change.
If required, teaching the Adaptive Trigger can be in
empty tank state (zeroing), for example, to supress
any interfering influence that may be present.
Doing so is with the aid of qTeach (see page 15) or
by restore default.
In the event of restore default, the zeroing
operation is only performed after having power off
and on again.
14.2 Analog 4 ... 20 mA
The analog signal (4 ... 20 mA) represents the
complete range of the sensor from 0 ... 100 %.
The analog signal can be used to evaluate different
media in the application.
It is possible to zoom on the sensor range, so that
the resolution of the signal is higher within the
zoomed area. Additionally, the analog signal can
be reversed.

Adaptive trigger – hygienic/industrial
To ensure a fully functional adaptive trigger, the
following conditions have to be fulfilled:
The sensor has to be in air during startup.
The input signal has to be steady.
The difference between the value for untriggered
and the value for triggered must be more than 3
%.
If a new medium with a DC value lower than
the previously configured DC value has to be
detected, the sensor tip should be cleaned before
the new medium is filled in the tank or pipe.
