Selecting a subfunction and changing the setting
1.
Rock to left or right to select the desired subfunction.
2.
Press rocker push button in middle position. The currently set value is displayed statically.
3.
Rock to right or left to display the selectable adjustment values - these flash slowly.
4.
Accept the new value by pressing the rocker push button in the middle position.
Fast flashing indicates that the new value is accepted.
5.
Automatic return to the heading for the subfunction.
6.
Press again to statically display the previously selected value.

The response time is the max. time required by the switching output to
switch to the active state following a signal change at the input.
From this, the switching frequency can be calculated as follows:
Notice: A change to the response time is equivalent to a change to the
signal range.

The gain stage can be set either by manually presetting a value between

or automatically by selecting
Auto GAIn
. The left, red display
shows the current signal value.
The gain stage should be selected so that the signal value is approximately
in the middle of the display area.
If

is selected, the device automatically determines the optimum
gain setting

Presetting a suitable teach process.
To trigger the teach event, see
Teaching operating mode
.
1-point teach, static
: during teaching, the current signal value is accepted
as the new switching threshold. Actuate the rocker push button to make fine
adjustments to the threshold.
2-point teach, static
: the switching threshold is calculated at approxima-
tely midway between two signal values, e.g., teach to two different objects
or teach to the same object at two different distances from the probe. Exa-
mple: signal value 1 = 100digits, signal value 2 = 400digits
Switching threshold = 280 digits. Actuate the rocker push button to
+
or
-
to make fine adjustments to the threshold.
Dynamic teach
: suitable for processes that cannot be stopped for teaching.
When the teach event is started, the sensor begins to scan the signal values.
On the left, red display, the signal values are constantly displayed. At the end
of the teach event, the switching threshold is calculated at approximately
midway between the smallest and largest signal value.

The function is only available during dynamic teaching. If the function is
switched on, the switching threshold is automatically and continuously
optimized by the sensor in such a way that maximum functional reliability is
ensured.
This can be used to compensate for, e.g., soiling or process changes.
