18.3 Switching Outputs
The menu
Switching Outputs
allows for the parameterization of the three switching outputs, identified
as Q1, Q2 and Q3.
You can set independent parameters for switching outputs Q1, Q2 and Q3. Example shows the setting
for Q1. Similarly, parameters for outputs Q2 and Q3 can be set. Distance values are given in mm. If in
basic configuration Q3 has been assigned an alarm behavior, then only the selection “normally closed”
or “normally open” will be possible.
Active range (
measuring window)
In the boxes
active range from
und
to
you can enter the distance range, going from the frontal edge
of the sensor housing up to the object. This is the range in which output will be active.
Teach ON
With the button
Teach ON
you can define an object lying in the sensor detection range as switch-on
reference for the switching output. The value will be displayed in the box under the button.
Alternatively you can enter a figure in mm.
Teach OFF
With the button
Teach OFF
you can define an object lying in the sensor detection range as switch-off
reference for the switching output. The value will be displayed in the box under the button.
Alternatively you can enter a figure in mm.
For example: By entering a value of 250 mm in
Teach ON
and 1000 mm in
Teach OFF
, you cause Q1
to switch as soon as LMA/B detects an object at least at 250 mm distance from the front edge of its
housing. As soon as the object distance gets higher than 1000 mm, the output reverts to its initial
condition.
Switching hysteresis
Hysteresis ensures stable switching output operation. Switching hysteresis defines the smallest
distance change at the beginning or at the end of the active range, necessary to generate output
switching. You can set a millimeter value in the box
Switching hysteresis mm
. Value can be as low
as 1 mm.
