Parameter
Function
Use
Dark circle on bright background
(hole in steel)
Sets the polarity of the posi‐
tioning mark.
Set whether a light circle on
a dark background or a dark
circle on a light background is
present.
Holes appear dark on
light backgrounds. Reflectors
appear light on dark back‐
grounds.
Diameter scaling min - max
Defines the allowed variance
in the circle size.
Example: 0.85 … 1.15 corre‐
sponds to 85% to 115% of the
expected circle diameter.
Circle diameter defines what
the device considers to be a
valid positioning mark. If the
area is set too high or too
low, circles can be overlooked
or too many potential circles
could be detected as possi‐
ble positioning marks. Use this
parameter to compensate for
the scaling effect based on var‐
iations in the distance between
the device and the rack.
Ellipse minor axis [mm]
Enter length of the minor axis
(blue arrow) for elliptical hole
shapes.
Use this parameter for ellipse-
shaped positioning marks.
Specifying the minor axis
length enables the positioning
mark to be detected more relia‐
bly.
Ethernet mode
Set communication protocol
for Ethernet interface.
Adjust setting to the communi‐
cation protocol of the controller
used.
Gain factor
Manually adjust the image
brightness.
Manually adjust the image
brightness so that the position‐
ing mark is as visible as possi‐
ble.
Reboot device
Reboot device.
Restart the device in the event
of errors.
View stored image
Display the currently saved
image in SOPASair.
The saved image is displayed
and current continuous meas‐
urement is switched off.
Reprocess stored image
Reprocess and evaluate the
image currently saved in the
device.
The saved image is processed
again with the adapted settings
of the algorithm.
Bright circle on dark background
(reflector)
Sets the polarity of the posi‐
tioning mark.
Set whether a light circle on
a dark background or a dark
circle on a light background is
present.
Holes appear dark on
light backgrounds. Reflectors
appear light on dark back‐
grounds.
Invert X/Y axis
Exchange output values for X-
axis and Y-axis.
Possible application: The
device has been installed in
the system upside down.
