Setting
Description
switching point
•
The distance to the reference background for the “Object between
sensor and background”
(ObSB mode
) switching mode can be set man‐
ually in millimeters via the switching point.
•
The teach function can be used to teach in the target and reference
background for the “Object between sensor and background” (
ObSB
mode
) switching mode.
Tolerance
With the “Tolerance” setting, the tolerance around the background can
be manually set to
±10 mm
,
±25 mm
or
±50 mm
.
Example ObSB mode parameterization for Q1:
1.
Connect to the device and switch to the
Outputs settings
page in SOPAS ET.
2.
Set the Q1 switching function to
ObSB mode
.
3.
Enter the distance to switching point 1 in the input window (optional: position the
object at switching point 1 and perform a
Teach
).
4.
Select a suitable Q1 tolerance according to the application properties (
± 25 mm
5.
Transfer parameters the device using the “Write all parameters” button.
6.
Check whether the function works appropriately for the configured parameters!
7.3.3.4
Signal level warning (VMA)
The signal level warning (VMA) can be configured via the switching function for Q1 and
Q2.
The necessary settings can either be taught-in or set manually. These are described in
the following.
For a detailed functional description,
see "Non-safety-related functions", page 20
.
A switching signal is output when the level falls below a configurable threshold or the
signal level switching point. The switching signal is then High (“Active high”) or LOW
(“Active low”).
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 interfaces of the device.
