Troubleshooting
7.1.1
Web Interface Communication
If an error page is displayed in the web browser, please check the following:
-
Check if the controller is connected correctly, see Chap.
-
Check the IP configuration for PC and controller, and check if
Sensorfinder.exe
(ap-
plication on the CD-ROM) can locate the controller, see Chap.
.
If controller and PC are connected directly, IP address detection may take up to 2 min-
utes.
-
Check the proxy settings. If the controller uses a separate network adapter to connect
to the PC, you need to disable the use of a proxy server for this connection. Contact
your network specialist or administrator!
7.1.2
Distance Measurements
If the
Range
LED does not come on, even though a target object is positioned
within range, check the following.
-
The cable connections of the optical fibers and the sensor cable are plugged fully into
the controller's cable socket.
-
The sensor is sending out a light beam, and the light is visible on the target object.
-
The target object is positioned within the measuring range, see Chap.
-
The sensor is aligned vertically to the target object. Local measuring point increases
(ie. angle between the optical axis and the target object's vertical straight) do not ex-
ceed the maximum sensor tilt angle.
-
The lowest measuring rate is selected, and Distance is set as measurement type.
-
The dark signal was captured correctly.
-
Check the video signal: is only one peak above the recognition threshold?
7.1.3
Thickness Measurements
If zero (0) comes up as a result for thickness measurements (error), please check
the following:
-
The thickness of the target object must correspond to the sensor's measuring range
limits, see Chap.
.
-
The target object must be sufficiently transparent.
-
The surfaces should not be anti-glare, as the coating allows only for minimum reflec-
tion.
-
Optical axis and target object surface are perpendicular.
-
The lowest measuring rate is selected.
-
Both surfaces of the target object must be positioned within the measuring range, see
-
Check the video signal: are two peaks above the recognition threshold?
7.2
Changing the Sensor Cable for IFS2405 and IFS2406 Sensors
Disconnect the protective sleeve from the sen-
sor.
Remove the damaged sensor cable. Loosen the
swivel nut of the connector. Carefully peel off the
adhesive protection and then pull out the connec-
tor
Guide the new sensor cable through the protective
sleeve.
Remove the protective cap on the sensor cable and
keep it.
