Installation
1. Install the sensor – see Installation instructions page 2.
2. Connect Pin 2 of the PWR IO connector (8-pin) to 24 V DC; Pin 7
to ground, and the in- and outputs depending on your applica-
tion. Connect the cable shield to ground!
3. Connect the TO PC connector to an available network terminal
on the PC after connecting the sensor to power. More information
on mounting and electrical connections can be found in Section 2
of the Operating Manual.
Startup
Note: To carry out Steps 1 and 2 you must have administrator rights
on your PC. Please contact your IT representative to check whether
you do have these rights.
1. Install the BVS ConVis software
Install the BVS ConVis software on your PC from the DVD. After
inserting the DVD in the DVD drive the DVD should start automati-
cally. Select "BVS ConVis Installation". Depending on your Win-
dows 7 security settings a dialog: „View Downloads" can come up.
Select „Run" behind in the row with „setup.exe" and select „Run"
again when the dialog asks if you want to install, as the distributor of
the program is unknown.
If the DVD does not start automatically, you can find the file setup.
exe in the directory User_Interface_EN on your DVD drive. Start
installation by double-clicking.
2. Establish network communication sensor ó PC
When first starting up a BVS-E sensor the PC network settings must
be configured. To do this proceed as follows:
► Click on the Windows "Start" button
► Select "Control Panel" à "Network Connections"
► In the network connections menu select: "View" à "Details".
Data!
Your network connections are displayed as follows:
► Note the display and briefly disconnect the network cable to the
BVS-E from the network socket. The following text is displayed in
the STATUS column for the corresponding network connection:
Network cable removed
► Double-click on the icon for this network connection - the "Prop-
erties"- "Local Area Connection Status" window is opened.
Reconnect the network cable.
► Click on "Properties" button at the bottom of "Local Area Con-
nection Status" window. Then drag the scroll bar down and select
"Internet Protocol (TCP/IP)". Click on "Properties".
► Click on the tab: "Alternate IP Address"
► Enter the following IP address and subnet mask: IP address:
172.27.101.1 Subnet mask: 255.255.0.0
► Click on OK to close the "TCP/IP Properties" window.
► Click on OK in the "LAN Properties" window.
► Wait until the STATUS of the network connection changes to:
"Connected".
between BVS ConVis and the sensor
Prerequisite: Steps 1. and 2. were carried out, sensor power is on.
► Start the BVS ConVis software. Click on Options and select
"English" as the language.
► When starting the BVS ConVis software the "Connection Selec-
tion Mode" window appears, click on the "Find sensors" option
and then click "Ok". After a short time the software will display the
found sensors in the Control Panel (upper right).
► Click on the "Connect" button if the displayed sensor information
is highlighted in GREEN. The software automatically checks the
firmware version on the sensor and shows you the result in a
dialog box.
► Click on OK – live images will be immediately analyzed.
If the displayed sensor information is highlighted in RED or you
receive the message: "No sensors found in network", then please
read Section "9.3.4 Fault remediation" in the Operating Manual.
More information about Step 3: Manual Section 4.3 and 9.3.
4. Focus sensor and make basic settings
Prerequisite: Steps 1. – 3.completed. The BVS sensor's internal ring
light "flashes" from time to time, and new images are continually
displayed on the screen. In the Control Panel (upper right) the basic
settings are displayed.
► Now click on the "Automatic" button and wait a short time.
► Set the image sharpness by turning the focus ring on the sensor.
Turning the ring clockwise brings farther objects into focus – turn-
ing it counter-clockwise brings closer objects into focus.
► If your brightness value is over 6: Change "Internal light" to
POWER.
► After focusing or cycling the power click on "Automatic" again.
► Now you can make the fine adjustments to sensor's alignment
and focus. To prevent reflections from shiny parts, change the
angle of the sensor of 5 to 15 degrees from the vertical axis of the
object.(see Mounting - page 2 for details).
► Use "Trigger mode" to determine which trigger signals the sensor
responds to. Possible are:
– Continuous: The BVS captures and processes images without
interruption.
– External (rising or falling edge): The BVS captures and processes
an image as soon as the edge of an external signal (from 0-24 V
to 24 V or 24 V to 0 V) is registered on the trigger input.
► Manually change the brightness and contrast so that the features
you are inspecting show good contrast, then click on "Stop live".
► Use "Set reference image" to use the image displayed on the
screen as the reference image.
For additional information on Section 4 see:
– In the BVS ConVis "Help" window (bottom left). Help is divided into
questions. To read the answer to a question, simply click on the
question.
– In the Operating Manual Section 5 – A description of the "Basic
Settings" can be found in Section 5.2.5, information about trig-
gers in Section 5.2.6.
5. Configure inspection and set outputs
Prerequisite: Steps 1. – 4. complete; and a reference image set. A
"tool" inspects a defined Region Of Interest (feature) in the image for
certain criteria.
More information on Steps ► Click "Select tools" to select from the following tools:
1. and 2. can be found in

in Region Of Interest (ROI).
3. Open a connection Contrast Calculates differences between
lightest to darkest pixels in ROI.
Tool Description
Position Locates position of edge transition in
pixels in ROI.
Contour Searches for taught outline or
contour in ROI.
Count Counts number of edge transitions
edges in ROI.
Pattern Searches in X and Y directions for
taught pattern within search area.
Width Measures distance between two
edge transitions in pixels like calipers.
360° Detects a pattern in the search area and within
Pattern defined angles, BVS Advanced only
detect
After selecting a tool the pointer takes the shape of each tool's icon.
Click the pointer on the location in the image where you want to
insert the tool.
Now the tool image area is displayed as a GREEN (= OK) or RED (=
NOK) frame.
► Use the mouse to change the size, position and, if needed,
rotation angle of the Region Of Interest you are inspecting (see
Manual Section 5.3.1).
► Now set the tool parameters to match your inspection task. ( see
"HELP" or Manual Section 7.2)
► To add additional tools, click on "Select tool", or you can copy the
current tool by clicking on the tool to copy (if you have multiple
tools verify the correct tool to copy by reviewing the parameters in
the "Control Panel") and press Ctrl + C and then to paste it use
Ctrl + V.
► Then click on "Set outputs" to associate the final result (OK or
NOK) with an output. ( see "HELP" within the ConVis software or
the Operation Manual Section 5.3.5 and 7.3).
Note: Information on using Locator tools can be found in "HELP", or
in the Manual Section 7.1.
6. Test and apply
Prerequisites: Steps 1) – 5). After clicking on "Test" and then "Start"
the camera is in a live state and begins the inspection and analyzing
acquired images. The connected sensor only records images and
sends them to the PC, which then processes them. All the outputs
on the sensor are deactivated during "Test".
Click on "START" to start a test, and on "STOP" to end the test.
In the test the "Image display" shows the current image and the tool
results; the "Operating field" displays the simulated "Output status".
You can use the "Inspection Explorer" to monitor tool parameters.
► Click back to Step 2 to adjust the tool parameters if necessary,
i.e. if the test inspection does not function as desired.
For additional information on testing see Section 5.4.2 in the Manual.
► Click on "Run" to save the inspection on the sensor and run it. The PC
can be used to monitor the cycle. All outputs are active in the "Run".
► Click on "START" to start the cycle, and "STOP" to end it.
If the "Show images" option is enabled, the images are sent from the
sensor to the PC - if Statistics is enabled, the PC only calculates
statistics, NO images are shown.
► If the inspection is not yet stored or has been changed, it must
first be saved on the sensor.
► Does the inspection run like it was supposed to? - Then you can
disconnect the sensor from the ConVis software: Click on
"Offline". The sensor now runs autonomously. You can unplug the
cable from the TO PC plug.
Information about "Run".: Manual Section 5.4.3.
