4 Functions and features
The object inspection sensor monitors an object for completeness, shape de-
viations or colour changes. The unit uses incident light or back light to detect a
grey-scale pattern of the object. On the basis of the determined brightness values
the sensor differentiates between the object to be monitored and the background.
Then the unit compares the image found with one or several models in a reference
image. Depending on the degree of conformity the output can indicate if a model
was found or which one was found.

5.3 Installation location
►Mount the sensor in front of or above the area to be monitored.The detectable
field of view size depends on the operating distance → Chapter 11.1 Technical
Data.
►Back light or scattered light situations and continuously changing light condi-
tions are to be avoided.
►Do not position room lights directly facing the camera lens.
►Position the optional external illumination (e.g. O2D905) opposite the camera
lens.
►To avoid adverse effects on the image detection, avoid installation in dirty areas
of the machine.
►The connected cables must be provided with a strain relief.

6 Electrical connection
NOTE
The unit must be connected by a qualified electrician.
►Disconnect power before connecting the unit.
NOTE
The voltage on pins 2, 4, 5, 6, 7 and 8 must not exceed the supply voltage on
pin 1 (U+).
►Use the same power supply and protective equipment for
●the device (e.g. O2Dxxx),
●the signal generator at the inputs (e.g. trigger switch, plc),
●the signal pick-up at the outputs (e.g. plc).
As an alternative, a diode at the switching outputs can prevent feedback
(see fig. below).

Output signal "READY" provides the status of the sensor:
"1" after the evaluation has been carried out. "0" as long as the evaluation is being carried out, a
different application is being selected or in case of an internal error (trigger signals are ignored).

Output signal "OUT" provides the result of the evaluation:
"0" no matching model "1" matching model

►For PNP units (e.g. O2V100) use trigger sensors, illumination units and control-
lers with PNP inputs and outputs.
►For NPN units (e.g. O2V101) use trigger sensors, illumination units and control-
lers with NPN inputs and outputs.
6.3 External illumination
►Connect external illumination to the trigger output of the device.
Example Art. no.
Backlight, 100 x 100 mm, infrared light 880 nm O2D905
For information about the example above see:

The evaluation time tAdepends on
●the size of the field of view selected
●the model size
●the selected inspection characteristics
●the number of models
Typical evaluation times are between 100 and 500 ms.
The pulse length tBcan be set between 100 ms and 2000 ms via the PC user
program. For more detailed information about the configuration of the switching
outputs we refer you to the programming manual of the sensor.

6.5.2 Static selection of the application
Up to 32 different inspection tasks can be stored in the sensor. With the corre-
sponding unit configuration the first four applications can be selected via the two
switching inputs.

For the selection of the applications the monitoring time tRand the trigger disable
time tPhave to be taken into consideration.
Monitoring time tR: After a change in edges the external selection of the application
does not start before the state of both switching inputs remains stable for 20 ms.
Trigger disable time tP: The trigger input is disabled during the selection of the ap-
plication. The disable time depends on:
●the number of applications on the sensor
●the number of models in the application to be activated
6.5.3 Pulse-controlled selection of the application
As an alternative to the static selection the selection of the application can also be
pulse-controlled.
12345
1: gate signal, switching input 1 = 0 → 1 → 0 (tG= signal active)
2: pulse signal, switching input 2 or trigger input = 0 → 5 pulses → 0
3: READY output
While there is an active signal on switching input 1 (gate signal), the sensor counts
incoming pulses and activates the respective application.
Number of pulses = ID number of the application
Either the 2nd switching input or the trigger input of the sensor can be used as
pulse input.
For more detailed information about the configuration of the selection of the ap-
plication we refer you to the programming manual of the sensor.

8 Set-up
Set-up is carried out via a menu-driven PC operating program. The device stores
up to 32 applications.
8.1 Parameter setting on the unit
Set the parameter values via pushbuttons and display on the device.
The sensor is programmed using the two buttons [Mode/Enter] and [Set].
First activate a parameter with the [Mode/Enter] button, select the required value
with the [Set] button and confirm it pressing again the [Mode/Enter] button.

 
The unit changes to the parameter setting mode when you
►press [MODE/ENTER] for more than 1 s.
> The first menu item is displayed.
►Press [MODE/ENTER] several times until the required param-
eter is displayed.

 
►Press [SET].
►The menu item is activated and the current setting is dis-
played.
►Keep [SET] pressed.
> The display flashes, after 5 s with SET button pressed the
display stops flashing.
►Press [SET] and change setting.
►Press [Mode/Enter].
> The change is acknowledged and the previous menu item is
shown again.
If no button is pressed for longer than 15 s, you will get to the next
higher menu item or the evaluation mode.
The device does not operate during use of the pushbuttons.
8.2 Verify and set the IP address on the unit
►Select the parameter "IP" (IP address) with [MODE/ENTER] and [SET].
> The IP address is processed automatically and shown in 4 groups (A, b, C, d).
►Verify the IP address and set with [SET], if necessary.
Changes only become effective after a restart of the unit (power off, power
on).

8.3 Adjustable parameters
Memory location
Select an application. The device can save up to 32 applications. By pressing the SET button
the memory location number is incremented in the display. The current state of the memory
location is visualised in the first digit of the display:
F = memory location available
I = memory location used by an inactive application
A= memory location used by an active application
E = memory location (selected by external selection of the application)
Network operation
Here you set the parameters for network operation.
Network settings via DHCP
If the sensor is to get its network settings via DHCP, select the setting "on" in this menu item.
With the setting "off" the fixed network settings (see next menu items) are used.In the DHCP
mode the sensor must be operated in a network with DHCP server. Otherwise it is not acces-
sible via the operating program E2V100.
Set IP address
Here the IP address of the sensor is set. This setting is used when the sensor does not work
in the DHCP mode.The input is made in the "dotted decimal notation", e.g. 192.168.0.3.
Using the SET button you can select the four groups of the address. The respective group is
visualised by a letter in the first digit of the display.
Set subnet mask
Here the subnet mask of the sensor is set. This setting is used when the sensor does not
work in the DHCP mode.The subnet mask must match the IP address. It is input in the same
way as the IP address.
Set gateway address
Here the gateway address used by the sensor is set. This setting is used when the sensor
does not work in the DHCP mode. It is input in the same way as the IP address.
Access extended functions
Here the extended functions of the sensor are accessed.
Rotate / switch off display
Here you set whether a text is displayed normally (d) or rotated by 180° (rd). You also set
whether the display is to be switched off (oFF) in the evaluation mode.
Reset sensor
Here you reset the sensor to the factory setting.
Firmware version
In this menu item you can enquire about the firmware version of the sensor.
Reboot sensor
Here you reboot the sensor without having to disconnect the power supply.
