User Interface
Using an instrument screwdriver, open the top cover of the sensor to gain access to the user interface
panel. This panel contains a pushbutton, node-address switches, and LED indicators for configuring and
viewing the sensor’s operation and status. A more complete description of each item is described below.

Address
Pushbutton
A single momentary pushbutton, labeled LRN, is used to “teach” the sensor the application presented to it.
Refer to the Self-Teach in this document for complete instructions on using this feature.
Selector Switches
Two selector switches are provided for setting the sensor node address on the network. Possible addresses
range from 063. The node address may also be set over the network using the RS Networx configuration
tool.
LED Indicators
Three LED indicators are provided to indicate a variety of conditions making it easy for installation and
troubleshooting. The function of each is described in the table below. The LEDs also work together as
indicated on page 5 when used in the self-teach mode.

Note: LED indicators are used during the Self-Teach operation of the sensor. Refer to the Self-Teach
section for complete instructions on using this feature.
Mounting the Sensor
Securely mount the sensor on a firm, stable, surface or support using one of the many mounting brackets
available from Rockwell Automation/Allen-Bradley. The sensor is supplied with hardware kit #129--130
which contains a plastic mounting nut, lock washer, 2 M5 x 0.8 x 53 screws and nuts. Excessive vibration or
shifting may cause intermittent operation of the sensor.

Wiring the Sensor
Models of SmartSight are available in one of three different connection types as identified in the following
table. Rockwell Automation/Allen-Bradley recommends the use of the 1485R Series of cordsets and
patchcords on the quick-disconnect models.
ATTE N T I O N : All external wiring should conform to the National
Electric Code and all applicable local codes.

Configuration
After securing the sensor to a stable surface or support and connecting to the network, it will be necessary
to configure some of the parameters using a suitable network configuration tool such as the Rockwell RS
Networx. For remote configuration the DeviceView Handheld Configurator (193--DNCT) is available. Note
that the node address setting can be set locally using the two switches located on the user interface panel.
The address can also be configured over the network.
Self-Teach Operation
SmartSight DeviceNet photoelectric sensors p rovide self-teach operation for learning the application
presented to it. In essence, it automatically adjusts its sensitivity level to help distinguish between the target
and the background. This feature eliminates the need to manually adjust a sensitivity potentiometer as
found on the earlier DeviceNet 9000 photoelectric sensor. The self-teach can be accomplished either locally
or over the network.
Local Self-Teach
1. Open the top cover of the user interface panel and locate the LRN pushbutton.
2. Press the LRN pushbutton for five seconds to enter the Learn mode. The bi-colored LED will alternate
red/green/red to indicate that this mode is active.
3. To learn condition #1 (background or target), press and release the LRN pushbutton quickly. The Yellow
LED will turn ON.
4. To learn condition #2 (opposite of condition #1), press and release the LRN pushbutton quickly. If the
learn was successful, the yellow LED will turn off then on again. If the sensor was unable to learn the
application, then go to number 6.
5. The sensor will automatically exit the Learn mode and is now ready for operation.
6. If the sensor was unable to establish sufficient contrast difference between the condition #1 and #2
(background and target), the Red LED will turn ON indicating a Learn failure. Try the Learn process
again.
7. If, after a second attempt, the sensor is still unable to learn the application, it indicates that there is
insufficient contrast in the application. Retry the Learn operation using RS Networx as it may be possible
to learn the application by manually setting the sensitivity level over the network.
Remote Self-Teach
Using RS Networx, it is possible to enter the Learn mode to teach the sensor. This process is similar to that
described for the local self-teach and is supplemented with extensive help functions.
ATTE N T I O N : In most retroreflective, polarized retroreflective, and
transmitted beam applications, it is not necessary to
make any sensitivity level adjustments.
Due to the detection method, adjustments may be
required for diffuse sense modes.

Diagnostic Operation
The SmartSight DeviceNet photoelectric sensor provides two independent diagnostic outputs to indicate an
unstable sensing condition. These two diagnostic outputs may be configured to operate in one of two
possible modes. The first, static, is designed for web sensing or other applications in which an immediate
diagnostic output is required. The dynamic operating mode is useful in repetitive applications where targets
are constantly moving into and out of the sensors field of view. In this mode, the output bit will only b e
triggered after detection of seven successive “unstable” signals. This prevents “false triggering” caused by
the leading and trailing edges of the target.
A third diagnostic output bit is also provided. This output will be activated when either the Margin 1 or
Margin 2 diagnostic, or the Motion Detect preset values is reached.
