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 063. 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.
ATTENTION: All external wiring should conform to the National
Electric Code and all applicable local codes.
