Rockwell Automation Allen-Bradley VisiSight 42JT Series Installation Instructions

42JT VisiSight™ Photoelectric Clear Object Sensors

Default Settings:

Output Mode: Dark Operate (Output ON when the light
between sensor and reflector is blocked)
Output Type: Auto PNP or NPN (The sensor monitors the load
connection continuously and automatically configures the
output to PNP or NPN)

Sensor User Interface

Yellow LED

LED Status

The table below provides LED status in the RUN mode i.e., during
operation, the sensor is always in RUN mode, except when being
taught.

Mounting the Sensor

Securely mount the sensor on a firm, stable surface or support.
An application which is subject to excessive vibration or shifting
may cause intermittent operation. For installation convenience,
Rockwell Automation offers a wide range of mounting brackets
(see the Accessories section for more details).

Alignment Indication

For short range applications the visible light beam of the sensor
suffices as alignment aid.
The alignment feature may be used for longer range applications.
Alignment of the sensor is indicated via change in intensity of the
green LED in the Alignment Mode, as follows:
1. Press and release the pushbutton twice within three seconds.
After three seconds, the green LED turns OFF for 0.5 second
indicating the sensor is in the alignment mode.
2. Align the sensor to the reflector. The intensity of green LED
increases with better alignment. Secure it in a position that
