MINI-BEAM® Expert™ is a complete family of sensors, all housed in the

popular, robust and compact rectangular housing. Their large push button

and easy-to-see indicators provide easy configuration, alignment, and

monitoring during use.

Status Indicators

Normal sensor operation is called RUN mode. Sensor configuration (setting the sensitivity threshold and selecting output

ON and OFF conditions) is performed in TEACH mode. The two LED indicators (bi-color green/red and amber) have distinct

roles in the two operation modes. If contrast is marginal, the bi-color indicator will flash green to indicate instability. If this

occurs, reconfigure or realign the sensor, or clean the sensor or fiber lenses.

The Signal Strength indicator is Banner’s exclusive AID™ (Alignment Indicating Device). Its pulse rate increases as the

received light signal strength increases (during programming). This feature simplifies accurate alignment during TEACH

mode, and gives a relative indication of sensing contrast between the light and dark conditions.

3 This is the Stability indicator, which signals when maintenance, realignment, or reconfiguration is needed during RUN mode.

4 The faster the pulse rate, the stronger the light signal.
