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.
LED RUN Mode TEACH Mode
Solid green Power is on
Flashing green Sensed light level is approaching sensing
threshold3
Solid red Sensor “sees” its own modulated light source; pulse rate is proportional to the
received light signal strength4
Amber on Outputs conducting Ready to TEACH output ON condition
Amber off Outputs not conducting Ready to TEACH output OFF condition
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.
