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. 

|**LED**|**RUN Mode**|**TEACH Mode**|
|---|---|---|
|Solid green|Power is on||
|Flashing green|Sensed light level is approaching sensing<br>threshold<br>3||
|Solid red||Sensor “sees” its own modulated light source; pulse rate is proportional to the<br>received light signal strength<br>4|
|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.

## **Remote Configuration** 

The remote function can be used to configure the sensor remotely or to disable the push button for security. Connect the gray wire of the sensor to ground (0 V dc), with a remote programming switch connected between them. Pulse the remote line according to the diagrams in the configuration procedures. The length of the individual programming pulses is equal to the value T where: 0.04 seconds ≤ “T” ≤ 0.8 seconds

## **Static Teach**

The two sensing conditions may be presented in either order. The condition presented first is the condition for which the output will energize (the “Output ON” target). 

Sensitivity is automatically set (and optimized) when teaching the sensor the ON and OFF conditions. When the push button is clicked, the sensor samples each sensing condition and registers it into memory. After the second sensing condition is registered, the MINI-BEAM Expert automatically sets the sensitivity to the optimum value for the application, and then returns to RUN mode. 

Push button (0.04 seconds ≤ “Click” ≤ 0.8 seconds); Remote line (0.04 seconds ≤ “T” ≤ 0.8 seconds) 

## 1. Access TEACH mode.

||||If the teach is not accepted, the amber LED is on and the red LED pulses|
||||to indicate the relative received signal strength. The sensor returns to its|
||||wait state and is ready for the first sensing condition.|



2. Teach the first sensing condition. 

**NOTE:** The sensor returns to RUN mode if the first TEACH condition is not registered within 90 seconds. TEACH mode may be cancelled before either the first or second condition by holding the push button depressed for more than two seconds. 

## **Enabling or Disabling the Push Button** 

In addition to its programming function, the remote line may be used to disable the push buttons for security. Disabling the push buttons prevents undesired tampering with the sensor configuration settings. 

1. Connect the sensor’s gray wire. 

2. Four-pulse the remote line to enable or disable the push button. 

The sensor toggles between enable and disable settings and returns to RUN mode.
