Overview
Status indicators
Normal operation of the MINI-BEAM Expert is called RUN mode. The two LED indicators (bi-color
Green/Red and Yellow) operate as follows in RUN mode and TEACH mode:
If contrast is marginal, the bi-color indicator will flash green (to indicate instability). Reprogramming or
realigning the sensor, or cleaning the sensor or fiber lenses may solve a problem with stability.
Remote Configuration
The remote function may be used to configure the sensor remotely or to disable the push button for
security. Connect the gray wire of the sensor to ground (0V 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:
0.04 seconds ≤ “T” ≤ 0.8 seconds
Troubleshooting
The MINI-BEAM Expert’s Power LED may begin to alternate flashing red/green; this indicates a
microprocessor memory error. If it occurs, try reteaching the sensor, or try cycling power ON and OFF,
then reteaching the sensor. If this does not solve the problem, or if it occurs frequently, replace the
sensor.

Bi-Color
Green/Red
ON Green: Power is ON
Flashing Green: Sensed light level is
approaching sensing
threshold*
ON Red: Sensor “sees” its own modulated
light source; pulse rate is
proportional to the received light
signal strength**
Yellow
ON: Outputs conducting
OFF: Outputs not conducting
ON: Ready to TEACH output ON condition
OFF: Ready to TEACH output OFF condition
* This is the Stability indicator, which signals when maintenance, realignment, or reconfiguration is needed
during RUN mode.
** The faster the pulse rate, the stronger the light signal.

Output Configuration
Bipolar: One current sourcing (PNP) and one current sinking (NPN) open-
collector transistor
Output Rating
150 mA max. each output at 25° C, derated to 100 mA at 70° C
