Troubleshooting

If the MINI-BEAM Expert’s Power LED alternately flashes red/green, this indicates a microprocessor memory error. To clear

the error, re-teach the sensor or cycle the power ON and OFF and re-teach the sensor. If this does not solve the problem,

or if it occurs frequently, replace the sensor.

Retroreflective Targets

Banner offers a wide selection of high-quality retroreflective targets. See your current Banner Engineering Corp catalog for

complete information on available models. Sensing range will vary, according to the retroreflector’s efficiency and

reflective area.

•

For long-range applications: model BRT-77X77C reflector provides a range up to 2 m (6.5').

•

For clear object detection (low-contrast applications): reflector model BRT-2X2 is recommended; one comes

bundled with each SME312LPC(QD) sensor.

•

Polarized sensors require corner-cube type retroreflective targets only; reflective tape is not recommended.

Before installing retroreflective tape, clean the mounting surface with an isopropyl alcohol wipe.

Optional brackets for mounting reflective targets are available. See the Accessories section of your current Banner catalog

or our website at www.bannerengineering.com.
