Sensor Mounting and Alignment MINI-BEAM sensors perform most reliably if they are properly aligned and securely mounted. For maximum mechanical stability, mount MINI-BEAM sensors through 18 mm diameter holes by their threaded barrel (where available), or use a mounting bracket. A complete selection of mounting brackets is available. Visit www.bannerengineering.com or contact the factory for information on mounting options. Begin with line-of-sight positioning of the MINI-BEAM sensor to its emitter (opposed-mode sensing) or to its target (all other sensing modes). When using a retroreflective sensor, the target is the retroreflector (“retro target”). For diffuse or convergent sensing modes, the target is the object to be detected. Apply power to the sensor (and to the emitter, if using the opposed mode). Advance the 15-turn Gain control to maximum (clockwise end of rotation) using a small flat-blade screwdriver. The Gain control is clutched at both ends to avoid damage and will “free-wheel” when either endpoint is reached. If the MINI-BEAM sensor is receiving its light signal, the red LED Alignment indicator will be ON and flashing at a rate proportional to the signal strength (faster = more signal). Move the sensor (or retro target, if applicable) up-down-right-left (including angular rotation) to find the center of the movement zone within which the LED indicator remains ON. Reducing the Gain setting reduces the size of the movement zone for more precise alignment. Repeat the alignment motions after each Gain reduction. When optimum alignment is achieved, mount sensor(s) (and the retro target, if applicable) solidly in that position. Increase the Gain to maximum. Test the sensor by placing the object to be detected in the sensing position, then removing it. The Alignment indicator LED should come ON when the sensing beam is established (Light condition) or be ON when the beam is broken (Dark condition). If the Alignment indicator LED stays ON for both sensing conditions, consider the follow- ing tips for each sensing mode. Opposed Mode Alignment Object Emitter Receiver “Flooding” occurs when a portion of the sensing beam passes around the object to be sensed. “Burn-through” occurs when a portion of the emitter’s light energy pass- es through a thin or translucent object, and is sensed by the receiver. To correct either problem, do one or more of the following to reduce the light ener- gy: • Reduce the Gain adjustment on the receiver. • Add an aperture to one or both lenses. (MINI-BEAM apertures, available from Banner, fit neatly inside the lens assembly.) • Intentionally misalign the emitter and receiver. Note: • Light condition: sensor output is ON when there is no object in beam • Dark condition: sensor output is ON when there is an object in beam MINI-BEAM dc-Voltage Series P/N 69943 rev.
