C MINI-BEAM Sensors SM312LV, SM312LVAG and SM312LP MINI-BEAM Installation and Alignment Proper operation of these sensors requires that they be mounted securely and aligned properly. For best results, final-mount these sensors in an 18 mm hole by their threaded barrel or use one of the available mounting brackets, (see pages 6 - 7). Retroreflective Mode Alignment 1) Begin with the sensor at the desired distance from the retro target and at the Move sensor (or target) to approximate position where it will be mounted. An object at the sensing obtain the fastest receiver LED position should pass through the core of the sensors light beam. pulse rate. 2) Apply power to the sensor, and advance the sensors 15-turn GAIN control to maximum (clockwise end of rotation). If the sensor is seeing the reflected light beam, the alignment LED should be on. Move the sensor up-down- right-left to obtain the fastest receiver LED pulse rate. (alternatively, the retro target may be moved.) If a pulse is not observable (too fast to count), reduce the GAIN control (counterclockwise rotation) to obtain a countable pulse rate. (As an aid to alignment, it may be necessary to further reduce the strength of the light signal by tape-masking a portion of the retroreflective target area.) 3) Repeat the alignment motions after each GAIN reduction. When you have found the sensor orientation that produces the fastest pulse rate, mount the sensor (or reflector) solidly in that position. Increase the receiver GAIN to maximum. Test the system by placing the object to be detected into the sensing position. The indicator should go off. If an LV model sensors indicator does not go off at this point, the sensor is reacting to light reflected from the object (proxing). If proxing occurs, reduce the GAIN setting until the alignment indicator goes 15 Turn off, plus two additional full turns. Remove the object from the sensing Gain Adjustment position and check that the alignment indicator LED comes on and pulses at and Light/Dark a rate of at least two flashes per second. Confirm that the LED goes off when Operate Switch* the object is replaced. Gasketed Acrylic Cover Proxing can be avoided by mounting the sensor so that its light beam is not perpendicular to any flat reflective surface on the object to be detected (an AID Indicator LED Lights when the sensor sees the reflection of its own modulated angle of 10 to 15 degrees is usually sufficient). Also, at distances of a few feet light and pulses at a rate proportional to the or more, using more than one reflector may increase sensing contrast between received light signal. object-present and object-absent. * Note regarding Light/Dark operate switch: Turn switch fully clockwise for light operate (sensor outputs conduct when sensing light is received) Turn switch fully counterclockwise for dark operate (sensor outputs conduct when sensing light is not received) Banner Engineering Corp.
