C MINI-BEAM® Sensors SM31E/SM31R and SM31EL/SM31RL MINI-BEAM Installation and Alignment Proper operation of the sensors requires that they be mounted securely and aligned properly. Excessive movement or vibration can cause intermittent or false operation due to loss of alignment. For maximum mechanical stability, final-mount these sensors in 18-mm holes by their threaded barrels or use a mounting bracket (see page 6). 1) Begin with the emitter mounted securely in place. For small-parts counting applications, stretch a string between the emitter and receiver lenses to ensure that the sensing beam will pass through the center of the sensing location. For less critical applications, the receiver may be initially positioned by line-of-sight placement. Mount the receiver, leaving a means for movement. Opposed Mode Alignment Move receiver to obtain the fastest LED pulse rate. Receiver Emitter Up t gh Ri 2) Apply power to the emitter and receiver, and advance the receiver’s 15-turn GAIN control to maximum (clockwise end of rotation). The GAIN control is clutched at both ends to avoid damage, and will “free-wheel” when either endpoint is reached. If the receiver is “seeing” the emitter’s light beam, the receiver alignment LED should be “on”. Move the receiver up-down-right-left (include angular rotation) to obtain the fastest receiver LED pulse rate. If a pulse is not observable (too fast to count), reduce the GAIN control (counterclockwise rotation) to obtain a countable pulse rate of one to five beats per second. Note: to aid alignment at short ranges, it may help to further reduce the strength of the light signal by temporarily masking the emitter and/or receiver lens with tape or a sheet of paper. 3) Repeat the alignment motions after each GAIN reduction. When you have found the receiver orientation that produces the fastest pulse rate, mount the receiver solidly in that position. Remove any masking material, and increase the receiver GAIN to maximum. Test the system by placing the object to be detected into the sensing position. The receiver LED indicator should go “off”. If it does not go “off”, the cause is probably either “flooding” or “burn-through”. Flooding occurs when a portion of the effective beam passes around the object to be sensed and activates the receiver. Check that the object completely breaks the beam, and that the beam is centered on the object. Add apertures, if necessary, to tailor the effective beam to the size or profile of the object being sensed. Burn-through refers to a portion of the emitter’s light energy passing through a thin or translucent object and activating the receiver. Try sensing at a reduced GAIN setting or consider an alternative sensing scheme. ft Le wn Do Receiver 15 Turn Gain Adjustment and Light/Dark Operate Switch* Gasketed Acrylic Cover “AID” Indicator LED lights when the sensor sees the reflection of its own modulated light and pulses at a rate proportional to the strength of the received light signal * 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. • Minneapolis, U.S.A. page 2 www.bannerengineering.com • Tel: 763.544.3164 MINI-BEAM® Sensors SM31E/SM31R and SM31EL/SM31RL MINI-BEAM DC Sensor Specifications Supply Voltage and Current 10 to 30V dc (10% maximum ripple) at less than 25 mA (exclusive of load) Supply Protection Circuitry Protected against reverse polarity and transient voltages Output Configuration Bipolar: One current sourcing (PNP) and one current sinking (NPN) open-collector transistor Output Rating 150mA maximum each output at 25°C, derated to 100 mA at 70°C (derate ≈1 mA per °C) Off-state leakage current less than 1 microamp Output saturation voltage (PNP output) less than 1 volt at 10 mA and less than 2 volts at 150 mA Output saturation voltage (NPN output) less than 200 millivolts at 10 mA and less than 1 volt at 150 mA Output Protection Circuitry Protected against false pulse on power-up and continuous overload or short-circuit of outputs Output Response Time Sensors will respond to either a “light” or a “dark” signal of 1 millisecond or longer duration, 500 Hz max. 0.3 millisecond response modification is available.
