See page 5 for more information. iii) A model with a QD connector requires an accessory mating cable. See page 8 for more information. Printed in USA P/N 03561L7B MINI-BEAM(R) Sensors SMA31E/SM2A31R and SMA31EL/SM2A31RL 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 Receiver Emitter Up ht Rig 2) Set the receiver to light-operate mode. 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 end point 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 locate the center of the movement range within which the LED stays lit. Reducing the GAIN setting will restrict the range of motion and allow precise positioning. 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 center of the movement range, 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, alignment is complete, and you may now switch the sensor to darkoperate if the application requires it.) If the LED does not go "off", the cause is probably either "flooding" or "burnthrough". 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. page 2 ft Le wn Do Receiver 15 Turn Gain Adjustment and Light/Dark Operate Switch* Gasketed Acrylic Cover Red LED lights when the sensor's output is conducting. * Note regarding Light/Dark operate switch: * Turn switch fully clockwise for light operate (sensor outputs conduct when object is absent) * Turn switch fully counterclockwise for dark operate (sensor outputs conduct when object is present and blocking light beam) MINI-BEAM(R) Sensors SMA31E/SM2A31R and SMA31EL/SM2A31RL MINI-BEAM AC Product Specifications Supply Voltage and Current 24 to 240V ac (50/60 Hz), 250V ac max Supply Protection Circuitry Protected against transient voltages Output Configuration SPST SCR solid-state relay with either normally closed or normally open contact (light/dark operate selectable); 2-wire hookup Output Rating Minimum load current 5 mA; maximum steady-state load capability 300 mA to 50C ambient (122F) 100 mA to 70C ambient (158F) Inrush capability 3 amps for 1 second (non-repetitive); 10 amps for 1 cycle (non-repetitive) Off-state leakage current less than 1.7 mA rms On-state voltage drop 5 volts at 300 mA load, 10 volts at 15 mA load Output Protection Circuitry Protected against false pulse on power-up Output Response Time 2 millisecond on and 1 millisecond off Repeatability 0.3 milliseconds Adjustments LIGHT/DARK OPERATE select switch, and 15-turn slotted brass screw GAIN (sensitivity) adjustment potentiometer (clutched at both ends of travel).
