While aligning sensorheads, the more stability indicators light up, the more reliable detection can beobtained. If either sensor head moves out of position, do all adjustments, including beamalignment, from the beginning.Refer to the instruction manual of LA-305 for more details of beam alignment of sensor heads Calibrating analog output The analog voltage output relates to the span and the shift adjustments as in How to calibrate the output into 1 to 5V1. Block the whole beam to enter into thedarkest condition and set the output at1V with the shift adjuster.2. Allow the whole beam to be received toenter into the lightest condition and setthe output at 5V with the span adjuster.3. For more accurate calibration, repeat 1and 2.5V1VSpanadjustmentShiftadjustmentDarkestconditionLightestconditionIncidentbeamintensityAnalog output㧨Explanation㧪࡮(e.g.) Wire detectionAWireCollimated beamBC Incident beam width = A + C Interrupted beam width = B Lightest condition: The entire beam is received. Darkest condition: The entire beam is blocked.Further use of shift adjuster If you want to change the output voltage value after the calibration, the shiftadjuster enables you to shift the analog voltage up or down within about ±0.5V.(e.g.) To shift the analog voltage from 2.51V to 3V with a certain amount of beam blockageޕCollimated beamSensing objectEmitterReceiver Darkest conditionSetting conditionLightest conditionPrevious1Vto2.51Vto5VSubsequent1.49Vto3Vto5.49V(Application) When two sensor heads are used for width measurement the shift adjuster caneliminate the need to move the sensor heads during set-up.Reference widthCollimatedbeamCollimatedbeamSensing objectEmitter ReceiverEmitter Receiver Up to now, the sensor heads have had to be locatedat the exact positions with respect to the referenceobject to measure at the criterion of 3V, center of 1to 5V. However, even a simulated center is easilyobtained by the shift adjustment, without anyrealignment.Note: To make the whole beam balanced between the lightestand darkest conditions, the sensor heads should be posi-tioned where the sensor generates 3V with the beam halfblocked. Adjusting HIGH & LOW output levels (Two independent outputs)HIGH output threshold level Block as much of the beam for which you wantthe HIGH output. Turn the HIGH adjuster to justbefore the point where the HIGH operation indi-cator lights up. The threshold level increases asthe adjuster is turned clockwise.LOW output threshold level Again, block as little of the beam for which youwant the LOW output. Turn the LOW adjuster tojust before the point where the LOW operationindicator lights up. The threshold level increasesas the adjuster is turned clockwise.$?!@ QYZQ[\] #^ _LOWoutputlevelHIGHoutputlevelONOFFONOFFDarkestconditionLightestconditionIncidentbeamintensityComparativeoutput (HIGH)Comparativeoutput (LOW)HighLow Analog voltage6 MAJOR SPECIFICATIONSDesignation ` ^ 㨯 Model No. LA-A1 LA-A1PApplicable sensor head LA305㧔Note)Supply voltage 12 to 24V DC±10% Ripple P-P 10% or lessCurrent consumption 120mA or less (including sensor heads)Comparative outputs(HIGH,LOW)NPN open-collector transistor PNP open-collector transistorMaximum sink current: 100mAApplied voltage: 30V DC or less(between comparative outputand 0V)Residual voltage: 1.5V or less(at 100mA sink cur-rent)0.5V or less(at 16mA sink cur-rent)Maximum sink current: 100mAApplied voltage: 30V DC or lessResidual voltage: 1.5V or less(at 100mA source cur-rent )0.5V or less(at 16mA source cur-rent)Response time 0.5ms or lessOutputoperationHIGH OUT: ON when the received beam level is equal or lower thanOver-dark levelLOW OUT: ON when the received beam level is equal or higher thanUnder-dark levelShort-circuitprotection IncorporatedAnalog outputAnalog voltageOutput voltage: 1V (Darkest) to 5V (Lightest)\" " !Slew rate 8V/ms or moreTemperaturecharacteristics 0.05%F.S./͠ or lessAmbient temperature 0 to +50͠ (No dew condensation), Storage: -20 to +70͠Ambient humidity 35 to 85% RH, Storage: 35 to 85% RHMaterial Enclosure: Heat-resistant ABS, Terminal cover: Heat-resistantABSFront cover: PolycarbonateCable 0.22mm2 (Shield wire:0.15mm 2 ) 7-core composite cabtyre, 2m longAccessory Adjusting screwdriver: 1 pc.Note: Refer to the instruction manual of LA-305 for more details.7 CAUTIONSMake sure to use the exclusive sensor head LA-305 & # _ This product has been developed / produced for industrial use only. Make sure that the power supply is off while wiring. Take care that wrong wiring will damage the sensor. Verify that the supply voltage variation is within the rating. If power is supplied from a commercial switching regulator, ensure that theframe ground (F.G.) terminal of the power supply is connected to an actualground. In case noise generating equipment (switching regulator, inverter motor,etc.) is used in the vicinity of this product, connect the frame ground (F.G.)terminal of the equipment to an actual ground. Do not run the wires together with high-voltage lines or power lines or putthem in the same raceway. This can cause malfunction due to induction. Extension up to total 50m, or less, is possible with 0.22mm 2 , or more,cable.Use a shielded cable for extension of the analog output cable. In case of using this product as a CE marking conformity product, cableextension of the power wire and I/O wire must be wthin 30m. ! "#the output until stabilized. Make sure that stress by forcible bend or pulling is not applied directly to thesensor cable joint. This sensor is suitable for indoor use only. Do not use this sensor in places having excessive vapor, dust, etc., or where itmay come in direct contact with water, or corrosive gas Take care that the sensor does not come in direct contact with water, oil,grease, organic solvents, such as, thinner etc., strong acid or alkaline. Make sure to mount the terminal cover8 INTENDED PRODUCTS FOR CE MARKING The models listed under “ 6 MAJOR SPECIFICATIONS” come withCE Marking. As for all other models, please contact us.
