Contamination of the lenses leads to impairment or failure of the function. optoNCDT 1302 Page 8 Safety -- Operating temperature: 0 to +50 °C (+32 to +122 °F) -- Storage temperature: -20 to +70 °C (-4 to +158 °F) -- Humidity: 5 - 95 % (no condensation) -- Pressure: atmospheric pressure -- EMC: acc. to EN 61326-1:2006-10 DIN EN 55011: 2007-11 (Group 1, Class B) EN 61000-6-2: 2006-03 i 2. The protection class is limited to water (no penetrating liquids or similar)! Laser Class The sensors operate with a semiconductor laser with a wavelength of 670 nm (visible/red). The laser emits a permanent beam. The maximum optical power is ≤ 1 mW. The sensors are classified for Laser Class 2 (II). The laser warning labels for Germany have already been applied. Those for other non German-speaking countries an IEC standard label is included in delivery and the versions applicable to the user’s country must be applied before the equipment is used for the first time. Attach the following warning labels on the sensor housing front side: LASER RADIATION Do not stare into the beam CLASS 2 LASER PRODUCT IEC 60825-1: 2007 P≤1mW; =670 nm IEC label i optoNCDT 1302 Only for USA If both warning labels are disguised in operation mode the user must add additional warning labels. Page 9 Laser Class During operation of the sensor the pertinent regulations acc. to EN 60825-1 on „radiation safety of laser equipment“ must be fully observed at all times. The sensor complies with all applicable laws for the manufacturer of laser devices. Do not look directly into the laser beam! Possible injury of the eyes. Close your eyes or turn away promptly if laser radiation strikes your eyes. teach in laser on state optoNCDT LASER RADIATION Do not stare into the beam CLASS 2 LASER PRODUCT IEC 60825-1: 2007 P≤1mW; =670 nm Laser spot Fig. 1 True reproduction of the sensor with its actual location of the warning labels Laser operation is indicated by LED. Although the laser output is low looking directly into the laser beam must be avoided. Due to the visible light beam eye protection is ensured by the natural blink reflex. The housing of the optical sensors optoNCDT1302 may only be opened by the manufacturer, see Chap. 14.. For repair and service purposes the sensors must always be sent to the manufacturer. optoNCDT 1302 Page 10 Functional Principle, Technical Data 3. Functional Principle, Technical Data 3.1 Functional Principle The sensor uses the principle of optical triangulation, that is a visible, modulated point of light is projected onto the target surface. A LED on the sensor indicates: -- In range -- Out of Range (upper and lower range values), poor target (unfit or no object) -- Mid range The sensor outputs analog or digital values. LASER RADIATION Do not tare into the beam C ASS 2 LASER PRODUCT IEC 60825-1: 2007 P≤1mW; =670 nm SMR The controller calculates the measured value from the CCD-array. An internal closed-loop control enables the sensor to measure against different surfaces. laser on state optoNCDT Measuring range The diffuse element of the reflection of the light spot is imaged by a receiver optical element positioned at a certain angle to the optical axis of the laser beam onto a high-sensitivity resolution element (CCD), in dependency on distance. teach in Current output Digital value 3.75 mA 16372 4 mA (SMR) 40 12 mA (MR) 2048 20 mA (EMR) 4055 3.75 mA 16374 Fig. 2 Definiton of terms, output signal SMR = Start of measuring range | MR = Midrange | EMR = End of measuring range optoNCDT 1302 Page 11 Functional Principle, Technical Data 3.2 Functions 3.2.1 Fitting the Measurement Range The analog measuring range can be reduced with aid of the “Teach“ function, see Chap. 6.2. This enables you to scale only a part of the measuring range to the full scale current output. Thus the resolution of analog evaluation systems like displays or PLCs will be used better. 3.2.2 Peak Select For measurements on mirroring or transparent surfaces like glass plates or plastic layers spurious reflections from the front or rear side can be suppressed by command, see Chap. 8.3.14. 3.2.3 Trigger, Time-based Measurement Value Output Single measurements can be output via the trigger input. You can also output the measurements in a programmable timing period, see Chap. 8.3.10. 3.2.4 Error Behavior The sensor may replace or hold up to 99 consecutive errors by the last valid value. In addition, all error values at the analog output can be replaced by the last valid value. Details about the behavior of the analog output, see Chap. 8.3.11. 3.2.5 Averaging The sensor enables an averaging of the measured values with the median or moving average, before they are output. This does not reduce the measurement rate. optoNCDT 1302 Page 12 Functional Principle, Technical Data 3.2.6 Video Signal Intensity The sensor can use different peaks in the CCD array for displacement measuring. This function is auxiliary, if the sensor measures against glass or transparent targets, see Chap. 8.3.14. CCD array SMR Displacement 1 Displacement 2 Measuring range Fig. 3 Video signal 3.2.7 Programmable Search Threshold Intensity The sensor can use different thresholds to detect a valid peak in the CCD array for displacement measuring. Highest Higher than Standard Standard Lower than Standard CCD array optoNCDT 1302 Parameters, see Chap. 8.3.15 for parameter setting: -- lower than standard -- Standard -- higher than standard -- highest i Changing the threshold from factory default (standard) may influence linearity and resolution.

The minimum pulse duration is 30 ms, see Chap. Fig. 10. This external input can be configured as a trigger input to output the measurements also. If pin 9 is connected with pin 12 measurements are output at the serial or analog output. The maximum trigger frequency is 250 Hz.

Page 20 Operation 6. Operation 6.1 Getting Ready for Operation Install and assemble the optoNCDT1302 in accordance with the instructions set out, see Chap. 5.1 and connect it with the indicator or monitoring unit and the power supply, having full regard to the connection instructions set out, see Chap. 5.2. The laser diode in the sensor can only be activated if -- the input “Laser on/off“ (Pin 9) or -- the black wire in the PC1402 sensor cable is connected to GND. Once the operating voltage has been switched on the sensor runs through an initialization sequence. This is indicated by the momentary activation of the “State” LED. If initialization has been finished, the sensor transmits the info string once in ASCII format via the serial interface independent of the selected interface. The initialization including the info string transmission takes up to 5 seconds. Within this period, the sensor neither executes nor replies commands. To be able to produce reproducible measurements the sensor typically requires a start-up time of 15 minutes. Once this has elapsed the sensor will be in measurement mode and, in accordance with the factory settings, only the “State“ LED is illuminated. If the “State“ LED is off, this means that -- either there is no operating voltage or -- the laser has been switched off. Operating Voltage -- Nominal value: 24 VDC (11 ... 30 V, max. 50 mA). -- Use the power supply unit for measurement instruments only, and not for drive units or similar sources of pulse interference at the same time. Switch on the power supply unit, if wiring is done. optoNCDT 1302 Page 21 Operation 6.2 ing Output Scal- The “teaching” scales the analog output (4 to 20 mA) for a part of the measuring range. This allows you to optimize the resolution for the analog measurement range. Only the current and error output will be affected by the 2 point calibration. Therefore you define a new start and end for the measurement range. This “teaching” procedure can be performed live via the select key or via pin 9 of the connector. i You can use the error output with a user defined output scaling, see Chap. 5.2.3, as a programmable limit switch. 20 mA 4 mA 3 mA SMR EMR Measuring range Measuring object Digital value 16372 LED “state” 0 40 4055 Measuring object within range Error 16368 16374 Error Error output 20 mA Analog output User defined characteristic 4 mA 3 mA SMR Digital value 16372 LED “state” Error Error output optoNCDT 1302 Default characteristic Analog output 16380 Teach 1 Teach 2 1229 3073 EMR 16382 16374 Error Measuring object within range Page 22 Operation 20 mA Analog output User defined characteristic 4 mA 3 mA Teach 2 SMR Teach 1 EMR Measuring object Digital value LED “state” 16372 16380 1229 3073 Error Error output 16382 16374 Error Measuring object within range Fig. 7 Reverse user defined characteristic The minimum distance of the teach values 1/2 to one other is 10 % of the measurement range.

Implemented averaging methods in the sensor: -- Moving average -- Median The purpose of averaging is to: -- Improve the resolution -- Eliminate signal spikes -- “Smooth out“ the signal. Averaging has no effect on linearity. A combination of the two averaging methods is not possible. The averaging is recommended for static measurements or slowly changing measurement values. 6.3.1 Averaging Number N In every measurement cycle (at a measurement rate of 750 Hz every 1.3 ms) the internal average is calculated anew. The averaging number N indicates the number of consecutive measurement values to be averaged in the sensor. Averaging does not affect the measurement rate or data rates in digital measurement value output. 6.3.2 Moving Average (Default Setting) The selected number N of successive measurement values (window width) is used to generate the moving average value M gl on the basis of the following formula: N MW (k) M gl = optoNCDT 1302 k=1 N MW = Measuring value, N = Averaging number, k = Running index M gl = Averaging value respectively output value Page 26 Operation Mode: Each new measurement value is added and the first (oldest) measurement value from the averaging process (from the window) taken out again. This results in short transient recovery times for jumps in measurement values. Example: N = 4 ... 0, 1, 2, 2, 1, 3 ... 1, 2, 2, 1, 3, 4 2, 2, 1, 3 = M gl (n) 4 i 2, 1, 3, 4 = M gl (n+1) 4 Measurement values Output The moving average in the optoNCDT1302 can only be generated for up to a maximum of 128 values. 6.3.3 Median The median is generated from a pre-selected number of measurement values. To do so, the incoming measurement values (3, 5, 7 or 9 measurement values) are resorted again after every measurement. The average value is then given as the median. In generating the median in the controller, 3, 5, 7 or 9 measurement values are taken into account, i.e. there is never a median of 1. This permits individual interference pulses to be repressed, but the measurement value curve is not smoothed to any great extent. Example: Average from five measurement values ... 0 1 2 4 5 1 3 Sorted measurement values: 1 2 3 4 5 ... 1 2 4 5 1 3 5 optoNCDT 1302 Sorted measurement values: 1 3 4 5 5 Median (n) = 3 Median (n+1) = 4 Page 27 Operation 6.4 Measurement Rate and Output Rate The measurement rate defines the number of measurements performed by the sensor per second. The measurement rate is 750 Hz. The output rate gives the actual number of measurement values at the sensor output per second. The maximum output rate can never exceed the measurement rate. Output Current Maximum output rate Measurement rate RS422 Output rate £ Measurement rate; Dependent on the transmission rate (baud rate) and data format (ASCII code). The sensor continues to measure internally but holds back the output until the last measurement value has been issued in full. The next measurement value is the last valid value, with other values between being lost. Fig. 2 Output rates for the output types Calculation of the output rate using the RS422 serial interface: Abbreviations used: Output rate = Measuring rate / n n = Partial factor int = Integral part of ( ) b = Byte/measurement value (binary format b=2, ASCII b=6) MR = Measurement rate [Hz] n = int (b * 11 * MR / BR) + 1 BR = Baud rate [Baud] Example: Measurement rate = 750 Hz, ASCII-Format (b=6), Baud rate = 115200 Baud --> n = int (0.43) + 1 = 1 --> Output rate = 750 Hz / 1 = 750 Hz. optoNCDT 1302 Page 28 Operation 6.5 Timing The controller operates internally with real time cycles in a pipeline mode: 1. Exposure: Charging the image detector in the receiver (measurement). 2. Reading: Reading out of the imaging device and converting into digital data. 3. Computation: Measurement computation. 4. Controlling. The output through the analog and digital interface starts with the beginning of every new cycle. The analog value and digital switch outputs are updated immediately and the digital output starts with the start bit. Each cycle takes 1.3 ms at a measuring rate of 750 Hz. The measured value N is available after each cycle with a constant lag of four cycles in respect to the real time event. The delay between the input reaction and the signal output is therefore 2 up to 2.7 ms. The processing of the cycles occurs sequentially in time and parallel in space (pipelining, see Fig. 12). This guarantees a true constant real time data stream. Cycle 1. 2. 3. 4. 5. 6.

Fig. 12 Sensor timing i The sensor needs time until measuring values are available according to the set averaging number N. optoNCDT 1302 Page 29 Operation 6.6 Triggering The ILD1302 measurement output is controllable through an external signal on the trigger input. Therefore the external input “Teach in“ must be configured for triggering, see Chap. 8.3.13. This can be done with the “ILD1302 Tool“ (“Configuration“ > “General Settings“ > “Digital Input: trigger acquisition“) also. Basics, procedure: -- The sensor measures and calculates also, if no trigger pulses are pending. -- The data output starts with a falling edge of the trigger signal. -- Sensor outputs the measurement value with a delay TT of 1.4 up to 2 ms. -- A new trigger pulse can be sent. +5 V Trigger signal Pin 9 t N Non-pulse period t I Pulse interval T T Delay time High +2 V +0.8 V 0V Low t N > 5 µs Output Value 1 T T = 2,7 ... 4 ms Fig. 13 Timing Time tI> TT T T = 2.7 ... 4 ms Value 2 T T = 2,7 … 4 ms true for a measurement rate of 750 Hz and a baud rate of 115.200 Baud Maximum trigger rate: appr. 250 Hz You get a digital measurement value on the output for each trigger signal, see Chap. 8.3.8, see Chap. 8.3.9 (data output). The analog output is actualized with any trigger signal, if you use the analog output. i optoNCDT 1302 An averaging of the measuring values has no effect on the delay time TT. Consider certainly, that the controller needs time for the averaging, until measuring values are available according to the set averaging number N. Page 30 Measurement Value Output 7.

Each command packet has a header consisting of two 32 bit words followed by the command and, if required, other data as well. The top two bits (No. 31 and 30) are always “0“ in the transmitted command. optoNCDT 1302 Page 36 Serial Interface RS422 8.3.2 Overview Information command 0x20490002 Chap. 8.3.3 0x204A0002 Chap. 8.3.4 Average 0x207F0004 Chap. 8.3.5 Measurement value output 0x20760002 Chap. 8.3.6 0x20770002 Chap. 8.3.7 0x20F40003 Chap. 8.3.9 0x20F50003 Chap. 8.3.10 Switch output settings 0x20900003 Chap. 8.3.8 Speed 0x20800003 Chap. 8.3.12 Error output (analog output) 0x20810003 Chap. 8.3.11 GET_INFO GET_SETTINGS Shows sensor data Shows sensor settings SET_AV Sets average type and value DAT_OUT_OFF DAT_OUT_ON SET_OUTPUTMODE SET_OUTPUTTIME_MS Stops measurement value output Permanent measurement value output Output mode Output time in ms SET_OUTPUT_CHANNEL Output: current or RS422 SET_BAUDRATE 115.2 / 57.6 / 38.4 / 19.2 / 9.6 kBaud SET_ANALOG_ERROR_HANDLER Behavior of the analog output in the case of an error External input 0x20F80003 Chap. 8.3.13 SET_EXT_INPUT_MODE Switching off the laser (external) 0x20870002 Chap. 8.3.16 LASER_ON 0x20860002 Chap. 8.3.16 LASER_OFF Measurement value data format 0x20880003 Chap. 8.3.17 ASCII_OUTPUT Key lock 0x20600003 Chap. 8.3.18 SET_KEYLOCK optoNCDT 1302 Scaling, triggering Switches the laser on Switches the laser off Options: ASCII / Binary Key enabled / locked / auto lock Page 37 Serial Interface RS422 Reset 0x20F10002 Chap. 8.3.20 0x20F00002 Chap. 8.3.19 Memory mode 0x20F70003 Chap. 8.3.21 Scaling values 0x20F90004 Chap. 8.3.22 0x20FA0002 Chap. 8.3.23 Search algorithm 0x20FB0003 Chap. 8.3.14 Threshold 0x20FC0003 Chap. 8.3.15 8.3.3 SET_DEFAULT RESET_BOOT Reset to default factory settings Reboot the sensor SET_SAVE_SETTINGS_MODE Volatile / nonvolatile SET_TEACH_VALUE RESET_TEACH_VALUE Sets T1 + T2 0 ... 16368 Sets T1 = 0 / T2 = 16368 SET_PEAKSEARCHING First peak, last peak, global maximum SET_THRESHOLD Lower than standard, standard, higher than standard, highest Reading the Sensor Parameters, GET_INFO Name:GET_INFO Description: Format: 31 optoNCDT 1302 Supplies the info string.

Instructions for Operating 9.1 Reflection Factor of the Target Surface In principle the sensor evaluates the diffuse part of the reflected laser light, see Fig. 18. Laser beam Laser beam Laser beam 2 Ideal diffuse reflection Direct mirror reflecion Real reflecion Fig. 18 Reflection factor of the target surface A statement concerning a minimum reflectance is difficult to make, because even a small diffuse fraction can be evaluated from highly reflecting surfaces. This is done by determining the intensity of the diffuse reflection from the CCD array signal in real time and subsequent compensation for intensity fluctuation, see Chap. 3.2. Dark or shiny objects being measured, e.g. black rubber, may require longer exposure times. The exposure time is dependent on the measurement rate and can only be increased by reducing the sensor’s measurement rate. 9.2 Error Influences 9.2.1 Light from other Sources Thanks to their integrated optical interference filters the optoNCDT1302 sensors offer outstanding performance in suppressing light from other sources. However, this does not preclude the possibility of interference from other light sources if the objects being measured are shiny and if lower measurement frequencies are selected. Should this be the case it is recommended that suitable shields be used to screen the other light sources. This applies in particular to measurement work performed in close proximity to welding equipment. optoNCDT 1302 Page 62 Instructions for Operating 9.2.2 Color Differences Because of intensity compensation, color difference of targets affect the measuring result only slightly. However, such color differences are often combined with different penetration depths of the laser light into the material. Different penetration depths then result in apparent changes of the measuring spot size. Therefore color differences in combination with changes of penetration depth may lead to measuring errors. 9.2.3 Temperature Influences When the sensor is commissioned a warm-up time of at least 20 minutes is required to achieve uniform temperature distribution in the sensor. If measurement is performed in the micron accuracy range, the effect of temperature fluctuations on the sensor holder must be considered. Due to the damping effect of the heat capacity of the sensor sudden temperature changes are only measured with delay. 9.2.4 Mechanical Vibrations If the sensor should be used for resolutions in the μm range, special care must be taken to ensure stable and vibration-free mounting of sensor and target. 9.2.5 Movement Blurs If the objects being measured are fast moving and the measurement rate is low it is possible that movement blurs may result. Always select a high measurement rate for high-speed operations, therefore, in order to prevent errors. 9.2.6 Surface Roughness In case of traversing measurements a surface roughness of 5 μm and more leads to an apparent distance change (also-called surface noise). However, they can be dampened by averaging, see Chap. 6.3. 9.2.7 Angle Influences Tilt angles of the target both around the X and the Y axes of less than 5 ° only have a disturbing effect with surfaces which are highly reflecting. Tilt angles between 5 ° and 15 ° lead to an apparent distance change of approx. 0.12 ... 0.2 % of the measuring range, see Fig. 19. Tilt angles between 15 ° and 30 ° lead to an apparent distance change of approx. 0.5 % of the measuring range. These influences must be considered especially when scanning structured surfaces. In principle the angle behavior in triangulation also depends on the reflectivity of the target. optoNCDT 1302 Page 63 Instructions for Operating teach n laser on state optoNCDT LASER RAD ATION Angle X-axis % Y-axis % ±5 ° typ. 0.12 typ. 0.12 ±15 ° typ. 0.2 typ. 0.2 ±30 ° typ. 0.5 typ. 0.5 Do not ta e i to the beam C ASS 2 LASER PRODUCT EC 6082 - : 2007 P≤1mW; =670 nm Y-axis X-axis tilting < triangulation angle Angle Angle Fig. 19 Measurement errors through tilting with diffuse reflection 9.3 Optimizing the Measuring Accuracy Color strips Direction of motion select In case of rolled or polished metals that are moved past the sensor the sensor plane must be arranged in the direction of the rolling or grinding marks.

Do not forget to save the settings made. Disconnect or connect the D-sub connection between RS422 and USB converter when the sensor is disconnected from power supply only. Page 67 Software Support with MEDAQLib 12. Software Support with MEDAQLib The Micro-Epsilon Data Acquisition Library offers you a high level interface library to access optoNCDT laser sensors from your Windows application in combination with -- RS422/USB converter (optional accessory) and a suitable PC1402-3/D-SUB/9pol cable or -- PC1402-3/USB/IND cable or -- IF2008 PCI interface card and PC1402-3/IF2008 cable into an existing or a customized PC software. You need no knowledge about the sensor protocol to communicate with the individual sensors. The individual commands and parameters for the sensor to be addressed will be set with abstract functions. MEDAQLib translates the abstract functions in comprehensible instructions for the sensor. MEDAQLib -- is a DLL/LIB usable for C, C++, VB, Delphi and many other Windows programming languages, -- supports functions to talk to the sensor, -- hides the details on how to talk to the communication interface (RS232,RS422,USB,TCP), -- hides the details of the sensor protocol, -- converts the incoming data to „expected data values“, -- provides a consistent programming interface for all Micro-Epsilon sensors, -- provides many programming examples many different programming languages. -- the interface is documented in a large *.pdf file.
