Avg DIST1 Max DIST Min DIST Avg DIST 1 = Average value of all measured points = Distance to the furthest measuring point = Distance to the closest measuring point Max DIST Min DIST In the factory settings Avg DIST is predefined en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 6/57 Baumer Electric AG Frauenfeld, Switzerland Optional settings OBJECT Selection of bright or dark objects to optimize the measurement results. PRECISION To achieve better precision and resolution, it is possible to alternate between Standard, High and Very High by filtering the output values. FIELD OF VIEW The width of the measuring field can be changed with FIELD OF VIEW. Separate configuration of the single points of the field: LIMIT LEFT, LIMIT RIGHT. This function is required when there are objects in the measuring field that should not be detected. ANALOG OUT Start of measuring range Sdc and end of measuring range Sde can be changed with SCALE OUT. 0V or 4mA then apply for the start of measuring range Sdc. 10V or 20 mA apply for the point at the end of measuring range Sde. Voltage and current output is selected under ANALOG OUT. In addition, the output curve can be inverted under OUTP. SLOPE. DIGITAL OUT The sensor is equipped with a switching output that can be configured as a threshold or as a window via the DIGITAL OUTPUT function. Threshold: As soon as the measuring value is greater than the entered threshold, the switching output will be changed. Window: As soon as the measuring value is outside the entered window, the switching output will be changed. 4 Let's get started The sensor continuously outputs the measuring value in mm to the display and transmits it via the analog output to the control. Alternatively, the measuring value can also be retrieved from the RS485 interface. en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 7/57 Baumer Electric AG Frauenfeld, Switzerland 3 Connection ATTENTION!

Displayed for the edge position are always the values for the object or the reference surface with the 1 smallest distance to “Start of measuring range” . The requirements for the object with respect to the minimum width1 and height1 must be met. NOTE When several objects are in the measuring range, the object with the shortest distance from the start of measuring range is the reference object. Displaying the tilt angle For displaying the tilt angle of the sensor to the reference surface, in the measuring field must not be an object. The output will be ---- for EDGE LEFT RISING of the object. Finding the reference point without a teached reference surface Once an object is within the measuring range, the position of LEFT EDGE RISING and the angle of the surface of the object relative to the axis "End of measuring range"1 are displayed. When moving the object into the direction of the assumed reference point until LEFT EDGE RISING displays 0mm, the reference point is found. 1 According to data sheet chapter 6.1 en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 20/57 Baumer Electric AG Frauenfeld, Switzerland 5.4 MEAS TYPE The MESAX 70 multi-spot can output measured distances in various ways. The measuring value is calculated in mm with analog or RS485 output. NOTE If the MEAS TYPE is changed, SCALE OUT, DIGITAL OUT and FIELD OF VIEW are reset to the default setting. Distance 5.4.1 Avg DIST Average distance to all measuring points. 5.4.2 Max DIST Distance to the furthest measuring point. 5.4.3 Min DIST Distance to the nearest measuring point. en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 21/57 Baumer Electric AG Frauenfeld, Switzerland 5.5 OBJECT To improve sensitivity to dark objects, the exposure time can be increased. This also changes the measuring repetition time. 5.5.1 Object: Bright (Reflectivity > 18%, white-grey) Exposure time 5.5.2 Object: Dark (Reflectivity 6…18%, dark grey-black) Exposure time 5.6 Short (1 ms) Long (3 ms) PRECISION By enabling filtering, the noise can be reduced and thereby the resolution can be increased. Standard High Very high 12 = normal resolution = approx. twice the normal resolution12 = approx. four times the normal resolution12 5.6.1 Influences of the filter PRECISION The higher precision is set, the more measuring speed is reduced (response and the release time are increased). The measuring frequency is not affected by using this filter. PRECISION utilizes a moving median and a moving average filter. Moving Median The median of a finite list of numbers can be found by arranging all the observations from lowest value to highest value and picking the middle one (e.g., the median of {3, 3, 5, 9, 11} is 5). The number of samples stored in the array is called “Sample size” (e.g. {3, 3, 5, 9, 11} = 5 values). When a new sample is added the oldest sample is removed (Moving filter). A sudden change of the measured values will only effect the output after more than half of the samples stored resemble the new value (e.g. sample size=5 -> 3 samples until output is effected). 1 2 According to data sheet chapter 6.1 Dependent upon object to be measured en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 22/57 Baumer Electric AG Frauenfeld, Switzerland The diagram shows the effects of the median (sample size 5). The filter is used to suppress errors. The output changes after a defined number of samples (sample size/2). The measurement frequency is not affected by this filter, but rather the response time. Moving average The output of the moving average filter is the average of all values found in the array with the defined sample size. When a new sample is added, the oldest sample is removed (Moving filter). As visible in the diagram, the moving average softens the output. In contrast to the median filter, values at the output can be values that have never been measured. The measurement frequency is not affected by this filter, but rather the response time. en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 23/57 Baumer Electric AG Frauenfeld, Switzerland Number of samples until the correct value will be output: - In PRECISION mode HIGH, the distance has to be stable for 4 + 16 samples for the output to show the current value. - In precision mode very high, the distance has to be stable for 8 + 128 samples for the output to show the current value. Example Calculation of the response time with measuring frequency 500 Hz, PRECISION = High 1 / 500 Hz = 0.002 ms Median = 7 / 2 (Formula: Samples / 2) = 4 Average = 16 Response time = 0.002 * (4 + 16) = 0.04 s = 40 ms en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 24/57 Baumer Electric AG Frauenfeld, Switzerland FIELD OF VIEW 5.7 The width of the measuring field can be limited with the FIELD OF VIEW function. All measuring values outside the set measuring field are ignored. This is particularly useful if, for example, the measuring field contains an unwanted object that should not be detected. The measuring field is adapted by software so the width of the visible laser beam does not change. Manual limitation of the measuring field 5.7.1 For full flexibility, every value in the measuring field can be individually adjusted. The modified measuring field need not be symmetrical. Even a single limit, e.g. LIMIT LEFT, can be restricted. • LIMIT LEFT • LIMIT RIGHT Left Right 0 mm Reference line (Middle of measuring field) Measuring field limited LIMIT LEFT ( mm) Reference point LIMIT RIGHT ( mm) NOTE The LIVE MONITOR mode can be used to find the reference point. This function displays the LEFT EDGE RISING of objects. Now an object is slowly pushed toward the presumed zero point. The zero point is reached when the value 0 mm is shown on the sensor display. en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 25/57 Baumer Electric AG Frauenfeld, Switzerland 5.7.2 LIMIT LEFT Limitation of the left side of the measuring field in mm, measured from the reference point. 5.7.3 LIMIT RIGHT Limitation of the right side of the measuring field in mm, measured from the reference point. NOTE The measuring field width (Distance LIMIT LEFT to LIMIT RIGHT) must be at least 2 mm. 5.7.4 FIELD OF VIEW "Set maximum values" resets all adjustments of the measuring field to the standard settings (maximum measuring field). en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 26/57 Baumer Electric AG Frauenfeld, Switzerland 5.8 5.8.1 ANALOG OUT SCALE OUT In the factory setting, the analog output runs across the entire measuring range (start of measuring range Sdc - end of measuring range Sde) from 0...10V (voltage mode) or from 4...20mA (current mode). The start and end of the measuring range can be reset with SCALE OUT, reducing the measuring field and changing the calibration curve. The smaller measuring field improves the measurement repetition time, ie, the measuring frequency is increased. *The minimum window size (distance from end of the measuring range Sde - start of measuring range Sdc) must be greater than 5% of the "end of measuring range" value.

It can be defined as a single switching point (threshold) or a window. Pin 4 is activated when the value (point or window) is exceeded or not reached (active high or active low depending on the setting). The switching points can only be placed inside the active, preset measuring field (note SCALE OUT). There is 1 a hysteresis for a reliable switching signal.

By means of special optics, a laser beam is enlarged into a line and projected to the surface of the object to be measured. Using the multi-lens system, the reflected light from this laser line is projected onto a matrix. From this matrix image, a controller calculates the distance to every individual measuring point. The measuring value is calculated in accordance with the selected modus. Thanks to the factory calibration of the sensors, the output of the distance to the object is always in mm. en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 38/57 Baumer Electric AG Frauenfeld, Switzerland 6.2.1 qTarget The measuring field is aligned with the housing reference surfaces at the factory. The beam position in every sensor is in exactly the same spot, which makes planning and sensor replacement very easy. en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 39/57 Baumer Electric AG Frauenfeld, Switzerland Measuring repetition time and response time Object change 6.3 Response time fast 2x measuring repetition time Measuring repetition time Object change Laserexposure 6.3.1 Response time worst case 3x measuring repetition time Measuring repetition time The measuring repetition time (specified in milliseconds) is the time between two exposure times. Measuring repetition time = 1/‘Measuring frequency in Hz‘ Example: Measuring frequency = 100 Hz 1/100 Hz = 0.01 ms Measuring repetition time = 0.01 ms 6.3.2 Response time Response time is called the time in which the sensor has output the new measured value after an object changed his position. Typically it is about 2-3x measuring repetition time. When the position of the object has changed during the exposure time, the response time is the fastest, ie about the 2x measuring repetition time. At the worst case, if the object position has changed shortly after an exposure time, the response time is 3x measuring repetition time. 6.3.3 Response time when using Sync-In If the Sync-In input is High, and then to start a measurement, is set to Low, the sensor starts with the exposure process. This means that if the Sync-In is in use, the response time always is 2x the measuring repetition time. en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 40/57 Baumer Electric AG Frauenfeld, Switzerland 6.4 Object to be measured Smallest detectable object 6.4.2 Distance to the sensor 6.4.1 Smallest detectable object For an object to be reliably detected, it must conform to the minimum object width1. This minimum object width varies with the distance from the sensor. Smallest detectable object close Smallest detectable object far Reflectivity Bright objects are generally easier to detect than dark objects, since they are more reflective. Reflectivity is the percentage relationship between incident and reflected light.

The laser beam of Sensor2 must be outside the measuring field from Sensor1. If it is not possible to prevent several sensors from affecting each other through appropriate installation, the sensors affecting each other can be operated asynchronously by the Sync-In cable. The superordinate control generates the signals for this. HINT Once the Sync-In is set to High (Hold), all output functions are frozen in their last state until the next measurement. en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 44/57 Baumer Electric AG Frauenfeld, Switzerland Measuring if Synch-In low The sensor checks the level of the Sync-In each time before it sends out the laser pulse.

The output is transmitted as a push-pool signal with active high or active low (inverted), depending on the setting. 6.5.4 Alarm output The sensor evaluates the signal level (amount of reflected light) during every measurement cycle. If this level falls below a defined value (signal gain), the alarm output and red LED on the sensor are activated. Reasons for a low signal level: • Signal gain too small • Incorrect mounting angle • Insufficient light reflected from the object • Object outside the measuring field Signal level Signal gain reached Signal gain not reached No object inside the measuring range Red LED Off Blinks (8 Hz) On Alarm output out2 Low Low High RS485 quality bit Valid Low signal No signal The alarm output cannot be adjusted and is triggered by the following situations: • No object in the measuring field • Insufficient signal gain (e.g. with soiling) or or incorrect OBJECT setting. The alarm signal is output as a push-pull signal (active high). NOTE There is no excess gain hysteresis, which is why rapid switching between alarms can occur. 6.5.5 Interface RS-485 No more than 32 sensors may be connected to one bus during operation with RS-485. When the RS-485 interface is activated, the analog output, digital output and alarm output are deactivated or switched as if there was no object in the measuring range.

With the standard deviation it is possible to determine how great the dispersion of values around a mean value is. Broadly speaking, the standard deviation is the average distance of all measured expressions of a characteristic from the mean value. The standard deviation is only useful if you consider measured values which should actually be identical but which vary. For the sensor, this means that an even surface is observed vertically (or with an activated FLEX MOUNT). The standard deviation is then a measure for the unevenness of the surface. All measuring points within the preset field of view are taken into consideration. Remember • The standard deviation is a measure for the dispersion of the height values of all measured profile points in mm. • It can only be used on a plane that is either vertical with respect to the sensor or is parallel to the Flex Mount reference. • The plane must cover the entire field of view in the X direction. 6.8.1 Example This is a profile of 190 points on an even surface as recorded by the sensor before evaluation (height in mm). It is a typical line. The red line represents the mean value, and the green lines each represent 1x standard deviation. The standard deviation indicates how level the measured line is. 6.6 6.55 6.5 6.45 6.4 6.35 6.3 6.25 6.2 6.15 1 7 13 19 25 31 37 43 49 55 61 67 73 79 85 91 97 103 109 115 121 127 133 139 145 151 157 163 169 175 181 187 6.1 Standard deviation: 0.03 mm Max-Min = 0.157mm en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 50/57 Baumer Electric AG Frauenfeld, Switzerland 7 7.1 Safety instructions and maintenance General safety instructions Intended use This product is a precision device and is used for object detection and the preparation and/or provision of measuring values as electrical quantities for a subsequent system.

If the customer makes plug connections to shielded cables, an EMC version of the connectors should be used, and the shield must be connected to the connector housing across a large area. 7.2 Part Identification Explanatory label Certification label Identification label en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 51/57 Baumer Electric AG Frauenfeld, Switzerland Identification label Class 2: Do not stare into beam A Class 1 laser product is defined as safe in normal operations under reasonably foreseeable conditions, including longterm direct viewing of the beam, even when exposure occurs while using telescopic optics. However, direct viewing of a Class 1 laser product may still produce dazzling visual effects, particularly in low ambient light. Certification label Explanatory label Class 1: No risk to eyes or skin Class 2 lasers emit radiation in the visible portion of the spectrum (400 nm to 700 nm). A short-term exposure (duration to 0.25 s) is harmless to the eye. Random short-term impacts (to 0.25 s) do not damage the eye, because the blink reflex can automatically adequately protect the eye against longer irradiation. Class 2 lasers may be used without any additional protection, if it is ensured that for an application no intentional look longer than 0.25 s is required, or (for example, by drug exposure) the blink reflex is suppressed.

Non-compliance with these safety instructions may result in hazardous radiation exposure! ATTENTION! The use of a sensor with a broken front glass or dissolved or detached lens may result in hazardous radiation exposure. 7.5 Cleaning the sensors The laser distance sensors do not require any maintenance, except that the front windows must be kept clean. Dust and fingerprints can impair sensor function. It is normally sufficient to wipe the windows with a clean (!), soft lens cleaning cloth. Alcohol or soapy water can be used in case of severe soiling. The display and the keys must be kept free from dirt and moisture. Water and dirt on the keys can impair their function. en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 53/57 Baumer Electric AG Frauenfeld, Switzerland 8 Error correction and tips 8.1 8.1.1 Examples of sensor setup Simple distance measurement to an object 1.

Power supply 15…28 VDC between pin 2 (+Vs, brown) and pin 7 (GND, blue) • Short circuit at the digital output. Check connection. • Object outside measuring field (near, far or to the side) • Amplitude of the received signal is insufficient (e.g. in case of soiling) • Touch panel locked. Re-enable panel for operation by sliding a finger over the 4 keys from left to right. • RS-485 controls the sensor--> operation via the touch panel not possible at the same time • RS-485 locks the touch keys--> the touch panel was locked via RS-485 and can only be re-enabled with a command via RS-485 • Clean panel. The panel is dirty or wet, which makes it harder to press the keys • The object is not in the measuring range • Bright object, avoid direct reflexes from the transmitter to the receiver • The red visible laser beam does not represent the maximum measuring field If the object is at the edge of this beam it could be outside the measuring range • Move object. The object is outside the measuring field vertically or is in the blind region of the sensor • The object is not in the measuring range • Avoid bright object • Avoid very dark object • Too much ambient light • Check measuring mode setting (MEAS TYPE) Sync-In input is on High--> set to Low en_BA_OM70_MESAX_multi-spot.docx 31.05.2016 14:02/tof V1.10 ANW_81156398 55/57 Baumer Electric AG Frauenfeld, Switzerland 9 Revision history 23.11.2015 26.01.2016 8.04.2016 28.04.2016 31.05.2016 tof tof tof tof tof Manual released in version 1.0 Integrated linearity and definition of response time and measuring repetition time Integrated new article; optimized Laser characteristics Additional information about the working principle of the filter PREZISION New sensor type integrated.
