反射式激光对射使用说明书
反射式激光探测器使用说明第一章技术特点说明艾礼富-维安达斯系列反射式激光探测器（发明专利号：ZL.201520316071.2)采用808nm不可见光作为探测光源（也可以定做650nm红色可见激光），利用激光源高度集中的特性，通过与配套的反射板配合，将激光发射器和激光接收器设计在同一个探测器上，达到对射式激光探测器一样的应用效果；可广泛应用于不方便两侧布线或不方便取电的通道、厂区入口、铁路、公路、河边等场所的入侵防范，或者交通检测、计量检测等场所；反射式激光探测器内部采用本公司专利技术的自动光能量记忆技术（ALM）和AGC自动增益控制电路，使得维安达斯系列激光探测器可广泛应用于各种复杂环境，彻底杜绝由于小动物或者其他环境因素（风霜雨雪雾等）引起的误报。
激光作为一种能量高度集中的光源，早期应用于航空航天及军工设施中；维安达斯系列激光入侵探测器采用军工级的激光发射和接收器件作为探测器的主要部件，使产品在探测距离，抗干扰，稳定性各方面都优于传统的主动红外红外对射、红外光栅等探测器，因此一经面世即受到各界用户的广泛应用和肯定，目前已经成功应用于机场、地铁、国界线、大型项目重点设备保护现场、各种训练场、工厂周界、养殖场等，是现代安防领域重要的入侵探测器。
技术特点和优势：1、采用不可见激光源与反射板结合，形成对射式激光探测器一样的可靠的隐形防范效果；2、采用单边布线、单边供电方式，施工成本和难度大大降低；3、由于激光射线能量高度集中，抗自然界环境变化引起的干扰能力超强，探测器经安装调试合格后，工作状态非常稳定；4、当探测器具有两个光束回路以上时，可根据现场情况选择单个回路阻断报警模式或者两个回路同时阻断报警模式，可杜绝小体积的物体经过探测器隐形防线之间可能引起的报警；5、可广泛适用于不方便两侧布线或取电的通道、出入口、铁路、公路、河边等场所的入侵防范，也可用于交通检测、计量检测等场所；解决了安防工程项目中之前很多难以解决的技术和施工难题；第二章技术参数品牌：VOANDOS 维安达斯型号ABJ-xxx-xF产品名称激光入侵探测器激光波长650nm或808nm警戒距离≤100米警戒层数单层或多层（可根据客户需求定制）报警源单光束/两光束同时遮断报警报警信号继电器开关量供电电压DC12V±10% 工作电流发射端：≥140mA （由光束数量决定）输出方式常闭,干触点外壳材质304不锈钢响应时间≥10mS 接收角度±30°发射光轴：X轴±30°Y轴±30°外形尺寸：100×100×330(mm)适应环境：-40℃～60℃防护等级：IP66第三章：产品工作示意图说明：需要进行发射机光束角度调整时，请先用螺丝刀拧开X/Y轴调整孔防水螺丝，然后用3mm一字螺丝刀伸入调整孔内进行调节第三章：安装调试1、根据需要防范的区域选好设备安装点；2、用自攻螺钉将反射板固定在和激光探测器的对面预定安装位置，反射板尽量保持垂直；将激光探测器在预定的安装位置上简单固定；连接好电源线和信号线（红色接DC 12V 正极，黑色接DC12V 负极，绿色、黄色为常闭信号输出，接报警主机或者其他控制设备）；3、由于反射式激光探测器采用的是808nm不可见激光作为探测器光源，为了提高调试效率，建议用户在傍晚或者晚上光线暗淡的时候进行调试，调试前请准备好一张A4大小白色纸板，小一字螺丝刀，十字螺丝刀，活动扳手等工具；4、对激光探测器通电（电源电压DC12V ),在探测器侧面可见探测器发射窗内有淡红色的激光；观察激光探测器蓝色的信号指示窗，如果信号指示窗内蓝色指示灯点亮，表示探测器接收窗没有收到反射回来的激光信号；5、拿一张A4大小的白色纸板以直立方式在探测器前方2米左右上下左右移动，纸板上是否有红色条状激光斑，当纸张上出现条状红色光斑，表示激光探测器发出的激光射线与纸板位置在一条直线上；测试者保持纸板直立，边往后退，边观察纸板上的光斑；在15米左右处，观察探测器---纸板----反射板是否在一条直线上，如果不是在一条直线上，请拔出探测器背面的X轴、Y轴调整螺丝孔的胶塞，用一字螺丝刀伸入调整孔内，调整X轴或者Y轴的调整螺丝，探测器的激光射线会随着手动调整，左右或者上下移动；边调整边观察，如果观察到激光射线与反射板在一条直线上，就暂停调整；6、测试者继续拿纸板往后退，保持激光射线光斑在纸板上可见，一直退到反射板附近，如果此时白纸板上的激光射线光斑位置与反射板位置明显不符，继续调整探测器X轴或Y轴的调整螺丝，直至激光射线光斑刚好投射在反射板上；只要激光射线投射到反射板上，激光射线就会被反射板反射回到激光探测器端，此时激光探测器上的蓝色指示灯就会熄灭，表示激光探测器已经收到反射回来的激光信号。

The Schleibinger Thin Layer Shrinkage Laser Measurement SystemSome building materials like self-levelingflooring compounds ore plasters areapplied in thin layers.These fast settingmortars set and harden within a couple ofhours and subsequent drying of such a thinlayer is generally terminated after the firstday. In order to investigate the dynamics ofearly shrinkage and expansion wedeveloped a special set-up of two laserunits which are horizontally aligned. Thisset-up allows to investigate the differentformulation parameters and theirinfluences onto the different stages ofshrinkage and expansion,namely theplastic shrinkage,setting expansion anddrying shrinkage.The shrinkage orexpansion behavior is strongly related toboth,external(climate)and internal(formulation) factors. With respect to the latter, begin, intensity and duration of setting are key to the overall shrinkage or expansion behavior.With building materials applied in thin layers shrinkage is one of the major issues because of two reasons: The high surface-volume ratio causes evaporation to be a dominant mechanism for strong and fast physical shrinkage, and the intense hydration reactions can cause a pronounced chemical shrinkage, or in case of ettringite formation a strong expansion.MethodTo investigate early shrinkage/expansionmechanisms in fast setting thin mortar layers aspecial set-up was developed which consists oftwo laser units. The two lasers are directedhorizontally onto a pair of light-weightreflectors, which are placed on top of the fresh mortar. The change in distance between the reflectors isµthen registered with an accuracy of 0.1 m. The non-contact laser device allows to start measurement right after emplacement of the fresh mortar.A data-logger supplied with the system records the data and store it in the logger as standard ASCII files. Optional a synchronous registration of temperature and humidity ore of a balance (Mettler) is possible. Two temperature channels and a mixed temperature /humidity channel are available. For measuring the vertical shrinkage the Laser sensors may be turned in the vertical direction. You may the measure directly on a mortar surface, or you may use the Schleibinger Shrinkage Cone vessel.The logger has a network interface (Ethernet). So you can easily integrate it into local intranet. With a standard web-browser software you can readout the data, and visualize it. For further data handling we recommend Microsoft Excel ® ore any similar visualisation program. The data are visualized online graphical and numerical on the screen. No special PC software is necessary. You need only your browser-software like Mozilla ore Internet-Explorer ® .An example measurementThe picture below shows astrong plastic shrinkage(shrinkage before setting) in thefirst hour. Close to the begin ofsetting,plastic shrinkage canturn suddenly into expansion.The current working hypothesisis that this is a pure structuraleffect related to a criticalconcentration of hydrates, whichcause the mineral grains(cement,sand and fine-grainedfillers) to become supported bya matrix of hydrates. From thismoment on any further hydrationcauses the mineral grains to be pushed apart (expansion). The ongoing chemical shrinkage (caused by continued hydration), which contributed to plastic shrinkage before, is now producing porosity. As the hydration rate decelerates, evaporation becomes the dominant mechanism and forces the mortar layer to shrink again. In most cases, this drying shrinkage levels out during the first day and the mortar layer becomes stable in volume .

lps国产激光测距传感器说明书(RS232)
激光测距传感使用手册前言尊敬的客户：衷心的感谢您选择了深圳市南方测控技术有限公司的激光测距传感器！为了让您更好的使用本激光测距传感器与防止意外事故的发生，请您在使用本激光测距传感器前仔细的阅读本说明书。
本说明书的版权归属深圳市南方测控技术有限公司所有，如在不影响本激光测距传感器整体性能的前提下所作的修改或更新，恕不另行通知。
激光测距传感器系统说明术语解释激光测距：利用激光对目标的距离进行准确测定。
激光测距一般采用两种方式来测量距离：脉冲法和相位法。
脉冲激光测距：基于激光脉冲反射时差法原理，测距仪器发射出的激光经被测量目标反射后，激光束被测距仪器接收，测距仪器记录激光往返的时间。
光速和往返时间的乘积的一半，就是测距仪器和被测量物体之间的距离。
激光测距传感器：为工业测量之产品，采用工业标准设计、生产和检测，可在线24小时连续实施测量，有的可以多台组网测试。
激光安全等级：国际上对激光有统一的分类，激光器分为四类（Class1、Class2、Class3 Class4）。
Class1激光器对人是安全的，Class2激光器对人有较轻的伤害，Class3以上的激光器对人有严重伤害，使用时需特别注意，避免对人眼直射。
Class2激光器：指激光器的出口光功率小于1mw，一般认为对人的眼睛是安全的，正常暴露在这种激光器的光束下不会对眼睛的视网膜造成永久性的伤害。
尽管此种激光器是安全的，但也不能长时间的直视激光光束。
如偶尔照射到人眼还不至于引起伤害，但连续观察激光束时能损伤眼睛。
此是对第二级激光器的最重要控制措施。
系统概述LPS系列激光测距传感器是一种功能强大的测量精确、无接触式的工业用距离测量设备，它可广泛地被集成用于各种工业用途的控制和监测系统上。
使用图例如下：目标LPS系列激光测距传感器是一款使用方便的工业应用激光测距仪表，特别为交通、炼钢、仓储、建筑、码头等需要自动进行距离和位置控制的应用而设计研发，具有很高地实用性。

Safety information and warningsSafetyThe system control unit contains hazardous voltages (110V AC or 230V AC mains depending on market). Disconnect or isolate from the mains supply before opening the door of the control unit. Power can be disconnected from the IEC plug on the underside of the control unit. The control unit must be earthed.The sensor head contains a visible laser diode of up to 35mW. The side of the sensor head has a warning label indicating the wavelength and intensity of the lasers in the sensor head.The system is a Class 3B device, according to EN60825: 1992. It is dangerous to look directly into the laser beam. Ensure that suitable precautions are taken so that direct viewing of the beam or viewing of reflections from mirror-like surfaces is not possible.The system is provided with fail-safe indicators on the sensor head and on the operator pendant. A keyswitch is also provided on the control unit to allow the laser to be disabled.The laser should be disabled before any maintenance is performed on the sensor head or welding torch when it may be possible to view the laser directly.The sensor head and control unit contain no user serviceable parts. No work should be undertaken on these items except by or under the direct guidance of appropriately trained personnel.To ensure safe and reliable operation of the system, all operators must be made aware of the correct operation and safety procedures for the system. The safety procedures should be based on the above information, installation specific issues concerning the use of the system and anylocal safety requirements.WarningsDo not weld with the sensor unless a spatter shield and a protective window have been fitted correctly.Please ensure that clean, dry, oil free air or gas is supplied to the air connectors on the top of the sensor body. Oil or water in the air supply will obscure the sensor view and stop it working correctly. It may also damage the sensor optics at the front of the sensor head. The welding shield gas or other bottled gas may be used, or alternatively air from a compressor can be used as long as it is clean, dry and oil free. A flow rate of approximately 5-8 litres per minute is normally required. When you place your hand underneath the sensor, you should feel a gentle breeze on the back of your hand. The flow should not be so high as to disturb the shield gas, while being sufficient to keep most of the smoke and spatter off the protective window.It is important that the sensor is provided with adequate cooling. The air supply above provides some cooling, but where this is not sufficient, additional cooling to the mounting plate for the sensor head can be used. This may be connected to a supply of cool water or to provide additional air cooling.The sensor head can also be cooled by providing chilled air from a Vortex type cooler unit. This cooled air can be supplied to both the air connector (at a flow rate of 5-8 litres per minute) and also to the ‘water cooled’ mounting plate by feeding the chilled air into either one of the ‘water connectors’ and allowing it to escape out of the other connector. The flow rate to the mounting plate should not exceed 12litres/minute.The user of the equipment must ensure that the cooling does not cause condensation to form on the windows or optics at the front of the sensor head, as this can stop the sensor from performing correctly. Although the sensor head is sealed against dust and being splashed by water, condensation must not be allowed to remain on the sensor head or pool around it for extended periods.You must turn the system off when replacing any parts, including the External GIO or the sensor head. If you do not do this, the system may fail to operate correctly.2. IntroductionThis manual describes the operation of Smart Laser Probe seam tracking system. The Smart Laser Probe system has been designed to be simple and reliable in normal operation. To get the best use from the system, please pay attention to the contents of this manual, particularly the sections ‘Safety Information’ and‘Maintenance’.For further details on the installation and configuration of the system, please refer to the Smart Laser Probe Installation and Support manual.For further information on the PC based set-up program, please refer to the Smart Laser Tools manual or alternatively use the help built into the Smart Laser Tools program.This manual refers to Smart Laser Probe software Version 1.0.3.

How the sensor worksThe sensor head contains an advanced camera, and a laser. The laser shines a red stripe onto the surface under the sensor. The camera views this stripe and from the shape of the stripe is able to see the shape (profile) of the seam. In front of the camera is a special filter that allows the light from the lasers to pass, but keeps out nearly all other light, such as the light from the welding arc.The sensor must be mounted in front of the welding torch in a position such that it can see the seam clearly. The distance from the sensor body to the workpiece should be correct for the type of sensor being used. When the welding torch is correctly positioned over the seam, the seam should be close to the middle of the laser stripe. This is so that the camera can clearly see the laser stripe and the seam within it. When the sensor is mounted correctly, the sensor picture of the seam will show the picture near the middle of the sensor view when the welding torch is at a good welding position.Sensor Head Laser stripe on the surface Camera viewThe sensor head is available with a range of different views depending on the application. The SLS V sensors are the standard range. The SLS H range are specially designed to be able to fit inside small diameter tubes and pipes (down to 6”/150mm ID).Table 1 Sensor heads field of view and standoff distanceSensor Head Field Of Viewmm Stand OffmmTypical ApplicationSLS 50 V 1 50 65Bigger seams up to 40mmSLS 25 V 1 25 45 Smaller seams up to 20mm SLS 50 H 1 50 65 Special format for inside pipeBigger seams up to 40mm SLS 25 H 1 25 45 Special format for inside pipeSmaller seams up to 20mm SLS 50 V 1 LR 50 150 Long range (higher standoff)version of 50mm sensorSLS 100 V 1 LR 100 150 Long range, large field of viewsensorThe Stand off distance is measured from the flat front part of the sensor head, where the end of the narrowing section, not from the spatter shield.Figure 5 Standard SLS Vertical sensor headFigure 6 SLS Horizontal sensor headFigure 7 - Principle of operationSensor pictureSensor pictureSensor pictureSensor HeadWorkpiece at normal standoffheightWork piece at smaller standoffrear of sensorWorkpiece at larger standoffThe picture from the camera is then processed by the electronics in the sensor head. It looks in the picture and decides where the stripe is in the picture. The software then uses the settings from the seam type to divide the stripe into lines that form the seam. From the position of the lines that make the seam, the system can then decide where the position of the seam is. This is then converted from a measurement in the picture into a measurement in mm of the seam position under the sensor. This conversion is performed using the ‘calibration data’ that is stored in each sensor head.When the system is tracking, it uses the welding speed and the distance between the sensor and the welding torch to calculate a delay time. It compensates for this delay time when using the measurements of the seam position to drive the slides to keep the welding torch positioned over the seam.5. OperationThis section describes the operation of the Laser Probe. For details of how to install and set-up the Laser Probe system, please refer to the Laser Probe Installation and Support manual.The Laser Probe system is operated from the Operator Pendant, and also by the switches on the Control Unit.5.1. Control Unit SwitchesThe control unit has the following switches.•Power on/off switch•Laser Enable keyswitch•Mode keyswitch5.1.1. On/Off SwitchTurning the power switch on the front of the control unit clockwise turns on the system. When power is on the touch screen display (GIO) will start to turn on. The system performs a range of self tests, and if it doesn't find any problems will turn on the LED in the start button on the operator pendant to show that the system is ready to be started. If the system does detect a problem it will turn on the red status LED. You can then use the display on the GIO or the Smart Laser Tools program to determine the cause of the error. Note that the GIO may take longer than the rest of the system to power on - the rest of the system can be used as soon as the green pendant start button illuminates, even if the GIO is still starting up.Turn the power switch anti-clockwise to turn off the system. Note that all settings that have been entered are stored in the Smart Laser Probe system, so the power can be turned off and on without the need to set-up the system again. When not in use the equipment can be left turned on or turned off as convenient.5.1.2. Laser Enable KeyswitchFor safety reasons, it is possible to disable the lasers in the sensor head. This is done by turning the Laser Enable keyswitch to the anticlockwise (OFF) position. The key can only be removed in the OFF position. To operate the system it is necessary to place the key in the switch and turn it to its clockwise (ON) position. It is necessary for the lasers to be enabled before it is possible to make any measurements with the system. If you try to use the system with the lasers disabled, an error message will be displayed on the GIO and the red status LED on the Operator Pendant will illuminate.When performing maintenance on the sensor head or welding torch, or when untrained personnel are working by the sensor head, the Laser Enable key must be turned to the OFF position. The Laser Enable keyswitch must also be turned to the OFF position if the sensor head is to be moved to a position where it is possible to look directly into the end of the sensor.Please refer to the safety regulations in force in your area for appropriate safety information.5.1.3. Mode Switch KeyswitchThe mode switch controls the operating mode for the equipment. It is a two-position keyswitch, and in normal use it should be in its anticlockwise position, RUN. The key can be removed when it is in the RUN position to ensure that the system set-up cannot be modified.Certain aspects of the set-up that has been made for your system can be adjusted from the menus that are displayed when this keyswitch is turned to the SETUP position. Please only attempt this if you are familiar with the set-up of the Smart Laser Probe system and are authorised to do so. To control access to these modes, it is possible to remove the key when in the RUN position.5.2. Operator Pendant - DescriptionThe Operator Pendant is used to operate the Smart Laser Probe system.The Operator Pendant has the following LED lamps and controls.•Four bicolour illuminated JOG buttons (left, right, up and down)•Illuminated START button•Illuminated STOP button•LASER button and laser warning lamp•Illuminated bicolour STATUS button•Illuminated SEAM button•Illuminated OFFSET buttonSome operator functions described below can be turned off when the system is installed if they are not required. This is done during the installation of the system, and it is noted in the description below. Some operations such as starting the sensor searching and tracking, and seam number selection can be performed by a connection to a PLC. These are also described below, but for details of how this is set-up, please refer to the Smart Laser Probe installation manual.The boxes in the following description show what you will see on the display on the Operator Pendant.5.3. Operator Pendant - in Standby – OperationsThis section describes the operations that you can perform on the Operator Pendant, when the sensor is not searching or tracking a seam. This mode is called Standby.5.3.1. Jogging the slidesThe 4 JOG buttons can be used to jog the slides. When jogging the slides, the slide will move slowly at first, gradually getting faster over a few seconds until the maximum jog speed is reached. This allows fine control of the jog position to be achieved while still being able to jog larger distances at a higher speed. The green LEDs in the joy switches are lit when it is possible to jog the slides. Note that if the system is under automatic control, e.g. searching for or tracking along the seam, the greed LEDs in the jog switches will turn off, to show that you are not able to jog the slides.The slides will stop when they reach the limit switch, and will not move any more in the direction of that limit switch. Note that when in Standby and jogging, reaching a limit switch does not cause an error to be reported. However, when a limit switch is active the red LED in the jog switches is illuminated, and the end of the slide icon on the GIO turns red to indicate which limit is active.Selecting the seam numberIf necessary, the Smart Laser Probe system can be set up to search for and track several different seams. The different settings that the system needs for the different seams are stored as separate seam numbers.Different seam numbers can be selected by holding down the SEAM button, and using the JOG up to increase the seam number or JOG down to decrease the seam number. The green led in the jog up or down button will flash briefly if the seam number changed. Seam numbers always start from 1. Only seam numbers where the seam have been created will be selected - any seam number that has not been created will be skipped. It is also possible to select the seam number from the GIO, from the 'seam' tab.It is possible to disable changing seam number from the pendant. It is also possible to select the seam number from a PLC via digital signals. Whichever way it is selected, the active seam number is shown on the GIO display.5.3.2. Turning the sensor lasers (measurement) on and offPressing the LASER button will turn the lasers on. When the lasers are on, the Smart Laser Probe system will continuously attempt to measure the position of the seam, relative to the middle of the field of view of the sensor. Pressing the LASER button again will turn the lasers off. You can also turn the lasers and measurements on and off from the GIO. When the laser is on, the STATUS LED will turn green when the sensor is able to measure the position of the seam, and turns off if the seam is not visible.5.3.3. Automatically adjusting the picture brightnessThe SLS sensor head will normally automatically adjust the picture brightness depending on the current surface below the sensor. Adjustment of the picture brightness is not normally required.5.3.4. Teaching the sensor zero positionPressing the SEAM then LASER buttons together will ‘teach’ the correct tracking position for the seam. This will normally be done when the system is installed, and will need to be redone if the sensor or welding torch position changes. Section 5.7 has more details if this happens.Teaching the seam tells the sensor that the current position of the seam under the sensor is the correct position for the seam. When the seam is taught, the sensor will measure the position of the seam underneath it and store this position as the correct (zero) position for the seam. When the sensor sees the seam in this position, it does not need to make any corrections. The system will briefly flash the blue SEAM LED if the teach was successful. If the seam position can't be determined by the sensor, it will turn the STATUS LED red.The ability to ‘teach’ the sensor from the Operator Pendant can be turned off during installation, if it is not required.5.3.5. Starting the sensorWhen the system is ready to be started, the green START LED will be illuminated. If the green start LED is not glowing, then either the system in already started (in which case the green STOP LED will be illuminated), the system may be in error (in which case the STATUS LED will be red), the Smart Tools program may be active or the system is not running (for example, the sensor head is not connected (which will be displayed on the GIO unit). Pressing the START button will start the sensor searching for the seam. See section 5.6, Typical operating sequence, for further details. Pressing the STOP button will stop the sensor, returning it to Standby mode. When the system is started, the green START LED will turn off and the green STOP LED will illuminate to show that you can now press the stop button to stop the system.The START and STOP functions can be controlled from a PLC. The function of these buttons can also be turned off during the installation if start and stop is only to be possible from the PLC.5.3.6. Error acknowledgeIf an error occurs and the red STATUS LED turns on, the cause of the error will be displayed on the GIO. Press the STATUS button to acknowledge the error before continuing to operate the system. Note that the error acknowledgement can also be performed from a PLC if one is connected to the system.When the error is acknowledged, any movements that may have been configured with the extended movement function will be executed. Typically, this function would be used to retract the slides from the workpiece, or to move the slides to a known position.5.4. Operator Pendant - Sensor ActiveThis section describes the use of the Operator Pendant with the sensor searching for or tracking along a seam. The sequence of events listed below starts when the START button is pressed, or, if the Laser Probe system is controlled from a PLC, when the PLC sends the start signal to the sensor.5.4.1. Extended move (configurable option)The extended move function allows a pre-programmed sequence of slide movements to be made before the sensor is activated. This could be used to pre-position the slides. The GIO display will show that an extended move is active, and which move in its sequences it is currently making.5.4.2. Vertical search (configurable option)The vertical search function allows the sensor to search downwards until the sensor can see the part beneath it. It would be used when the part can initially be too far away to be within the view of the sensor. As it drives the slides down, the GIO will display ‘vertical search’. When the part appears in the sensor view near the taught height, it will switch to the normal or (if enabled) the extended search mode.If the sensor still cannot see the laser stripe when it has moved a certain distance, which is called ‘max vertical search distance’ and is specified in the Smart Tools program, vertical search will stop and an error message will be displayed.5.4.3. SearchingWhen searching, the GIO display shows the mode and also the side (Y) and height (Z) correction that it has made in moving to the correct starting position (excluding extended move and vertical search movements).In tracking mode, the GIO display shows the error in the seam position under the sensor head. The green JOG LEDs also flash to indicate the direction that the sensor is correcting in.The GIO display also shows the percentage of pictures over the last second that the sensor was able to make a measurement on. This number should be around 80-100% except when the sensor goes over tacks or other damaged parts of seam when it can drop to zero.In tracking mode, if you press the SEAM button and use the jog up or down buttons you can increase or decrease the active seam number. Changing the seam number while tracking can be useful if the shape of the seam changes as you go along it or if you need to adjust the welding position or measurement settings.During tracking, it is possible for the tracking to be paused for a short time, for example if the welding stops with on a welding fault. If the sensor is given the‘pause’ signal when this happens, the GIO display will change to indicate this.If the system is being controlled by external signals, for example from a PLC, then a further mode is possible. This is called ‘locate’ and is used if the position of the seam under the sensor at the start of the seam can vary by more than the view of the sensor. In this mode, the sensor is scanned over the part until the sensor can see the seam. When this happens, the sensor will turn on the ‘seam’ LED briefly.5.5. Operator Pendant - RUN mode with Sensor Active - Operations5.5.1. OffsetThe JOG switches can be used to offset the position that the sensor is tracking on the seam. This can be used to make small adjustments to the welding position while the system is tracking, without having to stop and re-teach the sensor. You can adjust the side position with the left and right JOG switch, and the welding stick out with the up and down JOG switch. The offset will be in the direction of the Jog switch pressed, relative to the sensor body when looking in the welding direction. Note that if the sensor is not mounted aligned with the slides or if the jog direction has been adjusted, this may not be the same as the jog directions.The offset is added each time you push the jog switch. The switch does not auto repeat when you hold it on. The amount of offset for each push on the switch depends on the view of the sensor being used. The offsets used are shown.Table 2 - Offsets per jog key pressSensor Head Offset per pressSLS 50 V1 0.2 mmSLS 25 V1 0.1 mmSLS 50 H1 0.2 mmSLS 25 H1 0.1 mmThe total amount by which you can offset is limited by the Smart Laser Probe system to an amount depending on the field of view of the sensor. This limit is +/-25% of the sensor view to the side, and +/-50% in height. This is because if you make too much offset, then it would be possible offset the sensor so much that the seam was no longer within the view of the sensor. When you reach this limit, the system will not offset any further in that direction.This ability to offset the seam position can also be turned off during the installation if it is not required.5.5.2. StoppingThe STOP button will stop the tracking. The lasers will be turned off. If the extended move function is enabled, sequence of extended movement will be implemented to move the sensor away from the seam. After that, the slides will be deactivated and the Laser Probe will return to STANDBY mode.The START and STOP functions can be controlled from a PLC. These Operator Pendant buttons can also be turned off during the installation if they are not required. The other buttons on the Operator Pendant have no effect.5.6. Typical operating sequenceThis section describes the typical sequence when the sensor is used in the welding of a seam. It assumes that the sensor can be positioned over the seam before the sensor is activated, and that the sensor starts the welding automatically.The first step is for the sensor to be positioned approximately over the seam. If necessary, this would be done by jogging the slides from the operator pendant.The sensor will then be given a signal to search for the seam. This may come from the operator pendant or from a signal from a PLC.If the lasers are not already turned on, the sensor will turn on the lasers. It will then take a picture and measure the position of the seam. If it can see the seam, it will drive the slides to move the sensor to its ‘teach’ position over the seam. The sensor will then take another picture, measure the position of the seam and move the slides. This will be repeated until the sensor is correctly positioned over the seam.The Laser Probe system then turns on the SEAM LED, and switches to tracking (seam following) mode. The system is now ready to start welding. The sensor also sets an output signal that can be used to start the welding automatically.In tracking mode the sensor measures the position of the seam underneath it, and then smoothly adjusts the slide position to keep the welding torch correctly on the seam. If the part is twisted a little off position, the Laser Probe system will move the slides to correct for this, allowing for the time delay between the welding torch and the sensor head. The system will only correct smoothly, averaging the path over the look-ahead distance to generate a smooth movement. It therefore follows the overall direction of the part rather than every small irregularity in it.The Smart Laser Probe system will continue to work even if it cannot see the seam underneath it, for example when it goes over a tack. This can occur for a distance of up to the ‘tack length’, which will have been set when the system was installed. While the sensor cannot see the position of the seam, it will keep the slides moving as they were before the tack - it keeps going straight in the same direction as the seam before the tack. If the seam is not visible for longer than the tack length, then it will stop with the error ‘seam not visible’.。
