3 Safety notes and usage in accordance with intended purpose 3.1 General safety notes SIEMENS products are developed and manufactured with careful application of standard rules of the industry. The protective function of the devices can be negatively affected, however, if they are used improperly or not in accordance with their intended purposes.
3.3 18 • The 24-V DC power supply must be fed to the scanner through a separate branch with a 1.25 Amp delayed action fuse in the control cabinet. • Guard operation is only permitted with the control cable (X1) of the dummy connector . This also applies for transport and storage. • The safety output has a double design.
• Make sure that the following types of light sources are not present on the scanning plane: - Laser light from one or more other scanners or sensors - Infrared light - Fluorescent light - Stroboscopic light Please consider as well Chapter 5.2. 3.4 • It must not be used with internal combustion engines. • The SIMATIC FS600 Laser Scanner is conceived for use inside enclosed spaces and with the operating parameters listed in the technical specifications (temperature, humidity, shock, vibration, etc.).
3.5 General information related to determining detection zone contours • Shadow effects (e.g. surfaces or areas located behind stationary objects) must be considered. As a rule, insufficient safeguarding must be adequately supplemented by further safety measures such as guard fences, light curtains, and the like! • Access to the detection zone in the dangerous area is not permitted. • When setting the dimensions of the detection zone, you must comply with the formulas cited in Chapters 5.4.8 and 5.7.
3.6 • When calculating the safety distances, be sure to consider all delay times, such as the response time of the scanner, response time of the control elements, and braking times and/or stopping times of the machine/system or AGV! Variations in delay time caused by factors such as reduced braking power must also be taken into consideration.
3.7 22 Additional Safety Notes for Mobile Use • There are additional requirements for the use of scanners on automatic guided vehicles (AGV) and transporter trolleys according to DIN EN 1525. • If possible, expanded detection zones to each side should be provided in order to safeguard access from the side and directly in front of the vehicle.
4 Applications for the SIMATIC FS600 Laser Scanner Due to its continuous coverage of the area, its wide range, and the ability to select among four / eight zone pairs, the SIMATIC FS600 Laser Scanner is able to handle even complex applications 4.1 Stationary Safeguarding of the Danger Area The SIMATIC FS600 Laser Scanner is used to safeguard dangerous working areas at machines and systems where both constant and variable demands are placed on the geometrical shape of the detection zone.
4.2 Access guarding by passage monitoring Access guarding by passage monitoring (whole body trip control) is a suitable method when the access to a machine or to a hazardous zone can be precisely defined in structural terms, and there is no other unprotected access to the area. It is best to mount the laser scanner above the passage in question, in vertical alignment.
4.3 Safeguarding of danger points based on hand and arm detection If the machine operator, in close proximity to the danger zone, needs to halt the hazardous movement of the machine or to coordinate the handling of workpieces or their removal from the machine, the machine must be provided with protection at the danger point. To safeguard danger points in this way a protective system needs to be installed.
4.4 Mobile Safeguarding of Automatic Guided Vehicles For this application, the SIMATIC FS600 Laser Scanner is installed on automatic guided vehicles in order to monitor the vehicle path. The aim is to detect people or objects in the path of the vehicle and to automatically bring the vehicle to a halt. Safety systems available up to now, such as bumpers or safety bars, have allowed only very low driving speeds to be maintained.
SF1 SF2 SF1= Detection zone 1 for slow speed Fig. 4.5-1: SF2= Detection zone 2 for high speed Safeguarding a transporter trolley Please comply with the safety notes in Chapter 3 and Chapter 5.7.8. In these cases, the SIMATIC FS600 Laser Scanner is used to detect people or objects in the vehicle path and then automatically bring the vehicle to a halt. Select “Manual restart” mode.
Fig. 4.6-1: Bild 6.3-1 Guarding the sides on AGVs Please observe the safety notes in Chapter 3. An example for the side guarding configuration on AGVs can be found inChapter 5.7.9 and 5.7.10. 4.7 28 Other possible applications • Object and contour measurement • Logistics (counting, measuring, controlling) • Projection control (e.g.
5 Information for Planning and Mounting It is essential that the following key points be complied with so that the SIMATIC FS600 Laser Scanner can provide optimum performance: • The SIMATIC FS600 Laser Scanner must be placed so that areas of access to the danger zone being monitored are completely covered by the detection zone. • The mounting position of the scanner should provide protection from humidity, dirt and extreme temperatures below 0° C or over 50° C.
5.1 Attachment and Dimensions For attaching the SIMATIC FS600 Laser Scanner, four drill holes are located at the back of the unit. Any laser scanner installation point is possible with mounting. The SIMATIC FS600 Laser Scanner can, for example, also be mounted on the head or inclined facing down. The mounting set 3RG7838-1AA is available as an accessory offering following advantages: • Speeds up the mounting process by providing screws that are accessible from the front.

In addition, the contours can be infinitely varied by: • changing • limiting and • deleting partial segments as desired 5.3.2 Range of the Detection Zone, Resolution The maximum range of the detection zone SMAX 4 m (including the additions) for an object with a diameter of 70 mm and a reflectance factor of 1.8 % (e.g. black corduroy). The reference point of the measurement is the axis of the rotating mirror on the scanner 64 mm behind the front edge of the scanner. 5.3.
5.3.4 Range of the measurement field The maximum distance for contour measurement at a reflectance factor of 80% (white gipsum) is 50 m. Remission in % Reflectors White gypsum Writing paper Gray carton b a Black corduroy 15 Distance in m a = Detection zone b = Measurement field Fig. 5.3-2: 5.3.5 Detection of objects depending on the reflectance factor. The reference point of the distance measurement is the axis of the rotating mirror.
If retro-reflectors or very shiny surfaces, such as polished or enameled metals or ceramics, may possibly be present in the scanning plane, the following table applies: Addition ZREFL if retroreflectors or very shiny, surface-treated materials (e.g. metals and ceramics) are present in the scanning plane 0 mm for reflectors more than 1.2 m behind the detection zone line 110 mm for reflectors up to 1.
5.4.3 Mounting Height According to DIN EN 999, the lowest admissible height of the scanning plane for people, as measured from the base level, is calculated according to the following formula: HMIN = 15 * (d - 50 mm) HMIN d = Lowest admissible scanning plane from the base level = Resolution of the scanner in mm (object size = 70 mm throughout the detection zone).
5.4.4.1 Recessed installation (undercut) under the machine table The undercut must be at least as deep as the zone not monitored by the detection zone lateral to and in front of the scanner. The minimum depth ZUMIN is 135 mm. If it is possible to recess the scanner, this is allowed up to a maximum of 40 mm; the depth of the undercut is reduced by the depth value of the recess. If the mounting system is being used, the necessary dimensions of the undercut depth must be increased accordingly (see Chapter 14.
5.4.4.2 Recessed installation within the machine contour Furthermore, the scanner can be recessed into the contours of a machine. The recess can have a depth of up to 40 mm without the mounting system 3RG7838-1AA, or up to 65 mm with the mounting system 3RG7838-1AA. This is in reference to detection zones that cover an angle range of 180°. If it is not possible to comply with these values, or if unmonitored zones result due to the shape or movement of the machine, additional safety measures must be taken.

ZUMIN c d b Z Fig. 5.
5.4.5 Additions The axis of the rotating mirror (midpoint of the scanner) is of critical importance when configuring the detection zones. This axis is assigned a value of 64 mm from the front edge of the scanner when calculating detection zones. Add 83 mm or 100 mm for the maximum radial measurement error ZSM as described in Chapter 5.3.5 . Add an addition ZREFL as described in Chapter 5.3.5 if reflectors could be present in the area.
SAFETY NOTES Automatic startup / restart must only be used in cases where there is absolutely no possibility that the effective detection zone could be entered or bypassed in some other way. Depending on the hazard assessment, visual and / or acoustic startup warnings should be provided. If parameters are set for the function “Manual restart”, the required enable from the startup/restart button affects all detection zones and is independent of any detection zone changeover.
5.4.8 Calculating the Detection Zone Dimensions for Safeguarding an Area According to IEC 61496-3 and DIN EN 999, the following formulas apply for calculating the safety distance and the minimum depth of the detection zone when the direction of approach runs parallel to the detection zone: S C S K T C CMIN H HMIN HMAX d 42 = = (K x T) + C 1200 mm – 0.
5.4.8.1 Additions and Minimum Depth of Detection Zone The sum of the system-specific and application-specific detection zone additions (see Chapter 5.3.

5.4.8.3 Sample calculation of the depth of a detection zone This example is based on the following application data (see 5.4-5): Largest width between the axis of the rotating mirror and the boundary of the danger zone GBDIFF 700 mm Access speed K 1600 mm/s (constant) Response time of the SIMATIC FS600 Laser Scanner (adjustable) TSCAN 0.08 s Response time of the machine or system TMACH 0.1 s Stopping time or lag time of the machine or system TLAG 0.
5.4.8.4 Sample calculation of a maximum range of a detection zone The formulas: 222222 2 22 = S T + S BDIFF S MAX SBDIFF = GBDIFF + S + ZSM yield, under consideration of the width of the danger zone results in the maximum distance to be monitored: 2 2 S MAX = 2456mm + 3031mm SBDIFF = 700 mm + 2248 mm + 83 mm = 3031 mm SMAX = 3901 mm 5.4.8.5 Sample calculation of an undercut This example is based on the following application data. If the scanner is mounted across from the machine (see Fig. 5.
5.5 Access protection Please have regard to the General Notes on Safety in Chapter 3. 5.5.1 Object of protection The object of protection is the safeguarding • of individuals when they access a danger zone. The SIMATIC FS660I Laser Scanner will detect the passage of individuals and the intrusion of an entire human body into the scanning field of the laser scanner. 5.5.2 Installation position Access protection is based on passage monitoring.
The safety distance for an access protection system may be calculated, based on EN 999, by means of the following formula: S = KxT+C S = Safety distance in mm K = Approach velocity in mm/s T = Overall time of delay in seconds, a total consisting of: C = here = 1600 mm/s Response time of the laser scanner here = 80 ms Overtravel time of the machine including the controls Based on measurement of overtravel time Added margin on account of the possibility of manual intrusion here = 850 mm Ple
The reference boundary must cover at least two sides of the detection zone. The detection zone itself must be defined in such a way that no gaps can arise through which a person could pass through the passage without being detected. The reference boundary is defined with reference to the non-moving parts of the passage. These will then be constantly monitored by the laser scanner, so that any individuals intruding or other manipulative intervention will be detected beyond the possibility of doubt.
To safeguard the danger point, a safety distance S must be observed between the detection zone of the laser scanner and the danger zone. The SIMATIC FS660I Laser Scanner can fulfil its protective function only if it has been installed and positioned in such a way as to allow for an adequate safety distance. The safety distance ensures that no body part whatever can reach the danger point until the hazardous movement of the machine has come to a complete standstill.

Fig. 5.
5.7 Safeguarding Mobile Machines Please comply with the safety notes in Chapter 3. 5.7.1 The Purpose of Safeguarding is for protection: 5.7.2 • to protect people when entering variable danger zones • to protect objects located in the vehicle path • to protect the automatic guided vehicle and its load Installing adjacent laser scanners The SIMATIC FS600 Laser Scanner has been developed in a way that prevents several laser scanners from interfering with one other as much as possible.

5.7.6 Additions The axis of the rotating mirror (midpoint of the scanner) is of critical importance when configuring the detection zones. This axis is assigned a value of 64 mm from the front edge of the scanner when calculating detection zones. Add 83 mm or 100 mm for the maximum radial measurement error ZSM as described in Chapter 5.3.5 . Add an addition ZREFL as described in Chapter 5.3.5 if reflectors could be present in the area.
5.7.7 System Availability There must be a buffer distance of 83 mm between the surrounding contour and the detection zone contour (including the additions). This distance increases the up-time of the AGV, since it prevents the surrounding contour from being detected as relevant for generating a switch-off signal due to a measurement error. Furthermore, the dust algorithm of the SIMATIC FS600 Laser Scanner can be implemented if floating particles may be present in the area.
5.7.9 Calculating the Dimensions of the Detection Zone of an AGV Application Following are the specifications and calculation examples for the mobile safeguarding of automatic guided vehicles.. According to IEC 61496-3, the following formulas apply for calculating the safety distance: S = (VMAX x T) + SSTOP VMAXAGV= Maximum speed of the AGV, in mm/s T = Response time of the scanner and the AGV, in s SSTOP = Braking distance of the AGV until standstill, in mm 5.7.9.

5.7.9.3 Sample calculation of the depth of a detection zone This example is based on the following typical application data (without access against the direction of travel and without retro-reflectors): Largest width of the danger zone from the axis of the rotating mirror = GBDIFF 1400 mm Maximum speed = VMAXAGV 1800 mm/s Response time SIMATIC FS600 Laser Scanner (selectable) = TSCAN Response time of AGV control = TAGV 0.1 s Braking distance = SSTOP 1900 mm 0.
5.7.10 Side guarding configuration on AGVs All previous considerations and the Chapter 5.7.9 calculation for calculating the detection zone measurements of an AGV application also apply for side guarding on AGVs. With AGVs that drive along conveyor segments it should always be ensured that big enough undercut is provided (see also, details in Chapter 5.4.4).
6 Details on switching over detection and warning zones During the course of an optimum machine utilization an alternate infeed or machining cycle often occurs, which brings the most diverse danger areas with it. Automated guided vehicle system applications by their very nature include various danger areas, depending on the operating status. If the approach or presence of people is now to be expected in these areas, the need exists of a precisely adjusting safety system.
Table 6.1-1 applies with activation (start or switchover) of zone pairs 1 to 4. Zone pair Control input FP1-FP2-FP3-FP4 1 1 - 0 - 0 - 0 Zone pair 1 is active 2 0 - 1 - 0 - 0 Zone pair 2 is active 3 0 - 0 - 1 - 0 Zone pair 3 is active 4 0 - 0 - 0 - 1 Zone pair 4 is active Table 6.
The following points also apply for the switchover: • The switchover must be made within 40 ms, i.e. after 40 ms one of the input connections shown in Table 6.1-2 must be valid and provided stable. During the switchover time the old zone pair is monitored; the new one after max. 80 ms. • The switchover process executed by the control unit must concur with the laser scanner's configuration, which was set beforehand with SIMATIC FS600 Parameterization Software LS4soft.

7 Functions of the SIMATIC FS600 Laser Scanner The SIMATIC FS600 Laser Scanner is equipped with the X1 and X2 interfaces. The following functions are available through them: 7.
7.3 Alarm 1 (X1-5) As long as the output X1-5 is switched on, the system signals trouble-free operation. If it is switched off, the following states are reported: • Interruption of the warning zone is shown by the continuously lit LED 2 in the indicator field of the scanner. • Warning state: For instance, the system may detect a slight dirt buildup on the optical window. To signal this state, LED 5 on the scanner flashes (2 Hz).
7.5 OSSD 1 (X1-12) and OSSD 2 (X1-11) When the detection zone is interrupted, the two semiconductor outputs switch off and, by way of elements such as positively guided relays, cause the monitored machine(s) to shut down. It is not admissible to control different safety circuits with a single OSSD. Connected loads must exhibit a low-pass behavior in accordance with the plausibility control conducted by the scanner (fg ≤ 1 kHz, CL ≤ 100 nF).
8.1 Integrating the SIMATIC FS600 Laser Scanner with External Wiring with Relays and Quadruple Zone Pair Changeover In this connection example, the restart interlock function is provided by the connected command unit “WA”, which applies the voltage of 24 V to the input RESTART X1-2. The SIMATIC FS600 Laser Scanner itself must be configured using the “SIMATIC FS600 Parameterization Software LS4soft” user software so that the operating mode “with restart interlock” is active.

9 Electrical connection 9.1 Electrical Power Supply The SIMATIC FS600 Laser Scanner requires a direct voltage of 24 V and 8 W of power plus the load at the outputs (max. 25 W). The power must be supplied by way of an external 1.25 A, semi time-lag fuse (e.g. in an electronics cabinet). In addition, a permanent current of 2.5 A must be ensured before safeguarding begins in order to guarantee that the fuse will be triggered in case of a fault.
The connector adapter of control cable X1 must be connected with interface X1 and screwed tightly to the SIMATIC FS600 Laser Scanner. The connector adapter of cable X2, or else the X2 dummy cap (without a cable), must also be screwed tightly to the SIMATIC FS600 Laser Scanner. Threaded drill holes are located on the top of the scanner housing for this purpose. If one of the two connection housings is missing, the SIMATIC FS600 Laser Scanner no longer meets the requirements of protection type 65.

11.7 Replacing the Optical Window 11.7.1 General information: • Only professionally trained personnel are permitted to replace optical windows. • Be careful everything stays clean during all jobs. (If possible, work in a dust-free environment. A production hall is not a good place for working on the device). 1) Loosening the housing parts Loosen the four Allen screws on the rear housing wall. Take the two housing parts carefully apart from each other and place them on a level surface.
3) Checking the condition of the scanner Please do not fail to observe: Check the mirror, optics and housing parts to make certain they are free of dust. Dry if necessary with a dry, oil-free, light jet of compressed air with appropriate components. Do not touch any parts in the device.
5) Assembling the housing When assembling the housing, note that the two retaining bolts slide into the rubber sleeves provided for them. To do this, carefully join the two housing parts on a level surface. Retaining bolts Rubber sleeves After that, carefully screw in the screws on the rear wall of the housing, working back and forth around the circle from screw to screw. Remove any finger prints on the optical window 11.7.

11.8 Cleaning 11.8.1 Cleaning the Optical Window when Dirty Different methods will work better under different conditions depending on load and medium. What is the best approach? Note: Clean sets 3RG7838-1AA are available for cleaning the optical window. They contain a special cleaning agent and suitable cleaning cloths. Two sizes are available. For more information, see the chapter entitled “Accessories and Spare Parts”.
11.8.2 Cleaning the Optical Window; Cleaning Diffusing Light Panes The front and light panes and diffusion screens must be washed depending on the load on the application in question. Generally this is a quick process. Fig. 11.8-1: Cleaning the Optical Window Sharp cleaning materials and / cloths that scratch must never be used! Fig. 11.8-2: Cleaning Diffusing Light Panes Note: Dirt can often be eliminated in a work step. If the optical window is cleaned within 4, the scanner is not turned off.
