The mounting system is available as an accessory. 3.
Functions 4 Functions The functions must be coordinated with the respective application. You configure the functions with the help of the LS4soft configuration and diagnostics software. 4.1 Start/restart interlock The start/restart interlock has two functions: • Start interlock • Restart interlock Using start/restart interlock ª In addition to the Safety Sensor you must also install the start/restart button. The machine operator starts the machine with this start/restart button.
Functions 4.2 Start test The start test function compels the operator to interrupt the protective field once after the Safety Sensor start, e.g. with a test rod. Only then can the machine be started. Using the start test If you combine the start test with the automatic restart function, the start test serves as an automatic start/restart signal. 4.
Functions Field pair switchover The Safety Sensor has four or eight field pairs. Switchover between the field pairs is possible at all times, provided the operating situation allows this. During the switchover process the Safety Sensor monitors the field pair activated before the switchover until a new one has been clearly activated. Use the field pair switchover when the danger zones vary depending on the activity of the machine or the operating status, e.g.
Functions Table 4.1: Connection of control inputs FP1 to FP4 with activation of field pairs 1 to 4. Field pair Description Control input FP1 FP2 FP3 FP4 1 1 0 0 0 Field pair 1 is active 2 0 1 0 0 Field pair 2 is active 3 0 0 1 0 Field pair 3 is active 4 0 0 0 1 Field pair 4 is active The following rules apply for switching over eight field pairs: • The switchover must be made within 40 ms, i.e. after 40 ms an input connection must be valid and stable.
Functions WARNING Field pair switchover to field pair 8 deactivates the monitoring function No field pair is no monitored; the safety outputs (OSSDs) remain constantly active. ª Never start the Safety Sensor with field pair 8. ª Only use field pair 8 when there is no danger for people present, e.g. with vehicles in creep and reverse, in the area of loading or park positions or during machine cycles with which there is no danger for the operating staff.
Functions 4.7 MotionMonitoring The MotionMonitoring function supports you with the configuration of the Safety Sensor for the mobile danger zone guarding application, and during the operation, monitors whether or not the control system has selected the correct, situationappropriate protective field. The Safety Sensor calculates the current speed from the measured values and compares this with the speed that is given in the speed matrix for the protective field.
Functions Using MotionMonitoring Requirements for using the MotionMonitoring function: • Transfer trolley (AGV) with linear movement • Driveway length max. 50 m • Driveway restricted at both ends by a wall or boundary ª Enter the speed levels of the AGV and the braking distance with maximum speed in the speed matrix with the configuration. The software interpolates the missing braking distances and automatically defines the protective and warning fields.
Applications 5 Applications The following chapters essentially describe the Safety Sensor's usage possibilities. To safely configure and mount the Safety Sensor for the respective application, see Chapter 6. 5.1 Stationary danger zone guarding Stationary danger zone guarding enables a very spacious protection of people on machines that are to remain as accessible as much as possible. The Safety Sensor is applied as a stop-activating and presence-detecting protective device.
Applications Stationary point of operation guarding Hand and arm protection are always required when people must work at the point of operation. The Safety Sensor is applied as a stop-activating and presencedetecting protective device. The Safety Sensor's protective field is set up vertically in front of the machine or system's point of operation. With small protective field dimensions the Safety Sensor provides the correspondingly required high resolution level.
Applications 5.3 Stationary access guarding Stationary access guarding protects people that step into a danger zone. The vertically aligned protective field of the Safety Sensor detects the passage of a person. A side post and the floor serve as reference contour for monitoring the position of the protective field. In contrast to danger zone guarding, the Safety Sensor no longer registers a person in the danger zone after the passage.
Applications Mobile danger zone guarding Mobile danger zone guarding protects people that are located in the driveway of an automated guided vehicle. The distance between the protective field front edge and the vehicle front must be greater than the stopping distance of the vehicle with selected speed and maximum load. A safe control system selects speeddependent protective fields and can activate side horizontal protective fields for curved stretches. 3 4 3 1 4 TNT 35/7-24V 5.4 2 3 Pic. 5.
Applications 5.5 Mobile side guarding Mobile side guarding protects people and objects that are located on the vehicles path. This application is used when very low arranged conveyor lanes do not permit an unobstructed passage of horizontal, lateral overlaying protective fields. The Safety Sensors are positioned laterally and the protective fields are arranged vertically, at a slight tilt.
Installation 6 Installation 6.1 Basic infos The Safety Sensor's protective function is only guaranteed when the device arrangement, configuration, protective field dimensioning and installation are coordinated with the respective application. The installation work must only be performed by an appropriately qualified person in compliance with the applicable standards and these instructions. The installation must be thoroughly inspected on completion.
Installation ª Determine the conditions for the field pair switchover, if required. ª Configure the Safety Sensor with the configuration and diagnostics software. Many safety-relevant parameters are preset in the configuration and diagnostics software. Use these preset values where possible. ª Create a record document for the device configuration and protective field dimensioning. The document must be signed by the person responsible for the configuration.
Installation ª Do not use cone-shaped protective field contours, as these do not guarantee any protective effect. ª Take the additional distances required for the application into account. Handling unmonitored areas There is an area behind the Safety Sensor that the Safety Sensor does not monitor. Unmonitored areas can also materialize, e.g. if you install a Safety Sensor on a rounded off vehicle front. It must not be possible to walk behind unmonitored areas. 2 1 3 Pic. 6.

Installation The shielding must be at least as high as the Safety Sensor's front screen and flush with the front housing edge. If you plan for a shielding that is still within the countersinking in the machine contour, the resolution of the protective fields must not be impaired at any accessible points. You require the reciprocal shielding with both horizontal and vertical alignment of the protective fields. 3 1 1 5 4 2 4 Pic. 6.

Installation Stationary danger zone guarding Pic. 6.7: Safety Sensor activates the stop and, with protective field with rear area protection, performs a presence-detecting function. Procedure ª Determine the height of the beam level. ª Calculate the necessary safety distance and determine the required additional distances for your application. ª Define the protective field limits and the warning field limits if required.
Installation 6.3.1 Beam level height The minimum height of the beam level depends on the Safety Sensor resolution. To detect a human leg a resolution of 50 mm is required at ankle height, and 70 mm at calf height (300 mm off the floor). Pic. 6.8: Beam level close to the floor Pic. 6.
Installation 6.3.
Installation C H H C Pic. 6.10: Beam level H = 300 mm, C = 1080 mm 6.3.4 Pic. 6.11: Beam level H = 875 mm to 1000 mm, C = 850 mm Machine response times, stopping time The Safety Sensor's rotary mirror rotates on its own axis every 40 ms. One revolution is a scan. At least two consecutive scans must be interrupted so that the safety-related switching outputs switch off. The Safety Sensor's minimum response time is therefore 80 ms.
Installation Application-conditional additional distances for safety distance "S" The protective field limits must be defined so that the calculated safety distance "S" to the point of operation, extended by the additional distances, is complied with "everywhere". Where this is not possible or does not make sense, you can use hard guards as supplementary measures. 1 D 2 RG S D S S D 3 4 Pic. 6.
Installation measurement error Biggest protective field radius RG without additional distances Additional distance ZSM < 3.5 m 83 mm ≥ 3.5 m 100 mm ª Avoid retro-reflectors at the beam level behind the protective field limit. If this is not possible, add another additional distance ZREFL of 100 mm. 6.3.6 Minimum distance "D" to the protective field contour The minimum distance "D" is the distance between point of operation and protective field contour.
Installation Stationary point of operation guarding 1 2 Pic. 6.13: The Safety Sensor takes over the stop-activating and presencedetecting function if walking behind the protective field is not possible. 1 Safety Sensor 2 Reference contour The following resolutions are required: • Detection of an adult's hand: 30 mm • Arm detection: 40 mm The required finger protection is ensured here by an additional distance "C", which depends on the resolution, in addition to the safety distance.
Installation 6.4.
Installation Machine response times, stopping time The Safety Sensor's rotary mirror rotates on its own axis every 40 ms. One revolution is a scan. With each additional scan the response time T1 increases by 40 ms. With K = 2000 mm/s approach speed this corresponds with an increase in the safety distance of 80 mm per additional scan. With K = 1600 mm/s it is 64 mm. ª Select a response time T1 of at least 80 ms or higher.
Installation 6.4.4 Protective field and reference contour With a vertical protective field you must define at least two sides of the protective field contour as reference contour in accordance with IEC/EN 61496-3. The objective is to monitor the position of the protective field with regard to its marginal area. If the arrangement misaligns and the distance of the Safety Sensor to the reference surface changes as a result, switch the safety-related switching outputs off. e 3 4 1 S 5 e 2 1 Pic. 6.

Installation The vertical protective field of the access guarding only detects people during passage through. After the passage a start/restart interlock must ensure that the dangerous movement does not start again automatically. Safety Sensors with a > 40 mm resolution are suitable for finger, hand and arm detection! The required protection for these body parts must be ensured with an additional distance C = 850 mm in addition to the safety distance. This distance is equivalent to average arm length.
Installation Machine response times, stopping time The Safety Sensor's rotary mirror rotates on its own axis every 40 ms. One revolution is a scan. An object must be detected in at least two consecutive scans so that the safety-related switching outputs switch off. The Safety Sensor's minimum response time is therefore 80 ms.
Installation 6.5.3 Protective field and reference contour With a vertical protective field you must define at least two sides of the protective field contour as reference contour in accordance with IEC/EN 61496-3. The objective is to monitor the position of the protective field with regard to its marginal area. If the arrangement misaligns and the distance of the Safety Sensor to the reference changes as a result, switch the safety-related switching outputs off. 1 4 2 3 5 Pic. 6.
Installation 6.6 Mobile danger zone guarding on AGVs Danger zone guarding protects people and objects that are in rooms in which vehicles move in, e.g. automated guided vehicle systems (AGVs). WARNING Danger of injury because of insufficient vehicle stopping distance ª The company operating the machine must use organizational measures to prevent people from entering the protective field of the vehicle from the sides or being able to move towards an approaching vehicle.
Installation 200 D B · L1 · L2 Vmax· (T1 +T2 ) DA D ZGES Pic. 6.17: Mobile danger zone guarding, required minimum distance D calculation ª Configure an upstream warning field that reduces the vehicle's speed. A full brake with a subsequent interruption of the protective field is then executed moderately and is less demanding on the vehicle's drives. ª Dimension the minimum distance D for the maximum speed as if the speed reduction initiated by the warning field had not happened.

Installation 6.6.4 Test mode for MotionMonitoring You require a special test mode to be able to check the MotionMonitoring function with the daily function check. Configure this test mode in the control system as follows: • Control system selects protective field 1 • Control system moves vehicle with speed for protective field 2 Alarm output 2 must signal that the speed will be exceeded.
