Location planning The following observations take into account only the vehiclespeed, not the speed of a running person. The reason is that itis assumed that a person approaching the vehicle recognises the danger and at least stands still. Scanning level HVehicle Mounting of a FLSC on a vehicle Mounting height: Due to the intrinsic movement of the professional scanner in the mobile ap-plication, a resolution of 70 mm is adequate for detection ofpersons in mobile applications (stationary application: 50 mm).For this reason, the mobile application requires no increase protective field ranges over 2.90 m.The sensor is to be calibrated in accordance with EN 1525 suchthat a body of maximum 200 mm height under all circum-stances is detected in the protective field range necessary tobring the vehicle to a safe stop. (Recommendation: setting to150 mm height).The scanning plane should not be below 100 mm, as the in-creased dust concentration on the floor could cause the scan-ner to shut off unintentionally.
Pre-setprotectivefield length150 mmVehiclemax. 272 mm Mounting height Mounting mode: A basic distinction is made between two modes of mountingthe FLSC:Protruding front mountingThe dead zones created at the sides of the sensor in protrudingfront mounting must be eliminated by mechanical trim covers orswitch strips, or the vehicle must not be accelerated to speedsabove 0.3 m/s in less than three seconds.Integral in-vehicle trim panel:The sensor is installed such that no dead zones, or no deadzones > 70 mm, are created to the side of it. The vehicle may then be accelerated to a speed of 0.3 m/s within one second.In order to meet this condition, the FLSC must not protrudemore than 109 mm over the front edge of the vehicle.If the close-up zone of the sensor (4 cm wide area measuredfrom the front screen outer contour) is either rendered inacces-sible (e.g. by a bar or undercut) or is monitored by a proximityscanner or a switch strip with a 4 cm detection range, thevehicle may be accelerated at will.
