2.1 Description of the functionality

2.1.1 Foreword

Application areas

The laser scanner SIMATIC FS600 is used for hazard protection. The laser

scanner, aligned horizontally in most cases, monitors the presence of

persons in the protected zone.

When using the laser scanner SIMATIC FS600, access to the hazardous

location must only be possible through the protected zone. A safe distance

must be kept between protected zone and hazardous location. The

distance is calculated according to the formulas in the specific machine

related European C standards or in the general B1 standard EN 999.

The relevant regulations of machine safety in Europe apply for the use of

distance scanners (e.g. laser scanner SIMATIC FS600), in particular:

• machinery directive 98/37/EC

• work equipment directive 89/655/EEC

Operating principle of the laser scanner SIMATIC FS600

The laser scanner SIMATIC FS600 is a distance scanner. It sends very

short laser pulses and measures the time until the pulse hits an object, as

well as its remission (diffuse reflection of a beam by a non-reflecting

surface) to the receiver in the laser scanner. The device uses this time to

calculate the distance between object and laser scanner. The sensor unit of

the laser scanner SIMATIC FS600 rotates and sends/receives a laser pulse

after each 0.36°. A circular sector of up to 190° is scanned in the center of

which the laser scanner is located.
