AS-Interface laser scanner LS4

■Function

Function principle

Protection and warning field pairs

Bundled light pulses are created via a laser diode with coupled transmission optics. These are diverted by a rotating mirror in such a way that within 40 ms a light pulse is triggered in all angle segments (scan rate: 25 scans/s). If the light pulse hits an object or a person, the light is reflected and acquired and evaluated by

6the scanner.

Measuring pulse propagation time

The device has 4 switchable protection and warning field pairs.

LS4Soft operating software

The SIGUARD LS4 laser scanner must be parameterised using the associated LS4Soft software. The personal protection and warning fields required are set in this manner. Also configuration parameters, such as automatic/manual start, response time and restart time can be parameterised.

The SIGUARD LS4 laser scanner operates by measuring the pulse propagation time. When extremely short light pulses are emitted, a time difference occurs between the transmitted and received light pulse. The propagation time of the light pulse is a direct measurement of the target distance.

The operating range of the scanner (190°) is subdivided into angle segments of 0.36°.
