■ Function
The laser scanner is an optical, contact-free surface scanner –
designed primarily for operator protection.
Using a laser diode with transmission optics, the laser scanner
continuously generates bundled light pulses that are scattered
throughout the operating range by an integrated rotating mirror.
If objects or persons enter the field, it evaluates the reflected
light pulses and continuously calculates the exact position coor-
dinates on the basis of the light propagation time. If the defined
personnel protective field is penetrated, the laser scanner stops
the machine immediately (within the system response time).
The Stop function is reset when the protective field is free again,
either automatically or following acknowledgement (depending
on the operating mode).
The operating range of the laser scanner spans 190° and is
subdivided into angle segments of 0.36°.
The scan rate is 25 scans/second, i.e. one light pulse every
40 ms in each segment. A special algorithm ensures that objects
larger than 70 mm (this corresponds to the scanner resolution)
can be reliably detected and that contamination (e.g. dust) does
not reduce system availability. The laser scanner detects people
(even if they are wearing dark clothing) at a distance of up to 4 m
(failsafe). People or objects can, however, be detected at a dis-
tance of up to 15 m so that a warning can be output, for example
(not safety relevant).
Four protective field/warning field pairs
Four variable protective field pairs for the personnel protective
field and warning field, which can be easily set on the PC, ensure
that the laser scanner can be adapted to suit any requirement.
It can be implemented in stationary applications (machines and
installations) or mobile applications (vehicles, automatic guided
vehicle systems, or shifting units). In the case of a robot, for ex-
ample, different operating ranges can be protected, whereby
the laser scanner operates in succession with regard to time and
space. In the case of automatic guided vehicle systems, four
programmable protective fields can be protected (e.g. rapid
travel, slow travel, turning left, turning right).
LS4soft operator software
Thanks to the PC operator software LS4soft, it could not be
easier to optimize the laser scanner settings. The following
functions have been integrated:
• User-friendly configuration of the protective field using a PC
or laptop
• Configuration of additional functions, such as protective field
selection, restart inhibit, etc. by means of a software wizard
• Comprehensive range of displays, e.g. defined protective
fields, current scan contours, system settings, etc. reliable,
password-protected access with different authorization levels
• Executable under Microsoft Windows 95/98/NT/2000/XP
The operator software is supplied with the laser scanner.
