Safeguarding Of Danger Points Based On Hand And Arm Detection - Siemens SIMATIC FS600 Instruction Manual

4.3

Safeguarding of danger points based on hand and arm detection

If the machine operator, in close proximity to the danger zone, needs to halt the
hazardous movement of the machine or to coordinate the handling of workpieces or their
removal from the machine, the machine must be provided with protection at the danger
point. To safeguard danger points in this way a protective system needs to be installed.
The SIMATIC FS660I Laser Scanner is certified as a system providing hand and arm
protection, and is able in such a situation to guarantee flexible safety conditions in the
workplace. This may be combined with alternation of the detection zones. In order to
safeguard the protective equipment, laser scanner and side-mounted panels (which
serve as a reference and provide additional access protection) against inadvertent
misadjustment or manipulation, the detection zones of the SIMATIC FS660I Laser
Scanner must be defined on the basis of a reference boundary.
An example of the configuration of the SIMATIC FS660I Laser Scanner for the protection
of danger points based on hand and arm protection may be found in Chapter 5.6.
