Access guarding by passage monitoring
Access guarding by passage monitoring (whole body trip control) is a suitable method
when the access to a machine or to a hazardous zone can be precisely defined in
structural terms, and there is no other unprotected access to the area. It is best to mount
the laser scanner above the passage in question, in vertical alignment. In order to secure
the protective equipment, laser scanner and fence against inadvertent misadjustment and
manipulation, the detection zones of the
SD3-A1
must be defined on the basis of a
reference boundary. In this operating mode, the scanner will use the polled environment
as a reference and so check for changes in the layout of the protective equipment, as well
as checking every one of the individual measurements it carries out with a view to
detecting an intrusion. An example of the configuration of the
SD3-A1
to give access
protection by passage monitoring will be found in Chapter 5.5.
