For fixed blanking, the desensitized area does
not move or change once configured. Means to
identify the desensitized area may include but
are not limited to:
• indicators within the electro-optical presence-
sensing device;
• signage or marking of the fixed blanked area;
• the physical location of the object in the
blanked area if movement or removal of the
object can be detected and results in a stop
command.
Means of supplemental safeguarding can
include:
• completely filling the fixed blanked area to
restrict access to the hazard;
• the electro-optical presence-sensing device
installed at a distance that accounts for the
worst case object sensitivity; (see 8.3.2.2) or
• alternate safeguarding may be provided to
prevent access to the hazard.
8.3.2.6 Components, subassemblies or modules
of the interface or machine control system shall
conform to the requirements of 6.1, or shall be
designed and constructed to meet the safety
performance level (risk reduction) as
determined by a risk assessment.
E8.3.2.6
See also, clause 5 and ANSI B11.0
(B11.TR3).
8.3.2.7 Bypassing of the presence-sensing
device shall comply with 6.6.
8.3.2.8 Muting of the presence-sensing device
shall comply with 6.7.
8.3.2.9 The RF presence-sensing device shall
not be adversely affected by changes around
the machine that may alter the sensitivity of the
device such that individuals are no longer
detected in the sensing field at the proper safety
distance.
E8.3.2.9 The RF presence-sensing device may
be affected by changes in the conditions around
the machine such as ambient conditions, the
placement of parts and tote boxes, grounding
conditions of the operator, or the movement of
industrial trucks. These changes should not
adversely affect the performance of the device.
