4.5 Testing plan
The protective device must be tested by appropriately qualified safety personnel when
commis
sioning, after modifications and at regular intervals.
The regular thorough checks serve to verify the effectiveness of the protective device
and discover defects due to modifications or external influences (such as damage or
manipulation).
The manufacturer and user must define the type and frequency of the thorough checks
of the machine on the basis of the application conditions and the risk assessment.
Determination of the thorough checks must be documented in a traceable manner.
•
A thorough check must be carried out during commissioning and following modifi‐
cations, see "Thorough check", page 119
•
The regular thorough checks on the safety laser scanner must fulfill certain mini‐
mum requirements, see "Minimum requirements for the regular thorough check",
page 59
•
In many cases, depending on the application conditions, the risk assessment
determines that further thorough checks are required, see "Recommendations for
further thorough checks", page 59
A test object is required for some thorough checks. An optically opaque cylinder with a
black surface can be used as a suitable test object. The diameter must match the con‐
figured resolution.
4.5.1 Minimum requirements for the regular thorough check
DANGER
H
azard due to lack of effectiveness of the protective device
Persons and parts of the body to be protected may not be recognized in case of non-
observance.
b
The thorough checks must be carried out at least annually.
b
The thorough checks must be carried out by qualified safety personnel or specially
qualified and authorized personnel and must be documented in a traceable man‐
ner.
The following thorough checks must be carried out at least once a year:
•
"T
horough check of the principal function of the protective device", page 60
•
Thorough check of the detection capability (resolution) in the context of the "Thor‐
ough check of the area to be protected", page 60
If a thorough check reveals a fault, the machine should be shut down immediately. In
this case, the mounting and electrical installation of the safety laser scanner must be
checked by appropriately qualified safety personnel.
4.5.2 Recommendations for further thorough checks
In many cases, depending on the application conditions, the risk assessment of the
mac
hine determines that further thorough checks are required or that some thorough
checks must take place more frequently.
In many cases, it makes sense to carry out the following thorough checks together with
the regular thorough check:
•
"Thorough visual check of the machine and the protective device", page 61
•
"Test of the contour detection field", page 61
•
Thorough check of the relevant points on the checklist, see "Checklist for initial
commissioning and commissioning", page 182
