4.5
Testing plan
The manufacturer of the machine and the operating entity must define all required
thorough checks. The definition must be based on the application conditions and the
risk assessment and must be documented in a traceable manner.
The following tests must be planned:
•
Test during commissioning and in certain situations
•
Regular thorough checks
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
configured resolution.

4.5.1
Test during commissioning and in certain situations
Minimum requirements
The protective device and its application must be thoroughly checked in the following
situations:
•
Before commissioning
•
After changes to the configuration or the safety function
•
After changes to the mounting, the alignment, or the electrical connection
•
After exceptional events, such as after manipulation has been detected, after
modification of the machine, or after replacing components
The thorough check ensures the following:
•
All relevant regulations are complied with and the protective device is active for all
of the machine’s operating modes. This includes the following points:
°
compliance with standards
°
correct use of the protective device
°
suitable configuration and safety function
°
correct alignment
•
The documentation accurately reflects the state/condition of the machine, includ‐
ing the protective device.
•
The verified configuration report matches the desired project planning (
ing the configuration in Safety Designer", page 47
The thorough checks must be carried out by qualified safety personnel or specially
qualified and authorized personnel, and must be documented in a traceable manner.
Recommended thorough checks
In many cases, it makes sense to carry out the following thorough checks during
commissioning and in certain situations:
•
Test of the relevant points on the checklist,
see "Checklist for initial commissioning
•
"Visual check of the machine and the protective device", page 36
•
"Thorough check of the principal function of the protective device", page 34
•
"Thorough check of the area to be protected", page 35
•
Instruction of the operators in the function of the protective device
