SICK UE410-SD, Operating Instructions Manual, Page: 15 / 56

A thorough check must be carried out during commissioning and following modifica‐
tions,
see "Validation", page 29 .
In many cases, depending on the application conditions, the risk assessment deter‐
mines that regular checks are required,
see "Recommendations for regular checks",
page 15 .
4.6.1 Recommendations for regular checks
In many cases, depending on the application conditions, the risk assessment deter‐
mines that regular checks are required.
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 definition of the necessary intervals and reasons is dependent on vibrations on the
machine, among other things, which can be transferred onto the sensors.
Possible regular thorough check intervals or reasons:
• When the batch is changed
• When the system has been switched off because no object has been detected
(e.g., when the carton magazine is empty)
• During repair or maintenance breaks
In many cases, it makes sense to carry out the following checks regularly:
•
Visual check of the machine and the protective device , page 15
•
Thorough check of the principal function of the protective device , page 16
•
Inspection for whether the sensors are still in the correct position
•
Thorough check of the relevant validation points, see "Validation", page 29
•
Thorough check of the relevant points on the checklist, see "Checklist for initial
commissioning and commissioning", page 48
If a thorough check discovers a fault, the machine must be shut down immediately. In
this case, the mounting and electrical installation of safety system must be checked by
appropriately qualified safety personnel.
4.6.2 Carrying out thorough checks
Visual check of the machine and the protective device
SICK recommends the following procedure:
b
Check whether the machine or the protective device has been modified or manipu‐
lated so that the effectiveness of the protective device may be impaired.
b
In particular, the following points must be checked:
°
Has the machine been retrofitted?
°
Have machine parts been removed?
°
Have modifications been made to the surroundings of the machine?
°
Are there any defective cables or open cable ends?
°
Has the protective device been completely or partially dismantled?
°
Is the protective device damaged?
°
Is the protective device severely contaminated?
°
Are the front screens of the sensors contaminated, scratched, or destructed?
°
Has the alignment of the sensors been changed?
°
Are there any objects (e.g., cables, reflective surfaces) in the detection zone?
If one of the points applies, the machine must be shut down immediately. In this case,
the machine and the protective device must be checked by appropriately qualified
safety personnel.
