Project planning
This chapter includes important information about the proper integration of the UE410
Safeguard Detector Box safety system for planners, developers, and designers.
4.1
Safety
DANGER
Dangerous state of the machine
b
Make sure that the dangerous state of the machine is and remains switched off
during mounting, electrical installation, and commissioning.
b
Make sure that the safety evaluation module outputs do not affect the machine
during mounting, electrical installation, and commissioning.
DANGER
Hazard due to lack of effectiveness of the protective device
If insufficiently mounted or subjected to excessive vibrations, the sensors may become
detached or damaged.
It is possible for people to enter the hazardous area when the machine is running.
b
Where necessary, take suitable vibration reduction measures.
DANGER
The path of the beam between the sensor and the object being detected must always
be kept free and must not be disrupted or manipulated by any other objects.
4.2
Prerequisites
Structural prerequisites
The system only detects the surfaces of objects and not intervention by a person into
the hazardous area of the machine. For this reason, ensure that the detected object
covers the hazardous area in a manner that sufficiently prevents access or interruption.
The distance between the object (e.g.,
carton blanks) and the machine must not be so
big that an interruption by a person is possible or else there may still be a hazard
despite an object having been detected (which is the movable physical guard).
If the object moves to the side in the magazine, an interruption opening may be cre‐
ated, which, in some circumstances, may not be detected by the sensors. Correspond‐
ing countermeasures must be taken by the machine user.
Optical properties of objects
DANGER
Transparent objects (film packing , bottles, etc.) may cause availability problems as a
result of their direction-changing effect on light and may lead to safety-relevant incor‐
rect switching. For this reason, such objects must be kept out of the sensing range of
the sensors.
The objects to be detected must have the following properties:
•
The remission of the objects must be between 6
% and 90
% of a diffusely scatter‐
ing nature. This corresponds to black to white carton surfaces.
•
Very dark and retroreflective or shiny objects may cause availability problems.
