30 Light Array Operation
NOTE!
The safety field’s pilot beam may not be continuously interrupted.
5.3.0.4 Calculating Safety Clearance
Safety clearance is calculated with the same method used for a non-blanked Safety Light Array. Mechanical cur-
tains must be utilized in order to assure that fix blanked beams cannot be penetrated.
When this operating mode is used, beam clearance in accordance with EN ISO 13855 must always be adhered to
(see also section 3.3).
5.3.5 Reduced Resolution
Safety Light Array resolution can be reduced with the help of the reduced resolution function. As opposed to Light
Arrays with mechanically reduced resolution, electronically reduced resolution provides for significantly greater
functional reserves. This is due to the fact that objects which are smaller than the selected resolution do not cause
the safety output to switch where electronically reduced resolution is utilized.
The required resolution is configured by means of teach-in with the desired objects.
Resolution is set such that the objects can pass through the safety field at any point without causing the safety
output to switch. With the help of the table, the displayed value can be converted to the resulting resolution in
order to determine safety clearance.
5.3.0.6 Principle
A certain number of adjacent beams can be interrupted with reduced resolution without causing the safety output
to switch (see table). Light curtain resolution is thus changed.
In this way, objects which are smaller than the reduced resolution value can be passed through the safety field
Reduced Resolution =
3 beams interrupted
If an object which is larger than the selected resolution passes through the safety field (e.g. intrusion), the safety
output is switched!
Safety Light Array resolution is identical to electronically reduced resolution in the “reduced resolution”
operating mode (see table).
Reduced Resolution =
3 beams interrupted
Additionally interrupted beams!
