The reduced resolution function can only be used with the C4000 Advanced with a phy-
sical resolution of 14 mm and 20 mm.
The first beam of the light curtain (close to the 7Csegment display) must not be inter-
rupted. Otherwise, the safety light curtain will change to red.
The system response time does not change under reduced resolution.
You cannot combine the function Reduced resolution with the function Floating
blanking with partial object monitoring (see page 32).
With reduced resolution, the 7Csegment display indicates as soon as sender and re-
ceiver are aligned.
Check the minimum distance!
The minimum distance required under reduced resolution depends on the effective
resolution.
If required, recalculate the minimum distance and readjust it on the machine.
Example: – physical resolution 14 mm
– resolution reduced by 1 beam
– effective resolution 22 mm
Calculate the minimum distance with a resolution of 22 mm. (See page 40.)
Mark the effective resolution on the information label “Operation with reduced
resolution or blanking …” on the related sender and receiver.
Warning: During operation with “Reduced resolution” or “Blanking” the minimum
distance that corresponds to the modified resolution is to be observed.
