Blanking Programming unit
The blanking function allows selected areas of the sensing field to be disabled. This is useful for those applications in which objects, such as work piece supports protrude through the curtain. The B-SERIES and GS 140 SERIES light curtains are capable of being blanked for fixed and floating blanking.
The beam blanking function is set up using the BPU Programming unit. This device is used to teach the sensing unit when fixed blanking or floating blanking is required. One programming unit can be used to program any number of light curtains.
Two versions are available. For the B-SERIES light curtain model number BPU-2 (part no. 0953) is required. For the GS 140 SERIES light curtains model number BPU-4 (part no. 0753) is required. The programming units are not interchangeable from the B series to GS series.
