All Wulftec automatic machines are equipped with a diffuse
photoeye on the carriage, for load height sensing for which you have
a switch. A second photoeye may be located on the top
platen. It is this photoeye that will override the carriage photoeye
when top platen is used. These models have a reflector on carriage
cover. This allows for variations in load heights, while maintaining
the predetermined "Overwrap" setting. All
machines are equiped with manual override (limit switches)
