All ANIS balers are supplied as standard with 2 sets of photo-electric cells, which are mounted in the hopper chute. The photo-electric cells detect the height that the material will reach, as a result of which the compaction cycle gets commences.
Depending on the type of material that is to be compacted, filling takes place on the flap or on the bottom: heavy material, such as magazines, is filled on the bottom, and light material such as cardboard, on the flap.
It is possible to install an extra set of photo-electric cells.
