Double Feeding Detection Function
DEN
Machine detects Double Feeding by DEN function. The detection level can be selected
by DEN key depending on the density of the notes.
Four different levels can be chosen by pressing DEN key in the following sequence:
DEN-1
DEN-11
DEN-111
DEN-1111
OFF(Blank)
UV Detection Function (option)
UVD
UVD function is to detect the fluorescence on notes. A counterfeit note that generates
fluorescence under the ultraviolet rays can be detected when this function is set ON.
The machine will stop, showing message "CF1" . The suspected note is the last one in
the stacker. Take the suspected one away and press RESTART key to countinue the
counting. The suspected one isn't included in the counted result.
Four sensitivity levels can be selected by pressing UVD key.
UVD-1
UVD-11
UVD-111
UVD-1111
OFF(Blank)
DEN-1 → DEN-11 → DEN-111 → DEN-1111
Level 1: To count dark-colored (thick) notes.
Level 2: To count high density notes.
Level 3: To count median density notes.
Level 4: To count light-colored (thin) notes.
When counting very dark-colord notes or very thick notes, this
function should be turned off. But machine can not detect Double
Feeding.
UVD-1→ UVD-11 → UVD-111→ UVD-1111
Level 1: To count notes of the lowest UV sensitivity level.
Level 2: To count notes of middle UV sensitivity level.
Level 3: To count notes of high UV sensitivity level.
Level 4: To count notes of the highest UV sensitivity level.
Function inactive.
