3.2 Programs
You can either work in the standard mode or access specially defined placing programs
using PLU. The standard mode makes it possible to combine basic functions such as
stacking, long-fanning, cross-fanning or circular fanning with the following parameters:
number of slices and number rows/stacks.
3.2.1 Slicing in the Standard Mode (PLU 0000)
3.2.1.1 Stacking
The stacking function enables stack heights of up to 60 mm.
This function is selected by simply pressing the stack button. The display shows the
symbol for stacking. You can preset the number of slices using the +/- buttons. If multiple
stacks are desired, you can increase the number of stacks with the X button. Up to 4
stacks are possible.
When making preparations, it is recommended to set the slice counter to “000”. In this
way, the maximum stack height is always achieved.
If stacks are to be generated on portioning units (foils, PE trays, foam trays, trays etc.),
you can enter the outer dimensions of the portioning units L x W for central placing.
(Option only HA 800: the machine then uses the calibre recognition option to calculate
the best placing point.)
Other Operating Controls

3.2.1.2 Long Fanning
The long fanning function is for placing the individual slices in rows parallel to the stop.
The number of rows can be set using the “X” button. Up to 4 rows are possible with the
standard program. When making preparations, it is recommended to set the slice counter
to “000”. The machine then fans multiple layers on top of each other.
If rows are to be generated on portioning units (foils, PE trays, foam trays, trays etc.), you
can enter the outer dimensions of the portioning units L x W for central placing. (Option
only HA 800: the machine then uses the calibre recognition option to calculate the best
placing point.)

3.2.1.3 Cross Fanning
The cross fanning function is for placing the individual slices in rows parallel to the chain
frame. The number of rows can be set using the “X” button. Up to 4 rows are possible
with the standard program. When making preparations, it is recommended to set the
slice counter to “000”. The machine then fans multiple layers on top of each other.
If rows are to be generated on portioning units (foils, PE trays, foam trays, trays etc.), you
can enter the outer dimensions of the portioning units L x W for central placing. (Option
only HA 800: The machine then uses the calibre recognition option to calculate the best
placing point.)
Example:
3.2.1.4 Circular Fanning
Circular fanning enables the slices to be placed in a circular pattern.
The diameter of the circle can be altered by adjusting the tray dimensions. In this way,
oval placing patterns are also possible.
Example:
Select
“Cross fanning” function
Select
“Circular fanning” function

Operation
20
3.2.2 Offset Function (Machines without Calibration
Recognition)
On machines without calibration recognition, the “Offset function” can be used to
slightly adjust the laying position on the tray, for example, a stack can be placed on the
left, in the centre or on the right of the tray.
Example:
The stacking function has been selected. If
the function button (stacking) is pressed
again, three bars appear in the display.
The plus “+” and minus “-” buttons can be used to
change the position of the highlighted bar and the laying
position of the cutting material is moved on the tray
correspondingly.
OFFSET FUNCTION CHANGE OF LAYING POSITION
Stacking Left, centre, right
Long fanning Left, centre, right
Cross fanning Rear, centre, front
Circular fanning Larger Ø, medium Ø, smaller Ø
