3.2. Programmes
You can either work in the standard mode or access specially defined placing
programmes through PLU. The standard mode makes it possible to combine basic
functions such as stacking, long-shingling, cross-shingling or circular shingling with the
following parameters: number of slices, stroke speed and number rows/stacks.
3.2.1. Slicing in the Standard Mode (PLU=0000)
3.2.1.1. Stackinging
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 plus/minus 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: the machine then uses the calibre recognition option to calculate the best
placing point).

3.2.1.2. Long shingling
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 programme. 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:
the machine then uses the calibre recognition option to calculate the best placing point).
Example:

Page 19
Operation
3.2.1.3. Cross shingling
The cross shingling 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 programme. 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:
the machine then uses the calibre recognition option to calculate the best placing point).
Example:
Select function
“Cross shingling”
3.2.1.4. Circular shingling
Circular shingling 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 function
“Circular shingling”
19
Page 20
Operation
3.2.1.5. Offset Function
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.

“Long shingling“ function, 3 rows of 8 slices, which is programme “P3”.
On changing functions, i.e. by pressing a different button, e.g. Stacking, the placing
pattern is set for the corresponding function.
The example above would result in the following stacking pattern: 2 stacks of 10 slices.
It is possible to save the various parameters of a function individually by pressing the

3.4.2.1. Placing Format
The machine can determine the calibre of the food placed on it. It bases all its
calculations on a round calibre. You can therefore specify the placing format, so the area
in which the sliced food is to be placed, through the parameters “Length (L)“ and “Width
(W)”.
30
Page 31
Operation
If, for example, you enter W = 200 L = 200, the sliced food would be placed on a square
of dimensions 200 mm x 200 mm.
Example:
You want to portion salami decoratively on a tray with dimensions
210 x 210 mm.
To make sure that the tray is covered completely, you make the following settings:
Width 210 mm
Length 210 mm
The circular fan therefore has a 210 mm outside diameter and is placed centrally onto
the tray.
Food dimensions
H
B
3.4.2.2. Calibre mode
The machine has a calibre recognition function. Its calibre measuring device measures the
greatest length of the cross section of the product parallel to the carriage section.
This value is used for subsequent tasks
x Adjusting the carriage stroke path
(small product = small strokes | large product = large strokes)
x Positioning on the tray
Exact placing on packaging such as film, paper or a tray
You can use the menu controls to set the calibre recognition function to different modes:
a) Activation of calibre recognition “Auto”
In this mode, the placing pattern is calculated automatically using the parameters,
product width (B) and preset tray dimensions. The fanning distance, the distance
between rows and the initial placing position on the tray are calculated by the software.
The carriage travel is automatically adjusted to fit the registered width. That means that
two short strokes are used for small calibres and longer strokes are used for larger
cutting widths.
31
Page 32
Operation
b) Mode “Semi”
In this function, the placing positions in “X“ are calculated by the calibre recognition.
Parameters in “Y”, such as fanning distance for long fanning, are predetermined values
that can only be changed in parameter programming.
Y start
dist lengt
x
c) Deactivate “OFF”
The machine now operates with the preset fanning distance and initial position of the
first placed slice. The carriage travel remains constant, regardless of the calibre.
d) Partial activation “Height XXX”
Some products (flat, long products such as bacon) require the specification of the product
height. The calibre recognition only registers the product length and assumes that
product height and width are identical. This means that the fanning distance can be too
small for flat products, because the machine selects a fanning distance that is too small
for the entered product height for the assumed larger slices to be placed within the set
tray dimensions. The machine operates with numerical values in steps of 5 mm. These
values can be selected with the arrow keys.
Example: A piece of bacon with a height of approx. 40 mm is assigned the value 40.
y
3.4.2.3. Counting mode
The counting mode specifies whether a placing pattern based on the specified basic
functions is to be placed once (normal mode) or is to be repeated (continuous mode).
Example for normal mode:
32
Page 33
Operation
Basic function settings
Stacking – 10 slices – 4 stacks (= pressed “X button“ 3 times)
When it is started, the machine slices 4 stacks of 10 slices and places them on the table.
Then the machine stops.
Example for continuous mode:
Basic function settings
Stacking – 10 slices – 4 stacks (= pressed “X button“ 3 times)
When it is started, the machine places 4 stacks of 10 slices on the table.
The machine then returns to its initial position and repeats the cutting process.
It continues to do this until one of the following events happens:
x The specified number of portions has been sliced.
x All of the food has been sliced.
x The operator cancels the slicing process.
You can specify the portions in continuous mode (repeat mode).
To do this, use the -/+ arrow buttons to specify the number of portions.
If you specify “0”, the machine will repeat the process until the food has been sliced or
the operator cancels the slicing process.
Another way to modify the continuous slicing mode is to add pauses between individual
portions. The pauses can be used to remove one portion from the table and add a new
film or tray for a new portion on the tray.
3.4.2.4. Pause
This menu item only appears if the continuous mode is active.
This is where you can define the pauses between the individual portions by using the -/+
buttons.
3.4.3. Slicing in the PLU Mode
Customer-specific placing patterns can be stored in the PLU programmes.
Specify “Slicing in Standard Mode” when you are preparing the machine and when you
feed in the food to be sliced.
From the programme selection onwards, proceed as follows:
33
