SYMBOLS INDICATING PROGRESS OF THE PACKING CYCLE
Cycle Progress Indicator
• This symbol rotates during the packing cycle
Vacuum Process
• In the presence of a sensor, the vacuum measurement is digitally displayed.
• When operating a time-based program, the vacuum measurement is indicated by
the analog vacuum gauge
Vacuum Plus (10.4)
• With a sensor controlled machine, a number of seconds may be added to the vacu-
um process after the programmed pressure value has been reached
MAP Gassing (optional; for sensor-based operation only) (10.5)
• During the MAP (Modified Atmospheric Packaging) gassing process, the package is
vacuated down to a programmed value, for instance 600 mbar; the vacuum meas-
urement is shown in the display
• The gassing time count-down is displayed in seconds, or the increasing pressure is
displayed in mbar or %
Sealing (page 10.6)
• The package is heat-sealed for a programmable number of seconds (single-double-
clean cut)
Clean Cut Controlled Seal (optional) (10.6)
• Special sealing method, by which a second heating wire scores the package, making
it easy to remove the excess packaging material
• The additional wire is time-controlled independently; the scoring time is displayed
Soft-Air (optional) (10.8)
• The vacuum chamber is aerated more slowly. This allows the packaging material to
gradually conform to irregularly-shaped products and prevents sharp objects from
puncturing the bag
• The aeration time count-down is displayed in seconds, or the gradually increasing
pressure is displayed in mbar or %
Multi-Cycle (for MAP applications only) (10.9)
• After the package is vacuated down to the programmed value, it is gassed and revac-
uated a number of times. The objective of this procedure is to minimize the amount
of oxygen remaining in the package
• The number of cycles is counted down in the display
Cool-Down/Oil Dehumidification Phase (10.10)
• When turning off the machine with the button, the
symbol will start blinking in the LCD display and the pump
will stop after about 4 seconds
• Press the button a second time and the pump will stop immediately
• Close the lid and the machine will initiate the cool-down phase by performing a
number of vacuum cycles before turning off automatically
• These additional cycles allow any moisture in the oil of the pump to evaporate. This
increases the longevity of the machine and minimizes the need for oil changes and
maintenance

• After a number of operating hours or packing cycles, the
service symbol will briefly appear on the display when
turning on the machine. In addition, the display will
indicate how many hours or cycles remain before an oil change is required
• After reaching zero, the display will indicate the negative number of exceeded oper-
ating cycles or hours
• To reset the service interval counters after the oil change, press and hold the
button for 5 seconds
9. Standard Vacuum Pump Settings:
1. Pump stops after vacuum cycle
2. Pump runs continuously; stops after 15 minutes
• The pump of mobile packaging machines M1, M2 and M4, M5, M6, M7, M8, as well as the pump of
double-chamber units D1, D3, D4 and D6, runs continuously. After completion of a packing cycle, the
pump will stop after 15 minutes of inactivity.
• The pump of table units T2, T3, T4 and T5 starts when the cover is closed; the pump stops when the
cover is opened again.
• The 21m3 pump of the M3 continues to run, while the 40m3 pump stops between packing cycles
• These settings may be adjusted by the dealer in the Service menu
9.1. One-Program Control System
Stop the cycle and aerate:
• By pressing the button during the packing cycle, the active function is stopped, the chamber is
aerated and the cover opens. Subsequent functions in the cycle are cancelled
Stop the cycle and start sealing
• By pressing the of the sealing button , the vacuum function is interrupted and the program
jumps to the sealing function
9.2. Ten-Program Control System
Stop the cycle and aerate:
• By pressing the button during the packing cycle, the active function stops, the chamber is aerated,
and the cover opens. Subsequent functions in the cycle are cancelled
Stop the cycle and start sealing
• By pressing the button, the packing cycle is interrupted and the program jumps to the next func-
tion in the process

10. Further Explanation of Packaging Concepts
10.1. Sensor-Based Control
The actual air pressure in the chamber is measured by a sensor. The result of this measurement is digi-
tally indicated on the LCD display.
Normal air pressure is about 1000 mbar. The vacuum pump of the machine reduces this to about 2-5
mbar. Depending on the program, the pressure by which certain functions need to take place can be
programmed. Examples are MAP gassing and Soft-Air.
The air pressure in time-controlled machines is indicated by the analog vacuum gauge.
10.2. Time-Based Control
• The standard control of a One-Program machine, as well as a Ten-Program machine, is time-based
• The Ten-Program time based machine can be converted into sensor-based operation by ordering the
optional sensor kit
A time-controlled machine is programmed with a time value in seconds, according to
which a desired vacuum is reached. The vacuum measurement is indicated by the analog
vacuum gauge. The reading of the analog vacuum gauge is less accurate than the digital
reading of a sensor-controlled machine.
• The Ten-Program machine can be retro-fitted with a sensor kit at a later date. The control system rec-
ognizes the sensor and will automatically switch over to sensor-based operation
• In case the sensor should fail, the machine will automatically switch over to time-based operation
10.3. P H2O Program for Liquid Products
• Only for Ten-Program machines with sensor-based control
• Specially designed for the packaging of cooled liquid products like sauces and soups at temperatures
< 150C (600F)
Under normal air pressure (1000 mbar), water boils at 100o C. At that point, water transfers rapidly from
a liquid phase to a gas phase. At lower air pressure, boiling starts at a lower temperature as well as rapid
evaporation. To avoid product loss through evaporation and spillage, the P H2O program detects the point
of boiling and initiatese sealing function in the cycle. Since air is replaced by water vapor at this point, the
oxygen content in the package will be very low.
10.4. Vacuum Plus (seconds)
• Only for Ten-Program machines with sensor-based control
• Can be turned on or off in the Settings menu
After reaching a programmed vacuum pressure, the sealing function may be delayed by adding a pro-
grammable number of seconds to the vacuum process. This enables any air to escape from porous
products.
10.5. MAP Gassing (option)
• Only for Ten-Program machines with sensor-based control
• Can be turned on or off in the Settings menu
After reaching a programmed vacuum pressure, the package is filled with an inert gas,
such as CO2, nitrogen, oxygen, or a mixture thereof. This feature is either time or pres-
sure-controlled.

10.6. Sealing
The synthetic packaging material is melted shut by a heated sealing wire.
single seal
double seal
clean cut &
clean cut controlled
two-sided seal
• Single Seal
Only for T2. The package is sealed with a single sealing wire
• Double Seal
All other machines are equipped with a double sealing wire
• Clean Cut Seal (CC Seal)
One of the two heated wires is used to score the package. This makes it easy to remove the
excess packaging material. The package has one seal and a nicely trimmed edge.
• Clean Cut Controlled Seal (CCC Seal)
- Only for Ten-Program machines with sensor-based control
- Can be turned on or off in the Settings menu
Identical to the Clean Cut seal, with the only difference that the heating time for the scoring wire can
be programmed independently. This improves control over the scoring process. Typically used for shrink
bags.
• Two-Sided Seal
- Only for Ten-Program machines with sensor-based control
- Can be turned on or off in the Settings menu
The counter beam contains a sealing wire as well. Used for thick material or metallic packaging
materials, requiring additional heat to seal the bags.
10.7. Extra Sealing Pressure
During the sealing process, the package is held in place between the seal beam
and the counter beam. To assure a proper package seal, additional air pressure to
the sealing beam may be beneficial (maximum of 1 bar), for instance during MAP
gassing above 500 mbar.
• The M4-M8 and the D1-D6 models with the option Gas/MAP are standard
equipped with a compressed air inlet. Otherwise it can be easily retrofitted.
• Extra sealing pressure is not necessary and not available for the Table-Top, M1,
M2, M3
