This machine is constructed in accordance with the European regulations indicated in the
conformity and manufacturer’s declarations.
In addition to this instruction manual, please also observe all generally accepted, statutory
and other legal requirements, including those of the user’s country, and the applicable pollu-
tion control regulations! The valid regulations of the regional social insurance society for oc-
cupational accidents or other supervisory authorities are to be strictly adhered to!
● The machine may only be operated by adequately trained operators and only after these
have read the appropriate Instruction Manual!
● The danger and safety instructions attached to the machine must be followed!
● The machine may only be used for the purpose intended and may not be operated wit-
hout its safety devices. All relevant safety regulations must be adhered to.
● When changing the feed rollers or the hot air nozzle, when leaving the machine unatten-
ded or during maintenance work, the machine must be disconnected from the power
supply by operating the main switch or by pulling out the plug!
● The daily maintenance work may only be carried out by appropriately trained personnel!
● During repair and maintenance work on pneumatic devices the machine must be discon-
nected from the pneumatic supply system! The only exceptions permitted are during ad-
justment work and function tests carried out by appropriately trained personnel!
● Repairs and special maintenance work may only be carried out by qualifi ed service staff
or appropriately trained personnel!
● Work on electrical equipment may only be carried out by appropriately trained personnel!
● Work is not permitted on parts and equipment which are connected to the power supply!
Exceptions to this rule are found in the regulations EN 50110.
● Modifi cations and alterations to the machine may only be carried out under observance
of all the relevant safety operations!
● Only spare parts which have been approved by us are to be used for repairs! We draw
special attention to the fact that spare parts and accessories not supplied by us have not
been subjected to testing nor approval by us. Fitting and/or use of any such parts may
cause negative changes to the design characteristics of the machine. We shall not accept
any liability for damage caused by the use of non-original parts.

Installation and commissioning
8 Installation and commissioning
After the machine has been unpacked, check it for any damages caused during transportati-
on. If there are any damages, please notify the transport company and your
local PFAFF agency.
The machine must only be installed and commissioned by qualifi ed personnel.
All relevant safety regulations must be strictly adhered to!
8.01 Installation
Suitable connections for electricity and compressed air must be available at the machine’s
location (see Chapter 3 Specifi cations).

Installation and commissioning
8.02 Commissioning
● Examine the machine, in particular the electric leads, for any damage.
● Clean the machine thoroughly, also see Chapter 12 Maintenance.
● Connect the machine to the electrical network and have specialists examine, whether the
machine can be operated with the available voltage and whether it is properly connected.
Do not operate the machine if there is any discrepancy!
The machine may only be connected to an earthed socket!
● Connect the machine to the compressed
air system. A pressure of 6 bar should
be displayed on the manometer. If necessary, set this value, see Chapter 12.02

The compressed air quality
influences the service life of the
heating cartridge in the air
heater. If the air is very damp,
a compressed air cold drier with
preliminary filter and secondary
fine filter must be installed in
front of the heat-sealing
machine

Installation and commissioning
8.03 Switching the machine on/off
● To switch on the machine, turn the main switch to the "I" position, see Chapter 7.02 Main
switch.
● After the boot operation of the control unit, call up the "basic position" function.

Danger of damage to the heating cartridge!
The hot air temperature must not exceed 100°C when switched off!
Before switching off the compressed air system, wait until the blast air swit-
ches off automatically!
● Turn the main switch to the "0" position, see Chapter 7.02 Main switch.

Preparation
9.02 Selecting the production type:
The program selection function is used to choose between the types of production
- Manual heat sealing (Chapter 10.02)
- Programmed heat sealing with individual programs (Chapter 10.04) and
- Programmed heat sealing with sequences (Chapters 10.06).
The types of production listed above, particularly their functions, are explained
in more detail in Chapter 10 Heat sealing.
● Switch on the machine.
● Call up program selection.
Example 1
● Call up manual heat sealing, the production type, "Manual Heat Sealing" is activated.
or
● Select the desired program number.
(Selection can also be made by entering the program number on the fi gure panel
directly.)

● Call up sequence selection.
● Select desired sequence number.
(Selection can also be made by entering the sequence number on the fi gure panel
directly.)

Preparation
After selecting "Manual Heat Sealing", also see Chapter 9.02 Selecting the production
type:, following values can be entered depending on the sealing method:
- Sealing temperature
In addition to the set sealing temperature, the value for the parameter (off = heating off)
appears in the appropriate symbol as well as the actual sealing temperature.
- Sealing speed
In addition to the sealing speed, the value for the difference in speed in % between the
top and bottom feed rollers appears in the appropriate symbol.
- Type of heating wedge or heating nozzle with hot air volume
- Roller pressure
The values can be entered directly by pressing the appropriate key symbol.
In Programmed Heat Sealing the direct input of sealing parameters is not
possible. The alteration must be made in the appropriate sealing program,
see Chapter 10.03 Creating/altering a heat sealing program.
After switching the machine on, after the "pause" function or after detection of
an error, the heating element is switched off (parameter "OFF"). After changing
the sealing temperature, pressing the "start" function or after operating the
pedal, the heating element is switched on again.
