3.1 Speed Range & Capacity
3.1.1 Sealing Speed Range
The speed range available is between 2.7 - 22.2 m/min depending on bag thickness. Other
speeds outside this range are possible, to suit customer requirements.
3.1.2 Thickness of Film (Maximum):
Normal range of thermoweldable films up to 300 micron (1200 gauge or 12 mil).
3.2 Total Power Consumption
3584 watts (maximum).
3.3 Nett Weight
Sealingheadonly:77kg
Sealing Head with Adjustable Column and Trolley: 130 kg.
3.4 Voltage and Frequency
Voltage and frequency may vary ± 6%. It is important to be aware that a reduced voltage will
reduce the ‘Flat Out’ performance or maximum temperature. Also any deviation in Hertz will
affect the linear speed. If any conveyor running in conjunction with the machine is powered
by an induction motor, directly from the mains, then both units will usually be maintained in
synchronization.
3.5 Wiring
This machine may be hard wired or mains supplied via plug and socket, suitable for the
voltage and current requirements stated on the Machine Rating Plate.
3.6 Environmental Conditions
Compressed air must be clean, dried, filtered to at least 40 Microns, and supplied at 5.5 Bar.
3.7 Operating Temperatures
5°Cto35°C,
A LOW OPERATING TEMPERATURE WILL REDUCE THE ‘FLAT OUT’ PERFORMANCE.
3.8 Relative Humidity
85%(maximum).Storagewhennotinuseshouldbeat21°Cinadryindoorsituation.
If prolonged storage is anticipated, it is advised that the unit is thoroughly cleaned,
decommissioned and returned to its original packaging, or packaging of a comparable type.
3.9 Thermocouples
In the event of inaccuracy, it is possible to check the output voltage of the ‘K’ type
thermocouples at a given temperature. However, thermocouples either function correctly or
not at all, calibration is not possible.
3.10 PID Controllers
Calibration of the PID Controllers is not normally necessary. However, PIDs may be checked
for accuracy by substitution of a thermocouple simulator. Alternatively a D.C. millivolt source
may be used by ‘dialling in’ voltages that match the characteristics of a K type thermocouple.
It is also possible to check overall accuracy with an external temperature display. However, it
should be noted that the probe must be in exactly the same position as the thermocouple tip,
and even then, due to air flow characteristics, it is likely that a small variation will be evident.
Span and Zero adjustments are available, if required, via the PIDs menu system on ‘Level 3’
(further data available from Fischbein-Saxon Ltd if required).
If PID calibration shows a serious inaccuracy it should be returned to Fischbein-Saxon Ltd.

4.1 Work Flow
4.1.1 The unsealed bag is fed into the Sealer Guides (1) where it is gripped by two
belts and is carried through the Plough Section or Trimmer (if fitted).
4.1.2 Still gripped by the belts, the bag now passes through a Heating Section. (2)
Here, opposing streams of hot air strike the bag side along a narrow band,
causing a heated bond to be formed on the inside surfaces of the bag.
4.1.3 After heating, the bag immediately passes through two Pressure Rollers (3) to
complete the weld.
4.1.4 With the weld completed, the bags pass out of the sealer (4).
The Hot Air temperature is controlled by PID Temperature Controllers. These
continuously monitor the output temperature from the Heating Capsules and
adjusts it to that preset on the control panel by the operator.
WORKING FUNCTIONS
4 WORKING FUNCTIONS
The Sealer uses a patented system of hot air bag sealing which gives a high
sealing efficiency together with reduced setting up and maintenance times.

begin the run up to working temperature.
At the same time, controllers will show “8888”
immediately followed by current air temperature.
This indicates self-test procedure.

5.2.3 Raising the machine to correct working temperature from cold takes 2 - 3 minutes,
depending on required temperature.
Do not attempt to run bags until required temperature is reached.
See “PID CONTROLER - AUTOTUNE” section.
Note:
If only 2 PIDs are installed, PID 3 and PID 4 will be
dummies and will not show a display.
For L-R configuration, PID numbers will read from
the other end.

running in reverse direction, until the PID Display
indicates that the temperature has dropped to below
50°C. The machine will then stop automatically.

6 SETTING UP
A GOOD BAG SEAL IS OBTAINED BY THE VARIABLE INTERACTION OF
THREE OPERATING FACTORS ON THE MACHINE:
1) Throughput SPEED (A)
2) TEMPERATURE (B) of the Sealing Air.
3) The HEIGHT (D) of the Heating
Capsule Outlets (See Section 6.12).
4) CORRECT PRESSURE (C) between
the Pressure Wheels.
6.1 Throughput Speed
6.1.1 After installing the Sealer, check that the speed of the machine and the infeed
conveyor are synchronised.
6.1.2 If conveyor and machine speeds are not synchronised, the bags may tip, which in
turn will give partial or no sealing. This effect is most noticeable on narrower bags.
A
6.1.3 If the conveyor speed cannot be changed to correspond to the sealer, then the
sealer speed (If fitted) has to be changed to match the conveyor. This may require
the temperature to be adjusted for best seal.

6.2 Machine Positioning
THE INFEED CENTRE LINE OF THE MACHINE MUST BE DIRECTLY
ABOVE AND PARALLEL WITH THE CENTRE LINE OF THE CONVEYOR
6.2.1 The machine must be correctly levelled on a
sound base by four levelling screws S.
6.2.2 Height is adjustable by the electric column T.
6.2.3 When setting up the conveyor and sealer, it is
critical that the lines A-Aand B-B are parallel.
6.3 Bag Height
6.3.1 The required bag height measurement His taken from the top
surface of the conveyor belt to the underside of the machine infeed.
IMPORTANT
The top of the bag, when on the conveyor,
should be approximately at waist level to the operator.

6.5 PID Controller - General
The PID Controller is a programmable unit giving cyclic monitoring and fine
control of Sealing Air Temperature
TEMPERATURE RANGE 0 - 400°C
All controllers, whether fitted to new machines or supplied as replacement units, are
preset to 150°C. This setting gives a convenient start point in the sealing process to
determine the air temperature required for various applications.
6.5.1 PROGRAMMING
Incremental in single degree or multi-degree steps by use of the control buttons
referring to the instructions on the following pages.
6.5.2 AUTOTUNE
When Autotune is completed, temperature is maintained to within ±2°C.
6.5.3 DISPLAY
4-digit display provides:-
a) Continuous readout of sealing air temperature
or
b) Data on various aspects of the control system subject to use of the control
buttons and instructions on the following pages.

It is most important that the following sequence of instructions is
carried out in the CORRECT order.
If an error is made in the following sequence, e.g. if the ▲or ▼are not pressed
simultaneously, or are mis-used in any way, the Controller will move into another
non-related mode and display irrelevant data. If this occurs, STOP the sequence
IMMEDIATELY, and refer to the ‘To Correct Any Setting Errors’
instructions. (see Section 6.7)
