Sensor controlled vacuum
This key is used to select/display the
vacuum percentage, from 0 to 99%. The
key LED turns on while the operator selects
the vacuum percentage and during the
performance of the vacuuming stage.
Additional vacuum (Time)
This key serves to select/display the extra
vacuum time, from 0 to 99 seconds. To use
this option, it is necessary to previously
program a 99% vacuum. The key LED turns
on while the operator selects the extra
vacuum time and during the performance
of this process.
Gasflush
(Top key)
This key allows displaying the vacuum
percentage left in the chamber when gas
has flushed in. Selecting
percentage, between 99 and 0, is done by
pressing the decrementing
example, if 20% of gas should flush in,
press the decrementing key until the
reading is 79. The key LED turns on while
the operator selects the percentage of
vacuum left and during the gas flushing
process.
Gas Switch
(Bottom key)
It activates/deactivates the gas option. If
the key LED turns on when the key is
depressed, the option is activated. If on
pressing the key again, the LED turns off,
the gas flushing option is deactivated.
Sealing
This key is meant to select/display the
sealing time, from 0 to 7 seconds. The key
LED turns on while the operator selects the
sealing time and during the sealing
operation.
Soft air Inlet
This is to select/display the soft air inlet
time, from 0 to 99 seconds. The key LED
turns on while the operator selects this
time and during the execution of this
function.
Program
This key gives access to the programme
selection.
Cycle Stop
It allows interrupting the cycle and going
over to the next stage. Pressing the key
several times results in activating the air
inlet.
Programming the functions
the gas The electronic unit allows to store 10
different programmes. Programme 0 is
key. For fixed and cannot be changed. Its values are
as follows:
Vacuum: 99 %
Sealing: 3 s
The cover should be OPEN, as an ESSENTIAL
REQUIREMENT
programming steps are described below,
taking a possible programme as an
example:
PROGRAMME 4
Vacuum: 99 %
Sealing: 3,5 s
1.Press the Prog key: its built-in LED turns
on. Press the Incrementer or Decrementer
key until display #1 shows value 4.
2. Press the Vacuum % key. The LED of this
key and the % LED of display #2 turn on,
showing that the vacuum percentage is
being programmed.
Then, press the incrementer key till 99 is
displayed, which corresponds to the
selected vacuum percentage.
3. Press the Additional Vacuum key. The key
built-in LED and the "Seg" LED of display
#2 turn on. Press either the Incrementer or
Decrementer
99+: 0 seg Gas: 0 %
Soft air: 0 s
for programming. The
99+: 6 seg Gas: 20 %
Softair: 8 s
key until value 6
corresponding to the duration, in seconds,
of the extra vacuum operation is shown on
display #2.
4. Press the Gasflush key (Top). The built-in
LED and the % LED of display #2 turn on.
With the Incrementer or Decrementer key,
make value 79 appear in display #2, as it
corresponds to the vacuum percentage to
be left in the chamber, once gas (20%) has
flushed in.
5.Press the Gas Switch key (Bottom). If the
LED is on, this means that the option is
already activated. By pressing the key
again, the LED turns off and the option is
temporarily deactivated. In this event,
although there is a percentage of gas
programmed, no gas would flow into the
chamber, until the function is reactivated.
6.Press the Sealing key. The LED of the key
and the "Seg" LED of display #2 turn on.
Using the Incrementer or Decrementer key,
have value 3.5 being the duration in
seconds of bag sealing, displayed in
display #2.
7.Press the Soft Air key. The built-in LED and
the "Seg" LED of display #2 turn on. With
the Incrementer or Decrementer key have
value 8, being the duration in seconds of
soft air inlet into the chamber, displayed in
display #2.
8.In order to change any of the entered
values at any time, it is as simple as to
press the relevant function key and to
select the new value with the Incrementer
or Decrementer key.
9.Close the cover immediately after having
selected all the values of the programme.
The programme is stored automatically.
Warning: The last described operation is
essential to have the programme stored in
the microprocessor memory.
On closing the cover, the working cycle starts
automatically. As the cycle is carried out, the
key built-in LEDs successively turn on,
showing the stage of the cycle in progress.
BAG CUTTING
The bars including bag cutting threads are
supplied as an optional kit. To install them,
the sealing bar must be replaced by the new
bar provided with the cutting thread and one
of the wires in the sealing transformer must
be changed to the power indicated on the
electric layout:
- V-402 /V-421 /V-426: 15V (20V depending
on the bag type).
- V-641: 15V (short bar), 23V (long bar)
- V-821: 20V (short bar), 30V (long bar)
For the bag cutting operation, it is enough to
programme the suitable sealing time in the
