FEATURES OF THE ELECTRONIC CARD
The machine has 9 selectable programs.
Each program is made of 4 changeable variables:
Variable Field
1. Vacuum 0 ÷ 99,9
2. Extra vacuum 0 ÷ 30
3. Gas 0 ÷ 99
4. Welding 0 ÷ 4
All packaging machines are tested at works.
The parameters set at works generally prove to be fit for use.
PHASE 1 = START-UP
Switch 1 the main switch (1). As soon as the board has been switched on, display will show the software version, then the
last program being executed (P1÷P9).
PHASE 2 = PROGRAMS SELECTION
To select the program number, just press the buttons (6) and (7).
PHASE 3 = VARIABLES PROGRAMMING
Press button (4) to enter scheduling of the program shown at the moment. By pressing again button (4), all parameters fo
the selected program will appear one after the other. Push buttons (6) and (7) to increase or decrease the value of the
parameter shown. Parameters are stored when, while running a program, the number of the program itself will appear on
the display.
1) VACUUM
It is possible to set a value from 0 to 99,9%.
The recommended vacuum percentage is 99,9%.
Scheduling of vacuum parameter is signalled through LED (9).
2) EXTRAVACUUM
You enter scheduling of such a parameter when going beyond value 99,9%. Extra vacuum parameter is shown on the
display through letter "E"; its value is included between 0 and 30 seconds. During this time the pump keeps on extracting air
from the hood after the machine has reached the adjusted vacuum level. This function is useful especially when packing
porous products as it si quite difficult to extract air from them (for example: meat).
3) GAS
It is possible to set a value from 0 to 99,9%. Such a parameter cannot be higher than the vacuum one, otherwise you will
obtain an opposite function. Scheduling of gas parameter is signalled through LED (10). If the gas LED (10) is flashing, it
means the gas cylinder is not properly connected and machine will not start. Connect it properly.
N.B.: When scheduling a program "vac + gas", the minimum residual vacuum percentage soon after gas immission should
be higher than 50%
Example: VAC 99%
GAS 49%
Residual vacuum (99-49)= 50%
4) SEALING
It is possible to set a value from 0 to 4 seconds. For the first working cycles it is recommendable to set a sealing time of
about 2,5 seconds and then lower it to prevent the teflon tape from burning. Scheduling of sealing time parameter is
adjusted through LED (11).
PHASE 4 = EXECUTION
Place the pouch inside the hood and on the sealing bar in a way as linear as possible. Try to prevent the pouch from
wrinkling. Wrinkles might negatively affect the hermetic seal formed by sealing.
Pouches shall be at least 2 cm beyond the sealing bar.
Lower the upper plexiglas cover.
The machine will start executing its working cycles.
After every working cycle, on the display will appear a number showing the total cycles being executed.
All set-up parameters are stored until they are modified.
N.B.: if you press the STOP button (8), the machine will immediately stop sucking and automatically start sealing the pouch.
This function will be used to pack liquid and hot products which may start boiling during the vacuum cycle.
