FEATURES OF THE ELECTRONIC CARD
The machine has 9 selectable programs. Programmes P1÷P8 are composed by 4 modifiable variables.
Programme P9 "External Vacuum" is composed by 2 modifiable variables only (Vacuum and Extra-Vacuum).
Start it by pressing the Stop button (8).
Variable
1) VACUUM
2) EXTRAVACUUM
3) GAS
4) SEALING
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 40%
Residual vacuum (99-40)= 59%
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).
