Drufomat scan
8. Operation
Turn the unit on by means of the main
switch (33) at the back of the unit. By
this, the scanner (1) at the bottom and
the display (2) at the front of the unit
will be activated. An acoustic signal
shows that the unit is ready for opera-
tion; the display will show the name of
the machine Drufomat scan.
8.1 Scan modus
Every outer package of Dreve thermo-
forming blanks is labelled with a bar-
code label.
This barcode contains the encrypted
product name, material strength as
well as the individual heating and cool-
ing times.
In order to scan the material data with
the Drufomat scan, the barcode is to
be placed centrally and evenly under
the scan field (1).

There will be an acoustic signal for
the confirmation of the data capture
and the display will show all neces-
sary data.
Info
The light emanating from the
scanner is harmless. Even in case
of direct eye contact it has no neg-
ative impact!
After 15 min. without use the
scanner turns off automatically.
By pressing any key it can be re-
activated again.
During an active thermoforming
process the scanner is deactivated.
After termination of the process
it will be re-activated automati-
cally.

The minimum operating pressure
is 29 psi (2 bars). If a thermoform-
ing process is interrupted before
having reached the 29 psi (2 bar)
mark (indication of bar chart (g)
in the display), the piston will be
ventilated and will return to its
original position.
