Opening Of The Pressure Chamber - Dreve Drufomat scan Mode D'emploi

Info
For safety reasons the process of
an unwanted downwards move-
ment of the piston or an interlock
of the escapement can be stopped
by the electronics:
a) The process of moving the pis-
ton downwards is carried out too
slowly (max. 3 seconds between
action right hand and action left
hand) or
b) The two-hand control is aborted
before reaching the minimum
pressure.
In both cases there will be 5 short
acoustic warnings, the piston will
be ventilated and remove to its
original position. The display

8.5 Opening of the pressure chamber

In order to attain a complete cool down
of the thermoforming blank the valve
at the tension ring (12) is to be opened
slightly after 2/3 of the adjusted cooling
time. Through this the warm air inside
the piston will be released and replaced
by cool air due to the pressure regula-
tion of the electronics. After the cool-
ing time has elapsed there will be an
acoustic signal (indication in the display
(c) will blink).
will show the last stored values.
In order to start the thermofor-
ming process newly the process
can be repeated immediately, as
described in this chapter.
The adjusted pressure will be verified by
the electronics and regulated, if neces-
sary. The display shows the adjusted
cooling time (c) which then counts
down to 00:00.
Directly before releasing the pressure
inside the piston the ventilation valve
at the F insert (6) should be opened.
Push the push button (8) for approx.
two seconds; the pressure inside the
piston will be released. After complete
ventilation the piston will remove to its
original position. Swivel out the plate
reception (11) at the corresponding
handle (10) and remove tension ring
and thermoformed result.
The display (2) will show the last used
programme; the scanning device (1) is
ready for a new thermoforming pro-
cess.
