6.3.9 Notes on the individual press programs
For the abort speed, we recommend using a value of 300 µm/min in
the layering technique and 150 µm/min in the staining technique.
A higher value (abort speed e.g. 300 µm/min) aborts the press pro-
cedure earlier, while a lower value (abort speed e.g. 100 µm/min)
aborts the press procedure later and prolongs the press procedure.
For the all-ceramic systems from Ivoclar Vivadent (IPS e.max,
IPS Empress Esthetic), only the original standard press programs
which are especially coordinated with the materials must be used.
6.4 Other options and special features of the furnace
6.4.1 Quick selection of the firing program
Each firing program can be directly selected by its program number.
To quickly select the firing program, press the Program key and enter
the program number. Confirm with the ENTER key.
In addition, the Cursor key Left/Right or Minus/Plus keys can be used
in the stand-by screen to navigate through the firing programs.
6.4.2 Indication of invalid entry
If an invalid value is entered by means of the numeric keys (outside
the acceptable value range), the invalid entry still blinks after
confirmation.
As error message, an exclamation mark (!) blinks in the bottom line
of the parameter or detail screen until the next value is entered and
successfully confirmed or the process is aborted with ESC. The old,
valid value reappears.
6.4.3 Error message symbol
The error message symbol should supply a first indication of the type
of error:
Note, information Entry error
Information symbol Exclamation mark symbol
Technical error
Fork wrench symbol
6.3.4 Selecting the investment ring
Once the desired type of press
program has been selected, the
investment ring is selected.
The cursor position (frame around
the symbol) can be changed by
means of the Cursor keys. The
marked investment ring size can
finally be selected using the Enter key.
The ESC key can be used to change to the selection of press
programs.
6.3.5 Stand-by screen (press program)
Once the investment ring has been
selected, the stand-by screen
appears (press program).
The Program key can be used to
change to the parameter screen
(press program).
The ESC key can be used to change to the selection of the invest-
ment ring.
6.3.6 Parameter screen (press program)
The Program key can be used to
change to the parameter screen
(press program).
The ESC key can be used to return
from the parameter screen to the
stand-by screen or to the previous
screen.
The cursor position can be moved between the parameters by means
of the Cursor keys. The marked parameter can be edited with the
Minus/Plus keys or via the numeric keys and confirmed by pressing
ENTER.
6.3.7 Operation screen (press program)
The following operation screen
appears while a press program is in
the heating and holding time
phase.
During the actual press process the
following operation screen appears.
The animated arrow indicates that
the press plunger moves down-
wards. The entire time of the press
cycle is displayed once and the
path which the press plunger has
already covered since the start of
the press procedure.
6.3.8 Notes on the Ivoclar Vivadent press programs
The Programat EP 3000/G2 has been especially coordinated with the
materials systems from Ivoclar Vivadent. Therefore, the respective
parameters of the different programs have already been set ex
works. You only have to select the desired program for the
corresponding material.
