5.4 Program structure
The furnace offers three types of programs:
a. Standard programs for Ivoclar Vivadent materials
b. Free programs
c. Test programs
a) Standard programs for Ivoclar Vivadent
materials (see chapter 10.1)
– IPS e.max CAD
– IPS Empress CAD
b) Free programs
All free programs are available as equivalent
and thus fully-fledged programs. All the
parameters can be individually set for each
program.
When the furnace is delivered ex
works, the standard programs already
contain the recommended material
parameter settings.
However, the parameters can be changed and
overwritten at any time, if required, if the
programs are to be used for other purposes.
Therefore, the 50 programs are also available as
free programs.
The programs are designed in such a way that
they can be either used as conventional, one-stage
programs or as two-stage programs, if required.
The mode can be changed via the symbol (one- or
two-stage program) by using the + or – key.
c) Test programs
Various test programs are available. Please refer
to chapter 5.5 Settings / configuration and
information.

Automatic plausibility check
The furnace is equipped with an automatic plausibility check function. The parameters
(e.g. T 960 but L 1000) are checked upon each program start. In case of contradictory
parameter combinations, the program stops automatically and the respective error
number is indicated.
Examples of firings
– Typical glaze firing
– Typical crystallization firing
