Ivoclar Vivadent Programat CS4 - Program Structure; Settable Parameters and Possible Value Ranges

19
5.4 Program structure
The Programat CS4 basically offers two types of
programs:
a) Standard program for materials of the
Ivoclar Vivadent group (see enclosed
Program Table)
e.g. IPS e.max ZirCAD, IPS e.max CAD
b) Free programs
All the free programs are equal and available
as full-fledged programs. All the parameters
can be individually set in each program.
When the furnace is delivered ex
factory, the standard programs already
contain the recommended material
parameter settings.
The programs have been designed in such a
way that 2 predrying stages, 3 heating stages,
2 cooling stages, and 1 opening time can be set.
In case one of these stages is not
required, the time must be set to
00:00.
The predrying time includes the time of
the heating phase and is no holding
time.
5.5 Settable parameters and possible value ranges
* If the holding temperatures T2 and T3 are lower than 900 °C or 1652 °F , the maximum temperatures for the
temperature increase rates t2 and t3 are 130 °C/min or 234 °F/min.
Automatic plausibility check of the parameters
The Programat CS4 is equipped with an automatic plausibility check function.
The parameters are checked upon each program start.
In case of contradictory parameter combinations, the program stops automatically and
the respective error number is indicated.
