6. Practical Use
The operating procedure for the Programat P300/G2 will be
explained with the help of two examples: one Ivoclar Vivadent and
one individual program.
6.1 Switching on/off
Put ON/OFF switch (11) on position “I”. The furnace conducts an
automatic self-test, which will be indicated in the beginning.
Subsequently, a status bar shows that the self-test is being
conducted. Make sure that the furnace is not manipulated during
this time.
6.1.1 Stand-by mode
The stand-by display is shown after the successful self-test and the
program selection (see section 4.5).
A program can be selected by
pressing the + or - key or by
entering the required program
number using the numeric keys.
The parameter list is displayed by
pressing the P key.
6.1.2 List of parameters
The list shows all the parameters.
One-stage program
If a two-stage program is used, the parameters are displayed for the
first and the second stage in a separate screen. The P key is used to
switch back and forth between the two screens. Please note the
appropriate symbol (first or second stage).
Two-stage program
stage 1 is shown stage 2 is shown
If the cursor is on the symbol for the program stage, you can toggle
between a one- and a two-stage program by means of the + or –
key.
Starting a program is possible at any time, even if the input screen
for the second stage is still being displayed.
Special variant: Conducting a one-stage program in which only part
of the holding time is fired with a vacuum (requirement: holding
temperature 1 = holding temperature 2).
6.1.3 Operating indicator: Firing curve
If the program is started with the START key, the firing curve display
with the vacuum status is shown.
The following information is always displayed:
a) Program number and program group
b) Remaining time
c) Current temperature
d) Status of vacuum
e) Status bar
If a two-stage program is selected,
two stages are shown.
The remaining time can be
displayed or the parameter list
accessed for information purposes
at any time during a firing cycle by
pressing the P key. The parameters
can be modified only if the program
is stopped or in the stand-by mode.
6.1.4 Operating indicator: Remaining time
If the P key is pressed while the
firing curve is being displayed, the
remaining time will be shown.
The remaining time indicator
informs the user about the time
that is left until the process is com-
pleted even from a distance. The
remaining time is displayed in the centre of the screen in large
characters.
6.2 Firing using an Ivoclar Vivadent program
Step 1:
Select the desired program (1 to 50) according to the firing table
(Chapter 10).
Step 2:
Open the furnace head with the “Open furnace head” key (90) and
place the object on the firing tray in the furnace.
Step 3:
Press the START key (73) to start
the program. The green Start LED
starts flashing. The process is
indicated in the firing curve display.
