Program P192
Cleaning program for the heating muffle.
These parameters may be changed, if
required. The write protection is activated
for the default settings. This cleaning
program also offers the possibility to
maintain the vacuum during cooling. For
that purpose, V
2
> T and L >= 50 and L < T.
Program P93
Vacuum pump test program.
With this test program, the performance
of the vacuum system of the Programat
P200 can be tested. The (minimum) pressure
reached is indicated in mbar. If the value
reached is below 50 mbar, the vacuum
performance is excellent. If the value is
clearly higher (e.g. above 80 mbar), refer to
Chapter 8.2.
The test program is started by selecting
Program P193 and pressing START. The
program can be stopped by pressing STOP.
The maximum duration of the test is
5 minutes. After reaching a pressure of
40 mbar, the evacuation procedure
continues for another 2 minutes. After
5 minutes, the flooding process begins
automatically. The display shows that last
mbar value.
To leave this program, enter the desired new
program number and confirm with ENTER
(the cursor is not activated).
Program P194
Settings for printing a firing protocol via the
PC connection (17)=(RS232). If this program
is activated, the firing protocol is printed
once the firing program is completed.
Parameters to be set with the ‘+’/’–‘ keys:
T: Information about the kind of device
connected to the interface – PC or printer.
0 = protocol
1 = printer
2 = PC *
* Data format for Prograsoft (www.ivoclarvivadent.com)
The language is selected in field L.
D … German
E … English
I … Italian
S … Spanish
F … French
(P) … Portuguese
All other fields are blank.
Transfer parameters of the interface:
The data transfer parameters of the interface
are preset and cannot be changed:
(Connection see Chapter 4.3)
Baud Rate: 9600
Data bits: 8
Parity: none
Stop bits: 1
NOTE
These parameters also need to be set for the
printer or the PC in order to ensure optimum
data transfer.
Program P195
The pre-vacuum time can be set in the
parameter field H in the range of 01:00 to
05:00 minutes in one-minute increments
using the [–] and [+] keys. All other fields are
blank.
Program P196
Special program for Service Technicians and
to lock the entire furnace. By entering a
three-digit code in field L, all the firing
programs of the furnace are protected from
unauthorized access. The procedure to lock
and unlock the furnace is as follows:
Locking the furnace:
1) Select parameter field L.
2) Enter a three-digit code and confirm
with ENTER (the write protection symbol
is shown)
3) Repeat the same three-digit code and
confirm with ENTER (the write protection
symbol is activated, i.e. a check is shown).
Now, none of the firing programs
P1 to 189 may be changed. The
settings of the auxiliary programs
may be changed even if the lock
is activated.
Should you forget the code, only
an Ivoclar Vivadent Service Center
is able to unlock the furnace.
Unlocking the furnace:
1) Select parameter field L
2) Enter the correct three-digit code and
confirm with ENTER (the write protection
symbol and the check are blanked)
Now the programs may be changed, except
the ones for which write protection has been
specifically activated.
Program P197
This program is used to change from
Celsius mode (°C) to Fahrenheit mode (°F).
When entering P197, the mode is changed
automatically.
Program P198
Display of software version, number of
operating hours and firing hours:
– The current software version is indicated
in holding temperature T field (72),
e.g. 60 = version 6.0.
– The number of operating hours is
indicated in the remaining time field (70)
– The number of firing hours is indicated in
the input field (76).
– The number of vacuum pump hours is
indicated in the V
1
input field (78)
Program P199
'Silver Test'
With the ‘+’/’–‘ keys, the temperature in the
firing chamber can be recalibrated. The value
is indicated in the input field (79).
6.4 Programming /
changing the program
– Program cards are available for noting
the program data.
– As long as no program is running, data
may be entered or modified as follows:
• Select the parameter with the arrow key
• Enter the value and confirm with ENTER.
– Important for the input of V2
(vacuum off)
– Firing with vacuum off during holding
time H, enter V
2
as follows:
Celsius mode: V
2
= T – 1 °C
(e.g. T = 1050 °C, V
2
= 1049 °C)
Fahrenheit mode: V
2
= T – 2 °F
(e.g. T = 1922 °F, V
2
= 1920 °F)
(Vacuum is switched off at the start of the
holding time H)
– Firing with vacuum on during holding
time H, enter V
2
as follows:
V2 = T (e.g. T = 1050 C, V2 = 1050 °C
or T = 1922 °F, V2 = 1922 °F)
(Vacuum is not switched off until the end
of the holding time H)
– If 32 °F is set for V
2
and confirmed with
ENTER, V
2
is automatically O. O means
firing without V
2
. The same is valid for
the L and V
1
parameters.
– Once the program has been
completed, the program is
automatically stored.
– In standard programs (P3–P10), the values
can altered once the write protection has
been deactivated.
– Changeover from one program to
another:
The program cannot be changed while it
is in progress (green LED in the START key
is illuminated).
• Press STOP twice
• Select the parameter ‘Program Number’
with the arrow keys and enter the new
program number
• Confirm with ENTER
• Press START
– Changing the preselected data while a
program is in progress is only possible
if the actual temperature has not yet
reached the set T value (if it is too late to
change the parameter, the value is not
accepted):
