6.3 Firing using an individual program
Step 1:
Switch to the program selection by pressing the Home key (93).
Select Individual programs with the right cursor key. Select a free
program.
Step 2:
Press the desired parameter (e.g.
temperature increase). The input
mask appears. In the lower field,
you will find information about the
acceptable temperature range (min.
and max.). This will facilitate the
entry and prevents input errors.
Step 3:
Press the START key (73) to start
the program. The process is
indicated in the firing curve display.
6.4 Further possibilities and special features of the
furnace
6.4.1 Illogical values or incorrect entry
If an illogical value is entered by means of the numeric keys
(outside the current value range), the invalid entry still blinks after
confirmation.
As error message (entry error: entry
outside the value range), an excla-
mation mark blinks in the bottom
line until the next value is entered
and successfully confirmed or the
process is aborted with ESC. The
old, valid value reappears. Please
refer to the parameter details for the value range.
6.4.2 Program write protection
If the program write-protection is activated in the Settings, all Ivoclar
Vivadent programs are write-protected. This is indicated by a closed-
lock icon in the stand-by display and the parameter list.
Only Ivoclar Vivadent programs can be protected with the
program write-protection. This function is not available for
individual programs.
6.4.3 Stopping the running program
Press the STOP key once to pause a running program. The green LED
in the START key blinks. Press the STOP key twice to completely stop
the program or press START to continue. The current temperature is
maintained.
6.4.4 Changing the parameters while the program is running
All parameters of the program which have not yet been executed,
can be changed while the program is stopped (green LED blinks).
6.4.5 Quick opening of the furnace head
By switching the symbol “standard opening of the furnace head”
for the currently loaded program, the user may activate a ”quick
opening of the furnace head” at the end of the program.
6.4.6 Closing of the furnace head
Various functions are available for the
closing of the furnace head. If the cursor
is on the spot in the parameter list shown
in the figure, you can toggle between the
following functions by using the + or –
key:
– Thermo Shock Protection
– Pre-drying
– no function activated
– TSP – Thermo Shock Protection
The TSP function prevents the object from too high of
temperatures during the closing process. For this purpose, the TSP
function gauges the temperature of the firing chamber in the fur-
nace head upon start of the firing program. If required, the closing
path within the set closing time S is adjusted. TSP is only active if
no active predrying has been selected or if the temperature in the
firing chamber is too high when the program is started. In
addition, TSP works only if the stand-by temperature of
B = 403 °C/757 °F required for Ivoclar Vivadent materials is used.
The active TSP function is shown on the display by means of the
symbol "TSP". If programs are started with a temperature of more
than 680 °C / 1256 °F, an error message is produced.
– Pre-drying
If the pre-drying function is activated, the furnace heats to the
specified stand-by temperature.
6.4.7 Power-save mode
If the power-save mode is activated and the furnace head closed,
this function is automatically activated after 30 minutes if the fur-
nace is idle and no key is pressed during this time. The Power Saving
icon appears on the display. The power-save mode is terminated by
pressing any key.
6.4.8 Protocolling
If the protocol function is activated (see section 5.5.1), a firing
protocol can be copied to a PC at the end of the firing program by
means of the included software. Subsequently, the protocols can be
edited and managed on the PC.
The furnace saves the 15 firing programs that were last
conducted for protocolling. Copying the protocols to a PC
will automatically erase the saved entries on the furnace.
6.4.9 Software update
The user will be able to conduct a software update by PC and down-
load cable. For that purpose, the software download mode of the
furnace is activated by pressing two special keys simultaneously
while the power supply is switched on. For further details, please
refer to the Software Update Instructions
(www.ivoclarvivadent.com/downloadcenter).
Please note that the individual programs are being erased
upon a software update. We therefore recommend that
you carry out a data backup (e.g. using the Programat
PrograBase 2 PC software).
