6.4.12 Pre-vacuum
If a firing program with pre-
vacuum is conducted, the vacuum
pump is switched on at the end of
the closing time (as soon as the
furnace head is closed). Once the
pre-vacuum time has elapsed, the
heating phase begins. Upon the
start of a program with an
individually activated pre-vacuum
(value between 1:00 and 5:00),
the V1 value is ignored. The vacuum is maintained until V2 is
reached. V2 must be higher than the stand-by temperature B.
6.4.13 Overnight program
The overnight program function can be activated for the next
program sequence in the parameter list (touch button with the
"crescent moon" symbol).
If the overnight program function has been activated, the furnace
head remains open after the firing process, the heater is switched
off, and the green START LED flashes.
No melody is played if the temperature drops below a certain level.
Once the temperature has dropped below 100 °C / 212 °F, the
furnace head closes, the heater remains switched off, and the
furnace cools to room temperature.
Advantages of the overnight program function:
In case of a power failure, the overnight program is always
continued. The program resumes at the point at which the power
failure has occurred.
6.4.14 ”Quick cooling“
If the "Open furnace head" key is pressed again with the furnace
head already completely open, the "Quick cooling" function is
started. This means that the vacuum pump is switched on for
5 minutes. This function can be stopped early by pressing STOP,
"Close furnace head", or START. This function can be activated
anytime with the furnace head open.
6.4.15 Software Update
The user should be able to conduct a software update by CD, PC,
and download 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).
A further method for updating the
software is to use the USB
memory stick. This item is
available in the Settings menu on
page 2.
To update the software, a USB
memory stick is required with a
current software image in the
form of a *.gz file. The software
version on the USB memory stick
must be newer than the one on the furnace (see Selection -
Information).
Step 1: Connect the USB memory stick with the current software
version to the furnace
Step 2: Select the menu item “Software Update”
Step 3: Select the software image file (the file name has to start
with P700/G2_)
Step 4: Start the software update with the “Open” key
Step 5: Wait until the furnace indicates a successful update
process
Step 6: Re-start the furnace
Important
Please note that the individual programs will be over-
written in the software update process. Therefore, we
recommend a data back-up (e.g. on a USB stick).
6.4.7 Help
Help text for the current screen.
6.4.8 Error message
The error group symbol should
supply a first indication of the type
of error (entry error = exclamation
mark; technical error = fork
wrench; Note = "i" symbol) with-
out the user having to consult the
Operating Instructions.
6.4.9 One-stage / two-stage programs
If the cursor is on the "one-stage program" symbol, pressing the
– / + key results in the symbol to change to the "two-stage
program" symbol. At the same time, the program was also changed
to become a "two-stage program".
If the cursor is on the "two-stage program" symbol, pressing the
– / + key results in the symbol to change to the "one-stage
program" symbol. At the same time, the program was also changed
to become a "one-stage program".
6.4.10 Program status indication
The current program status is indicated in the firing curve display:
pre-drying, closing, pre-vacuum, firing, long-term cooling, opening.
If the program is interrupted, " Pause " starts flashing as an indicator.
If a program is prematurely stopped, " Vacuum release " is flashing
while the firing chamber is flooded.
6.4.11 Pre-drying (one-stage or two-stage program)
Displaying the touch button "Pre-Drying Temperature":
Change to page 2/2 in the
"Settings" screen using the + key.
Then, select the touch button
"Preheating with the furnace head
open" and use the +/- keys to
switch on the "pre-heating"
setting.
In this way, the touch button "Pre-
drying temperature" is displayed
in the parameter list. The function
"pre-heating", however, is not yet
activated (temperature = 0).
For a program with individually
activated pre-drying, the desired
"pre-drying temperature" is set
after the program start with the
furnace head open (heating or
cooling). Once this temperature is
reached, pre-drying is carried out
during the "pre-drying holding
time" Once the holding time has
elapsed, the furnace head is
closed within the desired closing
time.
