5.5.2.3 Save the firing program / firing group on the USB
memory stick
The majority of USB memory
sticks can be used as program
memory. In order to use the USB
memory stick as external pro-
gram memory, it has to be first
prepared as a storage medium.
For this purpose, connect the
USB memory stick to the fur-
nace. Subsequently, select
“Prepare USB memory stick as
external program memory” in the program manager. Select /Hard
Disk…/ and start the procedure with Open. The process is completed
when the message for the successful preparation of the USB memory
stick is shown on the display.
All the existing firing programs
(internal memory) of the furnace
can be saved on a prepared
memory stick. Select Selection –
Program manager – Copy
programs and make a choice
using the +/- keys:
• All programs
• Program (copy a single
program)
• Group (copy a single group)
After a USB memory stick is
ready for use, the selection
menu for “Select program
memory” is shown instead of
“Program groups” by pressing
the Home key.
5.5.3 Information
The information pages 1 to 4
provide information on the
current software version,
operating hours, calibration
settings and status of the
identified USB devices, such as
printer and USB memory stick.
The information display also
serves to check whether the
Programat furnace has identified
a USB device.
5.5.4 Calibration
By pressing the "Start calibration
program" touch button, the
program is automatically started.
Please see the notes in
Chapter 7.4.
5.5.5 Special programs
Press the "cogwheel" key,
followed by the touch button
"Special programs".
5.5.5.1 Vacuum pump test program
With this program, the vacuum
performance of the furnace
vacuum system can be auto-
matically tested. For that
purpose, the achieved
(minimum) pressure in mbar is
measured and indicated. If the
pressure value is below 80 mbar
(hPa), the vacuum performance
of the system is adequate.
5.5.5.2 Heater test
The quality of the heating muffle
may be automatically checked by
means of the heater test (durati-
on: approximately 7 minutes).
The heater test should only be
conducted with the empty firing
chamber, since an object in the
chamber (e.g. firing tray) may
influence the test result. Conduct
the heater test immediately after
switching on the furnace and before any actual firing procedures. If
the furnace is too hot, an incorrect heating muffle quality will be
indicated. If the heating element quality falls below 50 %, replacing
the heating element is recommended.
5.5.5.3 Cleaning program
The cleaning program is used to "clean" the heating muffle
(duration: approximately 17 minutes). After a cleaning program, it is
recommended to calibrate the furnace. In case of problems with
discolouration of the ceramic, we recommend replacing the firing
table or the firing tray material.
