5. Operation and Configuration
Predrying holding time Stage 1 (only available if Infrared Technology "OFF")
This parameter defines the duration of the predrying process for Stage 1 once the desired predrying
temperature has been reached.
Value range Off or 00:00 – 60:00 (mm:ss)
Predrying temperature Stage 2 (only available if Infrared Technology "OFF")
Pre-drying for Stage 2 is only available if Stage 1 has also been activated. The parameters are set in the
same way. At this stage, the furnace head is half open.
Value range °C: Off or 100 – 700 °C; Value range °F: Off or 212 – 1292 °F
Pre-drying holding time Stage 2 (only available if Infrared Technology "OFF")
This parameter defines the duration of the predrying process for Stage 1 once the desired predrying
temperature has been reached.
Value range Off or 00:00 – 60:00 (mm:ss)
Thermo Shock Protection (TSP) (only available if Infrared Technology "OFF")
The TSP function protects the dental-lab work during the closing process. For this purpose, TSP gauges the
temperature of the firing chamber in the furnace head upon the start of the firing program. If required,
the closing path within the set closing time S is adjusted.
Setting option: On/Off
Pre-vacuum
If a firing program is conducted with pre-vacuum, the vacuum pump is switched on at the end of the
closing time (as soon as the furnace head is closed) and run until the pre-vacuum time has elapsed. The
heating phase begins after the pre-vacuum time is over.
The value V1 is ignored upon the start of a program with individually activated pre-vacuum. The vacuum
remains switched on until V2 is reached. V2 must be higher than the stand-by temperature B.
Setting option: Off or 01:00 – 05:00 (mm:ss)
Hv Vacuum holding time
With this function, the vacuum share of the holding time can be individually set.
Example: H (holding time) = 02:00 (mm:ss). If a vacuum share of 50% is desired, the parameter "Vacuum
holding time (Hv)" has to be set to 01:00 (mm:ss).
Setting option: Off or 00:01-60:00 (mm:ss)
Quick opening of the furnace head
If the option "quick opening of the furnace head" is activated, the furnace head opens at maximum speed
at the end of the holding time.
Setting option: On/Off
Extraction system
If this function is activated, vapours are extracted by means of the vacuum pump during the closing
process or fresh air is suctioned in for better burning and drying.
Setting option: On/Off
Vacuum quality
The vacuum pump is switched off as soon as the set vacuum quality VG1, VG2 or VG3 in per cent:
25 / 50 / 75 / 100 has been reached. VG2 is only available if the second or third heating stage has been
activated. VG3 is only available if the third heating stage has been activated.
Setting option: 25 / 50 / 75 / 100 percent
