5.2.5 Adjustable parameters in the Options menu
In addition to the parameters shown in the firing curve, several other options are available that can be activated by pressing
the [Options] button (see Chapter 5.2.3). Active options are displayed as icons in the grid next to the [Options] button.
The following firing program options are available:
Night program
If this function is active, the furnace head remains open after the firing process, the heater is switched off
and the green Start LED flashes. No acoustic signals are sounded. Once the temperature drops below
100 °C, the furnace head closes, the heater remains switched off and the furnace cools down to room
temperature.
Advantages of the night function:
After a power failure, the night program is always resumed. The program is resumed at the position, at
which the power failure occurred. After a longer power failure, the furnace head does not heat up to
stand-by temperature and the object is protected at room temperature with the furnace head closed.
If the night program function is switched on, it is active only for the next program cycle.
Setting options: On / Off
Program write-protection
If the program write-protection is activated, the program parameters and program options cannot be
changed. This is to prevent accidental changes to the program.
Setting options: On / Off
B Stand-by temperature
The stand-by temperature is the temperature to which the furnace heats up immediately after switching
on. The temperature is maintained with the furnace head closed and when no firing process is active.
Programat furnaces are programmed to a stand-by temperature of 403 °C in the factory. The temperature
can be individually set for each program.
Value range °C: 100 – 700 °C; Value range °F: 212 – 1292 °F
Two-stage program
If this function is activated, the selected program can be programmed on two temperature levels.
Setting options: On / Off
IRT mode (only available if Infrared Technology "ON")
If the IRT system is active, three different IRT modes can be selected:
– Standard: suitable for all conventional firing cycles (e.g. layering, opaquer, wash, gloss, glaze,
characterization firing, etc.) with the Programat firing tray
– Crystallization: exclusively suitable for crystallization firing cycles (e.g. IPS e.max CAD crystallization) with
the IPS e.max CAD Crystallization Tray
– Fusion: exclusively suitable for fusion firing cycles (e.g. IPS e.max CAD fusion / crystallization CAD-on)
with the IPS e.max CAD Crystallization Tray
If IRT is activated, the mode "Standard" is used as the default setting.
Setting options: Standard, crystallization, fusion
Predrying temperature Stage 1 (only available if Infrared Technology "OFF")
In a program with activated predrying in Stage 1, the desired "predrying temperature" is reached (heating
or cooling) after the start with the furnace head open. Once this temperature is reached, predrying is
conducted during the "predrying holding time". Once this time has elapsed, the furnace closes within the
desired closing time.
The predrying temperature for Stage 1 can be set as follows:
Value range °C: OFF or 100 – 700 °C; Value range °F: OFF or 212 – 1292 °F
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)
