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. 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 and the heater is switched
off. 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
Predrying temperature Stage 1
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 con-
ducted 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
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
Predrying 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
