FOCUS 4010/HT Dental Porcelain Furnace Page 15 Manual version 4.2.2013
Function
An additional heating or cooling mode. May be lower or
higher than HIGH TEMP. If higher - heating will be
reactivated. If lower - chamber will be opened slightly to
enable quick cooling to the FINAL TEMP value. Then the
platform will close the muffle and the temperature will
stabilize on FINAL DELAY temperature.
Comments
Optional parameter. In case not in use should remained blank
Limits
100C to 1100C in normal
100C to 1180C in HT
Parameter
FINAL DELAY
Function
The time duration the furnace will remain at FINAL TEMP before
opening the chamber.
Limits
0 to 30 minutes.
0 to 4:30 H in the HT Programs
Comments
To use only when FINAL TEMP parameter is programmed.
Parameter
COOL TIME
Function
The time required to lower the platform. The platform descends
in three progressive stages. Starting from when the firing
chamber is closed to the lowest position.
Limits
0 to 30 minutes.
Parameter
VAC. START [S]
Function
The temperature at which the vacuum starts
Limits
Any value within the selected temperature range of the program
(C) or (°F).
Comments
If equal to START TEMP than vacuum will start before DRY
TIME begins.
Parameter
VAC. END [E]
Function
The temperature at which the vacuum to be released
Limits
Any value within the selected temperature range of the program
(C) or (°F).
Comments
Must be lower or equal to the HIGH TEMP or FINAL TEMP (in
case FINAL TEMP defined higher than HIGH TEMP).
Function
VACUUM LEVEL [L]
Function
The level at which the vacuum is held during the cycle.
Limits
From 100 mmHg to 750 mmHg
In case constant vacuum pump activation required – the
VACUUM LEVEL set should be – 760mmHg.
Comments
Must always be set when using a vacuum firing.
Parameter
VAC. DELAY [DEL]
Function
Duration of the time for maintaining vacuum at HIGH TEMP or
FINAL TEMP (if FINAL DELAY defined).
Limits
0 to 30 minutes.
0 to 4:30 H in the HT Programs
POINTS TO NOTE
 When programming data into a parameter, check that the data is correct and that it
correlates with the other parameters.
 Remember that parameters have limits, if you enter data above or below these limits
the data will not be entered.
 In the event of an error, the warning tone will sound by pressing START and the
firing cycle will not start. The erroneous parameter will blink indicating the source of
the problem. This parameter isn’t logical or it is out of the permitted limits.
