5 Adjusting the firing chamber temperature
The VITA - VACUMAT 500 furnace is supplied with a digitally controlled potentiometer for automatic
adjustment of the firing chamber temperature. The factory-set temperature test circuit is adjusted as follows:
At 1000°C a voltage of 9.25 millivolt may be measured at the built-in thermocouple (PtRhPt). Should the
measurements differ during the life of the furnace, the adjustment may be checked and corrected using the
supplied program.
The adjustment program is selected as follows:
1. Select program No: 294 and press the "#"-Key
The program displays the following settings:
Pre-drying temperature: 600°C
Pre-drying time: 6:00 min
Heating-up time: 66°C / min
Final temperature: 1000°C
Hold-time for final temperature: 5:00 min
2. press the "Start"-Key
The program starts, parameters may not be changed, the program must be stopped by pressing the "Stop"
Key.
The LCD-Display in Block A indicates the temperature of the firing chamber in °C (degrees Celsius).
The LCD-Display in Block B indicates the value in millivolt.
After two minutes in the hold-phase at a temperature of 1000°C, a short signal sounds which indicates the lift-
keys "UP / DOWN" may now be used for adjustment. Using the "UP / DOWN" keys (UP = Increase, DOWN =
Decrease), the voltage value may now be adjusted to 9.25 millivolt. At a temperature range of 1000°C a
change of 0.01 millivolt causes a change in the firing chamber temperature of 1°C.
6 Protection against Power failure
The VITA VACUMAT 500 is protected against power failure. This backup device is activated immediately in
the event of a mains power failure during a firing or stand-by program. If the power failure lasts for less than
20 seconds the program continues. In case of power failure for more than 20 seconds the program is aborted
and the following is displayed:
The LCD-Display of Block B indicates the phase where the program aborted:
Phase 1 = Pre-drying phase
Phase 2 = Heating-up phase
Phase 3 = Hold-temperature phase
Phase 4 = Cooling phase
Pressing of the "STOP"-key deletes all messages and the furnace is once more ready for use.
Notice: In case of the mains power supply in the laboratory being turned off accidentally with the furnace in
operation or on stand-by, the same symptoms as those of a power failure will be indicated after the
power resumes.

Err M Should the lift not have reached ist upperor lower within a certain time, the error message „errM“
will appear in flash mode in the temperature indicator °C. At the same time, this monitors the
microswitches for the upper lift positions.
The error message „errM“ will also appear if the microswitch contact is defect. To delete the error
message „errM“, press „STOP“ key. The time lapse until this error message appears can be set
using programm 901 and key #. The time value can be selected in the range 10 - 20 seconds; the
factory stored value is 15 seconds. The time selected must be longer than the time the lift drie takes
to move from the lower to the upper position. If the time is too short, the motor will switch off too
early and the lift will be unable to reach ist nd position. In case of incorrect input of program
parameters, a short signal indicates the error and the last valid input is assumed. In order to
recognize the reliable closing contact of the mocroswitches, the debounce-time is set via program
no. 902 and key #. The range for the setting is 2 - 10 ( number x 15 msec. = debounce time ). The
factory-set value is 3. This setting should not be altered.
In case of incorrect input of program parameters, a short signal indicates the error and the last valid input is
assumed.
In case of recurring "Err"-Messages after Power OFF/ON, please contact the VACUMAT service Department
of your local VITA distributor.
10 Additional service advice
Daily usage of the VITA VACUMAT 500 is highly demanding. Due to external influence, such as very fine
dust, the lift drive system needs to be cleaned regularly with a dry cloth.
The following problems/changes may be solved using the supplied utilities:

Alloys with a thermal expansion coefficient ≥14.5 x 10-6 x K-1should be fired using slow cooling from the 1st
dentine firing onwards. Slow cooling from firing temperature to starting temperature should take no less than
5 minutes. This increases the leucite content in the metal ceramic and raises the thermal expansion
coefficient of the ceramic.
The vacuum time, indicated in the "VAC" column by an "X", resuluts automatically from the given temperature
rise °C/min. The vacuum switches on at the biginning of the temperature rise and switches off again when the
end temperature is reached.
