before turning on the plug in the net contact
check if the voltage in the electrical network
correspond to the working tension. In case of
discrepancy, consult a specialist;
on no account do not alter the device;
the notices and stickers must be kept in good
condition so that they are easily readable; they
should not be removed!
the machine must not function in case of being
damaged and in position to injure the staff or a
third person;
keep the cables out of heat, oil and coarse
objects; do not catch the device by the cable
when you move it.
switch off the furnace and pull out the plug of
the feeder cable from the contact before each
cleaning or upkeep.

PARAMETERS AND PROGRAMMING
In order to change the value of a parameter it is
necessary to do the following steps:
There are two possible ways of leaving the programming
mode after you have finished with the changes in the
parameters’ value:
FIRST EXIT:
SECOND EXIT:
With the multi functional rotary knob MFKchose the
program which parameters you want to change;
Press button PROG. Indicator of the button RUN
begins to blink green/red and you can see on the
display:
XXX : YYYYYYYYYY SEE
PROGRAM NAME
The letter expressions means:
ХХX - number of program;
YYYYYYYYYY - name of program;
SEE - view data;
PROGRAM NAMЕ- parameter which to be
changed.
PROGRAM NAMЕis the first parameter which is
shown when you enter in PROGRAM mode. Turn
left/right the MFKin order to chose the parameter
you want to change;
Press button RUN in order to chose the value of the
parameter you want to change. If you have chosen
the first parameter you would see on the display:
XXX : YYYYYYYYYY SET
PROGRAM NAME
Indicator of the button RUN turns off and the red
indicator on the button STOP begins to blink.
Turn the MFRK to change the parameter value.
Press button STOP in order to leave the programming of
the current parameter. Indicator of the button RUN starts
to blink again in green/red which means that it is possible
to program the next parameter.
press button ESC. This will CANCEL all the changes that
are made in the parameters’ value in the program.
press button PROG. This will SAVE all the changes that
are made in the parameters’ value permanent.
The indicator of button RUN will flash in green in working
mode if the temperature defined by the parameter IDLE
TEMP is reached and if the temperature is not
reached it will flash in red.

HINTS
The content of each program can be viewed during the
performance. For this purpose the MFKshould be
turned.
The parameter values are displayed in series and stay on
the display for 3 seconds. However, if during this time the
button is pressed, the values are displayed while this
button is pressed.
Values of the parameters FIRE RATE, FIRE TEMP и FIRE
TIME can be changed during the execution of the
program. This can be done with the buttons PROG, ESC
and and with the turning of the multifunctional knob
MFK.
By pressing the button PROG during program execution,
display shows the value of the parameter FIRE RATE and
by MFKthe programmed value can be changed.
If you do not respond within the next three seconds, the
display shows the current stage of program execution.
In the same way, by pressing the ESC key can be changed
parameter FIRE TEMP, and by button you can change
the parameter FIRE TIME.
When programming the temperature conditions for
parameters IDLE TEMP, DRY TEMP and FIRE TEMP the
program temperature cannot be lower than this of the
previous parameter and at the same time higher than
this of the next parameter.
There is a possibility for fast changing of parameters
which have TEMPERATURE and TIME dimensions. When
you push the button and rotate the MFRK the value
will change by 100 points, and by pushing and rotate
the MFRK the value will change by 10 points.

7. IMPORTANT PRACTICAL INFORMATION
1. Avoid positioning of furnace and pump in the
immediate vicinity of heat sources (radiators).
2. Install the vacuum pump in a well-ventilated
locations. Ensure that the apertures in the frame plate
are free and that no foreign object can fall into the
furnace base.
3. Avoid placing any objects on the frame plate, place
only on the face cooling plate.
4. Ensure that the sealing ring in the furnace head and
the sealing rim of the furnace base are kept clean and
undamaged.
5. Close the chamber between working cycles, but not
tightly, and leave a distance of approximately 1 cm.
6. It is strongly recommended to use porous ceramic tray
(on request - № 81022).
WARNING! For precise operation of the device is
necessary tempering oven for half an hour before the
first use of the day. To do this after turning on the
furnace, run at least one program with an empty camera
and wait another 20 minutes.
7. If the power supply is interrupted during the working
process and:
a. If the temperature in the chamber has not
decreased by more than 15 degrees, the current
program will continue from the stage at which it
has been stopped.
b. If the temperature in the chamber has decreased
by more than 15 degrees, the following message
will appear on the display:
LONG TIME POWER OFF
In this case the program cannot continue. You have to
press the button STOP in order to exit this state.
The total number of the programs is 203 - with numbers
from 0 to 202. Programs from №1 to №18 have
parameters for ceramic NORITAKE. The manufacturer has
entered same parameters in all other programs.
The program №201 is devoted for calibration of the
furnace by means of a silver test.
The program №202 is designed for auto calibration using
the optional calibration kit.
It is responsibility of the customer to enter the data for
the ceramic that he uses before he starts working.

9. AUTOCALIBRATION
ATTENTION:
The furnace is optionally provided with a kit for
autocalibration, which is a ceramic table fitted with special
holders. A wire of pure silver 9999 is attached on them.
These holders are connected by wires to the other side of
which a special connector is mounted.
The auto calibration kit is put in place on the tray. The
connector is plugged in the socket labeled ACAL. This
socket is located at the rear side of the furnace.
After plugging on the upper left corner of the display the
sign * appears.
Start program 202. After about 2 hours the program ends.
If during the execution of the program there was a problem
and the silver wire is disconnected, when calculating
coefficient was outside the normal range, the display
shows:
Err: Bad value = KKKKK
TTTTT RRR AAAAA,
Where
ККККК is the wanted coefficient
ТТТТ.Т is the temperature at break
RR.R is the ambient temperature
ААААА is the value measured by ADC
( the normal range of the coefficient is between 10000 and
12000)
If during the execution of the program there was no
problem and autocalibration has proceeded normally, the
display shows:
Old = OOOOO New = KKKKK
TTTTT RRR AAAAA,
Where
OOOOO is the old coefficient
KKKKK is the new coefficient
ТТТТ.Т is the temperature at break
RR.R is the ambient temperature
The furnace beeps at the end of the program.
Perform the following actions:
Take out the plug from the socket ACAL;
Remove the auto calibration kit;
Place the working ceramic tray again.
Press the STOP button;
Once you press the STOP button, the furnace is restarted
and is ready for operation.
This accessory is sold separately.
