ON position, the furnace is now in the Stand -by Mode.
By pressing the ON/OFF button on the front panel, the furnace is turned on.
This mode is called the Idle Mode. The temperature will not rise and will
remain in STAND –BY mode. The logo of the SINTRA/SINTRA PLUS is
displayed.
3.2 Set-Up possibilities:
In order to enter the Diagnostic mode you have to turn the furnace OFF from
the front panel by pressing the ON/OFF key. Now the furnace is in the "SCR"
status.
3.3 Idle Mode:
Press the [ON/OFF] key located on the front panel, the furnace is now ready
for Program selection.
POINTS TO NOTE
It is very important that you keep the firing chamber closed in the idle mode to
prevent moisture from entering the muffle.

4. The Firing Cycle
4.1 Starting the Firing Cycle
A short press (audio single beep) to lower the platform. The firing
cycle will not start until the platform is completely lowered.
A long press (audio double beep) is heard when platform rises. Place
sintering crucible with restorations on the ceramic firing table.
Select a program number + Enter.
Press the [START] key.
The firing cycle will automatically start when the firing chamber
temperature reaches the temperature selected for the default START TEMP
(60 C /140 F). The relevant function will be shown on the screen. You
can see the graph of your cycle by pressing "SCR" simultaneously with the
cycle progression, showing the actual status of the cycle.
When the firing cycle has finished and the platform is in the lowest
position the double tone sound will be heard. The platform can be open
manually only below 450 C/ 840 F within cycle by pressing the stop
button –Normal opening will occur at 150 degrees. This safeguards the
life of the heating elements and assures that the muffle provides constant
temperature uniformity. (Different for the SINTRA PLUS cycle)
4.2 Canceling a Cycle
Should you wish to cancel the program in the middle of a firing cycle, press
the [STOP/LIFT] key. The platform is lowered and the furnace remains in the
selected program mode. The platform will open only below 450 C/ 840 F
degrees.
