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

Overview of a cycle

The furnace will raise the table and close the muffle opening in order to start the

preheating of the table and muffle.

IF the degassing feature is chosen, the heat up ramp rate is 15 C /59 F/ min. until

degassing temperature.

The furnace will remain at each designated High Temperature until the user defines

the desired delay times 1 through 5. Possibility of up to 5 sets.

Upon the completion of the Final delay time the table will cool to ambient

Temperature and descend. Zirconia sintered work is completed.

At the end of the process, the 5 audio double-beep will be heard.

The SINTRA furnace will cool down to below 150 C.

NOTE: Different in the SINTRA PLUS.


6. Supplementary Features

6.1 The Menu Key

Supplementary features can be reached by selecting the Menu Key. This key

allows you to reach the internal menu for options and setups.

Each one of the above option can be reach by selecting the associated

"number".

Once an option I selected, follow the instruction provided in the display

screen.

6.2 SINTRA PLUS - Fast Cycle

From program numbers 200 to 249 fast cycle is available. (50 fast cycles)

These cycles implement both fast start and permit rapid opening.

These cycles start from any temperature below 300 degrees centigrade by

pressing "Start" a second time on any temperature below 300 centigrade.

In programs ranging from 200 to 249, the opening of the furnace will be automatically

at 900 C degrees centigrade the furnace will open one (1) centimeter automatically

and cool down to 800 C degrees.


In addition to the automatic opening, 3 new cooling parameters are automatically

accessible (replacing conventional cooling parameters):

OPEN definition: This is the distance of the table opening once the furnace reached

800 C degrees. The default is an opening of 7 cm from the 1cm opening (for the 900C

to 800C). The opening range can be set from 1cm to 15cm.

TIME definition: This is the time to hold at the new position. Default 1:00 min

STEP definition: This is the distance for the next distance opening default 1cm

The last two parameters will reoccur until the door is fully opened.

The fast cycles are recommended for 5-6 single units, or 2-3 bridges of 3 units.

For best result on fast cycle, raise the temperature by 50 C degrees for sintering in the

fast cycle mode.

There are two modes of running the SINTRA PLUS in Normal heat ramp or Slow

heat ramp. The default is the (normal ramp) on the SINTRA PLUS 115v.the furnace

will hold at 150 C degrees before every cycle

The active mode screen can be reached in the oven data from the Logo screen. (see

below image and instructions on accessing the screen).

The Normal Mode, the furnace is running in Full heat ramp if there is a stable

electrical supply, the furnace mode remains as Normal, and there is no need to

modify. If the contactor for any reason began to jump (clicking noise), the MODE

needs to be changed to SLOW mode.

In this mode, the first ramp until 300 C was modified to a slower ramp hence adapted

to the available electricity supply. This mode might slightly lengthen the cycle.

The default value in Sintra 11 V is (Slow) in the Sintra plus 115 is (normal) holding at

150C degrees.

How to reach the heat ramp MODE:

In Logo screen:


Checking which MODE is active:

Select "SCR" button

Select "Ent" button to open "oven data" information -
