26 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. 26 P a g e

27 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. 27 P a g e

28 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: 28 P a g e

29 Checking which MODE is active: Select "SCR" button Select "Ent" button to open "oven data" information - Following the HZ number you will see slow (S) or normal (N) How to change of Mode: Go back to Logo screen, by selecting the "SCR" button. Selected again the "SCR" button to access the Diagnostic Menu. Press button "4" on keyboard to select: "Elevator time setting" Then press either button "4" or "5". "4" is normal or "5" slow. See below image. 29 P a g e

30 Following the change go back to "oven data" and check that the change appear on the right side of the screen. Example (S). Note that the furnace in normal mode at 115 V will stand by at 150 degrees centigrade to avoid a burning of the heating fuse!!! Warning!!! 1-Do not use any tray for fast cooling cycle Place the work directly on the base of the sintering refractory table Fast cooling will cause the tray to crack. 2- Do not place the tray on a cold ceramic or metallic surface, the tray can be removed from the firing table only once completely cold. 6.3 Accessories 2 Sintering trays 2 Sintering cover 100 gr firing beads 30 P a g e
