1 ELEKTRON VACUUM FURNACE TECHNICAL DETAILS: MODEL: VA-1 DIAMETER: Ø90 mm HEIGHT: 50 mm POWER: 1 KW VOLTAGE: 220 V TEMPERATURE: 1150 C Description: The construction of furnace is made of shape steel plate. With adequate mechanism, the working plate is rising and downing wherewith the product is inserting and removing from furnace. Burning process in chamber running with adequate pressure of vacuum or without vacuum. The insulation area of furnace is composed by high quality ceramic fibers strata based on aluminum oxide and circulation air, thus heat losses are on minimum. The heaters are made by doped electro-resistant wire kanthal A1. Furnace is dyed with electrostatic sediment and fried in chamber.

2 The view from the back of the oven 1. The switch to turn on furnace volt power supply apparatus 3. Power vacuum pump 4. Fuse 5. Connection to vacuum pump Note: If the stove is cold (first turn) leave it to warm up 10 minutes or let a process with no material (blank).

3 MANAGEMENT AND SETTING THE PARAMETERS DONE THROUGH TOUCH PANEL Vacuum furnace has 100 programs. When switched on, the furnace is automatically set to the first program. Change the program is done through the blue button or «above» and «down» thereby changing the selected program to one, or by pressing the number of a selected program with the on-screen keyboard appears with which we write the number of programs that we want (from 1 to 100). Registration program ends with pressing the «ENT» after which it automatically loses keyboard on the screen.

5 STARTING THE PROCESS: Pressing the "Start "button starts the process. Second screen appears: If the drying temperature is not reached in the "Info" box of the second screen will show the message "Preparing to Start. " When the temperature in the chamber closer to the specified drying temperature ± 5 º C was the beginning of the process. The process begins to take place by the elevator rises in four steps for the given drying time. If the elevator was not in the down position when pressed the button «START» screen appears an error:

6 If you get this error process is terminated. Lift automatically lowers the bottom position. Pressure on the small screen error, the error disappears from the screen. That the process must be re-started pressing «START». When the elevator lift and close the chamber begins second phase of the process. In the second stage of the process includes a vacuum pump, if you select "Vacuum ON ". At the same time begins to increase in temperature in the chamber of the drying temperature to firing temperature in a given time. Sets warm-up time is done in the "heating". There are two ways of reaching the firing temperature setting. The first is in minutes and the second C per minute. Change the way is done by pressing the yellow bracket in the "warming" to the touch panel. When it reaches a temperature of firing off the vacuum pump and start the timer firing. Upon completion of phase firing drying stage begins. It takes place in four phases by lowering the elevator to the lower position.

7 When the elevator down to the lower position and count rate during the drying process triggers an audible signal in the info box says "END". This screen remains until you press the green field 'end'. During this time the heater is turned off. Pressing the «END» returns to the first screen and begins to achieve and maintain the temperature of drying. At any stage of the process it is possible to stop the process by pressing the «STOP» which the program returns to the beginning. During the process in the information field can be observed about the process. What is the phase in progress. How much time is left until the end of this phase. What is a vacuum in the chamber if the vacuum is selected. Also the order of stages ignited and LEDs on the front panel which will remain until the end that is until the end of the field is pressed END.

8 CHANGE PARAMETERS AND SAVE: Change the parameters of a program is done by pressing the current value of this parameter. Then at the touch panel keypad appears through which we enter a new value. When you enter a new value starts to "blink " blue text "Program" on the panel. Pressing the article "Program" new values are stored and shall cease to be "blinking" text. This is a complete change program. It is possible to modify several parameters of a program and then save them.
