Pressing the STEP button, you can review the numerical values of the parameters (from LOW TEMP to VENT) and enter the correct values in their place. Upon completion, press ENTER to save the implemented changes in the system memory.

  • Page 18 Device application Select 0 to stop the program from going to OVERRIDE mode. -Mode 2: Press END and select “1” to enter the OVERRIDE mode. Thus, upon running each program in the firing cycle and upon expiring of HOLD TIME, the furnace gives the operator one minute to use the OVERRIDE capability.

    AT-100 Porcelain Firing Furnace mode. The difference between END and STOP keys is that the former does not fully stop the running program and can be used at any time during OVERRIDE. Another application of END is programming the furnace in three modes, namely, Mode 0, Mode 1, and Mode 2 (as was explained above).

  • Page 20: Idle Switch

    Device application can press STOP (See the DRY Program for more details). IDLE Switch IDLE Use this key to run the IDLE program while the furnace is idling and to maintain furnace temperature at the minimum tempera- ture (LOW TEMP). This would decrease the time required for the furnace to reach its lowest temperature as well as increase the useful life and speed of operation.

  • Page 21: C And F Switches

    The STOP key is used for stopping all running programs. Furnace Operation AT-100 Furnace Operating Press the ON/OFF switch (at the back) to turn on the furnace. Wait till the top door fully opens. Furnace Programming Your furnace can run 100 programs for different heating cycles with a maximum temperature of 1200 C.

  • Page 22: Program Parameters

    Device application Program Parameters Note: Throughout the instructions given on furnace operation, the abbreviation TEMP shall be used to denote “temperature”. 1.LOW TEMP: The temperature at which the furnace door be- gins to close. As soon as the door is closed completely, the heating cycle shall start at this temperature.

  • Page 24 Device application If VENT is expressed in minutes and seconds in the program, then it is equal to the length of time required for maintaining the vacuum level constant during HOLD TIME. VENT <= HIGH TEMP If VENT is expressed in minutes and seconds in the program, then it shows the length of time required for maintaining the vacuum level constant during HOLD TIME.

  • Page 25: Programming

    AT-100 Porcelain Firing Furnace Programming AT-100 Furnace Programming All the 100 furnace programs have 9 programmable parame- ters which are individually explained in the section on operating the machine and are essential for obtaining the heating cycle performance diagrams (shown on the panel display).
  • Page 26 Device application 1.Put the main switch on “ON” position. The furnace door opens and the left and right displays show the internal muffle temperature and the word “IDLE” respectively. 2.Press the PRG.NO (program number) to view the number of the last reviewed or executed program. 3.Enter your desired program number (for example P .01) by us- ing the numerical keys 0 to 9.
  • Page 27 RATE and the EAT RATE light on the diagram starts blinking. 7.Enter your desired value for HEAT RATE (for example, 56 C per minute) and press ENTER. The digital display automatically moves forward on the parameter, and the TEMP indicator light beside it is turned on while the HIGH TEMP on the thermal di- agram starts blinking, indicating that the final temperature pa- rameter is ready for programming/reviewing.

    Display and Revision of Parametric Values during Thermal Cycle Execution The AUTO THERM 100 (AT-100) vacuum furnace has been de- signed in such a way that the operator can revise the thermal cycle parameters even during execution. To do this, press PROGRAM EDIT key upon starting the pro- gram.

  • Page 30: Programming And Revision Of Other Programs During Main Program Execution

    Side settings Programming and Revision of other Programs during the Main Program Execution During the running of one of the main programs or any of the DRY, IDLE, or NIGHT capabilities, you can change or revise the information for other main programs. To do this without interrupting the running program, follow the same steps mentioned above for programming.

    5. Press STOP to end the execution of NIGHT. DRY Program The AT-100 muffle is made of the best insulating materials which are very light and resistant against absorption of moisture. If, upon the initial operation of the furnace, you observe leakage and vacuum loss, run the Dry program.

  • Page 33: The Allowable Limits Of Programmable Furnace Parameters

    The Allowable Limits of Programmable Furnace Parameters The following table shows the numerical values of the nine pa- rameters. When programming the heat treatment parameters, the max- imum and minimum allowable values must be observed. The system displays an error message if values other than those given in the table are entered.
