Typical Profile For Programmable Models Above. Other Profiles May Be Formed. 4. The Type 30400 Automatic furnace is designed as a single set point controller which reaches and maintains one temperature value. Principles of Operation 1. Furnace: The furnace chamber is heated by four electric resistance heaters which are embedded in a refractory material. The chamber is insulated with a ceramic fiber insulation.

Unpacking 1. Visually check for any physical damage to the shipping container. Inspect the equipment surfaces that are adjacent to any damaged area. Open the furnace door and remove packing material from inside the furnace chamber. Vacuum the chamber prior to use to remove the insulation dust due to shipment. Two shelves are supplied with furnace. 2. Retain the original packaging material if re-shipment is foreseen or required.
Observe These Warnings Before Operating Your Furnace: WARNING Do not use in the presence of flammable or combustible chemicals; fire or explosion may result. This device contains components which may ignite such materials. WARNING To avoid burns, this furnace must not be touched on the exterior or interior furnace surfaces during use or for a period of time after use.
NOTE When performing the operations with the controller, remember that if more than eight to ten seconds elapse before the buttons are used again, the display screen will automatically switch back to displaying chamber temperature. If this happens, light up the front panel again and step through each parameter until you reach the point at which the interruption occurred. The parameter values you adjusted earlier, however, will not be lost or altered.
NOTE If the power to furnace is "turned off" or interrupted while in "tuning,"upon returning power to furnace, the controller display will indicate "LinE FAIL" because sampled data could be questionable. To restart tuning, refer to "Tuning" procedure. If the controller cannot maintain temperature setpoint, "tunE FAIL" will appear on display. First, correct problem responsible for not maintaining the temperature setpoint, then restart the "tuning" procedure.
Operation of 2 Ramp & 2 Dwell Programmable Models (F30420C-70, F30428C-70, F30420C-60-70, F30428C-60-70) Controls and Displays Digital Readout: The digital readout continuously displays chamber (upper display) and setpoint (lower display) temperatures unless the PAR (parameter) button is depressed. If a program is in either run, Hb or Hold, pressing "PAR" once causes the lower display to indicate the current segment of the program (r1, d1, r2, d2, or Hb) along with °C or °F.
Cycle Indicator: The amber cycle light will illuminate whenever the door is closed and the actual chamber temperature is less than the setpoint temperature. This light will go out when the door is open, when the chamber temperature has reached the setpoint temperature or when there is an over-temperature condition. Door Safety Switch: The door safety switch removes power from the heating elements when the door is opened.
The next three parameters - Proportional Band, Integral and Derivatives - are the three control parameters of a P.l.D. control system. These parameters will be set when you tune your furnace. (See Tuning.) Prop - Proportional Band. In.t - Integral Time. dEr.t - Derivative Time. HPl - High Power Limit (%) This parameter limits the average maximum power that is applied to the heating elements. Remember that this parameter does not reduce the voltage to the elements.
Operating the Controller CAUTION Do not exceed limitations for continuous or intermittent operating temperature shown in the General Specifications (in furnace manual). Exceeding these limits will result in severely reduced heating element life. Single Set Point Operation The programmable control can be used as a single setpoint control or as a programmable control. To use as a single set point control simply push up or down buttons to choose a specific temperature.
Push "PAR" until "SP" is displayed. Push "UP" or "DOWN" buttons and modify set point temperature. After "d2" dwell time has expired, thus ending the program, the last temperature level to be attained will be equal to "SP" temperature. For example, if after your program has been completed, you want the furnace to cool to ambient, set "SP" to 20. This will be the last temperature level attained. Push "PAR" until "LC" is displayed.
controller flashes and "Hold" is indicated at the "prog" parameter, the controller is in Hold. Now you are able to adjust all parameters. To restart the program, set "prog" to "run" again. Program Idle To stop program, push "PAR" button until "prog" is displayed. Push "UP" or "DOWN" buttons until "idle" is displayed. This will terminate program.
8 Ramp & 8 Dwell Multi-Programmable Models (Models F30430CM, F30438CM, F30430CM-60, F30438CM-60) Controls and Displays Digital Readout: The digital readout continuously displays chamber (upper display) and setpoint (lower display) temperatures unless the scroll button is depressed. If the scroll button is depressed and released, the lower display will indicate output power (OP) or setpoint (SP). This is referred to as the "short scroll.
WARNING To avoid electrical shock, this furnace must have the door switch connected and operating properly. If the furnace power light does not go out while the door is open, consult the Problem Solving section before proceeding. NOTE The two center push buttons are inactive and not used. Parameters Pnr - Program Number. The program number of the program you are are going to work with. By pushing the up or down button you can select a program numbered from 1 to 4. PR1 - Program Ramp Rate.
The next three parameters - Proportional (PB) Integral (+i) and Derivative (+d) - are the three control parameters of a P.l.D. control system. These parameters will be set when you tune your furnace. (See Tuning Your Controller.) Pb - Proportional. (+i) - Integral. (+d) - Derivative. The next two parameters - cutback low (cbl) and cutback high (cbh) - are to aid the control in preventing temperature overshoots and undershoots.
be running a multi-step program, set the furnace's setpoint to the value of PL1 (Program Level #1).) At the end of the minute, the "SP" indicator will stop flashing, indicating that the setpoint can no longer be changed. The A-T indicator will start flashing and continue to flash until the self tune has completed. Once the self tune is completed, adaptive tune takes over and the A-T indicator will remain illuminated.
Program Entry To Link Programs Together Push scroll button until "Cnt n" is displayed. Press and release the up and down buttons to switch between "Cnt y" (continue yes) and "Cnt n" (continue no). The effect of selecting "Cnt y" is to continue the program to the next program number. For example, if in program #3 you select "Cnt y," when program #3 is complete, program #4 will run automatically. Setting "Cnt y" in program #4 will initiate the start of program #1 upon the completion of program #4.
achieved. By pushing the up or down button the number of loops can be set at any value from 1 to 999. Set the Holdback Feature 5. Scroll through the main scroll list until "HB" is displayed. Push the up or down button to reveal the current value of holdback. The up or down button can now be depressed to scroll to the required value.
When the reset has been enabled, the parts of the display associated with programming will be extinguished and the controller will operate as a single setpoint control. NOTE The temperature control in these models is a programmable "and" automatic single setpoint device. When the program has ended, the controller will maintain the chamber temperature at a value equal to the last programmed level (PL) until the program is cancelled.
Exhaust tubing hook-up. NOTE Appropriate exhaust must be provided to remove smoke and gases produced in an ashing procedure. Using accessory tubing available from Barnstead/Thermolyne Corporation (part number AY408X1A for furnace temperatures less than 975°C, part number AY718X1 for furnace temperatures of 975°C or greater) or equal quality 2.5" I.D.
