9 INTRODUCTION The Pentron porcelain furnace uses the latest in new technology to provide the user with many new features: Sixty user programmable porcelain programs numbered Thirty-seven custom porcelain programs numbered User updates of the operating system for the latest features via PC or Jenerator 2000* library module. RS-232 and RS-485 serial communications port for downloading/uploading system information. Night Mode with night/purge capability. Test Mode for operating system checks. Absolute vacuum reference sensor: true vacuum readings not affected by altitude. Small footprint. Programs may be temporarily adjusted during firing. Holds programs and set-up information indefinitely without batteries. Simple programming and front panel indicators provide for simple and efficient use. Night mode for energy efficient operation. Temperature display and programming in C or F. Self diagnostics. 16-bit microcontroller. Fully machined high quality aluminum muffle for lowest possible vacuum leakage. Special fast muffle cooling feature. Many user configurable features (see OPTIONS). There are five modes of operation available: 1) PORCELAIN for porcelain firing. 2) CUSTOM for special porcelain firing with up to eight segments of control. 3) SETUP for specifying system parameters and calibration. 4) TEST for testing system functions. 5) NIGHT (optimal) for overnight operation at lower temperatures with optional auto purge. The front panel provides the user with a 2 line by 16 character alphanumeric LCD backlit display, keypad, and red LED indicators. The LCD display provides the user with the operating menus, temperature, time, program numbers, and mode information. The LED s indicate the segment being edited or executed. Also, there is an LED for idle temperature that goes on when the muffle temperature is plus/minus 50 C of the idle temperature set point. A VACUUM ON LED is provided to indicate when vacuum is required. The LCD display will indicate an actual vacuum by displaying a V on the bottom line, right most character. NOTE: THE VACUUM LEVEL CAN BE DISPLAYED IN PLACE OF THE TEMPERATURE BY PRESSING THE VAC KEY. Pressing the VAC key again will toggle the display back to temperature. The work platform can be raised or lowered using the UP or DOWN keys. The first time the arrow key is pressed will move the platform in the appropriate direction. If the key is pressed again, the platform will stop. The muffle will automatically close after 15 minutes of no activity. This feature can be optionally turned off. Pressing the NIGHT key while running a porcelain cycle will automatically initiate a NIGHT MODE after the *Jenerator 2000 is a trademark of Pentron, Inc. JP1200 Porcelain Furnace Manual Rev 4 7

10 cycle is complete and the muffle is cooled to night mode temperature. To speed processing of work, the furnace will cool the muffle using air drawn through the muffle by the vacuum pump. This feature will run at the beginning of the Porcelain and Custom modes, and at the end of the Porcelain and Custom modes. This feature can be optionally turned off. In the Porcelain and Custom modes, the SKIP key can be used to skip the predry and cool segments while running in that segment. Program edits and edit on the fly features may be disabled for labs wishing to have control over program revisions (see section OPTIONS). 1.0 Menu Selection After the initial power up test, the following information is displayed: TEST OK <ENT> GO TO IDLE Press the ENTER key.

12 2.1 PORCELAIN MODE RUNNING The Figure 1 illustrates the parameters of the porcelain cycle: Figure 1. Parameters of the Porcelain Cycle. Table 1. Parameters that correspond to the porcelain cycle program Parameter Description Unit Range START TEMP T1 Entry temperature Degrees (C or F) C ( F) PRE-DRY Time for stepped Minutes 00:00 99:00 muffle closure at START TEMP RATE Rate of Degrees per minute C (0 392 F) temperature rise V LEVEL Vacuum level mm of Hg (mercury) C V START Vacuum start Degrees (C or F) C ( F)* temperature V RELEASE Vacuum release Degrees (C or F) 1160 C ( F)* temperature HIGH TEMP T2 Firing temperature Degrees (C or F) C ( F)* HOLD Time at HIGH Minutes:Seconds 00:00 99:99 temperature T2 COOL Time for stepped Minutes 00:00 99:00 muffle open * See section on Firing Offset. The porcelain program starts by ramping up (or down) from idle temperature to the T1 temperature. If the initial temperature is greater than T1, the vacuum pump will be turned on to draw cool air through the muffle. The pump will continue until the temperature lowers to within 5 C of T1. Once the T1 temperature is reached, the muffle will start to close in approximately 10 one-inch steps over the programmed predry time. When the predry time is reached, the muffle will be closed and the temperature will ramp up to the programmed T2 temperature at the programmed rate. During the temperature ramp up, the vacuum will turn on at the programmed vacuum start temperature and regulate at the programmed vacuum level until the vacuum release or T2 temperature is reached. The VAC key may be used to toggle between temperature display and vacuum level at any time. When T2 has been reached the system will hold the temperature at the T2 level for the programmed hold time. When the hold time has expired, the muffle will be opened over the programmed cool time in approximately 10 one-inch steps while the muffle temperature is dropped to the T1 temperature. 10 JP1200 Porcelain Furnace Manual Rev 4

13 At the completion of the cycle the vacuum pump will be turned on to draw cool air through the muffle. The pump will continue until the temperature lowers to BELOW T1 temperature. The temperature will be controlled until stable at the T1 temperature by cycling the vacuum control valve on and off. While the cycle is running, the display will show the mode, time to finish, program number, temperature (or vacuum level) and segment. PORC. 10:00 P C RATE V The time displayed during the cycle is a countdown time starting from the T1 point until the end of the cycle. Use the VAC key to toggle between temperature and vacuum displays. Whenever a vacuum level is present, a V will be displayed in the lower right of the LCD display. The SKIP key can be used to skip the pre-dry and cool segments while running in that segment. During the cycle, the EDIT ON THE FLY feature can be used to modify the T1, T2, H1 (HOLD time), C1 (cool time), or RATE. Time will be recalculated if any time related parameter is changed. See EDIT ON THE FLY. During the cycle, the NIGHT key can be pressed to initiate the night mode at the end of the cycle. When the cycle is complete, the muffle will cool to 200 C, then close. The NIGHT mode will then run. 2.2 PORCELAIN MODE EDIT In general, use the UP and DOWN keys in edit mode to select the next parameter to edit. The number keys are used to enter a value. Corrections can be made by typing over the existing value displayed. The ENTER key must be pressed to save any modified parameter. The ESC key is used to back out of the edit mode. A red LED on the front panel will light for the section of the program being edited. NOTE: If the edit function is disabled, the ENTER key will not change the values that were input. The values can only be viewed with the UP/DOWN arrow keys. To edit a porcelain program, press the MODE key after the program number has been selected.

Example: If the H1 hold time is changed from 10:00 to 12:00 minutes during H1, the H1 time will start counting down from 12:00 minutes, if cool time is set to 0:00 minutes. If cool down time is set for 1:00 minute, display time will count down from 13:00 minutes. New total times are calculated for any changes made. JP1200 Porcelain Furnace Manual Rev 4 21

24 8.0 ERROR CODES/TROUBLESHOOTING ERROR 1 CPU/PCB error. Self-diagnostics have determined a problem with memory, program code, or a peripheral component. Turn the power off then back on. Consult the factory if the problem re-occurs. ERROR 2 Muffle current to low. During the power up diagnostics, the current in the muffle is measured and is out of normal operating parameters. Turn furnace off and back on. If problem repeats, the heating element may need replacing or the input power may be out of spec. See the OPTIONS section on displaying the current/voltage test results to determine if the current is too high or too low, and if the voltage is correct. When the option 1 is turned on, the power-on test will display the current reading on the upper left of the display, and the voltage reading in the upper right of the display after the power on test. This error can be bypassed by pressing the ESC key. ERROR 3 Thermocouple error. During the initial power on test, the muffle is turned on and the thermocouple is checked for an increase in temperature. If there is no temperature increase, the thermocouple is possibly defective or the furnace may be very cold (or HOT). Turn off the furnace and turn back on. If the problem re-occurs, consult the factory. Also see error below for open thermocouple. ERROR 4 Zero Vacuum calibration error during power on. The power-up diagnostics test has determined that the measured zero vacuum reading is higher than normal operating range for no vacuum. Press the ESC key to bypass the error and continue. NOTE: This error may occur if the furnace was shut off with a vacuum present or if the muffle was closed (as the muffle cools slowly, a vacuum may be created causing an error 4 when the power is turned back on.) ERROR 5 Muffle current too high. See error 2 above. ERROR 6 Heat Control error. The muffle current cannot be controlled properly, most likely from a shorted triac semiconductor. The main relay disconnects power to the muffle to prevent damage. Turn off the furnace and turn back on. If the problem re-occurs, consult the factory. This problem may also be caused by an extremely noisy powerline. OTHER ERROR INDICATIONS: RAPID BEEPING: OPEN THERMOCOUPLE. Consult the factory. OVER TEMPERATURE ERROR: The temperature has exceeded 1240 C internally. The main relay opens and the temperature control turns off. Turn off the unit and allow the unit to cool. Turn power back on, press the ENT key, and observe the temperature display. If the temperature goes above the IDLE temperature and still rises, turn off the unit and call the factory. SLOW BEEPING and front panel LCD error display: VACUUM ERROR. Pressing a key will continue the program. At the start of a vacuum section of a program, the vacuum level is checked for a minimum value for up to 16 seconds. If the minimum value is not reached, a vacuum error is displayed. 22 JP1200 Porcelain Furnace Manual Rev 4

25 VACUUM CHECK/TROUBLESHOOT The vacuum can be checked using the TEST mode. In TEST mode, pressing the START key will start the vacuum pump. If the pump does not start: check the power cord to the rear of the furnace, check the circuit breaker on the rear of the furnace (press to reset). check operation of vacuum pump by plugging it into AC outlet using adapter to verify pump runs. Close the muffle using the up arrow key. Press the VAC key to display the vacuum reading. If the pump is running and there is no vacuum: check the vacuum lines and connections for leaks, check the O ring on the muffle platform for tears or particles that may cause a leak, check mating surface, check the vacuum pump using a separate gauge, check for proper alignment of platform; it should close square to the muffle. If a vacuum is present but will not go up to the Max Vac setting: Press the 9 key while the vacuum level is present (the 9 disables the vacuum release when the vacuum pump is stopped). Press the STOP key. Observe the vacuum level. The level should not drop rapidly (a drop of 12 mm Hg in one minute is OK). NOTE: Press 8 and then the STOP key to release the vacuum before opening the muffle. Check the vacuum pump with a separate gauge and vacuum line. Check vacuum pump muffler for clog. Replace felt and clean assembly. NOTE: the muffler is the small screw-on fitting assembly at the location marked EXHAUST on end of whisper pump or outlet on Gast pump. Note: The Pentron Whisper Pump is recommended. Only use an oiless vacuum pump with 1/3 horse power maximum. The Pentron Whisper Pump requires maintenance cleaning upon installation and every 3 months to assure uninterrupted operation. To clean the pump, remove the brass cap from the exhaust fitting and clean the white air filter by removing it and using an air hose to clear any accumulated dust from the filter. Replace the air filter in the Whisper Pump and replace the cap. Failure to clean the air filter regularly can result in the filter becoming clogged which will trip the circuit breaker. If the circuit breaker does trip, clean the air filter then press the reset button on the furnace to resume normal operation. 9.0 PURGE PROGRAMS For purging the furnace there are two programs that may be used in CUSTOM mode. Program 98 is programmed at the factory for purging the muffle when used with porcelain only. Program 99 is programmed for purging the muffle with a carbon block when the furnace has been used with metal materials. To run the purge programs, select the CUSTOM mode using the MODE key. Enter the program number (98 or 99) and press the ENTER key, then press the START key. JP1200 Porcelain Furnace Manual Rev 4 23

Very short power failures will have no effect on the operation. Power failures that occur when a cycle was not running will recover with a standard power on test and the TEST OK screen. Any power failure of more than five minutes will abort the cycle running. In the event of power failures of less than five minutes, the action taken will depend on the mode and segment that was running and may result in the time or segment being adjusted to make up for the power off time OPTIONS The furnace can be configured to enable/disable various options in the SETUP mode. See the options listed below. To setup the configuration, view the existing S/W DIAG# number by using the DOWN ARROW key until MAX VAC is displayed. Press the MODE key twice. The S/W DIAG# is displayed. Add or subtract the number corresponding to the selected feature below and then enter the number. EXAMPLE: If the S/W DIAG# equals 000, then to disable the vacuum cooling in Porcelain, Press, and Custom modes, and show start up diagnostics display, add 3 to the existing S/W DIAG# number (1 + 2 = 3). This is the new S/W DIAG#. Enter 003 then press the ENTER key.

29 14.0 FIRING OFFSET (TEMPERATURE OFFSET) It is sometimes desirable to adjust firing temperatures to account for differences between manufactures materials and/or furnaces. Instead of adjusting each program value, a FIRING OFFSET value is used to raise or lower all the temperatures already programmed into a furnace. This feature allows the user to adjust the entire PORCELAIN and CUSTOM mode firing temperatures by entering one temperature-offset value. The FIRING OFFSET is defined in degrees C. THE FACTORY DEFAULT IS SET TO 25ºC. The maximum value is 40ºC and the minimum is 0 C. THE OFFSET ADDS TO THE ACTUAL CALIBRATED FURNACE TEMPERATURE. To raise the firing temperatures, add to this number. To lower the firing temperatures, lower the number. Example: To raise the firing temperature by five degrees, add five to the existing firing offset. FIRING OFFSET = 025 To raise by five degrees: Type in 030 and press the ENT key. To access the FIRING OFFSET VALUE: Scroll to SETUP MODE by pressing the MODE key until SETUP MODE is displayed Press the ENT key (to select SETUP MODE) Press the TEMP key Enter 9732 and press the ENT key FIRING OFFSET 0xx is displayed. FIRING OFFSET 025 Enter the new offset value and press the ENT key. NOTE: if the temperature needs to be increased by five degrees, enter a new number five degrees higher than the number first displayed. FIRING OFFSET 030 NOTE: The Firing offset value WILL NOT affect temperatures in idle, night mode, or temperature calibration TEMPERATURE CALIBRATION The temperature calibration can be done using various techniques. The recommended technique is to use the Pentron Laboratory Technologies, LLC Universal Silver Calibration kit (part number H77.) This kit comes with instructions. The following techniques can also be used if the above kit is not available. The temperature calibration procedure allows the user to set the temperature based on a reference temperature using the silver or gold wire melting point, or an external thermocouple. All temperature readings are then based on this calibration point, effectively raising or lowering the temperature readings referenced to one specific temperature point. JP1200 Porcelain Furnace Manual Rev 4 27

30 The thermocouple temperature calibration is based on an external meter, special insulator base, and thermocouple (available from Pentron). The base locates the thermocouple in the center of the muffle and insulates the lower platform. The external meter/thermocouple MUST be an accurate and calibrated system, since this is what the new calibration will be based on. NOTE: There is a Firing Offset temperature feature in furnaces with software versions starting at x ( x for Pressing Furnaces) This allows the user to offset the program temperatures for porcelain and custom modes. This Offset is independent of the temperature calibration PROCEDURE THERMOCOUPLE CALIBRATION With the power OFF, install the thermocouple/base/meter setup. Make sure the thermocouple is located in the center just above the base. Turn on the power. From the power up display TEST OK, press the ENTER key. Allow the furnace to warm-up for at least thirty minutes. Press the MODE key until SETUP MODE is displayed. Press the ENTER key to select SETUP MODE. Press the TEMP key to select temperature calibration. The display shows: ENTER CODE TO START TEMP CAL Enter 9731 and then press the ENTER key. The display shows: ENTER TEMP/MODE 000 C Entering the temperature value you want to calibrate the furnace at and press the ENTER key. The temperature should be in the range of C. The display shows: PRESS START WHEN STABLE xxxx C Wait until the meter temperature is stable (Changes less than 1 degree in one minute). When the temperature is stable press the START key. The display shows: ENTER METER TEMP xxxx C Enter the temperature displayed on the meter and then press the ENTER key. NOTE: ENTERING 0000 WILL ZERO THE TEMPERATURE OFFSET. The temperature calibration is complete. 28 JP1200 Porcelain Furnace Manual Rev 4

31 16.0 VACUUM CALIBRATION The vacuum calibration procedure allows the user to change the offset of the vacuum readings effectively raising or lowering the vacuum readings. The vacuum calibration is based on an external vacuum gage connected in between the vacuum pump and the rear panel vacuum fitting. The external gage MUST be an accurate and calibrated gage, since this is what the new calibration will be based on PROCEDURE Install the vacuum gage off of the furnace rear panel using a tee. Turn on the power. From the power up display TEST OK, press the ENTER key. Press the MODE key until SETUP MODE is displayed. Press the ENTER key to select SETUP MODE. Press the VAC key to select vacuum calibration. The display shows: ENTER CODE TO START VAC CAL Enter 9731 and then press the ENTER key. The display shows: ENTER METER VAC xxx mm Hg Wait for the vacuum gage to indicate a stable reading. When stable, enter the reading in mm Hg and press the ENTER key. NOTE: If the vacuum gage is calibrated in inches of Hg, multiply the gage reading by 25.4 to convert to mm Hg. The calibration is complete and the display returns to the setup mode: SET: IDLE TEMP _400 C JP1200 Porcelain Furnace Manual Rev 4 29
