Orton controllers store the firing program information in memory when turned off. If power is lost during a firing, the controller remembers how far the firing has progressed and determines if it can resume the firing when power is restored.

AF4X Kiln Controller Firing Methods and Features User Program method: Create up to 25 custom firing schedules with unique heating and cooling rates, • target temperatures and hold times. This method can be used for ceramics, heat treating, glass fusing, enameling or jewelry applications.
Place a series of Orton Self-Supporting Cones on the middle shelf of your kiln so that they can be seen through a kiln peephole. Use a series of cones close to the final firing temperature (see Appendix C). For example, if firing to 1945°F (Cone 04), use a Cone 03, Cone 04, and Cone 05 for the test firing.
AF4X Kiln Controller When the Controller is first turned on The controller runs a brief self-diagnostic test. The display will light up and the audible alarm should beep. After a few seconds, the display will alternate between the kiln temperature and IDLE. IDLE is the mode where the controller is not actively firing the kiln or being programmed for a firing.
AF4X Kiln Controller User Programs 25 User Programs are available. The User Program mode allows you to customize your firing schedule and specify how fast the kiln heats or cools to any temperature. All Programs allow 20 ramp steps. Each ramp step consists of a heating rate (or cooling rate), a target temperature and a hold time.
AF4X Kiln Controller A Program Review will show the message FULL to indicate the uncontrolled rate. Deviation alarms will not be active during the heating/cooling ramp. Caution: Overshoot in temperature may occur when a kiln is heating at full power, especially at lower temperatures.
AF4X Kiln Controller Set-Point Hold You can program the controller to hold at a temperature indefinitely by programming a Hold Time of 99.59. The controller will hold the kiln temperature until the Program/Stop key is pressed. Adding Time to a Hold If the kiln is firing and you need to increase the hold time, use the HLDT option.
AF4X Kiln Controller The controller will advance to STRT. The programmed firing schedule is automatically stored and ready to START the firing. If the Delay Start feature is active, the display will show DELA alternating with a Time value. use the Increase or Decrease key to set a time for the kiln firing to begin.

Some alarms will terminate the kiln firing while others allow the firing to continue with the alarm condition on the display.

AF4X Kiln Controller The options list will vary depending on the controller configuration. If the program loaded is not a CONE program, Cone fire options do not appear. Level 1 Options Skip Step - SKIP The Skip option allows you to end a ramp segment or hold period before the time has expired, use the SKIP option to advance to a later ramp in the program.
AF4X Kiln Controller Threshold Alarm -ALAR To sound an audible alarm when the controller reaches a temperature, Use the ALAR option. When the kiln reaches the alarm temperature, the display will flash ALAR and the buzzer will sound. Silence the alarm by pressing any key except Stop. Pressing Stop ends the firing.
AF4X Kiln Controller Level 2 Options Cone Offset - OFST This offset feature allows you to adjust the final heating step of the Cone programs. This is useful when the kiln does not quite bend witness cones to the desired angle. Cone Offset is a calibration feature that allows a temperature offset for the final heating ramp of the cone program.
AF4X Kiln Controller Program Lock Mode - LOCK The LOCK Option allows individual User Programs or a Cone Fire programs to be locked into memory, preventing the settings from being changed. LOCK requires a passcode to enable this feature, the default passcode is ‘3’. Once enabled, the user can set a new passcode that is private.
AF4X Kiln Controller Ramp Rate Units - RATE The RATE Option sets the units for programming and review of heating and cooling rates. The factory default setting is for Degrees per Hour. Settings Meaning MAX ‘FULL’ rate HOUR Degrees per Hour 999°C (1799°F)/Hour Degrees per Minute 16.65°C (29.97°F)/Minute...
Computer software Computer software is available for remote monitoring and datalogging. The controller has a USB interface that outputs TIME, Temperature and Setpoint data. For more information on the optional computer software, contact Orton or visit www.ortonceramic.com Speed Programs 5 speed programs are preset firing schedules with different fixed heating rates. These programs are single set-point (one step) programs.

This process more accurately fires to the cone number selected. When the heating rate slows, cones deform at slightly lower temperatures. At faster heating rates, cones deform at slightly higher temperatures. This ability to recalculate and to fire to a cone value is a unique, patented feature of all Orton controllers.
AF4X Kiln Controller Note: the Conefire Programs can be removed from the controller selections. To disable a program set, see the configuration appendix of this manual. Cone-Fire Programs During programming, default values may appear in the display. If the controller was previously programmed, the last settings will appear.

AF4X Kiln Controller Reference Section Appendix A – Low Fire Cone Programs Cones O22 to O11 The low fire range is typically used to fire decals or decorations. Some decals, lusters, and gold have a limited firing range and may need to be fired more slowly. The complete firing schedules for Cones O22 to O11 are shown below.
AF4X Kiln Controller Appendix B – Mid Fire Cone Programs Cones O10 to O1 This firing range is used to fire earthenware and low temperature glazes. If the ware is not thoroughly dried, a preheat cycle can be added. With lead-free glazes, a 10 to 20 minute hold is beneficial. Earthenware or other bodies containing ball clays, talc, and kaolin contain compounds such as water, carbon, and sulfur that are burned-off during the firing.
AF4X Kiln Controller Appendix C – High Fire Cone Programs Cones 1 to 10 The firing range of higher temperature bodies, such as stoneware and porcelain varies between Cone 4 and Cone 10. These bodies are fired nearly to vitrification and can shrink up to 16%. As with earthenware bodies, water, carbon, and sulfur are potential burnout materials and venting is important to remove gases generated.
