AF4X Kiln Controller
4
Introduction
This User’s Guide explains the features and operation of the Model AF4X Controller.
The controller has 3 keys for programming.
Orton
controllers use P-I-D control algorithms to tightly control kiln temperature. This eliminates temperature
cycling. Cycling occurs when the controller turns the kiln on or off in a way where the actual temperature does not
closely follow the desired firing schedule.
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.
Precautions
The controller is not a safety device. The controller operates relays to turn the kiln elements on and off. It is
possible for relays to fail in the ‘ON’ position. The controller cannot protect against relay failure. To prevent over-
firing, never leave the kiln unattended, especially at the end of a firing.
Controller accuracy and performance depends on the condition and position of the thermocouple sensors in use.
Getting Started
Read all precautions and instructions before using your controller.
If your kiln has manual control switches for the heating elements, turn all the dials to the highest settings.
If you have a Kiln-Sitter
on your kiln, you can use a Cone 10 bar under the sensing rod to shut off power if the
kiln reaches high temperatures. This bar will last many firings and can act as a backup safety device for the firing.
Features
The AF4X includes many standard features, a user-friendly keypad and robust temperature control software.
