AutoFire - Model AF4X -Variable PID Controller
The AF4X includes; protected switchboard, improved thermocouple connection blocks, Type K, N, S and R thermocouple support, 25 available user programs, 20 step user programs, preset program groups, diagnostics to measure kiln load amperage (requires current transformer hardware), adjustable high temperature deviation alarm, programmable high temp limit, Individual program locks, USB interface, more memory, high capacity relay outputs and a buzzer that can be disabled. 100% compatible with previous AFX controllers and all the great features of the larger AF4000. A direct replacement for SentryXpress4.0 and SentryXpress5.0 controllers.
Cone-Fire programs: The controller provides quick selection of preset Cone programs from Cone 022 to Cone 10. These programs are designed specifically for ceramic firings that require specific heat-work to properly bend an Orton Pyrometric Cone. Every Cone-fire program allows the operator to set an optional hold time at the final heating temperature for additional heat-work if desired. Every cone-fire program also allows the operator to select an optional firing speed that can shorten or lengthen the firing time by 20% for large or small kiln loads. Heat-work adjustments are automatically calculated and final firing temperatures are automatically determined by the controller based on actual kiln performance. This ensures the kiln firing will produce the perfect results even as the kiln ages and conditions change.
Wax Burn-out Programs: You can select one of three preset firing schedules for 5 hour, 8 hour or 12 hour firing cycles. This firing cycles heat to 1350F with a controlled cooling cycle to a 900F hold temperature. Each program allows adjustment of the 900F final hold temperature.
PMC Programs: You can select one of five preset firing schedules for PMC, PMC+ or PMC Gold. All preset programs are fixed firing cycles that cannot be changed.
