AutoFire® Kiln Controller User’s Guide

tC - Select Thermocouple Type Default Setting: Type “S”
The tC feature enables the user to select from type “K”, “N”, or “S” thermocouples. The controller uses this
information to apply the correct thermocouple calibration information to the millivolt signal received from the
thermocouple. The factory default thermocouple type is type “S” in order to keep kiln from overheating if
electronics are reset to factory default settings. The selected type is saved in memory.
ld - Specify RS-485 Node Identification Default Setting: 0
The Id feature is used to specify the kiln controller node for recognition by the computer. This is an
identification number from 0 to 15, when the controller is one of up to 16 controllers in a network connected to a
personal computer using Orton’s ControlMaster software product. For more information about
ControlMaster, refer to page 29 on Remote Control and Monitoring. The factory default RS-485 node
identification is 0. The selected setting is saved in memory. If multiple kilns are used in a system, the last
controller in the network needs jumper JPR1 installed (page 40), all other controllers should have it removed.
tEdE - Specify Alarm Value Default Setting: 100°°F (56°°C)
The tEdE feature enables the user to select a temperature deviation value at which an audible and visual alarm
will occur. The temperature deviation applies to the following alarms - FtH, FtC, LtdE and HtdE. When active,
the alarm displays the type of deviation and sounds the buzzer once every 10 seconds. The display alternates
with the actual kiln temperature. This alarm can be turned off by placing all zeros in display.
rEL - Specify Number of Relays Default Setting: 3
(UniTemp™ Model Only)
The rEL feature allows the user to specify the number of relays that will be used with AutoFire® UniTemp™
Models. The controller uses this information to control up to 3 independent heating zones. The specified value
is saved in memory. Uniformity control is disabled when only 1 relay is selected.
rHEo
A Unitemp controller provides the capability to adjust the cycling of the middle heating elements. This option
can be useful if the middle portion of the kiln runs slightly hotter than the top or bottom . A number from 0 to
200% , in increments of 5, can be selected. The default value for rHEo is 100. Values less than 100 will reduce
the power to the middle heating elements, while values higher than 100 will increase the power.
0--1 - Display Temperature of Both Thermocouples
(UniTemp™ Model Only)
The 0--1 feature is used to display the temperature of the top thermocouple (tC 0) and the bottom thermocouple
(tC 1) when two thermocouples are used with UniTemp™ Models. This feature allows temperature uniformity
to be evaluated during a firing.
tC0 and tC1 alternate with one another and will default back to current firing temperature in
approximately 20 seconds.
