AutoFire Slide Kiln Controller
Alarm Deviation
Allows the operator to set a temperature deviation value for activating the non-terminating deviation alarms; Fail
To Heat, Fail To Cool and Low Temp Deviation. To program the value, touch the field for a pop-up keypad. Key
in the value and SAVE. The default value is 100F or 56C
Note: for MAX ramp rates the deviation alarms are disabled for the MAX ramp segment regardless of this setting.
To disable the deviation alarms completely, set the value to 32F or 0C
Setpoint Alarm
Use this setting for an audible and visual alarm when the controller reaches a temperature. To program the value,
touch the field for a pop-up keypad. Key in the value and SAVE. The alarm is disabled with a value setting below
32F or 0C. You can program the alarm before you start the firing or reset it during the firing.
When the kiln reaches the alarm temperature, the Threshold Alarm will appear and the buzzer will sound. Silence
the alarm on the Status screen.
Over Temp
Allows the operator to set a temperature deviation value for activating the controller's terminating over-
temperature alarm. To program the value, touch the field for a pop-up keypad. Key in the value and SAVE. The
default value is 100F or 56C
Note: The overtemp alarm cannot be disabled. The maximum deviation value is 200F or 111C.
Power Balance
The balance option only appears if the controller is configured for 1 thermocouple and more than one relay output.
The setting changes the amount of power being supplied to the top and bottom heating elements by selecting a
power percentage between 0% and 200%. This is the percentage of power going to the top heating elements.
Values less than 100 reduce power to the top, while higher values increase power to the top. The power to the
bottom heating element is automatically changed. This feature can be used if the kiln is not heating uniformly.
100% is the factory default. This applies 100% of available power to both the top and bottom elements. Changing
the setting to 150% would increase the power to the top elements by 50%, while decreasing power to the bottom
elements by 50%. The balance can be changed in increments of 10%. To adjust the setting use the arrows to
increase or decrease the value.
Center Power
The Center power option only appears if the controller is configured for 1 thermocouple and 3 relay outputs.
The setting changes the amount of power being supplied to the center heating elements by selecting a power
percentage between 0% and 200%. This is the percentage of power going to the center elements. Values less than
100 reduce power to the center, while higher values increase power to the center. This feature can be used if the
kiln is not heating uniformly.
100% is the factory default. This applies 100% of available power to the center elements. Changing the setting to
150% would increase the power to the center by 50%, The balance can be changed in increments of 10%. To
adjust the setting use the arrow to increase or decrease the value.
