Try pressing any key. If that doesn’t work, turn the power

off for 10 seconds. Call the factory if the error message re-
mains when you turn the power back on.
If you get an	message, check the wire connections

going from the back of the controller to the thermocouple.
A loose connection can cause the	message.

FtL / Fired Too Long

This message appears when both of the following condi- tions are met:

■The temperature rise or fall is less than 27°F / 15°C per hour.

■The firing is 2 hours longer than programmed.

Programming a cooling segment target temperaturethat is below or even close to room temperature can also trigger

the message.

14.See “Controller display turns on. No heat in kiln,” page

HtdE / High Temperature Deviation

Causes:

■During a heating-up ramp or a hold, the temperature is 100°F / 56°C above the programmed temperature.

■During a cooling-down segment, the temperature is 100°F / 56°C higher than the segment’s starting temper- ature.

■A fast rate caused the controller to overshoot the target temperature.

Also, check for a stuck relay.

PF 1 / Power Failure

The power failed during a cooling segment, and the kiln cooled past the target temperature while the power was off.

The kiln will not resume firing. To return to the dis- play, press any key.

PF 2 / Power Failure

The power failed during firing and kiln temperature was below 212°F / 100°C when the power came back on. The

kiln will not resume firing. To return to the display, press any key.

PF 3 / Power Failure

The power failed during firing and temperaturedropped more than 72°F / 40°C by the time the power came back on.

The kiln will not resume firing. To return to the dis- play, press any key.

tC / Thermocouple Failure

The thermocouple failed during the display. See the "paperclip" test under "FAIL," page 11.

tCL / Thermocouple Lag

The heating rate is slower than 9°F / 5°C per hour and the controller temperature is more than 100°F / 56°C away from the actual kiln temperature. To return to the display, press any key. Causes:

■On kilns that use a portable controller, the thermocou- ple has fallen out of the firing chamber.

■A bare spot on the thermocouple lead wires has touched a grounded object inside the kiln switch box causing the thermocouple to short out.

Check for worn or burned out elements, defective relays, low voltage and defective thermocouple.

tCr / Thermocouple Reversed

Thermocouple lead wires are reversed. Check that the thermocouple lead wires are connected to the correct ter- minals. See your kiln’s wiring diagram.
