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:
I
The temperature rise is less than 27°F / 15°C per hour.
I
The firing is 2 hours longer than programmed.
Programmingacooling segment targettemperature that
is below or even close to room temperature can also trigger
the message.

can appear if you program a segment for slow
cooling and the kiln is taking too long to cool. Pro-
gram a slower cooling rate. will also appear if
you program a cooling segment target temperature
that is below or close to room temperature.
HtdE / High Temperature
Deviation
(This error messageis accompanied by an audible alarm,
which sounds for one minute.) Causes:
I
During a heating-up ramp or a hold, the temperature is
100°F / 56°C above the programmed temperature.
I
During a cooling-down segment, the temperature is
100°F / 56°C higher than the segment’s starting temper
-
ature.
I
A fast rate caused the controller to overshoot the target
temperature.
I
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.
Error Messages
bAdP / Bad Programming
The kiln will not fire because a) the Ramp-Hold pro
-
gram just entered has a rate of 0000 in segment 1, or b) the
target temperature in segment 1 of Ramp-Hold is lower
than the current temperature.
EtH / Electronics Too Hot
The circuit board temperature is above 176°F / 80°C.
Press any key to return to .
To lower the board temperature, use a fan to blow air
across the kiln switch box into the louvers. (But do not blow
air into the kiln’s peepholes.) If you have more than one
kiln in the room, place them farther apart. Never allow the
firing room temperature to exceed 110°F / 43°C. (Measure
room temperature three feet away from the kiln.)
FaIL / Thermocouple Failure
The thermocouple, or temperature sensor, failed during
firing. Causes:
I
Defective thermocouple or disconnected/loose wires
I
Defective controller
I
Electrical noise
Thermocouple Paperclip Test
Check the thermocouple wire
connections. (See your kiln in-
struction manual.) If connec-
tions are tight, perform this test:
UNPLUG the kiln or dis-
connect the power. Remove the controller. Re
-
move the two thermocouple wires from the back of
the controller.
Cut a thin paperclip in half. Insert a U-shaped
paperclip piece, or other piece of thin wire, where
you removed the thermocouple wires.
Plug in the kiln. will appear. Press .
Test results:
A) If the controller displays room temperature and
after you press , replace the thermocouple.
B) If the display still shows after you press ,
return the controller for repair or replacement.
