Error Messages
BAdP / Bad Programming
The kiln will not fire because the program just entered
has a rate of 0000 in segment 1. Program the firing again.
EtH / Electronics Too Hot
The temperature of the electronic circuit board is above
158°F/70°C. This could damage the controller, so the firing
has been stopped. To prevent this, keep the firing room
cooler. Use better ventilation.
FaIL / Thermocouple Failure
The thermocouple, or temperature sensor, failed during
firing. Causes:
Defective thermocouple or disconnected/loose wires
Defective controller
Electrical noise
Thermocouple Paperclip
Test
Check the thermocou-
ple wire connections. (See
your kiln instruction man-
ual.) If connections are
tight, perform this test:
UNPLUG the kiln or
disconnect 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. If the controller displays room
temperature, replace the thermocouple. If it shows
, replace the controller.
TCR / Thermocouple
Reversed
Thermocouple lead wires are reversed.
FtL / Fired Too Long
This message appears when both of the following condi-
tions are met:
The temperature rise is less than 27°F/15°C per hour.
The firing is 4 hours longer than programmed.
See "Controller turns on. No heat in kiln," page 11.
PF 1 / Power Failure
The power failed during firing and temperature dropped
more than 180°F/100°C by the time the power came back
on.
10 Cone-Fire / Ramp-Hold
The power failed during firing and kiln temperature was
below 212°F/100°C when the power came back on.
tC / Thermocouple Failure
The thermocouple failed or was disconnected during the
display. See "FaIL," column at left.
Selecting °F or
°C Display
The controller can display temperature in either °F or
°C. If your controller shows a small display dot in the lower
right corner of the display, the temperature shown is °C. No
dot means °F. To change temperature display:
UNPLUG kiln or disconnect power.
Remove the four screws that hold the controller to
the front of the kiln. Carefully remove the control-
ler from the kiln. Leave wires attached to the con-
troller.
Look at the back of the controller. A plastic jumper
on the back of the board determines the type of
temperature display. When the jumper connects
two pin-type terminals, display reads °F. When the
jumper is removed, display reads °C. Remove or
insert the jumper as desired. (You can purchase
the jumper from a computer supply store if neces-
sary.)
Install the controller being careful not to jar com-
ponents on the back of the controller against the
kiln case.
