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:
I
Defective thermocouple or disconnected/loose wires
I
Defective controller
I
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. Re-
move the controller. Remove 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 tem
-
perature, 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:
I
The temperature rise is less than 27°F/15°C per hour.
I
The firing is 4 hours longer than programmed.
See “Controller turns on. No heat in kiln,” page 11.
PF 1 / Power Failure
The power failedduring firing and temperaturedropped
more than 180°F/100°C by the time the power came back
on.
PF 2 / Power Failure
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” in the 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 controller
from the kiln. Leave the 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 tem
-
perature display. When the jumper connects two
pin-type terminals, display reads °F. When the
jumper is removed, display reads °C. Remove or in
-
sert the jumper as desired. (You can purchase the
jumperfrom a computersupply store if necessary.)
Install the controller being careful not to jar compo
-
nents on the back of the controller against the kiln
case.
