Error Messages
BadP / Bad Programming
The kiln will not fire because the Ramp-Hold program
just entered has a rate of 0000 in segment 1. Program the fir-
ing again.
EtH / Electronics Too Hot
The temperature of the electronic circuit board is above
185°F/85°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
■
Disconnected thermocouple lead wires
■
Defective board
■
Electrical noise
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
Causes of the FtL message:
■
Low voltage
■
Burned out or worn heating element
■
Defective relay
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.
PF 2 / Power Failure
The power failed during firing and kiln temperature was
below 212°F/100°C when the power came back on.
TcO / Thermocouple Failure
The thermocouple failed during the
6
display.

Display
1 UNPLUG kiln or disconnect power.
2 Remove the four screws that hold the controller to
the front of the kiln. Carefully remove the controller
from the kiln. Leave wires attached.
3 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 in-
sert the jumper as desired. (You can purchase the
jumper from a computer supply store if necessary.)
4 Install the controller being careful not to jar compo-
nents on the back of the controller against the kiln
case.
