Abrt The firing was stopped.
COnE (page 8) This is the prompt for Cone-Fire mode.
Press the START key to select Cone-Fire. The controller is then
ready for you to select a pyrometric cone number.
CPLt Fired to completion. If the kiln is already hotter than the
programmed target temperature when you begin firing, CPLt
will appear immediately after you begin firing.
dELA (page 3) Delay is a count-down timer that starts the
kiln when the time runs out.
°F or °C (and temperature) (pages 5 & 6) The target
temperature (the temperature that the kiln will fire to). Each seg
-
ment in Ramp-Hold has a target temperature. Single Segment
mode has one target temperature.
FULL Full power firing rate. At this setting the kiln will fire at
its fastest rate. There are two ways to select full power:
1) Select SPd5 in Single Segment mode.
2) Select a rate of 1799°F/999°C at the ra _ prompt in
Ramp-Hold mode. A fast way to do this is to press the Down Ar
-
row key once from 0000 . FULL will appear.
HLd (and time) (pages 5 & 6) Hold time of a segment,
shown in hours and minutes. (i.e. 2 hours 15 minutes = 02.15.)
IdLE (page 3) The controller is ready for you to enter a pro-
gram or to begin a repeat firing.
-On- Firing has begun. A moment after -On- appears, you
will hear the relay(s) clicking.
ProG (Program) (page 6) Select this option to program a
Ramp-Hold firing.
rA 1 , rA 2 , etc. (Rate) (page 6) This appears in
Ramp-Hold programming for each segment. 1, 2, etc. are seg
-
ment numbers. Enter the rate of temperature change for that
segment. Rate is figured in degrees of temperature change per
hour. Example:
A temperature rise of 100° in two hours = 50° rate.
A temperature drop of 200° in one hour = 200° rate.
SPd1 , SPd2 , SPd3 , SPd4 , SPd5 (page 5)
These are firing rates, or speeds, in Single Segment mode.
SStP (Skip Step) (page 6) This message appears when you
press the Up Arrow key during a Ramp-Hold firing. If you press
the Up Arrow key again, the firing will skip to the next segment.
StOP The firing was stopped by pressing START/STOP.
Strt The “Ready to Start” message appears after program
-
ming a firing. Press START/STOP to begin firing.
Trouble Shooter
Problem: Controller display is blank.
No heat in kiln.
I
Is the kiln connected to the power?
I
Has the circuit breaker tripped or fuse blown?
I
Is power reaching the wall receptacle?
Test with a voltmeter or test light if you are not sure.
I
Has the kiln switch box ½ amp fuse blown?
The kiln’s ½ amp fuse is lo
-
cated in the kiln switch box. Re
-
move by pressing the fuse holder
and turning counter-clockwise
half a turn. Check the fuse by
placing the probes of an ohmme
-
ter on the ends of the fuse. If the
ohmmeter reads less than an
ohm (digital meter) or reads 0
ohms (analog meter), the fuse is
okay. If the reading is OPEN (digital meter) or infinity/no
needle movement (analog meter), the fuse is bad. Replace

I
Is the controller receiving power? Test the power IN-
PUT connections on the back
of the controller with a volt-
meter.
Controller Power Input Test
Unplug the kiln. Remove the 4
screws holding the controller
faceplate to the switch box. Lift
faceplate out of box and let the
board hang on the box with the
back of the board facing you.
Plug the kiln back in. Touch voltmeter probes (in AC mode)
to both INPUT connections (the white and orange wires).
Caution: Do not let the back of the board touch a
grounded object. Make sure the voltmeter is in the
AC mode when placing the probes on INPUT con
-
nections.
Controller Power Input Test Result: No voltage
UNPLUG kiln. Check the switch box for disconnected
wires between the cord, transformer, and controller. If wir
-
ing is okay, replace the transformer.
Controller Power Input Test Result: 20 - 24 volts AC
Correct current is reaching the board from the trans
-
former. But since the board is not lighting up, it is probably
defective. Return the controller for repair or replacement.
Controller Power Input Test Result: less than 20 volts
Did you recently replace the transformer? It may be the
wrong voltage. The voltage is below 20, which is not enough
