above a Ramp temperature instead of a Hold temperature.

Err 6 Message

Problem:
Probable Cause:
Thermocouple Leads Hooked Up Backwards
Room Temperature Below 0ºF or 0ºC
Board Damaged by Static Electricity
UNPLUG kiln and remove the controller from the switch
box. If the yellow and red wires are attached to the incorrect
terminals (see diagram on page 22), reverse the wires. Rein-
stall the controller.
If room temperature is below 0ºF or 0ºC, raise tempera-
ture.
Perform the paperclip test described under "FAIL Mes-
sage," page 18. When the paperclip is in place, the board
should show room temperature. If it shows a negative number,
replace or repair the board.

Problem:
Probable Cause:
If the cause is a hot circuit board, open windows and use a
fan to circulate air in the room before firing the kiln or fur-
nace. If you have more than one kiln in the room, place them
farther apart. Never allow the firing room temperature to ex-
ceed 110°F/43°C. (Measure room temperature at least three
feet away from the kiln.)
If

above the programmed temperature. It can occur during a
ramp or during hold. Check relays as described on pages 15 &
16.
If you fire to around 300°F/149°C,
a temperature over-shoot. Fire at a slower rate.
Problem:
Probable Cause:
The controller detected a defective component on the cir-
cuit board. Replace the board.

Probable Cause:
The controller detected an error in a self-diagnostic check.
If the error persists, replace the board.

The write cycle to the non-volatile memory chip took too
long. Have controller serviced.
Problem:
Probable Cause:
There was a power loss to the controller while sending data
to a memory chip. Use "Program Review" to be sure your pro-
gram is still in memory. If you get an
troller may need servicing.
