Err5
The temperature is more than 50 degrees below the travelling set-
point temperature during a ramp segment where the temperature is
programmed to decrease. The temperature must stay 50
°
below this
set temperature for 18 seconds before the error is displayed.
Decreasing Ramp segment
> 50
°
F below travelling set-point temp.
Persists > 18 sec.
Err6
A Negative temperature is detected. This generally indicates the
thermocouple is connected incorrectly. To correct this situation,
ensure the red and yellow wires are connected correctly to the
controller and at all t/c junctions. You can identify the red lead on an
unmarked thermocouple with a magnet because a magnet will be
attracted to the red lead.
(-) displayed
Err7
The temperature is more than 50 degrees above the travelling set-
point temperature during a ramp segment where the temperature is
programmed to increase. The temperature must stay 50
°
above this
set temperature for 18 seconds before the error is displayed.
Increasing Ramp segment
> 50
°
F above travelling set-point temp.
Persists > 18 sec.
Err8
When using the Cone Fire Mode, the temperature is decreasing
during the last ramp segment indicating the a kiln sitter or timer may
have turned the kiln off or an element or relay failed during the last
segment.
Cone fire mode only
Temp. decreasing during last ramp segment
ErrP
Continuous ErrP in display. Indicates a long term power outage.
The kiln has been shut down. Press “1” to clear the display.
ErrP
ErrP and the current temperature are alternately flashing. To clear
the display, press the “1” key. If a firing was in progress, it will
continue.
Err-
The Err with a dash indicates there was a power loss to the controller
while writing a program to the non-volatile memory chip.
Turn the controller off and back on.
Recheck the selected program, and
reprogram if necessary.
ErrE
or
Errt
The controller software has detected a hardware error. The controller
must be returned for service.
Hardware error
Errd
The kiln temperature is more than 100
°
F above the travelling set-
point. If a zone control then any one of the zone temperatures is
more than 100 degrees F above the travelling set point.
Can be caused by a stuck relay or stuck
output. If zone control, then the outputs or
t/c's may be in the wrong zones
ErrA
Invalid program variable.
Reprogram; if problem persists return board
for service
StUc
Key was held too long or is stuck
If problem persists after releasing key have
key pad replaced
FAIL
Steady FAIL display then all thermocouples (t/c) have failed. If tC 1
alternately flashing with FAIL then t/c one in top section has failed.
tC 2 flashing with FAIL, then t/c 2 (middle section) has failed. tC 3
flashing with FAIL, then t/c 3 (bottom section) has failed.
Change thermocouple (t/c)
