This chart shows the segments in the four cone fire speeds. Notice that the firing profiles all end with segment 7 but they do
not start at segment 1. If you program a vary-fire to mimic these profiles you would start numbering with segment 1. The
profiles for other cone numbers are the same; only the end temperatures vary. The last segment always starts 250
°
F below the
cone temperature. The actual temperature reached during the firing will vary based on the rate of temperature rise during the
last segment. This ensures the correct amount of heat-work is done with each cone fire program.
APPENDIX B - ERROR CODES

Error
Code
Description Quick
View
Err0
Software Error. Recheck the selected program, and reprogram if
necessary.
If error persists, return controller for service.
Err1
The temperature is increasing less than 12 degrees per hour during a
ramp segment (in either cone fire or vary-fire mode), where the
temperature is programmed to increase. This slow rate must persist
for 22.5 minutes before the error is displayed and the firing stopped.
Pressing the "1" key clears the Err1 and briefly displays the
temperature and then the firing time at which the error occurred.

Temp. increase < 12
°
F/hr
Persists > 22.5 min.
Err2
During a hold segment the temperature rises to greater than 50
degrees above the hold temperature which was set. The temperature
must stay 50
°
above this set temperature for 18 seconds before the
error is displayed.
Hold segment
> 50
°
F above set temp.
Persists > 18 sec.
Err3
During a hold segment the temperature is more than 50 degrees
below the hold temperature which was set. The temperature must stay
50
°
below this set temperature for 18 seconds before the error is
displayed.
Hold segment
> 50
°
F below set temp.
Persists > 18 sec.
Err4
The temperature is more than 50 degrees above the previous hold
temperature during a ramp segment where the temperature is
programmed to decrease. The temperature must stay 50
°
above this
set temperature for 18 seconds before the error is displayed.
Decreasing Ramp segment
> 50
°
F above last hold temp.
Persists > 18 sec.
