Segments of custom programs may be used to ramp the temperature down and cool the kiln more slowly, if desired,
than it would if the kiln were turned off at the highest setpoint.
To change one value in a complicated RAMP HOLD profile without having to reenter the entire program simply
press ENTER to move through each value you wish to keep the same until you reach the one you wish to change. Then
enter the desired value, press ENTER, and continue.
To change a firing profile while the firing is in progress, press STOP. Use either CONE FIRE or RAMP HOLD to
enter new instructions for the remainder of the firing profile. Then press START to continue.
ERROR CODES
The following are error codes that may appear in the display window if the controller diagnoses a problem. If this
occurs, please reset the control by turning the power off, then on. If the problem continues call your dealer or Cress tech
support line at 702-884-4397.
ERROR #.
1
The program is ramping up and the rate of rise is 0 degrees per hour. The rate of rise is
checked every 7.5 minutes. Slow rate must persist for 22.5 minutes before the error is triggered.
2
The program is in hold and the temperature is 50 degrees or more above the hold
temperature. The error must persist for 18 seconds before the error is triggered.
3
The program is in hold and the temperature is 50 degrees or more below the hold
temperature. The error must persist for 18 seconds before the error is triggered.
4
The program is ramping down and the temperature is more than 50 degrees above the
last hold temperature. The error must persist for 18 seconds before the error is triggered.
5
The program is ramping down and the temperature is more than 50 degrees below the
local setpoint. The error must persist for 18 seconds before the error is triggered.
6
A negative temperature reading is detected. The thermocouple must be installed with
the polarity reversed.
7
The program is ramping up and the temperature is 50 degrees above the local setpoint.
The error must persist for 18 seconds before the error is triggered.
8
In CONE FIRE mode, the temperature is falling in the last segment instead of
increasing.
FAIL..... Open thermocouple.
PF...........Power failure
14
ERRP....Power failure. Press "cone Fire" to restart.
