Changing the Deviation Temperature
If an alarm is triggered by flash-cooling the kiln or open-
ing a bead door, raise the
[TEDE]
temperature.
1
From
[IDLE]
, press the
Up Arrow
repeatedly until
[TEDE]
appears.
Note:
With each
Up Arrow
key press, you will see
the next option. When you see
[EXIT]
, press the
Up Arrow
again to see more options. When
[OPT2]
appears, press
Start/Stop
. That will take
you to more options.
2
When you see
[TEDE]
press the
Start/Stop
key.
3
Change the deviation temperature with the arrow
keys. The higher the number, the less likely you will
activate the alarms.
4
Press
Start/Stop
.
[IDLE]
will appear.
Note:
The factory default
[TEDE]
setting is 100°F /
56°C.
Example:
The Fail to Heat code
[FTH]
appears during
a firing when the kiln cannot heat as fast as programmed.
The Temperature Deviation
[TEDE]
is set to 100°F / 56°C.
The Fail to Heat code will appear if the temperature is
100°F / 56°C or more below the set point.
HTDE / Adjust High
Temperature Deviation
Change The High Temperature Shutoff Setting
The
[HTDE]
setting is the amount that the kiln tempera-
ture can exceed the programmed temperature before the
kiln shuts off. The factory
[HTDE]
setting is 100°F / 56°C.
The adjustment range is 18°F - 200°F / 10°C - 111°C.
1
From
[IDLE]
, press the
Up Arrow
repeatedly until
[HTDE]
appears.
Note:
With each
Up Arrow
key press, you will see
the next option. When you see
[EXIT]
, press the
Up Arrow
again to see more options. When
[OPT2]
appears, press
Start/Stop
. That will take
you to more options.
2
When you see
[HTDE]
press the
Start/Stop
key.
The current high temperature shutoff setting will
appear.
3
Using the arrow keys, change the deviation temper-
ature. The higher the number, the less likely you will
activate the alarms. Then press the
Start/Stop
key.
[IDLE]
will appear.
Note:
The adjustment range is 18°F - 200°F / 10°C -
111°C. The most sensitive setting is 18°F / 10°C.
The higher the number, the looser the setting. Use
a lower number when you want the kiln to shut off
if it can’t keep up with your program. Use a high
number if the kiln shuts off when you don’t want it
to, such as when the lid is vented or a bead door is
open when you load a bead rod.
CAUTION:
The High Temperature Deviation
(HTDE) alarm shuts off the kiln to prevent an
overfire. On controllers with pre-18D software,
entering a temperature deviation of 0 turns off this
important alarm!
LOCK / Program Lock
Tamper-Proof Individual Programs
By default, Program Lock is inactive. When it has been
activated, a stored Cone-Fire or Ramp-Hold program can-
not be altered or removed from memory unless you enter a
passcode. Use Program Lock for repeat firings that you
don’t want to inadvertently change.
The pre-installed passcode is the number
3
. You can
change the passcode to any number combination of one to
four digits.
If you forget your passcode, you can reset the controller
back to the factory settings using the
[RST]
option, page 24.
The passcode will then go back to the number 3.
Note:
Program Lock does not save a Delay setting.
While a program is locked, you can enter a new
Delay.
How to Activate the Lock Option
1
From
[IDLE]
, press the
Up Arrow
repeatedly until
[LOCK]
appears.
Note:
With each
Up Arrow
key press, you will see
the next option. When you see
[EXIT]
, press the
Up Arrow
again to see more options. When
[OPT2]
appears, press
Start/Stop
. That will take
you to more options.
2
When you see
[LOCK]
, press the
Start/Stop
key.
3
[PASS]
will appear.
4
Press the
Up Arrow
3 times to enter the default
passcode,
3
. Then press
Start/Stop
. (If you use the
wrong passcode, the display will return to
[IDLE]
.)
5
Use the keys to choose
[SET]
or
[OFF]
. (SET
means you are setting a new passcode. OFF means
you are not setting a new passcode and are not going
to lock programs.) Then press
Start/Stop
.
6
If you chose
[SET]
, then use the arrow keys to enter
a new passcode. It can be a number of one to four
digits. Press
Start/Stop
.
[IDLE]
will appear. Be
sure to write down your new passcode. The inside
cover of this manual would be a good place to store
your passcode.
How to Lock Individual Programs
After you have activated the
[LOCK]
option by selecting
[SET]
, you will be able to lock the Cone-Fire program that
is in active memory, or any Ramp-Hold program. Each
Ramp-Hold program can be individually locked or left un-
locked.
Keep the kiln lid or door closed when the kiln is not in use.
