Operating instructions
Setting Alarm From Idle
1 From IdLE , press 7. ALAR will appear alternating
with the last alarm temperature entered.
2 Enter alarm temperature. Press ENTER. IdLE will
appear. (Enter 0000 to turn alarm off.)
Note: 9999, as an alarm temperature, automati
-
cally changes to the maximum temperature rating
of your controller.
When the alarm sounds, shut it off by pressing any key ex
-
cept STOP. (The STOP key does not work while an alarm
sounds.) If the alarm sounds as soon as firing begins, it is be
-
cause the alarm was set to a temperature below the current
temperature.
Setting Alarm During Firing
1 The alarm beeps while the kiln is firing. Press 7.
2 Enter the new temperature.
3 Press ENTER. The kiln will continue firing.
If you touch 7, enter a new temperature, and forget to
press ENTER, the controller will merely continue firing.
Note: When an alarm sounds, firing to completion
does not shut the alarm off.
9 / Cone Numbers
& Skip Segment
Cone Table
Look up a cone temperature with the 9 key.
1 From IdLE , press 9. CONE will appear, then the
cone, if any, currently programmed in Cone-Fire.
2 Enter a pyrometric cone number. Press ENTER. The
display will show the cone temperature. If you enter a
non-existent cone number, the display will show
CONE , ready for you to enter a different cone num
-
ber.
Note: Do not be concerned if the actual cone
shut-off temperature does not match the Cone Ta
-
ble. The temperature of a cone varies with firing
speed. The cone temperatures in Cone Table are
for self-supporting cones fired at a rate of 108°F /
60°C per hour during the last hour of firing.
Skip Segment
Skip Segment works only during firing. It jumps from the
current segment to the next one.
To skip a segment, press 9. SKIP will appear, then the
current segment. Press ENTER. (If you change your mind
and don’t want to skip that segment, don’t press ENTER after
SKIP appears. Instead, press 9 again. The firing will con
-
tinue in the same segment.)
Skip Segment in Cone-Fire
In Cone-Fire, Skip Segment works in Pre-Heat and Hold:
I
To skip out of Pre-Heat and begin the cone firing.
I
To skip out of Cone-Fire Hold. Slow Cooling will begin.
(If the firing does not include Slow Cooling, Skip Seg
-
ment will not end a Hold. Press STOP to end the firing.)
Skip Segment in Ramp-Hold
In Ramp-Hold, the firing will skip to the ramp of the next
segment from either a ramp or hold of the current segment.
(See page 12 for details on ramps, holds, and segments.)
Skip Segment Examples
For additional examples, see Chapter 4, pages 14 - 15.
Cone-Fire
I
In Cone-Fire you are firing to an 05 witness cone for the
first time. You select cone 04 with a 60 minute hold and a
slow cooling. After 30 minutes in hold, the 05 witness
cone bends to maturity. Use Skip Segment to end the
hold and begin Slow Cooling.
Note: Once you know how much hold time will
bend the witness cone, program that much hold for
the next firing.
Ramp-Hold
I
Skipping to a Cooling Segment: You have programmed
2167°F for a cone 5 glaze firing, followed by a segment for
controlled cooling. Watching the witness cone through
the peephole, you notice that cone 5 is bending at 2150°F.
Use Skip Segment to end the firing segment and begin
the one for slow cooling.
Note: Make a note of the temperature at which the
cone bent. Program that temperature for the next
firing.
I
Skipping to a Hold: Skip Segment does not skip from a
ramp to a hold. It skips to the next segment. If you need to
skip to a hold, program an additional segment with the
hold that you want. Then skip to that segment. Example:
Segment 1: rate 500°F to 1828
Segment 2: rate 200°F to 1750 with 30 minute hold
Enter/Start
I
Press ENTER after each step in program
-
ming a firing.
I
Press ENTER once to begin firing.
The Options Key
See Chapter 6, page 17.
The Stop/Back Key
You can stop a firing at any time (except
when the alarm sounds) by pressing STOP.
If you inadvertently enter Ramp-Hold,
Cone-Fire, or Options, you do not have to go through all the
prompts to get back out. Press STOP to go to IdLE .
The STOP/BACK key is also like the Back button on an
Internet browser. It works in Cone-Fire and Ramp-Hold
programming. It will take you back one step every time you
press the key.
