To edit other segments, wait until the firing has progressed
to those segments.)
If the current segment has already started its hold time,
you can edit only the hold time.
1
During firing, press 4.
2
The display will show the rate of the current seg-
ment. Use the number keys to change the rate.
Then press
ENTER
.
3
The display will show the target temperature of the
current segment. Use the number keys to change
the temperature. Then press
ENTER
.
4
The display will then show the hold time of the cur-
rent segment (or
[00.00]
if there is no hold time).
Change the time, if needed, and press
ENTER
.
The kiln will resume firing.
The 5 Key / Present Status
Press
5
during a firing to display the current segment
that is firing. (See page 14 for the definition of segments,
rate, and hold.) The messages that can appear in Present
Status:
I
[RA
]
, the segment number, and the actual rate: The
Sentry is in the ramp part of a segment.
I
[HD
]
and segment number: The Sentry is in the hold
part of a segment.
I
[PRHT]
Cone-Fire Pre-Heat (see page 12).
I
[COOL]
Cone-Fire Slow Cooling (see page 13).
Uses for Present Status:
I
You are firing a program that contains several heating
and cooling segments. Without Present Status, it would
be easy to lose track of which segment is firing.
I
In Cone-Fire, you may think the kiln has fired too long
when it is actually only in a slow cooling.
Note:
Present Status shows the actual firing rate of
the current segment instead of only the rate you
programmed. This is very useful in knowing how
fast your kiln can actually fire.
The 6 Key / Program Review
Pointer:
Use Program Review before every firing!
It takes only seconds.
When you press
ENTER
to begin firing, the controller
will fire the program that is in active memory. Program Re-
view shows the values for that program. The program in ac-
tive memory is—
I
The program that you fired last, or
I
The program that you entered or selected since the last
firing.
Start Program Review from
[IDLE]
, or while firing, by
pressing
6
.
Note:
In Program Review, Cone-Fire speed is dis-
played as the RA part of each segment. Cone-Fire
Review shows the segments and ramp rates listed
in the charts on pages 32 - 33.
The 7 Key / Temperature Alarm
If you need to know when your kiln reaches a particular
temperature, set the alarm. The controller will beep and
[ALAR]
will flash when the kiln reaches the alarm tempera-
ture that you enter. Use the alarm to alert you to—
I
Lower the lid from the venting position and insert the
peephole plugs.
I
Check the witness cone near shut-off time.
I
Check the glass before the expected fusing or slumping
temperature. You can see the glass through a kiln win-
dow.
You can enter only one alarm temperature at a time.
However, after the alarm beeps, you can set the alarm for
another temperature, as many times as you want, during the
firing. Entering an alarm temperature automatically erases
the previous alarm temperature.
Note:
The alarm temperature that you set during a
firing must be higher than the current display tem-
perature. The alarm is designed only for higher
temperatures and not for cooling temperatures.
After the alarm beeps, the alarm temperature will stay in
memory for future firings until you replace it with a new
temperature.
Monitoring the Alarm from a Distance
Place an inexpensive baby monitor near the kiln. From
another location in your building, you will be able to hear
the temperature alarm beeping and even the relays clicking
if your kiln has mechanical relays.

Do not leave your kiln unattended during operation.
