Operating instructions

3/DelayFire
This delays the start of
the firing by the amount of
time entered. Use it to fit a
firing into your schedule or
to take advantage of lower
electric rates at night. Delay
zeroes out after each firing.
Therefore, it must be pro
-
grammed again for each fir
-
ing. The maximum delay is
99 hours and 59 minutes.
First, enter the the
Cone-Fire or Ramp-Hold program you are going to
fire.
From press . Enter delaytime (i.e.,5 ½ hours
= 05.30). Press .
To begin Delay, press once from .A
Delay count-down timer will appear.
Note: Press during delay to end the delay and
begin the firing. (You could also press to end the
delay and then to begin the firing.)
CAUTION: For safety, do not leave the kiln alone
during a delay or a firing. We cannot guarantee your
kiln against overfiring even though the controller is au-
tomatic. The operator assumes full responsibility for
shutting the kiln off at the proper time.
4 / Ramp-Hold / Edit
Ramp-Holdfires thekiln tothe temperature you specify,
whereas Cone-Fire fires to a pyrometric cone. Press from
to program a firing or to select a stored program. See
“Ramp-Hold,” page 14.
Editing the Current Segment
During Ramp-Hold Firing
Note: This feature works only in Ramp-Hold, not in
Cone-Fire.
While the kiln is firing in Ramp-Hold, you can change
the target temperature and hold time of the current seg
-
ment. (You can edit only the segment that is firing. To edit
other segments, wait until the firing has progressedto those
segments.)
Even if the current segment has already started its hold
time, you can still edit the segment’s target temperature.
You can raise or lowerthe targettemperature.The control
-
ler will go back out of hold and fire to the new target tem
-
perature at the original rate. (You cannot edit the rate,
however.)
During firing, press .
The display will show the target temperature of the
currentsegment.Use the number keysto change the
temperature. Then press .
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 . The
kiln will resume firing.
5 / Present Status
Press during a firing todisplay the current segment that
is firing. (See page 14 for the definition of segments, rate,
andhold.) The messages that can appearin Present Status:
I
, the segment number, and rate: The Sentry is in
the ramp part of a segment.
I
and segment number: The Sentry is in the hold
part of a segment.
I
Cone-Fire Pre-Heat (see page 12).
I
Cone-Fire Slow Cooling (see page 12).
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.
6/ProgramReview
When you press 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 was fired last, or
I
The program that was selected since the last firing.
Start Program Review from , or while firing, by
pressing .
Note: In Program Review, Cone-Fire Fast speed dis
-
plays as . Slow speed displays as . (These
speeds are 20% faster and slower than the standard
speed.) See page 12.
