If you use rate as a ramp unit, the bottom display
during firing will not show time left in a ramp
(example,
11.30).
Instead it will show degrees per
minute (IIO-segment 1, 10 degrees per minute).
Entering Your Firing Schedule into the Controller
Have your Ramp/Soak Worksheet in front of you as
you enter it into the controller.
1.
Load your furnace or kiln following the
man
ual that
came with it. Close the door or lid.
2.
Press the controller
SET
UP
key twice;
SPRAMP
will ap

play;
SET
will
appear in the
top. You are now in the firing
schedule Set-Up Mode. If you
wait one minute before pressing
another key, the display will go

Once you are in the firing schedule Set-Up Mode, you
have the choice of entering either the single-ramp firing
(SPRAMP)
or the 12-segment firing
(SPPROG).
Note:
SET:SPRAMP
is the Set-Up Mode you have
to be in to program a firing schedule. Within the
Set-Up Mode, there are two types of firing
schedules:
SPRAMP
(single-ramp) and
SPPROG
(12-segment). Here's something that may seem con
fusing:
SPRAMP
appears in the lower display for
both the Set-Up Mode and for the single-ramp
program. But you'll know you're in the Set-Up
Mode when
SET
appears in the top window. If
you're in the single-ramp program, either
DIS
or
ENAb
will appear.

SPRAMP
and

are like Greek, but they
mean "Set Point with one ramp"
(SPRAMP)
and "Set

(SPPROG).
We are going to use
the
12-segment program, so we want to open
SPROG.
From the Set-Up Mode

press the

key.
If
both firing schedules are closed, you will
see
DIS:SPRAMP
and
DIS:SPPROG
as you press the

(enabled) in the top of the display.

The display now reads

enter the first segment your
firing is starting with. This will
usually be 1.

Press

again.

will appear in the
bottom of the display. Enter the
last segment of your schedule
using the arrow keys.

Using the

When entering time for

ramps, notice whether or not
there is a decimal point in the
upper display. If there is no
decimal point, the program is
adjusted for degrees of
temperature rise per hour. If
there is a decimal point, the
program is a djusted for
minutes.
The display shows one
hour and 32 minutes in seg
ment one, a ramp.
SET:SPRAMP
will appear when you come back to
the beginning of the schedule. This means you have
finished entering your program. Press

to get back
to the no

7.
Then press
RUNIHOLD
to start the firing.
After firing is completed, turn the element on
/
off
switch to the OFF position. Otherwise the controller
will heat your furnace at the last soak temperature
indefinitely.
Changing a Firing Schedule During a Firing
During a firing, the controller will not allow you to
change the firing schedule. If you get into the firing
schedule Set-Up Mode (using the
SET
UP
and
FUNC
keys) during RUN, you will find that you cannot change
any of the settings. However, if you first put the furnace
on HOLD with the
RUNIBOLD
key before getting into
the Set-Up Modes, you will be able to make changes.
After you put the furnace back on RUN, the segment
you were in during HOLD
will
fire with the original time
and temperature. This is even if you changed them
during HOLD. But the segments to follow will
run
with
the new settings.
How to Program a Delay Fire
A delay fire will give you the flexibility of not having
to be near your furnace or kiln during an entire firing.
For instance, if you normally arrive at your studio at
8
a.m., and a firing will take five hours, you can program
8
