Using The Keys - Honeywell UDC2000 Instruction Manual

Soak A
soak is a stage of firing where the temperature
is held steady for a certain length of time. There are two
adjustments for each soak: time and temperature.
SPRAMP: Set Point with Ramp SPRAMP firing, one
of three ways to fire with the controller, is a single-ra�p
firing program. You can select the temperature you will
fire to and the length of time you want the furnace to
take to reach that temperature. (See set point.)
SPPROG: Set Point with Programm in g SPPROG
firing is one of three types of firings you can do with this
controller. With the SPPROG firing program, you can
enter up to 12 stages of firing into the controller (six
ramps and six soaks). It uses the 12-segment program.
(See set point.)

USING THE KEYS

Plug your controller in. During normal temperature
display, which is what you see
after you first plug in, the top
part of the display window
shows the furnace temperature
in large numbers. The bottom
part of the display window is
blank. Press the DISP (display)
key. Each time you press this
key, the display window shows a different message.
The messages displayed on the bottom half of the
display window are of two types: operation and set-�p.
Operation messages tell you what your furnace or kiln
is doing while firing or while in normal temperature
display. Set-up messages guide you through all the
set-ups.
The set-up adjustments that you can make on the
controller are organized under a series of Set-Up Modes.
UP
Press the SET key. While the SET
down, the display window reading will take you throu � h
the eight Set-Up Modes one after the other. (See box thIS
page.) Or you can press SET
Mode. Each time you press the SET
see a different Set-Up Mode. The furnace temperature
disappears when the Set-Up Modes are displayed.
If you do not touch a key after a minute, the display
goes back to normal temperature display.
UP
Press the SET
key again to get one of the eight
Set-Up Modes in the bottom of the display. Then press
the top left FUNC (function) key. Each time you press
the FUNC key, you will see a
different message. These mes­
sages are the Function Mes­
sages for the Set-Up Mode you
are in. For instance, "CYC TI" is
a Function Message under the
"TUNING" Set-Up Mode.
FUNC
The key works only
when a Set-Up Mode is dis­
played. So i f y o u
"KEYERR" when you press
FUNC
the key, you are not in
a Set-Up Mode.

If you press the DISP key while a Set-Up Mode is
displayed, the controller display goes back to normal
temperature display.
The Function Messages are lists of adjustments that
you can make under each Set-Up Mode. After you use
the FUNC key to display a Function Message, you
use the up and down arrow keys to make adjustments.
Arrow keys will raise or lower time and temperature
settings and tum features on and off. If you make �
adjustment and then decide you want to go back to
setting you had before, you can do that by pressmg
RESET.
The RESET key will work only if the Function
Message is still displayed and you have not y�t
pre$sed the DISP key.
Exercise 1: Press the SET
UP
key until INPUT 1 appears
in the bottom of the display win­
dow. Then press the FUNC key
until UNITS appears in the dis­
play. Use an arrow key to
change the F to a C (or vice
versa). Now press the DISP key
to take you back to the normal
temperature display.
You have just changed the
temperature reading from OF. to
·C. (or vice versa). You entered
the INPUT 1 Set- Up Mode, and
changed the UNITS Function Message with an arrow
key. Now change the UNITS Function Message back to
the way you had it if you want.
