User Programs (USER)
When youenter Ramp-Holdmode, thefirst promptto ap
-
pear is USER , meaning, “Select one of your programs.”
You, the user, can make your own firing schedules and store
them in memory. A firing schedule, or program, is the seg
-
ments needed for a firing. To make a segment, you will need
three facts:
■
rate(how fasttemperature changesindegrees perhour)
■
target temperature
■
hold, if any
The controller can retain four user programs in memory
even when power is turned off. User programs are num
-
bered from 1 through 4. User program #1 can have up to 20
segments. User programs #2 - #4 can have ten segments
each. You don’t have to use all 20 or all 10 segments—only
the number needed per firing. Often one segment is all you
willneed. AUser programcanbe assimpleas asingle ramp.
When using Ramp-Hold for the first time, press 1 when
USER appears. Your first firing will be stored as User Pro
-
gram #1.
Each time you store another program, select another
available number, such as 2, at the USER prompt. Adding a
program to a user number over-writes any existing program
stored there. Write down your User Programs.
Note: If you don’t need all the segments available
in a User program, zero out the unused segments.
First, enter values for the segments needed. At the
RA _ promptfor thesegment youdon’t need,press
0, then ENTER. The display will return to IdLE .
