RAMP-HOLD PROGRAMMING
STEP
DESCRIPTION
1
Start with the display reading IdLE, Press “enter”.
2
Select ramp-hold.
If “r
-
Hd” is displayed, press “enter”, else press
an
arrow key to display “r
-
Hd” and then press “enter”.
3
Set delay start
–
The beginning of the firing can be delayed from the time
you press “start”. This allows the firing to start later and end when you
can supervise the end. Use the arrow keys to adjust the amount of delay
and press enter. **
Caution should be taken to make sure that no one
can place anything around or on the kiln during the delay start. Treat
the kiln as firing during the delay start. **
4
Enter user #.
The controller holds 4 user programs. This step chooses
which of the 4 programs you are going to use. Use the arrow keys to
display the correct user number and then press “enter”. To reuse a
previously entered program simply press “enter” for each value. To
change a program, just adjust the displayed value.
5
Choose number of segments.
All programs consist of 1 or more
segments as shown in the sample profile at the end of the manual. Each
segment has 3 parts
–
ramp rate (speed of temperature rise in degrees per
hour), soak temperature, and hold time at soak temperature. It is helpful to
draw your profile to see how many segments you need. Then use the
arrow keys to display the desired number of segments and press “enter” to
store the value.
6
ENTER RAMP RATE.
The rate is displayed in degrees per hour. Slow
rates range from 1-50 degrees per hour and are used for thick glass
projects. Medium rates range from 60 to 200 degrees per hour and are
used for thick, hand-built ceramics. Fast rates range from 250
–
1000
degrees per hour and are used for glazes, thin ceramics and small glass
projects. A rate of 9999 sets the kiln to ramp as fast as possible. Use the
arrow keys to adjust
the rate and press “enter” to
store the value.
7
ENTER SOAK TEMPERATURE.
For a single segment program, this
is the top temperature of the firing. For multi-segment programs, this can
be a temperature where you want to hold to dry the ware or for carbon
burn-out, or equalize the temperature across the item or it can be where
you just want to switch ramp rates without a hold. Adjust the temperature
with the arrow keys and press enter to store the displayed value.
8
ENTER HOLD TIME.
Use the arrow keys to adjust the hold time at the
soak temperature. Hours are displayed to the left of the decimal point and
minutes to the right (HH.mm). Use a zero (00.00) hold time to move to
the next segment without holding. Drying ware can take several hours
