Introduction
The easiest way to learn to operate your
controller is to read this manual while
you are sitting in front of your kiln. Press
the keys as you read the instructions.
Do not worry if you hear a clicking noise
during operation. Mechanical relays click
as they turn the heating elements on and
off. This is normal.
When you first connect the power, the
controller will display a software code and
then .
If your controller shows instead of a
software code before appears, then
the controller includes only Skip Seg-
ment from "Advanced Features" on pages
8 - 9. If your controller shows a software
code before appears, then the con-
troller has all the features in this manual.
Please read the manual. Damage caused
by failure to follow instructions is not
covered by warranty.
Once you learn the basic features of the
Sentry Xpress, you will be able to control
every stage of firing. This offers learning
opportunities and convenience difficult
to imagine with a manual-controlled kiln.
