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.
