Sentry Xpress 5 Cone-Fire / Ramp-Hold
2
Do not leave your kiln unattended during operation.
Before You Begin
Thank you for purchasing the Sentry Xpress temperature
controller. As you read the manual, pull up a chair and sit in
front of your kiln so you can try out the keys.
The controller display messages are limited to four charac-
ters. If at any time you are confused by these messages, turn
to Display Messages on pages 28 - 29.
The back cover is a shorthand guide to programming, to be
used after you have read the programming instructions on
pages 10 and 13.
You can customize the programming (pages 10 and 13) by
adding or removing these steps:
Delay:
Schedule a firing for later. This works in all firings. Page 17
Fan:
If your kiln is set up with a vent and switch box outlet, or, socket, you can turn the fan on or
off for Ramp-Hold segments. Page 22.
Lock:
Passcode-protect individual Ramp-Hold programs. Page 21
Slow Cooling:
Enhance certain glazes in Cone-Fire mode. Page 17.
If you don’t need these features, streamline programming by removing their display prompts.
Turn to the pages shown above for 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. It is also normal for the temperature to fluctuate
up and down as the kiln heats up. Please don’t be concerned.
The warranty on your Sentry controller does not cover damage from
overfiring, regardless of the circumstances. It is the operator’s
responsibility to make sure the kiln turns off at the end of the firing.
We are constantly trying to find better ways to make kilns, and your kiln is extremely reliable.
Nevertheless, it contains mechanical parts that eventually wear out. In some cases, a parts failure
can lead to a kiln overfire. Therefore it is important that you occasionally check on the kiln during
operation. Although the kiln does not require constant attention, it should never be left unat-
tended. Please check the kiln especially during the later stages of firing.
Write notes on the controller features that you use. Then if you are away from your kiln for a
period, you can review your notes to refresh your memory. The cover shows the controller op-
tions at a glance. Use the cover as a quick index.
Use Program Review (page 5) every time you fire the kiln. This is your assurance that you are
firing the correct program. Check the program in the display against a written copy.
