Sentry Industries Sentry 2.0 - Manual (Page 2)

2
Introduction
Thank you for purchasing the Sentry micro processor, our most advanced generation of digi-
tal temperature controllers. The easiest way to learn to operate the Sentry is to sit down in
front of it with these instructions and play with it. Spend time understanding the controller
before you begin to use it.
Damage caused by failure to follow instructions is not covered by warranty.
The Sentry operates in Cone-Fire and Ramp-Hold similar to the earlier DTC 600, 800, and
1000 series. If you are familiar with the earlier controllers, you can follow many of the same
operating procedures with the Sentry.
The Cone-Fire mode applies to ceramics only. If you purchased a heat treating, glass fusing,
enameling or jewelry furnace, your version of the Sentry will include only the Ramp-Hold
mode, not the Cone-Fire. In this case, please disregard “FAST,” “MEDIUM,” “SLOW,”
“Cone Fire” and “Cone #s” on your keypad.
If you purchased the TnF 2 portable controller, you should find a TnF 2 installation
instruction sheet in addition to these instructions.
Instructions for multiple-zone kilns are included in this manual. If you are not sure whether
your kiln is multiple-zone, look into the firing chamber. If you see two or three thermocouple
tips, your kiln is multiple-zone. If you see only one thermocouple, skip multiple-zone
instructions.
Do not worry if you hear a distinct clicking noise during operation. Mechanical relays click as
they turn the heating elements on and off.
You can connect your Sentry controller to a personal computer, which will allow you to graph
your firings and to monitor them from a distance. Ask for the computer inteface kit, which
consists of a cable, a computer chip for the back of the Sentry, and software for your
computer.
Once you learn the basic features of the Sentry, you will be able to control every stage of firing.
This offers learning opportunities and convenience difficult to imagine with a manual con-
trolled kiln.
