[LOCK]
will appear at the end of Cone-Fire and
Ramp-Hold programming. This means the pro-
gram is unlocked.
2
To lock a program, enter the passcode using the ar-
row keys. Then press
Start/Stop
. (To leave the
program unlocked, do not enter your passcode.
Just press
Start/Stop
when
[LOCK]
appears.)
Note:
After you have locked a program, you will
see
[UNLO]
before you fire it. You don’t have to
enter your passcode to fire the program. The
passcode is needed only if you alter the program.
How to Unlock and Edit a Program
You have locked a program and would like to edit it. Go
into programming, page 13. One of the first prompts you
will see is
[UNLO]
. Enter your passcode with the arrow
keys. Then press
Start/Stop
and edit the program. (If you
don’t enter the passcode, you will not be able to edit the
program, but you can still fire the kiln with it.) After you un-
lock and edit a program, you can lock it again or leave it un-
locked.
Note:
If your kiln is used in a classroom, you may
want to lock only the programs that you don’t want
students to change.
Note:
Even though you cannot edit a locked pro-
gram, you can still see the settings in Program
Review.
AOP1 / Auxiliary Output
Select Vent Fan or Alarm for the Auxiliary Output
The
[AOP1]
(Auxiliary Output) is for a receptacle
(called a socket in England) mounted on the kiln switch
box. The outlet can power a kiln vent or an external alarm,
such as a bell. (An AOP outlet is optional and might not be
included on your kiln.)
The choices in the
[AOP1]
option:
I
[VFAN]
Kiln Vent or Gas Outlet:
This option adds a
display prompt for fan (
[ FN]
) to each segment during
Ramp-Hold programming, page 13.
I
[NONE]
None:
Use this setting if your kiln does not
have the AOP outlet.
I
[SAFE]
This is for an optional safety relay and is used
with the
[LIM]
option. In
[LIM]
, program the maximum
temperature that you want for your kiln. If the kiln is 1
degree hotter than that temperature, the kiln will shut
off. See page 19.

ELEC / Electronics Temperature
Check the Circuit Board Temperature
High temperatures in the switch box can damage the
controller circuit board, which is rated for 176°F / 80°C
maximum operating temperature. To lower the board tem-
perature, use a fan to blow air across the kiln switch box into
the ventilation slots. (But do not blow air into the kiln’s
peepholes.) When firing several kilns, position them at
least three feet apart to allow adequate air circulation.

Press
Start/Stop
to return to the normal display.
Do not operate the kiln if the ELEC display is above
158°F / 70°C.
RATE / Select Preferred Type of Rate
Choose 1) Rate Per Hour, 2) Rate Per Minute, or 3)
Elapsed Time to Temperature
Rate is how fast the kiln heats or cools. Rate as degrees
of temperature change per hour is the most widely used
rate system in America.
Some brands of controllers, though, measure the rate as
an amount of time needed to reach a temperature. If you
are accustomed to that type of programming, you can con-
tinue to program with that method. Change the type of rate
in the
[RATE]
option of your Sentry Xpress controller to
the
[TIME]
setting. You then won’t have to change your fir-
ing schedules to degrees per hour rate.
