Keep the kiln lid or door closed when the kiln is not in use. 29
[KW] Kilowatts 19, 23
The controller can figure the cost to fire your kiln if you supply your
kiln’s wattage. (See the data plate on the switch box.) Divide watt
-
age by 1000 to get kilowatts. 10,800 watts ÷ 1000 = 10.8.
[LID] Lid/Door is Open 6, 28
When LID appears, either a lid or door switch is out of adjustment or
a two-pin connector on the back of the board is missing.
[LOCK] Program Lock 10, 13, 21
With this option activated, a stored program cannot be altered or
removed from memory.
[LTDE] Low Temperature Deviation 20, 25
This message appears when the kiln is below the Temperature De
-
viation setting in the TEdE option.
[OFST] Cone Offset 16, 20
Adjust a Cone-Fire program to bend the matching witness cone on
the kiln shelf.
[-ON-] Firing Started 6, 10, 13
This appears when firing begins. Do not be concerned if it takes a
moment for the relays to turn on. The Sentry Xpress is processing
data.
[OTL] Over Temperature Limit 19, 27
This means the kiln has fired hotter than the temperature set in the
LIM option. It takes only a moment to reset the option.
[PF 1] Power Failure 27
The power failed during a controlled cooling segment. The kiln
temperature was below the last active cooling segment tempera-
ture when the power came back on.
[PF 2] Power Failure 27
The power failed. When power came back on, the temperature was
below 212°F / 100°C.
[PF 3] Power Failure 27
The power failed and the temperature dropped 72°F/ 40°C.
[PF] Power Failure 27
There was a power failure during firing. The kiln continued firing af
-
ter the power came back on.
[RA 1] Rate 13
RA 1, RA 2, RA 3, etc., appear in Ramp-Hold programming, Pro
-
gram Review, and Present Status. When RA 1, 2, 3, etc. appear
during programming, the controller is asking you for firing rate for
each segment. Rate means how fast the firing progresses, in de
-
grees of temperature per hour. Every segment must have a firing
rate. The number after RA is the segment number.
[RST] Reset 17, 18, 21, 24
The RST option erases cone and thermocouple offsets, selects °F
operation, erases stored programs in Ramp-Hold, and selects
S-Type thermocouple. Note that if you use Reset, and your kiln is
equipped with a K-Type thermocouple, you must use the TC option
to select K-Type. (Reset selects S-Type as a safety precaution. If
you had a S-Type thermocouple and Reset selected K-Type, your
kiln would overfire. On the other hand, if you had a K-Type thermo
-
couple, S-Type selected would underfire your kiln, which is better
than overfiring it. The K-Type thermocouple is on most kilns.)

[SFTY] Safety 24
This is the maximum temperature the Sentry Xpress is pro
-
grammed for your kiln. It can be altered only at the factory.
[SKIP] Skip Segment 10, 13, 15, 16
If you press the Skip Segment key during a firing, SKIP will appear.
If you press the key again, the firing will skip to the next segment. In
Cone-Fire, Skip Segment takes you only out of Pre-Heat or Hold.
[SLOW] Slow Speed 2, 10, 11, 15, 17, 20
In Cone-Fire programming, if you press Start/Stop when SLOW ap
-
pears, the kiln will program to fire at slow speed.
[SOFT] Software Version 24
This option gives the version of software in your Sentry Xpress.
[SPD] Speed 10
The SPD message appears during Cone-Fire programming and in
Options. 1) In the SPD option, accessed through the option key,
change the speed of a Cone-Fire program beyond the standard
fast, medium or slow. 2) While programming a firing for Cone-Fire,
choose slow, medium or fast speed at the SPD prompt.
[STD] Standard Speed 10
Cone-Fire medium speed appears in the Sentry Xpress as STD, or
Standard. This is because medium speed is the standard firing
program used in Cone-Fire.
[TC] Thermocouple Type 11, 18, 24
Choose between types K, S, or R thermocouple. It is important to
select the correct type, or the controller will not read temperature
accurately.
[TCOS] Thermocouple Offset 17, 20
Adjust the controller’s temperature to compensate for temperature
drift, or aging, of a thermocouple.
[TCR] Thermocouple Reversed 27
Thethermocouplewiresarereversed.
[TEDE] Temperature Deviation 14, 15, 20, 21, 24, 25
The Sentry Xpress includes error messages to warn you that the
kiln is not maintaining the programmed temperature. The sensitiv
-
ity of the error messages is based on a temperature in TEDE.
[TEST] Element Test 19
This option is for testing the elements and thermocouples. If you
test a thermocouple with a lighter, the temperature display re
-
sponds faster during Test than at IDLE display.
[USER] User Program 10, 13, 24
In Ramp-Hold programming, the USER prompt is asking you
where you want to place the program in memory. The Sentry
Xpress has 9 spaces in memory. Keep a written record of the pro
-
grams 1 - 9 in memory.
