AppendixA:
Display Messages
[ABRT]
Abort
6
The firing was stopped.
[ALAR]
Alarm
6, 8, 9, 11, 15
ALAR appears either when you are entering an alarm temperature
or when the alarm is sounding during a firing. To stop an alarm,
press any key except STOP. If the alarm goes off when you first be-
gin firing, it is because it was set for a lower temperature than the
present temperature.
[AOP1] [AOP2]
Auxiliary Output 2, 13, 16, 21- 23, 25
The AOP option is for kilns equipped with a special-order kiln
switch box receptacle called the Auxiliary Output.
[BADP]
Bad Programming
27
This message appears when a Ramp-Hold firing has been pro-
grammed with 0 rate in the first segment or when all target temper-
atures are lower than the current kiln temperature.
[CENT]
Electrical Rate
8, 23
Enter the electric rate shown on your electric bill. Example: 9.25
cents per KWh is entered as 00.09.
[CFG]
Configuration Code 2, 26
This is an option that shows the factory configuration code for your
Sentry. This is for technicians who call the factory for support.
[CONE]
Cone-Fire
11
The Sentry is ready for you to enter a cone number.
[COOL]
Slow Cooling
11, 13, 21
In Cone-Fire programming, Slow Cooling is shown as COOL. To
program a slow cooling, enter the cooling rate in degrees per hour.
Leave the setting at 0 if you do not want a slow cooling.
[CPLT]
Completed Firing
6, 9, 11, 15, 24
This means the firing completed normally as programmed. These
three messages will also cycle one after the other: firing time in
hours and minutes, the temperature of the last segment, and the
current kiln temperature.
[DIAG]
Amperage Check
21
Check the amperage that your kiln is drawing.
[DELA]
Delay
7, 11, 15
DELA is a timer that starts the kiln later. Delay time appears in hours
and minutes.
[DIFF]
Temperature Difference 26
This option shows the maximum temperature spread between
zones in a multiple zone kiln.
[ELEC]
Electronics Temperature 25
The Sentry circuit board is rated for operation at temperatures up to
176
°
F / 80
°
C. When the circuit board gets hotter, the Sentry shuts
off. The ELEC option shows you the temperature of the circuit
board.
[ETH]
Electronics Too Hot 27, 28
The Sentry circuit board is too hot, so the kiln shut off.
[F / C]
Change °F / °C
22
Choose between operation in degrees F or degrees C.

[°F 1]
or
[°C 1]
Target Temperature 15
This prompt, which appears in Ramp-Hold programming, is asking
for a target temperature. The number is the segment of the pro-
gram.
[F 20]
Fast Speed
20
Cone-Fire fast speed shows in Program Review as F 20. This is
also how Fast Speed is listed in the SPD Speed option.
[FAIL]
Thermocouple Failed 28
The thermocouple failed. This can be due to a broken thermocou-
ple, loose thermocouple connection on the back of the Sentry, dis-
connected thermocouple wire, or a defective controller.
[FAN]
Vent Fan
13, 16, 21
The Fan option, accessed through the OPTIONS key, is for kilns
equipped with a special-order kiln switch box receptacle called the
Auxiliary Output.
[FAST]
Fast Speed
11
In Cone-Fire programming, if you press ENTER when FAST ap-
pears, the kiln will program to fire at fast speed.
[FE 1]
&
[FE 4]
Failed Component 28
These codes may mean a circuit board component has failed. But
sometimes the problem can be cleared by turning the power off
and restarting the controller.
[FN 1]
Fan
15, 16, 22
If your kiln has the optional AOP outlet (for a kiln vent), the FN
prompt will appear for each segment during Ramp-Hold
programming. It is asking if you want the vent on or off for that seg-
ment.
[FTC]
Failed to Cool
24, 27
This error message means the kiln cannot cool as fast as the cool-
ing that you programmed.
[FTH]
Failed to Heat
24, 27
The kiln cannot heat as fast as you programmed.
[FTL]
Firing Too Long
27, 28
The temperature rise is less than 27
°
/ 15
°
C per hour and the firing
time is two hours longer than the current segment was pro-
grammed.
[FULL]
Full Speed
16, 18, 24, 27, 28
The rate, or temperature change per hour, is maximum.
[HD 1]
Temperature Hold
15, 16
When this message appears during Ramp-Hold programming, it is
asking you if you want to hold, or maintain, the target temperature
of that segment. If so, enter the length of hold time in hours and
minutes (i.e. 1 hour 20 minutes = 01.20). The number after HD is
the segment number.
[HOLD]
Temperature Hold
11, 13
When this message appears during Cone-Fire programming, it is
asking you if you want to hold, or maintain, the cone temperature at
the end of the firing. If so, enter the length of hold time in hours and
minutes (i.e. 1 hour 20 minutes = 01.20).
[HTDE]
High Temperature Deviation 16, 24, 27, 28
During a heating-up ramp or a hold, the temperature is 100°F /
56°C above the programmed temperature.
