Sentry Xpress 5 Cone-Fire / Ramp-Hold

28

Do not leave your kiln unattended during operation.

Display Messages

[ABRT]

Abort

10, 13

The firing was stopped.

[ALAR]

Alarm

5, 7, 14, 15, 18, 20, 22

ALAR appears either when you are entering an alarm temperature
or when the alarm is sounding during a firing. To stop an alarm,
press the Down Arrow key. If the alarm goes off when you first begin
firing, it is because it was set for a lower temperature than the pres-
ent temperature.

[AOP1]

Auxiliary Output

11, 13, 14, 19, 22

The AOP1 option is for kilns equipped with a special-order kiln
switch box receptacle called the Auxiliary Output.

[BADP]

Bad Programming

25

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

20, 23

Enter the electric rate shown on your electric bill. Example: 9.25
cents per KWh is entered as 00.09.

[CFG]

Configuration Code 24

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

8-11

The Sentry Xpress is ready for you to enter a cone number.

[COOL]

Slow Cooling

2, 10, 11, 17

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, 10, 13

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

19

Check the amperage. Test the relays.

[DELA]

Delay

2, 5, 6, 10, 13, 17, 21

DELA is a timer that starts the kiln later. Delay time appears in hours
and minutes. You can turn off the DELA prompt in Options.

[ELEC]

Electronics Temperature 22

The Sentry Xpress circuit board is rated for operation at tempera-
tures up to 176

°

F / 80

°

C. When the circuit board gets hotter, the

Sentry Xpress shuts off. The ELEC option shows you the tempera-
ture of the circuit board.

[ETH]

Electronics Too Hot 22, 25

The Sentry Xpress circuit board is too hot, so the kiln shut off.

[F / C]

Change °F / °C

19

Choose between operation in degrees F or degrees C.

Message Definition

Page Reference

[°F 1]

or

[°C 1]

Target Temperature 13

This prompt, which appears in Ramp-Hold programming, is asking
for a target temperature. The number is the segment of the pro-
gram.

[FAIL]

Thermocouple Failed 25

The thermocouple failed. This can be due to a broken thermocou-
ple, loose thermocouple connection on the back of the Sentry
Xpress, disconnected thermocouple wire, or a defective controller.

[FAST]

Fast Speed

10

In Cone-Fire programming, if you press Start/Stop when FAST ap-
pears, the kiln will program to fire at fast speed.

[FE 1]

&

[FE 4]

Failed Component 26

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

13

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. See also AOP1, left column.

[FTC]

Failed to Cool

20, 25

This error message means the kiln cannot cool as fast as the cool-
ing that you programmed.

[FTH]

Failed to Heat

20, 21, 25

The kiln cannot heat as fast as you programmed.

[FTL]

Firing Too Long

25, 26

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

13, 14, 15, 21, 23, 25, 26

This rate, or temperature change per hour, is maximum.

[HD 1]

Temperature Hold

13

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 14, 21, 25, 26

During a heating-up ramp or a hold, the temperature is 100°F /
56°C above the programmed temperature.

[IDLE]

Ready to Begin

Cover, 5, 10, 13

The Sentry Xpress must display the IDLE message before you can
begin firing or programming.
