Appendix A: Display Messages

Abort 5

The firing was stopped.

Alarm 8, 10, 11, 12

ALAR appears either when you are entering an alarm tem

perature 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 begin firing, it is because it was set for a

lower temperature than the present temperature.

Auxiliary Output 8, 10, 16

The AOP option is for kilns equipped with a special-order kiln

switch box receptacle called the Auxiliary Output.

Bad Programming 20

This message appears when a firing has been programmed

with 0 rate in the first segment or when all target tempera

tures are lower than the current kiln temperature.

Configuration Code 18

This is an option that shows the factory configuration code

for your Sentry. This is for technicians who call the factory for

support.

Change °F / °C 15

Choose between operation in degrees F or degrees C.

Electrical Rate 12, 16

Enter the electric rate shown on your electric bill. Example:

10.25 cents per KWh is entered as 10.25.

Completed Firing 5, 9

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.

Delay 8, 11

DELA is a timer that starts the kiln later. Delay time appears

in hours and minutes.

or Target Temperature 6

This prompt is asking for a target temperature. The number

is the segment of the program.

Temperature Difference 14

This option shows the maximum temperature spread be

tween zones in a multiple-zone kiln.

Electronics Temperature 18

The Sentry circuit board is rated for operation at tempera

tures up to 176°F/80°C. When the circuit board gets hotter,

the Sentry shuts off. The ELEC option shows you the temper

ature of the circuit board.

Message Definition Page Reference

Electronics Too Hot 20

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

Thermocouple Failed 5, 20

The thermocouple failed. This can be due to a broken ther

mocouple, loose thermocouple connection on the back of

the controller, disconnected thermocouple wire, or a defec

tive controller.

Vent Fan 16

The Fan option, accessed through the OPTIONS key, is for

kilns equipped with a special-order kiln switch box recepta

If your kiln has the optional AOP outlet (for a kiln vent), the FN

prompt will appear for each segment during programming.

It is asking if you want the vent on or off for that segment.

Failed to Cool 17, 19

This error message means the kiln cannot cool as fast as the

cooling that you programmed.

Failed to Heat 17, 19

The kiln cannot heat as fast as you programmed.

Firing Too Long 20

The temperature rise is less than 27° /15°C per hour and the

firing time is two hours longer than the current segment was

programmed.

Full Speed 7, 8, 17

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

Temperature Hold 8

When this message appears during programming, it is ask

ing you if you want to hold, or maintain, the target tempera

ture of that segment. If so, enter the length of hold time in

hours and minutes (Example: 1 hour 20 minutes = 01.20).

The number after Hd is the segment number. Each segment

in a firing is numbered.

High Temperature Deviation 17, 20

During a heating-up ramp or a hold, the temperature is

100°F / 56°C above the programmed temperature.

Computer ID 17

The ID option is for connecting the Sentry to a personal com

puter.

Ready to Begin 5

The Sentry must display the IdLE message before you can

begin firing or programming.
