Configuration Code (CFG)

Information for Technicians

From IdLE , press OPTIONSrepeatedly until CFG ap- pears. Press ENTER. The factory configuration code will ap- pear. Press ENTER. Press STOP to return to IdLE . The configuration code can be changed only at the factory.

Software Version (SOFT)

Information for Technicians

From IdLE , press OPTIONSrepeatedly until SOFT ap- pears. Press ENTER. The software version will appear. Press ENTER. Press STOP to return to IdLE . The software ver- sion can be changed only at the factory.

Element Test (TEST)

Test the Heating Elements and Relays

This test is useful when measuring the wall receptacle voltage under load, and amperage with an ammeter. On a multiple zone kiln, the test helps determine if the relays and thermocouples are wired to the correct zones. If you test thermocouples with a lighter or other heat source, use the Test option.

Single Zone Kiln

1From IdLE , press OPTIONSrepeatedly until TEST appears.

2Press ENTER. POWR will appear, alternating with kiln temperature. The elements will turn on for 2 minutes. Press any key to abort the test.

Multiple Zone Kiln

1From IdLE , press OPTIONSrepeatedly until TEST appears.

2Press ENTER. TOP will appear, alternating with the temperature of the top zone. The elements will

turn on for 2 minutes. Then MID will appear, with temperature for the middle zone, and BOT with temperature for the bottom zone. (A 2 zone kiln shows TOP and BOT displays only.)

3During the 2 minute test, press any key to end a zone test. The controller will then begin to test the next zone.

AOP Outlet

After the above tests, kilns equipped with the AOP outlet will display J3-3for 2 minutes to test power to the AOP outlet.

Reset (RST)

Reset the Controller to Most Factory Defaults: Perform Only When Requested by a Technician

Reset does the following:

■Selects Type-S thermocouple

■Selects °F

■Erases Cone offsets

■Erases Thermocouple offset

■Erases user programs in Ramp-Hold

CAUTION: If your kiln uses a Type-K thermocou- ple, the Sentry will underfire after a reset! Use the Thermocouple Option (page 19) to select Type-K again.

1From IdLE , press OPTIONSrepeatedly until RST appears.

2 Press ENTER. Use the 1 or 2 key to select NO or YES .

3After selecting one of the above, press ENTER. Press STOP to return to IdLE .

Multiple Zone Options

These options appear only on multiple zone kilns.

Zone Temperature Difference (DIFF)

View Maximum Temperature Spread

For a 2 zone kiln, this option shows temperature differ- ence between the zones. For a 3 zone kiln, it shows the high- est temperature difference between any two zones. If the temperature shown is larger than expected, go to option T 123 to view the temperature of each zone.

1 Press OPTIONS repeatedly until DIFF appears. Press ENTER.

3The maximum difference in temperature between any zones displays. (Example: -003 .)

Two Zone Kilns: Adjust Heat in Center Section (CAdJ)

The Center Adjust option appears only on 2 zone kilns that contain 3 relays and 3 banks of elements. It does not ap- pear on 2 zone kilns with 2 relays, or on 3 zone. The Center Adjust acts as an infinite control switch that adjusts heat to the center section of the kiln. A number will display. 100 is the factory default, meaning 100% heat. You can change the setting from 0 to 200. The higher the number, the more the heat in the center section.

1From IdLE , press OPTIONSrepeatedly until CAdJ appears.

2Press ENTER. Use any number key to change the number that appears.

3Press ENTER. Press STOP to return to IdLE .

Zone Temperatures (T123)

View Temperature of Each Zone

1 Press OPTIONS repeatedly until T123 appears. Press ENTER.

3The temperature for each zone will display one after the other, cycling for one minute. Then normal tem- perature display will return. For example:

■ Top zone: TC 1¯ 1250

■

Middle zone:

TC 2-

 

1251

 

 

Bottom zone:
