AOP1, AOP2 /Auxiliary Outlets

Select Vent Fan or Alarm for the Auxiliary Outputs

The optional AOP1 and AOP2 (Auxiliary Outputs) are

for electrical receptacles mounted in the kiln’s switch box.

alarm, such as a bell. (The AOP outlet is a special-order

option that might not be included on your kiln.)

The choices in the AOP1 and AOP2 options:

This choice sends power to the AOP re

ceptacle whenever the alarm sounds. (See Tempera

ture Alarm, page 12.) Plug in a loud bell to alert you,

from a distance, that the kiln has reached the alarm

temperature. (Controllers with pre-20A software: Se-

lect .)

Use this setting if your kiln does not

have the AOP outlet.

This option adds a

prompt for fan ( ) to each segment during pro-

RATE/TypesofRates

Note: This feature is included on controllers with

software version 18D or newer. To look up your soft

ware version, see the SOFT option, page 18.

The standard method of programming firing rate is

degrees of temperature change per HOUR. At the factory,

wecan set up yourcontroller to calculate rate insteadas de

grees of temperature change per MINUTE, or as

ELAPSED TIME needed to reach a temperature. The

RATE option shows you which method your controller

uses:

From ,press repeatedly until

appears.

Press . You will see one of the following:

(Degrees of temperature change per hour)

(Degrees of temperature change per minute)

(Elapsed time needed to reach a temperature)

Only the factory can change the type of rate used in your

controller.

Note: If your controller uses TIME rate, enter the

hours/minutes that each segment will take to reach its

target temperature. (Example: 1 hour, 30 minutes =

01.30.)

COST / Electric Cost Per

Kilowatt-Hour

Note: This feature is included on controllers with

software version 18D or newer. To look up your soft

ware version, see the SOFT option, page 18.

The controller can figure the cost of a firing if you enter

the cost of electricity for your area (and kiln wattage—see

next option). The cost of electricity is figured in kilo

watt-hours (KWh). A kilowatt-hour is 1,000 watts of elec

tricity running for 1 hour. (10 – 100-watt light bulbs glow

ing for one hour consume 1 KWh of electricity.)

To find what the power company charges you for a kilo-

watt-hour, look at your electric bill, call your power com-

pany, or visit their website. The electric rate may vary de-

pending on the time of year and amount of electricity you

use. In the summer, rates in some areas are higher. Also,

add the other costs listed on your electric bill, such as

power transmission charges, taxes, etc.

From ,press repeatedly until

appears. Press .

From an electric bill, enter the cost of a kilo

watt-hour. Place cents to the right of the decimal.

Round off fractions. (Example: Enter 9.25 cents

per kilowatt-hour as 00.09.) Press

Press to return to .

Note: You can enter the cost in U. S., Canadian, or

Euro cents, British pence, Indian paisas, or any other

money system that is based upon 100 units (i.e. 100

cents = 1 dollar.) If your system is based upon 1000

units, such as the Libyan dirham, the Oman baiza, or

the Kuwait fil, divide the cost by 10. Example: Enter

140 as 00.14. Then multiply by 10 the cost of a firing

shown in the controller display.

KW / Kilowatts Used to

Calculate Firing Cost

Note: This feature is included on controllers with

software version 18D or newer. To look up your soft

ware version, see the SOFT option, page 18.

To figure the cost to fire your kiln, the controller needs

to know how many kilowatts your kiln uses. Look at your
