AOP Outlet (AOP)

Select Vent Fan or Alarm for the Auxiliary Output
The optional AOP (Auxiliary Output) is an electrical re-
ceptacle mounted in the kiln's switch box. This outlet can
power a kiln vent or an external alarm, such as a bell. The
AOP is a special-order option that might not be included on
your kiln.
The choices in the AOP option:
This choice sends power to the AOP re-
ceptacle whenever the alarm sounds. (See Alarm, page
11.) Plug in a loud bell to alert you, from a distance, that
the kiln has reached the alarm temperature.
Use this setting if your kiln does not have
the AOP outlet.
Do not use FAN2.
This option adds a prompt for fan
( ) to each segment during programming (page 7).

This feature is for assigning an identification number,
from 1 to 15, to the controller. It is used only for hookup to a
personal computer, which requires an optional kit.

Temperature Deviation
(TEDE)
Adjust Temperature Sensitivity of Error Codes
The ideal temperature of a firing, at any given time, is
called the set point. During heating or cooling, the set point
changes at the rate you programmed. During a hold, the set
point remains steady.
The Sentry shows error messages when it can't maintain
the set point. The cushion, or leeway, allowed before an er-
ror message flashes is called Temperature Deviation.
When the temperature is off by more than the Temperature

Some people worry when
pears. They wonder if something is wrong with the kiln.
Here are the methods to set the deviation temperature so
the alarm messages do not appear during routine firings:
Test your kiln to find its fastest firing rate and
its slowest cooling rate. Then program the controller using
rates within the range of the kiln's heating/cooling capacity.
If your fastest heating rate is 600° per hour, enter a rate no
faster than 600°.
number in the TEDE Option. The higher the number, the
less likely that an alarm message will appear.
TEDE Option. Note, however, that this turns off the
HTDE alarm (page 18). We do not recommend a 0 setting.
This will shut off the deviation alarms for that segment.
(However, deviation alarms will continue to work during
the hold and all other segments with slower rates.)
CAUTION:
(HTDE) alarm shuts off the kiln to prevent an overfire.
Entering a temperature deviation of 0 turns off this im-
portant alarm! Entering a FULL rate also turns off this
alarm for the segment with the FULL rate!
