AOP Outlet (AOP)

Select Vent Fan or Alarm for the Auxiliary Output
The optional "AOP" (Auxiliary Output) is an electrical
receptacle 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 on your kiln.
The choices in the AOP option:
Alarm: This choice sends power to the AOP re-
I ALAR
ceptacle whenever the alarm sounds. (See Alarm, pages 6
& 7.) Plug in a loud bell to alert you, from a distance, that
the kiln has reached the alarm temperature.
None: Use this setting if your kiln does not have

Computer ID (ID)

Enter an ID Number for Connection to a Computer
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 and 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 a ramp, the set point changes at
the rate you programmed. During a hold, the set point re-
mains steady. The Sentry shows error messages when it
can't maintain the set point. The cushion, or leeway, allowed
before an error message flashes is called Temperature Devi-
ation. When the temperature is off by more than the Tem-
perature Deviation setting, the alarm sounds. Temperature
Deviation affects these error messages (see page 22):
Fail to Heat
FTH
Fail to Cool
FTC
High Temperature Deviation
HTDE
Low Temperature Deviation
LTDE
To turn these error codes off, enter a Temperature Devi-
ation of 0.

CAUTION: The High Temperature Deviation
(HTDE) alarm shuts off the kiln to prevent an
overfire. Entering a temperature deviation of 0
shuts off this important alarm! Programming a fir-
ing at FULL rate (1799°F/999°C or higher rate) will
also shut off the deviation alarms for that firing.

Electronics Temperature (ELEC)
Check the Circuit Board Temperature
High temperatures in the switch box can damage the con-
troller circuit board, which is rated for 158°F/70°C maxi-
mum operating temperature. If necessary, exhaust hot air
from the room to lower board temperature.When firing sev-
eral kilns, position them at least three feet apart to allow ade-
quate air circulation.

Program Lock (LOCK)

Make a Program Tamper-Proof
With Program Lock activated, a stored program cannot be
altered or removed from memory. Use Program Lock for re-
peat firings that you don't want to inadvertently change.
Note: Program Lock does not save a Delay setting.
While a program is locked, you can enter a new
Delay.
