Present Status; The Alarm; Skip Segment; Editing A Segment During Firing - Orton Sentry 2.0 Operating Instructions Manual

Present Status

Press during a firing to display the
current segment that is firing. Either of
the following messages will appear in
Present Status:
Ramp and segment number: The Sentry is in the
ramp part of a segment. See chart, page 6.
Hold and segment number: The Sentry is in the
hold part of a segment.
Present Status is useful when firing a program that con-
tains heating and cooling segments. Without Present Sta-
tus, it might be easy to lose track of which segment is firing.

The Alarm

The alarm sounds when the kiln
reaches the alarm temperature you enter.
Use the alarm to alert you to check the
fusing or slumping of glass or remove a knife blade from the
furnace at the end of heat treating.
You can enter only one
alarm temperature at a time.
However, after the alarm
beeps, you can set the alarm
for another temperature, as
many times as you want,
during the firing. Entering
an alarm temperature auto-
matically erases the previ-
ous alarm temperature.
Monitoring the Alarm
from a Distance
Place an inexpensive
baby monitor near the kiln.
From another location in your building, you will be able to
hear the digital temperature alarm. You will also hear the
clicking of the relays, which would indicate that the temper-
ature is still rising in the kiln.

for controlled cooling. Watching the glass through the
peephole, you notice that the glass edges have rounded
nicely. Use Skip Segment to end the firing segment and
begin the one for slow cooling.
Note: Make a note of the temperature at which the
glass fused. Program that temperature for the next fir-
ing of that type of glass.
