Firing
To start a firing press the ► key. The firing indicator lamp will flash.
Hint: it is good practice to check that the program is correct by press-
ing the ► key & checking the program number & program contents
before pressing the ► key to start a firing. It is also a good idea to
have a written record of the contents of the firing programs kept and
displayed near the kiln especially if there is more than one user of the
kiln.
With the firing indicator flashing an optional
start delay up to 99 hours: 59 minutes can
be entered with the ▲ & ▼ keys.
Information: The ST535C operates by calculating the amount of energy required by
the kiln every 30 seconds (installer adjustable). If for example 40% of full energy is
required to maintain a particular ramp rate or a particular soak temperature then the
ST535C will apply heating power to the kiln for 12 seconds every 30 seconds. The
kiln heating indicator will light for 12 seconds every 30 seconds. If the kiln has a
contactor then a loud click will be heard both when the kiln heating indicator lights up
and when it goes out. If full heating power is required then the kiln heating indicator
will remain lit. If full cooling is required the kiln heating indicator will remain off.
After 10 seconds, or immediately if the ► key is pressed again, the firing
will commence and the firing indicator lamp will remain lit.
To stop the firing prematurely at any time press the ► key again. The firing
indicator lamp will go out.
Note: during ramping the ST535C will perform either controlled heating or
controlled cooling - as indicated on the mimic display. During soaking the
ST535C display alternates every 15 seconds between kiln temperature and
soak period remaining. At the end of each segment the segment number
display will be incremented.
