Note 1: It is good practice to check that the program is correct by pressing the g key &
checking the program number & program contents before pressing the j 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.
Note 2: During ramping the ST 410 will perform either controlled heating or controlled cooling - as
indicated on the mimic display. During soaking the ST 410 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.
Information: The ST 410 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 ST 410 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 indi-
cator will remain lit. If full cooling is required the kiln heating indicator will remain off.
