the kiln.
Information: The ST315B 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 ST315B will apply heating power to the kiln for 12 seconds
every 30 seconds. The right
-
hand decimal point in the display will light for 12
seconds every 30 seconds. If the kiln has a contactor then a loud click will be
heard both when the decimal point lights up and when it goes out. If full
heating power is required then the decimal point will remain lit. If full cooling
is required then the decimal point will remain off.
