ST315B’s serial number. Next displayed is the thermocouple type to which the ST315B is set. This thermocouple type setting should match the type of thermocouple fitted to the kiln and can be R, S, K or N type. -
Page 6: Programming
9 segments can be used per program for complex firing (crystal glaz- ing or glass-making for example). The ST315B ramps the kiln temperature at the required ramp rate until the kiln reaches the soak temperature. It then soaks (dwells) at the soak tem- perature for the soak time. - Page 7 Altering a program When the ST315B is not firing there are no lamps lit on the mimic panel, the run lamp is off and the display shows the kiln temperature with the °C indicator lit.

When the kiln has cooled to less than 40°C the display alternates every 5 seconds between the kiln temperature and To return the ST315B back to idle condition ready for the next firing press the START/STOP key (or turn off the power to the instrument). -
Page 14: Adjusting While Firing
Adjusting While Firing Firing values can be adjusted while the ST315B is firing. Also there are program pause/un-pause and segment advance features that are particular- ly useful for glass work. Adjusting Firing Values While firing operate the key to select the required parameter as shown by a flashing lamp on the mimic display. - Page 15 This will advance the segment and will immedi- ately terminate a paused soak - advancing to the next segment (if any). Changes made to the operation of the ST315B in this way are temporary and are not stored.

SWITCH KILN OFF! To reset the ST315B turn off the power to the instrument and have the fault investigated by your installer or kiln service engineer to rectify the fault. Note: these error messages are provided to detect kiln faults and so offer some protection to the kiln.
