(crystal glazing or glass- making for example). The ST535C ramps the kiln temperature at the required ramp rate until the kiln reaches the soak / target temperature. It then soaks (dwells) at the soak temper- ature for the soak period. - Page 8 Note 2: to exit programming without cycling through all of the above steps wait 20 seconds without pressing any keys - the ST535C will revert to the idle display. Alternatively press the ► key to exit programming and to begin firing immediately.

Control Relays Control Relay Configuration The ST535C has 2 control relay outputs. Control relay 1 can be configured as an event output, a damper control output or a fan control output. Control relay 2 can be configured as an event output only. - Page 10 (firing indicator not lit). Note: in the sequence below if no key presses are detected within 30 seconds the ST535C will exit the menu and damper temperature chang- es will not be saved. The damper close temperature prompt is DAMPER:C shown.
- Page 11 (firing indica- tor not lit). Note: in the sequence below if no key presses are detected within 30 seconds the ST535C will exit the menu and fan temperature changes will not be saved. The fan start temperature prompt is shown.

Page 12: Firing
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. -
Page 13: Cooling
When the kiln has cooled to less than 40°C the display alternates every 5 seconds between the kiln temperature and END. To return the ST535C back to idle condition ready for the next firing press the ► key (or turn off the power to the instrument). -
Page 14: Operating Notes
Operating Notes Kiln too slow If the ST535C is programmed to heat the kiln at a faster rate than the kiln is capable of then the ST535C will turn on full power then wait until the kiln temperature has risen to the correct temperature before proceeding to the next ramp or soak segment. -
Page 15: Adjusting While Firing
The effect of this is as follows:- If ramping then the ST535C will switch to soak at the current kiln temperature. If soaking then the ST535C will advance to the next segment if any, or else it will end the firing. -
Page 16: Error Messages
Error Messages If the ST535C detects a problem the buzzer will sound and an error message will be displayed. This error message will alternate with a display of kiln temperature. The segment number display will show where the error occurred. - Page 17 All these error messages cause the ST535C to terminate the firing. The alarm buzzer will sound once per second. To reset the ST535C turn off the power to the instrument and have the fault investigated and rectified by your installer or kiln service engineer.

This instrument is designed for use mainly in Domestic, Commercial & Light Industrial environments where electromagnetic interference may cause a loss of accuracy of the displayed temperature reading of up to 3°C. Specified accuracy will be restored when the interference is removed.
