Page 6: Programming
(target temperature) Heating Ramp An ST535 firing segment comprises a ramp followed by a soak period. Two seg- ments can be used for simple firing (biscuit firing for example) or several seg- ments can be used per program for complex firing (crystal glazing or glass- making for example). - Page 7 Note 2: to exit programming without cycling through all of the above steps wait 20 seconds without pressing any keys - the ST535 will revert to the idle display. Alternatively press the ►n key to exit programming and to begin firing immediately.

Page 8: Temperature Display
Zone 1 is displayed by default when the ST325 is powered on. To change the displayed zone press either the 1018°C ▲ or ▼ keys. The zone number icons will change to show which zone temperature is be- ing displayed. Page ST535 User Handbook... -
Page 9: Firing
ST535 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 10: 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 ST535 back to idle condition ready for the next firing press the ►n key (or turn off the power to the instrument). -
Page 11: Operating Notes
Operating Notes Kiln too slow If the ST535 is programmed to heat the kiln at a faster rate than the kiln is capable of then the ST535 will turn on full power then wait until the kiln tem- perature has risen to the correct temperature before proceeding to the next ramp or soak segment. -
Page 12: Adjusting While Firing
The effect of this is as follows:- If ramping then the ST535 will switch to soak at the current kiln temperature. If soaking then the ST535 will advance to the next segment if any, or else it will end the firing. -
Page 13: Error Messages
Error Messages If the ST535 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 14 All these error messages cause the ST535 to terminate the firing. The alarm buzzer will sound once per second. To reset the ST535 turn off the power to the instrument and have the fault investigated and rectified by your installer or kiln service engineer.

ST535 is currently trying to achieve). Keyboard Lock Facility The keys on the ST535 can be locked so that pressing them has no effect. This is an anti-tamper feature used to ensure that the operation of the ST535 or the program data cannot be altered by un-authorised people. -
Page 16: Control Relay
Control Relay Control Relay Configuration The ST535 has a relay output that can be configured (see installation instructions) as an event output, a damper control output, a fan control output or not used. Event Output The event relay can be programmed to change state at the start of a ramp and also at the start of a soak period. - Page 17 (firing indicator not lit). Note: in the sequence below if no key presses are detected within 30 seconds the ST535 will exit the menu and damper temperature changes will not be saved. The damper close temperature prompt is DAMPER:C shown.
- Page 18 (firing indica- tor not lit). Note: in the sequence below if no key presses are detected within 30 seconds the ST535 will exit the menu and fan temperature changes will not be saved. The fan start temperature prompt is FAN: ON shown.
