The TC40 combines very easy handling, safe and precise kiln operation at a very reasonable price. Before operating the TC40, please read and understand the manual carefully. [. . . ] Use the keys (4) and (6) to change this value to 120°C/h (as our example). Use the keys (4) and (6) to enter the requred final temperature of the firing (800°C as our example). If you hold the key (4) or (6) pressed, the displayed value will run through automatically. k k k resp. resp. resp. o o o o o o Press the key (3) to step to the next segment of the curve (section c. ). 10 minutes). Instead of a linear heat up (section a. ) you can also enter an uncontrolled heat up, ie. The value SKIP is shown as depicted left. 10 If you want to change a value again or you have skipped a segment unintentionally, use the key (3) to get back to the beginning of the firing curve. Additionally, the firing curve (2) indicates the current section of the firing. The flashing decimal point in the right hand corner indicates programme running. start stop Checking the Programme Values To check or change the values of a programme when the firing has already been started, proceed as follows: Press the key (3), the firing is interrupted automatically (decimal point stops flashing). Now, you can step through the segments using the key (3) as described before. To continue the firing with the new values press key (5) again. Reaction on Power Breakdown For security reasons the firing will be interrupted if a power breakdown occurs. For special applications a version with power breakdown restart feature is available on request.

In case of any malfunction the display will show an error message pointing to the problem. Following is a description of the possible error messages: The kiln doesn´t follow the required temperature increase. Possible cause: · broken fuse, power phase or relay failed · the door (lid) contact is open · a heating element is broken · the heating elements are too old (esp. with high firing temperatures) · the thermocouple has a short circuit Thermocouple or thermocouple circuit defect Possible cause: · thermocouple broken · thermocouple wiring bad · contacts of the connecting plug bad Impossible values on data acquisition Possible cause: · thermocouple polarized bad · thermocouple temperature less than -15°C Safety Switch Off features was activated The TC60 has measured an overtemperature in the kiln and switched off the kiln by the 2nd power relay (if fitted). Check carefully the cause before using the kiln again to avoid further damage !Ask your dealer for assistance. 12 Error detected during power-up self check On every power-up the controller performs a self check. If an error is detected the controller shows F8 (ROM error) or F9 (hardware error).
