General Infrmatin Yur brand new bentrup TC40 represents ne f the mst ppular iln cntrllers f the cmpact class. The TC40 cmbines very easy handling, safe and precise iln peratin at a very reasnable price. Befre perating the TC40, please read and understand the manual carefully. This familiarizes yu with all functins f the TC40 quicly and ensures that yu can use all the capablities f yur cntrl. Security Advice Please refer t the security advice f the iln manufacturer. Mae sure that the cntrl is munted at a safe distance frm the iln and that the cntrl is nt expsed t direct heat r radiatin when the iln is pened whilst it is ht. Firing Curves The micrprcessr cntrller TC40 prvides yur iln with a precise and reprducable cntrlling unit. The firing curse is shwn as a firing curve cnsisting f five segments. An example is shwn belw. This firing curve cnsists f the fllwing sements: 900 580 [ C] a. heating up t 580 C at 120 C per hur b. heating up t 900 C at maximum pwer c. dwell (30 minutes) d. natural cling (a) (b) (c) (d) [min] Fr easier use, the TC40 has fixed values in the firing curve: The rate f heating up can be set t the values 60 C/h, 120 C/h, 240 C, 360 C/h, 480 C/h and maximum pwer. The temperature fr switching t maximum pwer is fixed at 580 C. The final temperature can be adjusted between 400 C and 1320 C in 5 C steps. The dwell can be selected 0, 10, 20, 30, 60 minutes. 9
Typical Firing Curves Depending n applicatin, clay, glaze etc. it required very different firing curves. Yur dealer will assist yu fr detailed questins. Fllwing firing curves are sme typical examples: Firing heatup( C/h) final temp. ( C) dwell biscuit 800 C 120 800 10 biscuit 900 C 120 900 10 glaze 1050 C 240 1050 30 stneware 1180 C 240 1180 30 stneware1250 C 240 1250 30 Entering a Firing Curve Example: The biscuit firing 800 C (refer t table shwn abve) is entered as a firing curve as fllws: resp. resp. resp. Pwer n the cntrller by the mains switch. After a few secnds the actual iln temperature appears n the display (1). Press the ey (3) nce. The sectin (a) f the firing curve (2) lights up. The display (1) shws the actual rate fr the heat up. Use the eys (4) and (6) t change this value t 120 C/h (as ur example). Press the ey (3) again t select the next segment (b). Use the eys (4) and (6) t enter the requred final temperature f the firing (800 C as ur example). If yu hld the ey (4) r (6) pressed, the displayed value will run thrugh autmatically. Press the ey (3) t step t the next segment f the curve (sectin c.). Adjust the dwell t the required value (e.g. 10 minutes). Instead f a linear heat up (sectin a.) yu can als enter an uncntrlled heat up, ie. with maximum pwer. This is dne by setting the firing curve t SKIP in the sectin a. The value SKIP is shwn as depicted left. 10
If yu want t change a value again r yu have sipped a segment unintentinally, use the ey (3) t get bac t the beginning f the firing curve. Yu can alter all values as ften as yu lie. start stp T start the firing, press the ey (5). The display (1) shws frm nw n always the iln temperature. Additinally, the firing curve (2) indicates the current sectin f the firing. The flashing decimal pint in the right hand crner indicates prgramme running. Checing the Prgramme Values T chec r change the values f a prgramme when the firing has already been started, prceed as fllws: Press the ey (3), the firing is interrupted autmatically (decimal pint stps flashing). Nw, yu can step thrugh the segments using the ey (3) as described befre. T change a value, use eys (4) and (6). T cntinue the firing with the new values press ey (5) again. Reactin n Pwer Breadwn Fr security reasns the firing will be interrupted if a pwer breadwn ccurs. Fr special applicatins a versin with pwer breadwn restart feature is available n request. Maximum Adjustable Values heat up...60 C t 480 C/h, SKIP end f heat up...580 C (fix, cnfigurable) final temperature...400 C t 1320 C* dwell...0.00 t 1.00 hurs * this value varies depending n the iln 11
Errr Messages The integrated micrprcessr inside yur TC60 perfrms cntinus checing f the firing prcess. In case f any malfunctin the display will shw an errr message pinting t the prblem. Fllwing is a descriptin f the pssible errr messages: The iln desn t fllw the required temperature increase. This errr message pints clearly t a iln prblem. Pssible cause: bren fuse, pwer phase r relay failed the dr (lid) cntact is pen a heating element is bren the heating elements are t ld (esp.with high firing temperatures) the thermcuple has a shrt circuit Thermcuple r thermcuple circuit defect Pssible cause: thermcuple bren thermcuple wiring bad cntacts f the cnnecting plug bad Impssible values n data acquisitin Pssible cause: thermcuple plarized bad thermcuple temperature less than -15 C Safety Switch Off features was activated The TC60 has measured an vertemperature in the iln and switched ff the iln by the 2nd pwer relay (if fitted). Chec carefully the cause befre using the iln again t avid further damage! As yur dealer fr assistance. 12
Errr detected during pwer-up self chec On every pwer-up the cntrller perfrms a self chec. If an errr is detected the cntrller shws F8 (ROM errr) r F9 (hardware errr). Please cntact yur lcal dealer. Setting the Parameters f the TC40 This infrmatin describes hw t adapt the TC40 t the iln. Usually, this is dne by the iln manufacturer. Yu can call up the parameters t view nly; t change them, yu need a special authrizatin cde which is available frm us n request. T get int the parameter menu press the ey start/stp and hld it pressed fr abut 4 secnds. Nw, the display reads the first cnfigurable value and yu can step thrugh the list by pressing the ey (3). cde usage value range unit 0 type f thermcuple S-R-K-J 0-3 - 1 max. adjustable temperature 20-1600 C 2 prprtinal band 0.0-99.9 % 3 integral time 10-8000 s 4 derivative time 0-999 s 5 cyclus time pwer relay 1-100 s 6 units fr temperatures C - F 0-1 - 7 lc errr message F1 (heat up chec) 0-1 - 8 temp. fr switching ver t full pwer 20-1600 C 13
