EN is no fulfilled (This leads o a designaed error message of he conroller) Compliance wih hese sandards and provisions is only guaraneed if original accessories and/or peripheral componens approved by ROPEX are used. If no, hen he equipmen is operaed on he user's own responsibiliy. The CE marking on he conroller confirms ha he device iself complies wih he above-menioned sandards. I does no imply, however, ha he overall sysem also fulfils hese sandards. I is he responsibiliy of he machine manufacurer and of he user o verify he compleely insalled, wired and operaionally ready sysem in he machine wih regard o is conformiy wih he safey provisions and he EMC direcive (see also secion 8.3, "Power supply"). If peripheral componens (e.g. he ransformer or he line filer) from oher manufacurers are used, no funcional guaranee can be provided by ROPEX. 1.6 Warrany provisions The sauory provisions for warranies apply for a period of 12 monhs following he delivery dae. All devices are esed and calibraed in he facory. Devices ha have been damaged due o fauly connecions, dropping, elecrical overloading, naural wear, incorrec or negligen handling, chemical influences or mechanical overloading as well as devices ha have been modified, relabeled or oherwise alered by he cusomer, for example in an aemp o repair hem or insall addiional componens, are excluded from he warrany. Warrany claims mus be examined in he facory and approved by ROPEX. 2 Applicaion This RESISTRON emperaure conroller is an inegral par of he "series 4", he ousanding feaure of which is is microprocessor echnology. All RESISTRON emperaure conrollers are used o conrol he emperaure of heaing elemens (heasealing bands, beaded bands, cuing wires, heasealing blades, solder elemens ec.), as required in a variey of heasealing processes. The conroller is mos commonly used for impulseheasealing PE and PP films in simple able welding machines and welding presses: Pouch, filling and sealing machines Film wrapping machines Pouch-making machines L-sealers ec. The use of RESISTRON emperaure conrollers resuls in: Repeaable qualiy of he heaseals under any condiions Increased machine capaciy Exended life of he heasealing bands and eflon coaings Simple operaion and conrol of he sealing process Page 4

5 Principle of operaion 3 Principle of operaion The resisance of he heasealing band, which is emperaure-sensiive, is moniored 5x per second (6x a 6Hz) by measuring he curren and volage. The emperaure calculaed wih he help of hese measuremens is displayed and compared wih he se poin. The secondary volage of he impulse ransformer is adjused by phase-angle conrol if he measured values deviae from he se poin. The resuling change in he curren hrough he heasealing band leads o a change in he band emperaure and hus also is resisance. This change is measured and evaluaed by he RESISTRON emperaure conroller. The conrol loop is closed: ACTUAL emperaure = SET emperaure. Even minue hermal loads on he heasealing band are deeced and can be correced quickly and precisely. The hermoelecric conrol loop which is formed has a highly dynamic response because purely elecrical variables are measured a a high sampling rae. PLEASE NOTE! RESISTRON emperaure conrollers play a significan role in enhancing he performance of modern machines. However, he full benefi can only be obained from he advanced echnology offered by his conrol sysem if all he sysem componens, in oher words he heasealing band, he impulse ransformer, he wiring, he iming signals and he conroller iself, are compaible wih one anoher. We will be pleased o conribue our many years of experience owards opimizing your heasealing sysem. 4 Descripion of he conroller The microprocessor echnology endows he RESISTRON emperaure conroller wih previously unaainable capabiliies: Very simple operaion hanks o AUTOCAL, he auomaic zero calibraion funcion. Good dynamic response of he conrol sysem hanks o AUTOTUNE, which adaps auomaically o he conrolled sysem. High precision hanks o furher improved conrol accuracy and linearizaion of he heasealing band characerisic. High flexibiliy: Secondary volage range from 12V o 42V, curren range from 2A o 9A. Auomaic adjusmen o he line frequency in he range from 47Hz o 63Hz. Increased proecion agains dangerous condiions, such as overheaing of he heasealing band. A ime conrol (imer) funcion inegraed in he conroller enables he complee heasealing process o be conrolled on simple machines, such as able heasealing ools. A configurable relay oupu can be used o drive moors, energize magnes ec. The process daa is represened on an LC display wih 4 lines and 2 characers. Various display languages can be seleced. The real heasealing band emperaure is visualized on he display boh as a digial number in C and in he form of a dynamic bar. In addiion o he digial and bar indicaions on he display, he ACTUAL emperaure of he heasealing band is supplied o an analog 1VDC oupu. The real heasealing band emperaure can hus be visualized on an exernal emperaure meer (e.g. ATR-x). The RESISTRON emperaure conroller also feaures an inegraed faul diagnosis funcion, which ess boh he exernal sysem (heasealing band, wiring ec.) and he inernal elecronics and oupus a selecive error message in case of a faul.

The geomery of he heasealing band is oo complex o be discussed a lengh here. We shall herefore only refer o a few of he mos imporan physical and elecrical properies: The measuring principle applied for his sysem necessiaes a heasealing band alloy wih a suiable emperaure coefficien TCR, i.e. one whose resisance increases as he emperaure rises. Too low a TCR leads o oscillaion or unconrolled heaing. When heasealing bands wih a higher TCR are used, he conroller mus be calibraed for his. The firs ime he heasealing band is heaed o approximaely 2 25 C, he sandard alloy undergoes a once-only resisance change (burn-in effec). The cold resisance of he heasealing band is reduced by approximaely 2 3%. However, his a firs glance sligh resisance change resuls in a zero poin error of 2 3 C. The zero poin mus herefore be correced afer a few heaing cycles ( secion "Burning in he heasealing band" on page 26). One very imporan design feaure is he copper or silver-plaing of he heasealing band ends. Cold ends allow he emperaure o be conrolled accuraely and increase he life of he eflon coaing and he heasealing band. An overheaed or burned-ou heasealing! band mus no longer be used because he TCR has been alered irreversibly Burning in he heasealing band If a new heasealing band has been used, he zero poin is firs of all calibraed while he band is sill cold by acivaing he "AUTOCAL" funcion on he conroller. When he "AUTOCAL" funcion has finished, he display shows he preseleced calibraion emperaure (defaul value: 2 C). Adjus he se poin o approximaely 25 C and press he "HAND" key (assuming sep 213 has no been locked in he Configuraion menu and he display is in he home posiion) o acivae he "START" signal and hea for approximaely 1 second. Afer recooling, he conroller usually indicaes a value less han 2 C. Repea he "AUTOCAL" funcion. The heasealing band has now been burned in and he change in he alloying properies sabilized. The burn-in effec described here does no occur if he heasealing band has already been hermally prereaed by he manufacurer. Page 26

The heasealing band mus be replaced in! accordance wih he insrucions provided by he manufacurer. Each ime he heasealing band is replaced, he zero poin mus be calibraed wih he AUTOCAL funcion while he band is sill cold, in order o compensae producion-relaed resisance olerances.

If a emperaure range of 2 C is se for he conroller wih sep 25 in he Configuraion menu, i appears a his oupu in he 3 C range. A 4 C emperaure range is indicaed as 5 C. An indicaing insrumen can be conneced o his oupu in order o visualize he emperaure of he heasealing band. If an alarm is signaled, his analog oupu is used in addiion o he value indicaed on he conroller o display a selecive error message ( secion 1.21 "Error messages" on page 45). This oupu is no poenial-free and could! have he poenial of he secondary volage of he impulse ransformer. Exernal grounding is no allowed. If his warning is ignored, he conroller will be damaged by frame currens. Conac volage proecion mus be insalled a he erminals of he exernal emperaure meer. 1.8 Auomaic zero calibraion (AUTOCAL) Owing o he auomaic zero calibraion (AUTOCAL) funcion, here is no need o adjus he zero poin manually on he conroller. The "AUTOCAL" funcion maches he conroller o he curren and volage signals ha are presen in he sysem. You can acivae his funcion by selecing sep 17 in he Seings menu and hen pressing he "ENTER" key. The iniial emperaure (ambien emperaure) of he heasealing bar(s) which is currenly valid for calibraion can be se beforehand in he 4 C range using he "UP" and "DOWN" keys. The zero poin is calibraed in he facory o 2 C. The auomaic calibraion process akes around 1 15 seconds. The heasealing band is no heaed unil he calibraion process has finished. The message "- Calibraion - Please wai..." appears on he display while he "AUTOCAL" funcion is execuing and a couner couns down from 14 o. The acual value oupu (erminals 1+11) is se o C (corresponds o VDC) for he duraion of he calibraion process. You should always wai for he heasealing! band and he bar o cool down (o ambien emperaure) before acivaing he "AUTOCAL" funcion. Reasons for locked AUTOCAL funcion: 1. The "AUTOCAL" funcion canno be acivaed if he heasealing band cools down a a rae of more han.1k/second. This is addiionally indicaed wih sep 17 in he Seings menu by he message "Heasealing band sill ho! Please wai...". 2. If he "START" signal (HEAT) is acivaed, he "AUTOCAL" funcion is no execued. This is addiionally indicaed wih sep 17 in he Seings menu by he message "Auocal locked! (START sig. acive)". 3. The AUTOCAL funcion canno be acivaed if a faul wih error code 11 13, 21 23, 8xx or 9xx occurs ( secion 1.21 "Error messages" on page 45). Page 37

38 Conroller funcions 1.9 "FOOT SWITCH" signal The "FOOT SWITCH" signal is acivaed by means of a conrol conac a erminals FOOT SWITCH wih conac max. 5mA V Acivaing he "FOOT SWITCH" signal energizes relay K1 (or he opional solenoid drive). Among oher hings, his allows he closing movemen of he sealing jaws o be sared. Deacivaing he signal deenergizes relay K1 (or he solenoid drive) again immediaely, providing relay K1 is no energized by he ime conrol ( secion "Relay K1 / solenoid drive (opional)" on page 22). An addiionally parameerizable hold ime for he "FOOT SWITCH" signal is described in secion 1.1 "Hold ime for "FOOT SWITCH" signal" on page 38. The "FOOT SWITCH" signal is disabled as! long as he AUTOCAL funcion is execuing in he Seings menu (wih sep 17) or an alarm is displayed. I is no possible o acivae he "FOOT! SWITCH" signal again (in oher words, relay K1 or he solenoid drive canno be energized) for 2ms afer i is deacivaed in order o preven bouncing or oscillaion of he driven closing movemen. 1.1 Hold ime for "FOOT SWITCH" signal A hold ime beween and 2.s can be parameerized for he "FOOT SWITCH" signal wih sep 249 in he Configuraion menu. The relay (or he solenoid drive) remains closed for he parameerized ime afer his signal is acivaed, even if he signal is deacivaed again. Among oher hings, his permis he closing movemen of he sealing jaws o be sared by briefly acivaing and deacivaing he "FOOT SWITCH" signal. The hold ime is deacivaed if he value enered is "" (facory seing). The ime conrol mus energize relay K1! wihin he parameerized hold ime (acivaion of he "START" signal). If no, he conroller indicaes an alarm (error code 835) "START" signal (HEAT) Acivaing he "START" signal sars he inernally parameerized imeou. The ime a which he heasealing band begins o hea up depends on he seing of his parameer. The "START" signal mus be deacivaed again before he nex imeou is acivaed. Pressing he "HAND" key (assuming sep 213 has no been locked in he Configuraion menu and he display is in he home posiion) while he display is in he home posiion causes he heasealing band o sar heaing up immediaely. The inernal imeou is no sared. The "START" signal is acivaed by means of a conrol conac a erminals START (HEAT) wih conac max. 5mA V The "START" signal is disabled as long as he! "AUTOCAL" funcion is execuing in he Seings menu (wih sep 17). The se poin ha is seleced for he heasealing emperaure (sep 11 in he Seings menu) mus be greaer han 4 C. If no, he heasealing band will no be heaed up. As of sofware revision 8, i is no possible! o acivae he "START" signal again (in oher words, relay K1 or he solenoid drive canno be energized) for 2ms afer i is deacivaed in order o preven bouncing or oscillaion of he driven closing movemen.

The couner reading can be displayed wih sep 214 in he Configuraion menu. The cycle couner is rese o if he "ENTER" key is pressed or if he maximum coun of cycles is exceeded Single/double sealing Sep 24 deermines how he wo heasealing bands are heaed, depending on he design of he machine or equipmen. If wo heasealing bands for op and boom heaing are insalled in he machine, one of hese bands can be deacivaed for specific applicaions. The required seings can be configured wih sep 24: 1. "Double" (Facory seing) The wo heasealing bands are heaed simulaneously. The emperaure of boh bands is conrolled ogeher. 2. "Single" If wo heasealing bands are conneced o he conroller, only he firs is heaed. The second band is no used. Only he emperaure of he firs heasealing band is conrolled. If only one heasealing band is conneced o! he conroller, you mus se "Double" wih sep 24. The conroller will oherwise be overloaded and damaged beyond repair. If you change he configuraion wih! sep 24, you mus run he AUTOCAL funcion wih sep 17. If no, he conroller will no longer funcion correcly Hold mode The behavior of he digial indicaion of he ACTUAL emperaure in he home posiion can be changed wih sep 26 in he Seings menu. The following seings are possible: 1. "OFF" (Facory seing) If he main menu is visible on he display, he real ACTUAL emperaure is always indicaed. 2. "ON" If he display is in he home posiion, he ACTUAL emperaure ha was valid a he end of he las heasealing phase is always indicaed as a digial value. When he conroller is swiched on - or afer an alarm is acknowledged - he real ACTUAL emperaure is indicaed unil he end of he firs heaing phase. 3. "2 s" This seing causes he curren ACTUAL emperaure o be displayed as a digial value for an addiional 2 seconds a he end of a heasealing phase. This emperaure is hen indicaed again in real ime unil he end of he nex heaing phase. Hold mode only affecs he digial value on! he display. The ACTUAL emperaure in real ime is always indicaed, regardless of he seing, by he dynamic bar and he acual value oupu. Page 39
