5 Alication xamls Controlling a ositioning cylindr in th ar and rinting industry Th lctric signal coming from a controllr or a PLC () is convrtd to a numatic signal () by th / convrtr. Th rssur signal is usd to osition a cylindr which, in turn, movs a rollr that ks th ar undr a crtain tnsion. Air Ty 6111 Controlling a valv Valvs quid with small numatic actuators can b controlld dirctly by an / convrtr. Th / convrtr rcivs th lctric signal from a controllr or a PLC. Th / convrtr can also control a numatic ositionr. Fild or industrial units can b mountd dirctly to a valv (attachmnt to rod-ty yok or according to NAMUR). Air Ty 6116 Prssur control Th / convrtr masurs th rssur in th ilin and convrts it to an lctric signal. Th controllr uss th lctric signal to calculat th control signal which is assd on by th ositionr to finally clos or on th numatic control valv. Ty T 6000

6 Filling of liquids in th bvrag industry and brwris Th / convrtr convrts an lctric signal to a numatic signal. Th numatic signal controls cylindrs which insrt filling tubs mor or lss d, dnding on th liquid lvl, into bottls, filling thm with bvrags or dtrgnts. Air Ty 6126 To th PLC Boostr control Boostrs ar usd to amlify th flow rat of comrssd air. To control boostrs, you can us, aart from handwhls, also / convrtrs which rciv an lctric signal from a controllr or a PLC. Ty 6111 Air Alying adhsiv or glu Glu or adhsiv is to b alid on diffrnt bass. Dnding on th sd of th convyor blt, varying quantitis must b alid. Th / convrtr rcivs an lctric signal, which changs with th blt sd, and convrts it to a rssur signal. Th rssur causs th ball of a disnsr to adat th outlt to th rquird amount of glu or adhsiv. This nsurs uniform alication. Ty 6126 Air 6 T 6000

7 Exlosion rotction Som of th SAMSON / Convrtrs ar suitabl for us in hazardous aras as thy ar frquntly found in th chmical and trochmical industry. Imortant factors of th xlosion rotction rlvant for such alications ar listd in th following. For dtails, las rfr to th standards indicatd. Zon classification Hazardous aras ar groud into zons to indicat th dangr of xlosion. Each zon rscribs articular masurs which nsur xlosion rotction.

8 Safty barrirs according to DIN and EN Sction 8 Safty barrirs ar assiv ntworks which sarat intrinsically saf and not intrinsically saf circuits without isolating thm lctrically. Th outut circuits of th safty barrirs mt th rquirmnts of th intrinsic safty ia and ib. Safty barrirs ar always installd outsid th hazardous ara. Circuit diagram of a safty barrir IP Dgr of rotction Th IP cod charactrizs an lctrical alianc s rotction against accidntal contact and forign articls as wll as its rotction against watr.

9 Tmratur control Th SAMSON controllrs TROVIS 6412, 6493 and 6497 allow th ralization of siml tmratur control systms,.g. flow tmratur control in hating installations. Th flow tmratur is masurd with a Pt 100 snsor and transmittd to th controllr. Th lattr controls a numatic control valv by issuing an analog 4 to 20 ma signal via an i/ ositionr. TROVIS 6493 TROVIS 6497 TROVIS 6412 Mixing of two liquids TROVIS 6412 can b usd for ratio control whn two liquids ar mixd. Th controllr obtains signals from two diffrntial rssur transmittrs and root-xtracts th signals. Th controllr thn uss th signals to calculat an outut signal for th control valv which must rach th rquird mixing ratio. Flow control TROVIS 6412 and 6493 rovid a convnint flow control. Whn using th root-xtracting function of ths controllrs, th flow rat can b asily calculatd from th diffrntial rssur signal issud by th diffrntial rssur transmittr. Th analog outut signal of th controllr activats th ositionr and with it th numatic valv. 9 T 6000

10 Tmratur control with function gnration Th SAMSON controllrs TROVIS 6412 and 6493 also allow th ralization of a tmratur control with function gnration,.g. an outdoor tmratur-controlld flow tmratur control. Th outdoor tmratur is masurd with an Pt 100 snsor and assd on to th controllr which utilizs function gnration to dirctly convrt th outdoor tmratur to a st oint for th flow tmratur. Th controllr activats th lctric control valv using a thr-st signal. Tmratur cascad control Th boilr is hatd by a hat xchangr. To minimiz th dlays of th controlld systm, cascad control with a mastr and a slav controllr is imlmntd. TROVIS 6412 is articularly suitd to solv this task sinc it is caabl of bing th mastr and th slav controllr at th sam tim. It is also ossibl to us two TROVIS 6497 or two TROVIS 6493 controllrs. Th mastr controllr masurs th actual boilr tmratur and forwards its maniulatd variabl as rfrnc variabl WE to th slav controllr. Th slav controllr controls th flow tmratur in th hat xchangr loo. Th control valv is activatd using a thr-st signal. M x WE y x TROVIS TROVIS TROVIS 6493 Limiting control TROVIS 6412 is also a good choic whn rforming limiting control with minimum slction, as shown in th xaml oosit. Th color is to b hatd to a crtain rdtrmind tmratur, howvr, th shll tmratur of th raction tank must not xcd th tmratur of th color by a rdtrmind valu. Th raction tank is hatd or coold down using two hat xchangrs. Th main controllr controls th tmratur of th color. Th limiting controllr controls th tmratur diffrnc btwn th tank shll tmratur and th color tmratur. Th color tmratur is alid to th analog outut AA, fd back to th controllr inut as disturbanc variabl and subtractd from th shll tmratur. Th minimum slction function fds th smallr control signal of both control loos to th slit-rang unit, thus activating both control valvs. x y WE TROVIS 6412 y AA SAMSON CONTROLS INC Rivira Driv Markham Ontario Canada L3R 5J7 Tl.
