Khadi yoteteza makina a MPC4 ndiye chinthu chapakati mu VM600 series machinery protection system (MPS). Khadi losunthika kwambirili limatha kuyeza ndi kuyang'anira ma siginoloji anayi osunthika komanso kulowetsa ma liwiro awiri nthawi imodzi.

Zolowetsera zamasiginecha zosinthika zimatha kukonzedwa bwino ndipo zimatha kuvomereza ma siginecha omwe akuyimira kuthamanga, kuthamanga ndi kusamuka (kuyandikira), pakati pa ena. Kukonzekera kwa ma multichannel pa board kumalola kuyeza kwa magawo osiyanasiyana akuthupi, kuphatikiza kugwedezeka kwachibale ndi mtheradi, Smax, eccentricity, thrust position, kukulitsidwa kwathunthu ndi kosiyana kwa nyumba, kusamuka komanso kukakamizidwa kwamphamvu.

Kukonzekera kwa digito kumaphatikizapo kusefa kwa digito, kusakanikirana kapena kusiyanitsa (ngati kuli kofunikira), kukonzanso (RMS, mtengo wamtengo wapatali, nsonga yeniyeni kapena peak-to-peak), kutsata dongosolo (matali ndi gawo) ndi kuyeza kwa kusiyana kwa cholinga cha sensor.

Zolowetsa zothamanga (tachometer) zimalandila ma siginecha kuchokera ku masensa osiyanasiyana othamanga, kuphatikiza makina otengera ma probes oyandikira, masensa a maginito a pulse pickup kapena ma sign a TTL. Magawo a tachometer amathandizidwanso.

Kusinthaku kumatha kuwonetsedwa mu metric kapena mayunitsi achifumu. Zochenjeza ndi Zowopsa zimatha kutha kukonzedwa bwino, monganso kuchedwa kwa nthawi ya alamu, hysteresis ndi latching. Magawo a Alert ndi Danger amathanso kusinthidwa ngati ntchito ya liwiro kapena chidziwitso chilichonse chakunja.

Kutulutsa kwa digito kumapezeka mkati (pa khadi lolowera / lotulutsa la IOC4T) pamlingo uliwonse wa alamu. Zizindikiro za alamu izi zimatha kuyendetsa ma relay anayi akumaloko pa IOC4T khadi ndi/kapena zitha kuyendetsedwa pogwiritsa ntchito basi ya VM600 rack's Raw kapena Open Collector (OC) kuti muyendetse ma relay pamakadi otumizirana osankha monga RLC16 kapena IRC4.

Zizindikiro zosinthika (zogwedezeka) ndi zizindikiro zothamanga zimapezeka kumbuyo kwa rack (patsogolo la IOC4T) ngati zizindikiro zotulutsa analogi. Mphamvu yamagetsi (0 mpaka 10 V) ndi ma siginecha apano (4 mpaka 20 mA) amaperekedwa. MPC4 imadziyesa yokha ndi chizolowezi chodziwunikira pamagetsi. Kuphatikiza apo, khadi lopangidwa ndi "OK system" limawunika mosalekeza kuchuluka kwa ma siginecha omwe amaperekedwa ndi unyolo woyezera (sensor ndi / kapena chowongolera chizindikiro) ndikuwonetsa vuto lililonse chifukwa cha chingwe chosweka, sensa yolakwika kapena chowongolera chizindikiro.

Chizindikiro cha LED pa gulu lakutsogolo la MPC4 chikuwonetsa ngati vuto la kukonza kapena hardware lachitika. Ma LED ena asanu ndi limodzi (amodzi pa njira yolowera) akuwonetsa ngati OK System yazindikira cholakwika komanso ngati alamu yachitika panjira.

Khadi la MPC4 likupezeka m'mitundu itatu: "standard" version, "separate circuits" ndi "safety" (SIL) version, zomwe zimagwira ntchito ngati makhadi pogwiritsa ntchito IOC4T yolowera / yotulutsa khadi. Makadi a MPC4 osiyanasiyana Khadi la MPC4 likupezeka m'mitundu yosiyanasiyana, kuphatikiza "standard", "separate circuits" ndi "safety" (SIL).

Kuphatikiza apo, matembenuzidwe ena amapezeka ndi zokutira zofananira zomwe zimagwiritsidwa ntchito pozungulira makadi kuti atetezere chilengedwe ku mankhwala, fumbi, chinyezi komanso kutentha kwambiri. Mitundu yonse ya 'standard' ndi "safety" (SIL) ya khadi ya MPC4 ndi yovomerezeka ku IEC 61508 ndi ISO 13849, kuti igwiritsidwe ntchito pachitetezo chachitetezo, monga SIL 1 molingana ndi IEC 61508 ndi PL c molingana ndi ISO 13849-1. Khadi la "standard" MPC4 ndiye mtundu woyambirira ndipo imathandizira mawonekedwe onse ndi njira zosinthira. "standard" MPC4 imapangidwira machitidwe achitetezo omwe amagwiritsa ntchito rack VM600 yokhala ndi makhadi ochepa, ndiye kuti, "standard" MPC4/IOC4T makhadi awiri ndi makhadi a RLC16. Ili ndi mawonekedwe a akapolo a VMEcompatible kotero ndi mapulogalamu osinthika kudzera pa VME pakakhala CPUx khadi yomwe imagwira ntchito ngati rack controller mu VM600 rack. Ndi pulogalamu yosinthika kudzera pa RS-232 (pagawo lakutsogolo la khadi).

Khadi la "chitetezo" (SIL) MPC4, lodziwika kuti MPC4SIL, linapangidwa kuti lilole njira zambiri zoyikapo. Makamaka, ma rack a VM600 omwe alinso ndi makhadi owunikira momwe zinthu ziliri monga XMx16 ndi makhadi otumizirana mauthenga monga IRC4. Kuti chitetezo chitsimikizire masanjidwe awa, kunali koyenera kuwonetsetsa kuti MPC4SIL yasiyanitsidwa ndi makhadi ena mu VM600 rack, kotero kuti palibe kuthekera kwa kasinthidwe kake kusinthidwa mosadziwa. Choncho, khadi la MPC4SIL silimaphatikizapo mawonekedwe a akapolo ogwirizana ndi VME, siligwirizana ndi njira za tachometer (liwiro) ndipo silimapereka mphamvu zonse zowonetsera zizindikiro za khadi la "standard" la MPC4 (onani Zowonjezera Zowonjezera - za "standard" ndi "mabwalo osiyana" makadi a MPC4 okha patsamba 9). Kupatukana kwa MPS ndi CMS The VM600 rack, makhadi oteteza makina, makhadi owunika momwe zinthu ziliri ndi mapulogalamu ogwirizana nawo adapangidwa kuti azitsatira dongosolo la chitetezo cha makina (MPS) ndi zofunikira zowunikira (CMS) za muyezo wa API 670, zomwe zimawonetsetsa kuti magwiridwe antchito a MPS sadalira ndipo sasokonezedwa ndi CMS mwanjira iliyonse. Chifukwa chake ngakhale makhadi oteteza makina ndi makhadi owunikira momwe zinthu ziliri amatha kugawana mosavuta ma sensa kuchokera kumaketani oyezera, ma MPC4/IOC4T makhadi sagawana mabasi aliwonse olumikizirana ndi XMx16/XIO16T ma makhadi oyang'anira makhadi mu VM600 rack, ndipo ma MPC4/IOC4T makhadi amakonzedwa ndikuyendetsedwa ndi pulogalamu ya VMxM XMx16/XIO16T makhadi awiriwa amakonzedwa ndikugwiritsidwa ntchito pogwiritsa ntchito pulogalamu ya VibroSight®). Zambiri za mapulogalamu Akagwiritsidwa ntchito ngati makhadi okhala ndi IOC4T yolowetsa/yotulutsa, MPC4 ndiyoyenera kwambiri kuyang'anira makina ndi kuteteza pamakina osiyanasiyana. Kuti mumve zambiri pakugwiritsa ntchito mawiri a MPC4/IOC4T makadi onse, onani buku la hardware la VM600 machinery protection system (MPS) ndi VM600 MPSx software manual. Kuti mudziwe zambiri pakugwiritsa ntchito mawiri a MPC4/IOC4T makhadi pachitetezo chogwira ntchito, onani buku la chitetezo cha VM600. Kuti mudziwe zambiri, funsani woimira Meggitt kwanuko.
