ʻO ke kāleka pale mīkini MPC4 ka mea koʻikoʻi i ka VM600 series machinery protection system (MPS). Hiki i kēia kāleka maʻalahi ke ana a me ka nānā ʻana a hiki i ʻehā hoʻokomo hōʻailona hoʻoikaika a hiki i ʻelua hoʻokomo wikiwiki i ka manawa like.

Hiki ke hoʻolālā piha ʻia nā mea hoʻokomo hōʻailona ikaika a hiki ke ʻae i nā hōʻailona e hōʻike ana i ka wikiwiki, ka wikiwiki a me ka neʻe ʻana (kokoke), a me nā mea ʻē aʻe. Hiki i ka hana multichannel ma luna ke ana i nā ʻāpana kino like ʻole, me ka haʻalulu pili a me ka haʻalulu piha, Smax, eccentricity, kūlana thrust, hoʻonui hale kūʻokoʻa a me ka ʻokoʻa, neʻe a me ka ikaika ikaika.

ʻO ka hana kikohoʻe e pili ana i ka kānana kikohoʻe, hoʻohui a ʻokoʻa paha (inā makemake ʻia), hoʻoponopono (RMS, mean value, peak ʻoiaʻiʻo a peak-to-peak ʻoiaʻiʻo), ka nānā ʻana i ke kauoha (amplitude a me ka pae) a me ke ana ʻana o ka ʻāpana ʻike.

ʻO nā mea hoʻokomo wikiwiki (tachometer) e ʻae i nā hōʻailona mai nā ʻano mea ʻike wikiwiki, me nā ʻōnaehana e pili ana i ka proximity probes, magnetic pulse pickup sensor a i ʻole nā ​​hōʻailona TTL. Kākoʻo pū ʻia ka ratio fractional tachometer.

Hiki ke hōʻike ʻia ka hoʻonohonoho ʻana ma nā ʻāpana metric a imperial paha. Hiki ke hoʻonohonoho piha ʻia nā wahi hoʻonohonoho Alert a me Danger, e like me ka lohi o ka manawa alarm, hysteresis a me ka latching. Hiki ke hoʻololi ʻia nā pae Alert a Danger ma ke ʻano he hana o ka wikiwiki a i ʻole kekahi ʻike waho.

Loaʻa ka puka kikohoʻe ma loko (ma ke kāleka hoʻokomo/puka puka IOC4T) no kēlā me kēia pae hoʻāla. Hiki i kēia mau hōʻailona hōʻailona ke hoʻokele i ʻehā relay kūloko ma ke kāleka IOC4T a/a i ʻole hiki ke hoʻohana ʻia me ke kaʻa Raw bus o ka VM600 rack a i ʻole kaʻa Open Collector (OC) e hoʻokele i nā relay ma nā kāleka relay koho e like me ka RLC16 a i ʻole IRC4.

Loaʻa nā hōʻailona ikaika (vibration) a me nā hōʻailona wikiwiki ma ka hope o ka pahu (ma ka papa mua o ka IOC4T) ma ke ʻano he hōʻailona hoʻopuka analog. Hāʻawi ʻia nā hōʻailona ma muli o ka voltage (0 a 10 V) a me nā hōʻailona o kēia manawa (4 a 20 mA). Hana ka MPC4 i ka ho'āʻo ponoʻī a me ka maʻamau diagnostic ma ka mana-up. Eia kekahi, ʻo ke kāleka i kūkulu ʻia ʻo "OK system" ke nānā mau nei i ke kiʻekiʻe o nā hōʻailona i hāʻawi ʻia e kahi kaulahao ana (sensor a / a i ʻole ka mea hōʻailona hōʻailona) a hōʻike i kekahi pilikia ma muli o kahi laina haʻihaʻi haʻihaʻi, ʻike hewa ʻole a i ʻole nā ​​​​mea hōʻailona hōʻailona.

Hōʻike ʻia kahi hōʻailona LED ma ka papa mua MPC4 inā paha ua loaʻa kahi hana a i ʻole nā ​​​​hana hewa. ʻEono mau LED hou (hoʻokahi no kēlā me kēia ala komo) e hōʻike ana inā ua ʻike ka OK System i kahi hewa a inā paha ua loaʻa kahi alaala ma ke kahawai.

Loaʻa ka kāleka MPC4 i ʻekolu mau mana: kahi mana "maʻamau", kahi ʻano "kaapuni kaʻawale" a me kahi mana "palekana" (SIL), e hana ana ia mau mea āpau ma ke ʻano he kāleka me ka hoʻohana ʻana i kahi kāleka hoʻokomo/puka puka IOC4T. Nāʻano likeʻole o ke kāleka MPC4 Loaʻa ka kāleka MPC4 i nāʻano likeʻole, me nāʻano "maʻamau", "nā kaʻa kaʻawale" a me ka "palekana" (SIL).

Eia kekahi, loaʻa kekahi mau mana me kahi uhi conformal i hoʻopili ʻia i ka circuitry o ke kāleka no ka pale ʻana i ke kaiapuni hou i nā kemika, ka lepo, ka makū a me nā wela wela. ʻO ka mana 'maʻamau' a me nā mana "palekana" (SIL) o ke kāleka MPC4 i hōʻoia ʻia i IEC 61508 a me ISO 13849, no ka hoʻohana ʻana i nā pōʻaiapili palekana hana, e like me SIL 1 e like me IEC 61508 a me PL c e like me ISO 13849-1. ʻO ke kāleka MPC4 "maʻamau" ka mana kumu a kākoʻo i nā hiʻohiʻona āpau a me nā ʻano hana. Hoʻolālā ʻia ka MPC4 "maʻamau" no nā ʻōnaehana palekana me ka hoʻohana ʻana i kahi pahu VM600 me ka palena palena o nā kāleka, ʻo ia hoʻi, "maʻamau" MPC4 / IOC4T mau kāleka a me nā kāleka relay RLC16. Loaʻa iā ia kahi kikowaena kauā VME kūpono no laila hiki ke hoʻonohonoho ʻia ka polokalamu ma o VME ke loaʻa kahi kāleka CPUx e hana nei ma ke ʻano he mea hoʻokele rack ma ka VM600 rack. Hiki ke hoʻonohonoho pono ʻia ma o RS-232 (ma ka ʻaoʻao mua o ke kāleka).

Ua hoʻomohala ʻia ke kāleka MPC4 "palekana" (SIL), i kapa ʻia ʻo MPC4SIL, e ʻae i kahi ākea o nā koho hoʻonohonoho. ʻO ka kikoʻī, nā pahu VM600 i loaʻa nā kāleka nānā kūlana e like me ka XMx16 a me nā kāleka relay e like me ka IRC4. No ka palekana e hōʻoia i kēia mau hoʻonohonoho, pono ia e hōʻoia i ka hoʻokaʻawale ʻana o ka MPC4SIL mai nā kāleka ʻē aʻe i loko o kahi pahu VM600, no laila ʻaʻole hiki ke hoʻololi ʻia kona hoʻonohonoho ʻana. No laila, ʻaʻole i hoʻokomo ʻia ke kāleka MPC4SIL i kahi kikowaena kauā VME-compatible, ʻaʻole kākoʻo i nā kahawai tachometer (wikiwiki) a ʻaʻole hāʻawi i nā mana hana hōʻailona āpau o ke kāleka MPC4 "maʻamau" (e nānā i nā kikoʻī hou - no nā kāleka MPC4 "maʻamau" a me nā "kaapuni kaʻawale" wale nō ma ka ʻaoʻao 9). Hoʻokaʻawale ʻana o MPS a me CMS Ua hoʻolālā ʻia ka pahu VM600, nā kāleka pale mīkini, nā kāleka kiaʻi kūlana a me nā polokalamu e pili ana i ka hoʻokō ʻana i ka ʻōnaehana pale mīkini (MPS) a me ka ʻōnaehana nānā kūlana (CMS) nā koi hoʻokaʻawale o ka maʻamau API 670, e hōʻoiaʻiʻo ana ʻaʻole hilinaʻi ka hana o ka MPS a ʻaʻole i hoʻopaʻapaʻa ʻia e ka CMS. No laila, ʻoiai hiki i nā kāleka pale mīkini a me nā kāleka kiaʻi kūlana ke kaʻana like i nā hōʻailona sensor mai nā kaulahao ana, ʻaʻole e kaʻana like nā pālua kāleka MPC4/ IOC4T i nā kaʻa kamaʻilio me XMx16/XIO16T mau pai kāleka kiaʻi kūlana i loko o kahi pahu VM600, a ua hoʻonohonoho ʻia a hoʻohana ʻia nā pālua kāleka MPC4/IOC4T me ka hoʻohana ʻana i ka polokalamu VM600 MPSIOx6x1. hoʻonohonoho ʻia a hoʻohana ʻia me ka polokalamu VibroSight®). ʻIke noiʻi Ke hoʻohana ʻia ma ke ʻano he kāleka kāleka me kahi kāleka hoʻokomo/puka puka IOC4T, kūpono loa ka MPC4 no ka nānā ʻana a me ka pale ʻana i nā mīkini ma kahi ākea o nā noi ʻoihana. No ka ʻike hou aku e pili ana i ka hoʻohana ʻana i nā pālua kāleka MPC4/IOC4T ma ka laulā, e nānā i ka VM600 machinery protection system (MPS) manual hardware and the VM600 MPSx software manuals.
