MPC4 machinery tiv thaiv daim npav yog lub hauv paus ntsiab lus hauv VM600 series machinery protection system (MPS). Daim npav muaj ntau yam no muaj peev xwm ntsuas thiab saib xyuas txog li plaub lub teeb liab dynamic inputs thiab mus txog rau ob qhov ceev inputs ib txhij.

Lub teeb liab dynamic inputs yog programmable tag nrho thiab tuaj yeem lees txais cov teeb liab sawv cev acceleration, tshaj tawm thiab hloov chaw (qhov sib thooj), thiab lwm yam. On-board multichannel ua tso cai rau kev ntsuas ntawm ntau yam ntawm lub cev tsis muaj zog, suav nrog cov txheeb ze thiab tsis muaj kev vibration, Smax, eccentricity, thrust txoj hauj lwm, qhov tseeb thiab qhov sib txawv ntawm cov vaj tsev nthuav dav, kev hloov pauv thiab lub zog siab.

Cov txheej txheem digital suav nrog kev lim dej digital, kev sib koom ua ke lossis kev sib txawv (yog tias xav tau), rectification (RMS, tus nqi txhais tau tias, qhov tseeb ncov lossis qhov tseeb ncov-rau-peak), kev txiav txim taug qab (amplitude thiab theem) thiab ntsuas qhov ntsuas qhov sib txawv.

Qhov ceev (tachometer) inputs txais cov teeb liab los ntawm ntau yam ceev sensors, nrog rau cov tshuab raws li kev sojntsuam ze, sib nqus pulse pickup sensors lossis TTL teeb liab. Fractional tachometer ratios kuj tau txais kev txhawb nqa.

Lub configuration yuav qhia nyob rau hauv metric los yog imperial units. Cov ntsiab lus ceeb toom thiab phom sij yog qhov programmable, raws li lub sijhawm tswb qeeb, hysteresis thiab latching. Cov qib ceeb toom thiab phom sij kuj tuaj yeem hloov kho raws li kev ua haujlwm ntawm kev ceev lossis cov ntaub ntawv sab nraud.

Cov zis digital muaj nyob rau sab hauv (ntawm IOC4T input/output card sib raug) rau txhua qib tswb. Cov cim ceeb toom no tuaj yeem tsav plaub lub hauv zos relays ntawm daim npav IOC4T thiab / lossis tuaj yeem siv tau siv VM600 rack's Raw bus lossis Open Collector (OC) tsheb npav los tsav cov relays ntawm cov ntawv xaiv relay xws li RLC16 lossis IRC4.

Cov txheej txheem dynamic (vibration) cov teeb liab thiab cov teeb liab ceev muaj nyob rau tom qab ntawm lub khib (ntawm lub vaj huam sib luag pem hauv ntej ntawm IOC4T) raws li cov cim tso tawm analog. Voltage-based (0 mus rau 10 V) thiab tam sim no-raws li (4 mus rau 20 mA) cov teeb liab raug muab. MPC4 ua qhov kev kuaj tus kheej thiab kev kuaj mob niaj hnub ntawm lub zog-up. Tsis tas li ntawd, daim npav builtin "OK system" txuas ntxiv saib xyuas cov theem ntawm cov teeb liab muab los ntawm cov ntsuas ntsuas (sensor thiab / lossis lub teeb liab txias) thiab qhia tias muaj teeb meem vim muaj kab sib kis, faulty sensor lossis teeb liab txias.

Qhov taw qhia LED ntawm MPC4 pem hauv ntej vaj huam sib luag qhia seb puas muaj kev ua haujlwm lossis kho vajtse yuam kev. Rau qhov ntxiv LEDs (ib qho ntawm ib qho channel input) qhia seb qhov OK System puas tau kuaj pom qhov ua txhaum thiab seb lub tswb puas tshwm sim ntawm lub channel.

Daim npav MPC4 muaj nyob rau hauv peb versions: "tus qauv" version, "sib cais circuits" version thiab "kev nyab xeeb" (SIL) version, tag nrho cov no ua haujlwm ua ib daim npav uas siv IOC4T input / output card. Cov ntawv sib txawv ntawm MPC4 daim npav MPC4 muaj nyob rau hauv ntau hom, suav nrog "tus qauv", "sib cais" thiab "kev nyab xeeb" (SIL) versions.

Tsis tas li ntawd, qee cov qauv muaj nyob rau hauv cov txheej txheem conformal siv rau lub voj voog ntawm daim npav rau kev tiv thaiv ib puag ncig ntxiv rau cov tshuaj, plua plav, noo noo thiab kub heev. Ob qhov 'tus qauv' version thiab "kev nyab xeeb" (SIL) versions ntawm MPC4 daim npav tau lees paub rau IEC 61508 thiab ISO 13849, siv rau hauv kev nyab xeeb kev nyab xeeb, xws li SIL 1 raws li IEC 61508 thiab PL c raws li ISO 13849-1. Daim npav "tus qauv" MPC4 yog tus thawj version thiab txhawb nqa txhua yam nta thiab ua hom. Tus "tus qauv" MPC4 yog npaj rau kev nyab xeeb siv VM600 khib nrog ntau yam ntawm daim npav, uas yog, "tus qauv" MPC4 / IOC4T daim npav khub thiab RLC16 relay phaib. Nws muaj VMEcompatible qhev interface yog li nws yog software configurable ntawm VME thaum muaj ib daim npav CPUx ua tus tswj khib hauv VM600 khib. Nws tseem yog software configurable ntawm RS-232 (nyob rau hauv pem hauv ntej vaj huam sib luag ntawm daim card).

Daim npav "kev nyab xeeb" (SIL) MPC4, hu ua MPC4SIL, tau tsim los tso cai rau ntau yam kev xaiv ntawm kev teeb tsa. Tshwj xeeb, VM600 racks uas tseem muaj cov ntawv saib xyuas mob xws li XMx16 thiab cov ntawv xa tawm xws li IRC4. Txhawm rau kom muaj kev nyab xeeb ua pov thawj cov kev teeb tsa no, nws yog qhov tsim nyog los xyuas kom meej tias MPC4SIL raug cais tawm ntawm lwm daim npav hauv VM600 khib, yog li tsis muaj qhov ua tau ntawm nws qhov kev teeb tsa raug hloov kho tsis raug. Yog li ntawd, daim npav MPC4SIL tsis suav nrog VME-compatible qhev interface, tsis txhawb lub tachometer (ceev) raws thiab tsis muab tag nrho cov teeb liab ua lub peev xwm ntawm "tus qauv" MPC4 daim npav (saib Ntxiv cov lus qhia ntxiv - rau "tus qauv" thiab "cov kab sib cais" MPC4 daim npav nkaus xwb nyob rau nplooj 9). Kev sib cais ntawm MPS thiab CMS Lub VM600 khib, cov ntawv tiv thaiv tshuab, daim npav saib xyuas mob thiab cov software cuam tshuam tau tsim los rau kev ua raws li cov txheej txheem tiv thaiv tshuab (MPS) thiab kev soj ntsuam xyuas qhov xwm txheej (CMS) kev sib cais ntawm API 670 tus qauv, uas ua kom ntseeg tau tias kev ua haujlwm ntawm MPS tsis nyob ntawm thiab tsis cuam tshuam los ntawm kev ua haujlwm ntawm CMS. Yog li txawm hais tias cov ntawv tiv thaiv tshuab thiab cov ntawv saib xyuas mob tau yooj yim qhia cov cim qhia los ntawm kev ntsuas cov saw hlau, MPC4 / IOC4T daim npav khub tsis qhia cov tsheb npav sib txuas lus nrog XMx16 / XIO16T mob saib xyuas daim npav khub hauv VM600 khib, thiab MPC4 / IOC4T daim npav khub tau teeb tsa thiab ua haujlwm siv daim npav VMx600 (MPSX600) Cov khub tau teeb tsa thiab ua haujlwm siv VibroSight® software). Cov ntaub ntawv siv thaum siv los ua ib daim npav nrog IOC4T input / output card, MPC4 yog qhov tsim nyog rau kev saib xyuas thiab kev tiv thaiv hauv ntau hom kev lag luam. Yog xav paub ntxiv txog kev siv MPC4/IOC4T daim npav ua ke feem ntau, xa mus rau VM600 machinery protection system (MPS) hardware manual and the VM600 MPSx software manuals. Yog xav paub txog kev siv MPC4 / IOC4T daim npav ua khub hauv cov ntsiab lus kev nyab xeeb, xa mus rau VM600 phau ntawv qhia kev nyab xeeb.
