I-3500/25 Enhanced Keyphasor Module iwuhhafu wobude, imojuli yamashaneli amabili esetshenziselwa ukunikeza amasignali e-Keyphasor kumamojula okuqapha ku-3500 rack. Imojula ithola amasiginali okufakwayo kusuka kuma-proximity probe noma ama-pickup kazibuthe futhi iguqule amasiginali abe amasiginali ye-Keyphasor yedijithali abonisa lapho uphawu lwe-Keyphasor ku-shaft luqondana ne-Keyphasor transducer. I-3500 Machinery Protection System ingamukela amasiginali we-Keyphasor amane ukuze acushwe okuvamile kanye namasiginali we-Keyphasor afika kwayisishiyagalombili ekucushweni okubhanqiwe.

Isiginali ye-Keyphasor iyi-pulse eyodwa-per-turn noma i-multiple-event-per-turn pulse kusuka ku-shaft ejikelezayo noma igiya elisetshenziselwa ukunikeza isilinganiso esinembile sesikhathi. Lokhu kuvumela amamojula okuqapha angama-3500 kanye nemishini yokuxilonga yangaphandle ukukala isivinini sokujikeleza kwe-shaft kanye nemingcele ye-vector efana ne-1X vibration amplitude nesigaba.
I-Ehanced Keyphasor Module iyimojuli yesistimu ye-3500 ethuthukisiwe. Inikeza amandla anwetshiwe okucubungula isignali ye-Keyphasor ngaphezu komklamo wangaphambili kuyilapho igcina ukuhambisana okuphelele okuya phansi ngokwefomu, ukulingana nokusebenza namamojula akhona we-Keyphasor ukuze asetshenziswe ezinhlelweni zefa. Imodyuli ye-Keyphasor, i-PWA 125792-01, ithathelwa indawo ngokuphelele imojuli ebuyekeziwe ye-149369-01.

Uma isistimu yokufaka i-Keyphasor idingeka ezinhlelweni zokusebenza ze-Triple Modular Redundant (TMR), isistimu ye-3500 kufanele isebenzise amamojula amabili we-Keyphasor. Kulokhu kulungiselelwa, amamojula asebenza ngokufana ukuze anikeze kokubili isignali ye-Keyphasor eyinhloko neyesibili kwamanye amamojula ku-rack. Isistimu enokufakwa kwe-Keyphasor okungaphezu kokune ingase isebenzise ukucushwa okubhanqiwe inqobo nje uma kungekho amasiginali wokufaka we-Keyphasor ayisisekelo angaphezu kwamane. Ukucushwa okubhanqiwe kudinga izikhundla zokuqapha ezimbili ezilandelanayo endaweni engaphezulu/ephansi noma zombili zesikhala sohhafu. Amamojula amane e-Keyphasor azokwamukela amashaneli amane okufaka ayisipele namane futhi ahlinzeke ngamashaneli amane okukhiphayo (okukodwa ngemojuli ngayinye). Ukucushwa kwamamojula amabili abhanqiwe neyodwa engabhanqiwe (inani lamamojula amathathu we-Keyphasor) nakho kungenzeka. Ekucushweni okunjalo, umsebenzisi angase alungiselele i-Keyphasor eyodwa engabhanqiwe (i-oda iziteshi ezimbili ezi-2 noma eyodwa-isiteshi esingu-1 kanye nenketho eyodwa yamashaneli angu-2)

I-Isolated Keyphasor I/O module yakhelwe izinhlelo zokusebenza lapho amasiginali we-Keyphasor eboshelwe ngokufana kumadivayisi amaningi futhi adinga ukuhlukaniswa kwamanye amasistimu, njengesistimu yokulawula. Imojuli ye-I/O Eyodwa yadalelwa ngokukhethekile izinhlelo zokusebenza ze-Magnetic Pickup kodwa iyahambisana futhi izohlinzeka ngokuhlukaniswa kwezinhlelo zokusebenza ze-Proximitor* inqobo nje uma ukunikezwa kwamandla kwangaphandle kunikezwa.

Inhloso yale mojula ye-I/O ngokuyinhloko bekuwukukala isivinini se-shaft hhayi isigaba. Imojula inganikeza izilinganiso zesigaba, kodwa le I/O yethula ukushintsha kwesigaba okuphezulu kancane kunenguqulo ye-Non-Isolated I/O. Umfanekiso 1 ubonisa inani lokushintsha kwesigaba amamojula e-Isolated I/O azokwengeza ngesivinini esihlukile somshini.

Izici zomkhiqizo ezithuthukisiwe zifaka phakathi ukukhiqizwa kwamasiginali wesehlakalo esisodwa ngesikhathi esisodwa kusukela kokokufaka kwemicimbi eminingi, i-firmware ethuthukisiwe yasenkambu, kanye nokubikwa kwedatha yokuphathwa kwempahla.
