Kufotokozera Kwambiri
505E ndi chowongolera cha 32-bit microprocessor chopangidwa kuti chizitha kutulutsa kamodzi, kuchotsa / kulowetsa, kapena kulowetsa ma turbines a nthunzi. 505E ndi yokonzeka kumunda, kulola kuti mapangidwe amodzi agwiritsidwe ntchito pazinthu zosiyanasiyana zowongolera ndikuchepetsa mtengo ndi nthawi yotsogolera. Imagwiritsa ntchito mapulogalamu oyendetsedwa ndi menyu kuwongolera mainjiniya akumunda pakukonza owongolera ku jenereta kapena kugwiritsa ntchito makina oyendetsa. 505E ikhoza kukonzedwa kuti igwire ntchito ngati gawo loyima kapena itha kugwiritsidwa ntchito molumikizana ndi makina owongolera omwe amagawika.

505E ndi gawo losinthika la turbine la nthunzi ndi gulu lowongolera (OCP) mu phukusi limodzi. 505E ili ndi gulu lowongolera la opareshoni kutsogolo lomwe limaphatikizapo mizere iwiri (24-character pamzere) ndi seti ya makiyi 30. OCP iyi imagwiritsidwa ntchito kukonza 505E, kupanga masinthidwe a pulogalamu yapaintaneti, ndikugwiritsa ntchito turbine/system. Chiwonetsero chamizere iwiri cha OCP chimapereka malangizo osavuta kumva m'Chingerezi, ndipo wogwiritsa ntchito amatha kuwona zenizeni komanso zoyika pazithunzi zomwezo.

Ma 505E amalumikizana ndi ma valve awiri owongolera (HP ndi LP) kuti aziwongolera magawo awiri ndikuchepetsa gawo limodzi lowonjezera ngati pakufunika. Zigawo ziwiri zomwe zimayendetsedwa ndi liwiro (kapena katundu) ndi kuthamanga / kulowetsa (kapena kutuluka), komabe, 505E ingagwiritsidwe ntchito kulamulira kapena kuchepetsa: turbine inlet pressure kapena kutuluka, kutulutsa (kubwerera kumbuyo) kuthamanga kapena kuthamanga, kuthamanga kwa gawo loyamba, kutulutsa mphamvu ya jenereta, kulowetsa zomera ndi / kapena kutulutsa, kontrakitala kulowetsa kapena kutulutsa mphamvu yamtundu uliwonse, ndondomeko yamtundu uliwonse, ndondomeko ya turbine kapena kayendedwe ka turbine.

505E imatha kuyankhulana mwachindunji ndi makina owongolera omwe amagawika ndi / kapena gulu lowongolera opangira CRT kudzera pamadoko awiri a Modbus. Madokowa amathandizira kulumikizana kwa RS-232, RS-422, kapena RS-485 pogwiritsa ntchito njira zotumizira za ASCII kapena RTU MODBUS. Kulumikizana pakati pa 505E ndi chomera cha DCS kumathanso kuchitidwa kudzera pa intaneti yolimba. Chifukwa ma seti onse a 505E PID amatha kuwongoleredwa pogwiritsa ntchito ma siginecha a analogi, mawonekedwe a mawonekedwe ndi kuwongolera sikuperekedwa nsembe.

The 505E imaperekanso zinthu zotsatirazi: Chiwonetsero cha ulendo woyamba (zolowera 5 zonse), kupewa kuthamanga kwambiri (2 mawilo othamanga), kutsatizana koyambira (kuyambira kotentha ndi kozizira), kuthamanga kwapawiri/kunyamula katundu, kudziwika kwa zero liwiro, nsonga yothamanga kwambiri paulendo wothamanga kwambiri, ndi kugawana katundu wofanana pakati pa mayunitsi.
