Uqhagamshelo

I-RST 25 ingaqhagamshelwa ngolu hlobo lulandelayo kumzobo wofakelo:
I-FlG1: Uqhagamshelo lwe-relay ngaphambi kokusebenza.
Xa ireyila iqhagamshelwe njengakwiFIG 1, ii-L1, L2 kunye ne-L3 ze-LED ezintathu ezimthubi ziyakhanya xa umbane wesigaba se-A1 L, i-A2 Neutral, kunye nezigaba ezintathu”L1,”L2” kunye”L3” ziqhagamshelwe ngokufanelekileyo.
Ukuba akukho umbane ogqithisileyo okanye ukusilela kwesigaba solandelelwano lwesigaba, i-LED eluhlaza iyakhanya (ii-terminals 11 kunye ne-14 zivaliwe) kwaye i-relay ilungele ukusebenza.
UMZOBO 2: Uqhagamshelo lwe-relay emva komsebenzi.
Xa ireyila iqhagamshelwe njengakwiFIG 2, (umbane we-Al phase L, i-A2 Neutral iqhagamshelwe ngokufanelekileyo) emva kokusebenza, izigaba ezintathu "L1″,"L2″ kunye"L3″ ziqhagamshelwe, kwaye akukho ngaphantsi kwe-overvoltage, i-phase falure, i-phase sequence, i-LED eluhlaza iyakhanyisa (ii-terminals 11 kunye ne-terminals 11).
14 zivaliwe) kwaye ireyila ilungele ukuzigcina.
Kunokwenzeka kwakhona ukuqhagamshela umbane emva kokusebenza kwiFIG2.
NgokweMifanekiso 1 kunye no-2, isiphelo sendlela "PE" kufuneka sisekelwe.

Umbane ongaphantsi kwamandla
Umda we-undervoltage ofunekayo ungahlengahlengiswa ube yi--25% UN.

Umbane ogqithisileyo
Umda we-overvoltage oyifunayo ungalungiswa ukuya kuthi ga kwi-+25% UN.

Ukungalingani
Xa kulungiswa umda we-over-and undervoltage, umda we-asymmetric nawo uyalungiswa.

Ukulibaziseka kwexesha
Ixesha lokucima i-injini linokulungiswa yi-potentiometer ethi “Time' Delay” ukusuka kwimizuzwana eyi-0.1….5. Ngale function kunokwenzeka ukulungisa ixesha lokuchonga ukusilela.

Ulawulo lweContactor
Ukuba isigaba siyasilela ngexesha lokusebenza xa kulayishwa okanye enye yeziqhagamshelwano ze-contactor okanye i-circuit breaker inesiphene, (ukuqhawuka koqhagamshelwano okanye ukutsha konxibelelwano), i-RST 25 iyayibona intsilelo, kunye ne-feedback voltage, kwaye iyacima ngokuxhomekeke kulungiselelo lwe-"Time Delay".
I-RST 25 ilawula utshintsho lwesigaba. Ukuba kukho ukusilela kwesigaba ngexesha lokusebenza, i-engile evela kwi-voltage yempendulo yi-30° kwaye i-RST 25 iyakuqonda oku kusilela.
