Ukuhlolisisa
Isithiyo sokuphepha esihlukanisiweko esinemiphumela yokudlulisa iswitshi, esihlukanisa begodu sidlulisele amatshwayo wokufaka avela ebantwini beswitjhi nofana amaswitjhi aseduze eendaweni eziyingozi ukuya endaweni yokuphepha ene-relay yokukhipha ngokusebenzisa isithiyo sokuphepha. Ukutholwa kwephutha lelayini kwenziwa nge-LED phezulu kwemojuli. Iswitjhi yokudayela yemodyuli isetjenziselwa ukusetha ukufaka nokukhipha ngaphakathi kwesigaba nofana ukulawula okubuyela emuva, kanye nokuvumela nofana ukuvala umsebenzi wokutjengisa i-alamu yokuthola amaphutha welayini.
Umkhiqizo lo udinga ukuphakelwa kwamandla okuzijameleko, okuphakelwa kwamandla okuhlukileko, ukungena, nokukhipha amatheminali.

Qaphela: 1. I-PHD-12TF-277 ayifaki ingcenye yokufaka 2
2. Ukuphakelwa kwamandla wesitimela samandla kungumsebenzi ongakhetha kiwo.
Abasebenzisi kufuze batjho indlela yokuphakelwa kwamandla lokha naba-oda.
Sibawa uqale ukunamathiselwa ekhasini 89.
Ukutholwa kwephutha lelayini(LFD)
Abasebenzisi bangakhetha ihlangothi elithi "VULA" leswitshi phezulu kwemodyuli ukuvumela umsebenzi wokuthola amaphutha begodu utjengise i-alamu nge- isibani esibomvu se-LED. Umtjhini wokufakwa endaweni>7mA, i-alamu yesekhethi emfitjhani (SC);
Umtjhini wokufaka wendawo ukufaka kokuthintana kutlhoga umsebenzi wokuthola amaphutha (ukuphuka kwentambo, okufitjhani isekhethi), i-resistor ye-22k Ω kufanele ixhunywe ngokufana emaphethelweni womabili ye-switch, begodu i-resistor engu-680 Ω kufanele ixhunywe ngokulandelana (njengombana kutjengiswa emfanekisweni wokufaka iintambo wokuthintana kweswitjhi II).
