Chidule
Chotchinga chachitetezo chodzipatula chokhala ndi zotulutsa zolowetsa zosinthira, chomwe chimalekanitsa ndikutumiza zizindikiro zolowera kuchokera ku zolumikizira zosinthira kapena zosinthira zapafupi m'malo oopsa kupita ku malo otetezeka ndi zotumizira zotulutsa kudzera mu chotchinga chachitetezo. Kuzindikira cholakwika cha mzere kumachitika kudzera mu LED pamwamba pa module. Chosinthira choyimbira cha module chimagwiritsidwa ntchito kukhazikitsa zolowetsa ndi zotulutsa mkati mwa gawo kapena kulamulira kobwerera m'mbuyo, komanso kuyatsa kapena kuletsa ntchito yowonetsa alamu yozindikira cholakwika cha mzere.
Chogulitsachi chimafuna magetsi odziyimira pawokha, okhala ndi magetsi odziyimira pawokha, malo olowera, ndi malo otulutsira.

Kuzindikira Cholakwika cha Mzere (LFD)
Ogwiritsa ntchito amatha kusankha mbali ya "ON" ya switch pamwamba pa module kuti muyambitse ntchito yozindikira zolakwika ndikuwonetsa alamu kudzera mu Kuwala kofiira kwa LED. Mphamvu yolowera pamalopo> 7mA, alamu yafupikitsa nthawi (SC);
Mphamvu yolowera pamalopo Kulowetsa kolumikizana kumafuna ntchito yozindikira cholakwika (kusweka kwa waya, kufupika circuit), chotsutsa cha 22k Ω chiyenera kulumikizidwa motsatizana mbali zonse ziwiri ya switch, ndi chotsutsa cha 680 Ω chiyenera kulumikizidwa motsatizana (monga zomwe zawonetsedwa mu chithunzi cha mawaya a switch contact II).
