ibicuruzwa

5 Ibisohoka bisohoka byasuzumwe kandi byemejwe na Factory Mutual nkaho ari Nonincendive. Ibi bivuze ko niba insinga zumurima zafunguwe kubwimpanuka, zigufi, cyangwa zigahagarara kandi HPM ikora mubisanzwe, insinga ntizisohora ingufu zihagije zo gutera inkongi y'umuriro mu kirere cyaka umuriro. Imbonerahamwe 5-3 ni urutonde rwibintu byinjijwe, ibisohoka bisa, hamwe ninjiza ya digitale FTAs ifite ibisubizo bidasobanutse. Na none, mugihe ibyuma bisohora ibyuma bisohoka muburyo bwa digitale FTA iriho nubu na voltage bigarukira kurwego rukwiye kubakoresha, ibisohoka muburyo bwa digitale FTA nayo ishobora gufatwa nkibidashoboka. Umuyoboro wibikoresho hamwe nuburemere (ibipimo byikintu) Kugirango umenye neza ko imirima yumurima idashobora gutwika imyuka yaka umuriro, ingano ya kabili nibipimo byimizigo bigomba kumenyekana no kugenzurwa. Imbonerahamwe 5-3 itanga agaciro ntarengwa kemewe kerekana ibipimo kuri buri FTAs ziri kumeza. Kwemeza amashanyarazi Muri rusange, insinga zumurima mugice cya 2 ahantu hashobora guteza akaga zigomba gukorwa ukurikije code zaho; icyakora, mu nkiko zimwe na zimwe, insinga zidahwitse ntizigomba kubahiriza amategeko asanzwe yo mu cyiciro cya 2, ariko irashobora gukoresha uburyo bwo gukoresha insinga zibereye ahantu hasanzwe. Reba ANSI / ISA S12.12, igice "Ibikoresho by'amashanyarazi byo gukoreshwa mu cyiciro cya I, Igice cya 2 Ahantu hateye akaga." Kugabanya agaciro ka résistoriste Kugeza ubu Agaciro k’urwanya kuri FTAs yatoranijwe kugira ngo hamenyekane imigezi mibi y’umuzunguruko mugace k’akaga kari munsi ya milliamps 150 kubikoresho bisanzwe bikora. Nk’uko bitangazwa na NFPA # 493, Ibikoresho byizewe byifashishwa mu gice cya 1 Ahantu hateye akaga, milliamps 150 ziva mu isoko rya 24 Vdc ziri munsi y’umuriro w’umuzunguruko urwanya imyuka yo mu matsinda A kugeza D ibidukikije.
