3.2 Bonisa ujongano
Emva kokuba isixhobo sivuliwe, ngenisa ujongano lokubonisa ukuqalisa.Njengoko kubonisiwe kuMfanekiso 7:
Umfanekiso 7 ujongano lokuqalisa
Olu jongano kukulinda iiparamitha zesixhobo ukuzinzisa.Ibha yokuskrola phakathi kwe-LCD ibonisa ixesha lokulinda, malunga ne-50s.X% yinkqubela phambili yobaleko lwangoku.Kwikona esezantsi ekunene kwesiboniso lixesha lesixhobo sangoku (eli xesha lingatshintshwa njengoko kufuneka kwimenyu).
Xa ipesenti yexesha lokulinda i-100%, isixhobo siya kungena kwi-interface yokubonisa igesi esweni.Thatha icarbon monoxide njengomzekelo, njengoko kubonisiwe kuMfanekiso 8.
Umzobo 8 esweni iziboniso zegesi
Ukuba ufuna ukujonga iiparamitha zegesi, cofa iqhosha lasekunene.
1) Ujongano lokubonisa:
Bonisa: uhlobo lwegesi, ixabiso lokugxininiswa kwegesi, iyunithi, urhulumente.Njengoko kubonisiwe kuMfanekiso 8.
Xa igesi idlula ekujoliswe kuyo, uhlobo lwe-alamu lweyunithi luya kuboniswa phambi kweyunithi (uhlobo lwe-alarm ye-carbon monoxide, i-hydrogen sulfide kunye negesi evuthayo yinqanaba 1 okanye i-2, ngelixa uhlobo lwe-alarm ye-oksijini umda ophezulu okanye osezantsi), njengoko kubonisiwe kuMfanekiso 9.
Umzobo we-9 ujongano kunye ne-alamu yegesi
1) Ujongano lokubonisa iParameter:
Kwi-interface yokukhangela igesi, cofa ekunene ukuze ungene kwiparameter ye-gas display interface.
Bonisa: uhlobo lwegesi, i-alarm state, ixesha, ixabiso le-alam yenqanaba lokuqala (i-alamu ephantsi ephantsi), ixabiso le-alarm yenqanaba lesibini (i-alarm ephezulu yomlinganiselo), uluhlu, ixabiso le-concentration yegesi yangoku, iyunithi, indawo yegesi.
Xa ucinezela isitshixo (iqhosha lasekunene) phantsi "kokubuyisela", ujongano lokubonisa luya kutshintshela kwi-interface yokubona igesi.
