Txheej txheem cej luam
Lub thaiv kev nyab xeeb cais nrog lub qhov hloov pauv nkag mus rau hauv relay, uas cais thiab xa cov teeb liab nkag los ntawm cov neeg sib cuag hloov pauv lossis cov qhov sib thooj hauv thaj chaw muaj kev phom sij mus rau thaj chaw nyab xeeb nrog lub relay tso zis los ntawm lub thaiv kev nyab xeeb. Kev kuaj pom qhov txhaum ntawm kab yog ua tiav los ntawm LED nyob rau sab saum toj ntawm lub module. Lub dial switch ntawm lub module yog siv los teeb tsa kev nkag thiab tso zis hauv-theem lossis rov qab tswj hwm, nrog rau kev qhib lossis kaw lub luag haujlwm ceeb toom qhia txog kab txhaum.
Cov khoom no xav tau lub hwj chim ywj pheej, nrog rau lub hwj chim cais, cov khoom nkag, thiab cov qhov tso zis.
