Txheej txheem cej luam
Lub thaiv kev nyab xeeb cais nrog lub luag haujlwm tiv thaiv kev nce siab ntawm cov zis tawm ntawm qhov hloov pauv, uas cais thiab xa cov cim nkag los ntawm cov neeg sib cuag hloov pauv lossis cov hloov pauv ze hauv thaj chaw txaus ntshai mus rau thaj chaw nyab xeeb nrog cov zis tawm ntawm lub thaiv kev nyab xeeb. Kev kuaj pom qhov txhaum ntawm kab yog ua tiav los ntawm qhov tso zis tawm ntawm relay sib cais thiab tso tawm rau ntawm LED sab saum toj ntawm lub module. Lub pob hloov ntawm lub module yog siv los teeb tsa kev nkag thiab tso zis hauv theem lossis rov qab tswj, 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.
| Cov ntaub ntawv nkag mus rau hauv thaj chaw muaj kev phom sij | |
| Lub teeb liab nkag | Hloov cov neeg sib cuag / cov hloov pauv sib thooj |

| Kev hloov pauv tus nqi | |
| Cov yam ntxwv ntawm cov tswv yim / tso zis: | |
| Tam sim no ntawm qhov chaw nkag | > 2.1mA, qhov tso zis kaw, qhia ON; Thaum |
| Cov zis feem ntau "Qhib" / "Kaw" kev tswj hwm kev hloov pauv tiv tauj: | Thaum lub khawm hloov K1 nyob rau sab "ON", qhov tso zis relay yog "Kaw ib txwm". Thaum lub khawm hloov K1 nyob rau ntawm sab "OFF", qhov tso zis relay yog "Qhib li qub". Thaum lub khawm hloov K2 nyob rau sab "ON", lub voj voog xaiv qhia txog lub teeb liab LFD lub tswb muaj nuj nqi. |

Lus Cim: Lub hwj chim ntawm lub tsheb ciav hlau fais fab yog ib qho kev xaiv ua haujlwm. Cov neeg siv yuav tsum tau qhia kom meej hom kev muab hluav taws xob thaum xaj khoom. Thov saib daim ntawv txuas ntawm nplooj ntawv 89.
Kev Tshawb Pom Kab Txhaum (LFD)
Cov neeg siv tuaj yeem xaiv sab "ON" ntawm qhov hloov pauv nyob rau sab saum toj ntawm lub module kom ua kom muaj nuj nqi nrhiav qhov txhaum thiab qhia lub tswb ceeb toom los ntawm teeb liab LED. Tam sim no nkag mus rau hauv qhov chaw> 7mA, lub tswb ceeb toom luv luv (SC); Tam sim no ntawm qhov chaw nkag Kev nkag mus rau hauv kev sib cuag yuav tsum muaj qhov ua haujlwm nrhiav qhov txhaum (hlau tawg, luv luv Circuit Court), ib tug 22k Ω resistor yuav tsum tau txuas nrog parallel ntawm ob qho kawg ntawm qhov hloov, thiab 680 Ω resistor yuav tsum txuas nrog series (raws li qhia nyob rau hauv daim duab qhia txog kev sib txuas ntawm qhov hloov pauv II).
