2.1.2. Qhov txwv qis tshaj plaws tsis qis dua -5 ° Cc. Tus nqi nruab nrab hauv 24 teev tsis tshaj + 35 ° C.
2.1.3. Txwv qhov kub ua haujlwm -25 ° C ~ + 70 ° C

2.2 Qhov Siab Qhov siab ntawm qhov chaw teeb tsa tsis tshaj 2000 meters.
2.3 Cov Huab Cua
2.3.1. Thaum qhov kub ntawm huab cua yog +40 ° C, qhov av noo ntawm huab cua tsis pub tshaj 50%, thiab qhov av noo tuaj yeem siab dua ntawm qhov kub qis dua.
2.3.2. Thaum qhov kub nruab nrab tsawg kawg nkaus ntawm lub hli ntub tshaj plaws yog 25 ° C, qhov nruab nrab ntawm cov av noo txhua hli yog 90%.
2.3.3. Kev ua kom cov dej noo ntawm qhov chaw ntawm cov khoom vim yog qhov kub thiab txias tau raug coj los xav.

2.4 Qib Kev Ua Phem
2.4.1 Cov khoom tiv thaiv siv rau theem 2 ntawm kev ua qias tuaj.

2.5 Pawg Kev Teeb tsa
2.5.1 Pawg kev teeb tsa yog Chav Kawm ll thiab lll.

Cov yam ntxwv ntawm cov khoom

1. Muaj peev xwm faib ua pawg siab.
2.RS485 kev sib txuas lus, chaw taws teeb hloov/kaw, teeb tsa cov kev teeb tsa.
3. Xauv thiab qhib qhov chaw thaum lub sijhawm txij nkawm.
4. Kev tiv thaiv tsis muaj zog: Tus nqi ua haujlwm tsis muaj zog tuaj yeem teeb tsa, thiab qhov ua haujlwm tsis muaj zog tuaj yeem raug tua.
5. Kev poob ntawm kev tiv thaiv voltage: Thaum lub undervoltage function qhib, nws muaj kev poob ntawm kev tiv thaiv voltage, uas yog lub zog mus ncig, thiab cov khoom tsis tuaj yeem kaw manually lub sijhawm no.
6. Kev teeb tsa tes/Tsis siv neeg: Hom kev teeb tsa tes lossis tsis siv neeg tuaj yeem teeb tsa tau.
7. Lub sijhawm tiag tiag voltage, curent thiab fais fab tuaj yeem nyeem tau,
8. Lub tshuab hluav taws xob yuav tsum tau teeb tsa ntsug ntawm txoj kev teeb tsa, thiab txoj kev teeb tsa tau ruaj ntseg rau lub rooj tsavxwm roj hmab lossis phaj hlau nrog M5 ntsia hlau.
