Fault Debugging Cov kauj ruam rau qhov sib txawv siab Transmitter

Fault debugging cov kauj ruam rau pebUPB 5Differential siab transmitter yog raws li nram no:

1. Tshawb xyuas cov khoom siv hluav taws xob

a) seb qhov zoo thiab qhov tsis zoo ntawm cov khoom siv hluav taws xob txuas nrog raug lossis tsis yog.

b) seb lub hwj chim ntawm lub transmitter muaj 24V DC voltage; Nws yuav tsum tau xyuas kom meej tias lub hwj chim mov voltage muab rau lub transmitter yog ntau tshaj los yog sib npaug rau 12V (uas yog, qhov voltage ntawm lub input davhlau ya nyob twg ntawm lub transmitter fais fab mov yog ntau tshaj los yog sib npaug rau 12V).

2. Yog tsis muaj fais fab mov

a) xyuas seb lub Circuit Court puas raug txiav los yog tsis.

b) xyuas seb qhov ntsuas ntsuas puas raug xaiv tsis raug (input impedance yuav tsum tsawg dua lossis sib npaug rau 250Ω) thiab lwm yam.

3. Yog hais tias lub siab transmitter muaj lub taub hau meter, nws yuav tsum tau xyuas seb lub meter taub hau puas puas lawm. Yog hais tias lub meter taub hau puas lawm, Lub header yuav tsum tau hloov.

4. Yog tias muaj teeb meem nrog qhov sib txawv siab siab transmitter, koj tuaj yeem txuas lub ammeter hauv series nrog 24V fais fab Circuit Court los xyuas seb qhov tam sim no zoo li cas. Yog hais tias nws yog ib txwm, nws txhais tau hais tias lub transmitter yog ib txwm. Lub sijhawm no, koj yuav tsum xyuas seb lwm cov twj paj nruag hauv lub voj voog puas zoo li qub.
