1, Txuas kab hluav taws xob mus rau cov ntsia hlau terminals AC, GND lossis DC hauv lub transmitter.Tnws av terminal grounds lub ntsuas, uas yog yuav tsum tau rau kev nyab xeebkev ua haujlwm.
DC fais fab kev sib txuas: TF1100 tuaj yeem ua haujlwm los ntawm 9-28 VDC qhov chaw, ntev li ntev tauqhov chaw muaj peev xwm muab qhov tsawg kawg nkaus ntawm 3 Watts.
CEEB TOOM: Cov cuab yeej no yuav tsum muaj cov kab hluav taws xob huv huv.Tsis txhob siv lub tshuab no raucircuits nrog cov khoom nrov nrov (piv txwv li, lub teeb fluorescent, relays, compressors, lossis hloov pauvzaus drives).Nws raug nquahu kom tsis txhob khiav kab hluav taws xob nrog lwm cov teeb liab xaim hauvtib lub tais hluav taws xob lossis cov kav dej.
2, Txuas 4 ~ 20mA cov xov hlau rau qhov tsim nyog (4 ~ 20mA + -) (Cov zis 4-20 mA tsisyuav tsum tau lub hwj chim los ntawm ib qho hluav taws xob DC sab nraud)
3, PLUS tuaj yeem teeb tsa raws li Pluse thiab zaus.RELAY tuaj yeem teeb tsa liPulse tso zis tsuas yog rau Flow Rate Output.
Cov zis mem tes yog siv los xa cov ntaub ntawv mus rau lwm lub txee thiab PID systemslos ntawm ib tug zaus tso zis uas yog proportional rau system flow rate.Qhov tso zis ntau zausntawm Pulse yog 0-9,999 Hz.
Hom pulse tso zis yog ib qho qhib-collector transistor (OCT) hom uas yuav tsum tau muaj sab nraudlub zog qhov chaw thiab rub-up resistor.Sab nraud DC fais fab mov yog nyob ntawm Pulse Outputreceiver, 5-24V yog tso cai.
4, Relay "+, -", tsuas yog Rau Totalizer Output lossis Relay Tswb tso zis.
Thaum lub tshuab xa hluav taws xob tau qhib, qhov "RELAY +, -" cov zis feem ntau qhib lub xeev.Thaum lub relay siv rau tag nrho cov zis tawm, txuas lub davhlau ya nyob twg "RELAY + -", xaiv qhovsib thooj totalizer nyob rau hauv Ntawv Qhia 79, thiab teeb tsa qhov tsawg kawg nkaus zaub totalizer increments .Txhua zaus tus totalizer nce tus nqi teem lub relay kaw ib zaug.
Thaum lub relay siv rau lub tswb tawm, txuas lub davhlau ya nyob twg "RELAY + -", xaiv qhovcov khoom sib xws, nws tuaj yeem siv rau ntau lub tswb.Piv txwv li,xaiv "Tswb #1", teem "Tswb #1 Tus nqi qis", thiab teeb "Tswb #1 Tus nqi siab".Thaum qhov ntws yog nruab nrab ntawm tus nqi qis thiab tus nqi siab, lub relay qhib lub xeev,thiab thaum qhov ntws qis dua "Low Value", lossis siab dua "High Value", tus relay yogkaw lub xeev.
5, RS232C lossis RS485 thaiv:
TF1100 Series muab RS232C lossis RS485 kev sib txuas lus tso zis raws li tus neeg siv kev xaiv.
6, RS485 (Modbus-RTU) txuas:
TF1100 series default Modbus tso zis yog Modbus-RTU raws tu qauv, Modbus-ASCII raws tu qauvtuaj yeem xaiv tau.
Thaum txuas xov hluav taws xob, lub davhlau ya nyob twg "D +" txuas nrog modbus "A", thiab "D-"Lub davhlau ya nyob twg txuas nrog modbus "B".(Ntau cov ntsiab lus hauv APPENDIX 4 MODBUS-RTUTXOJ CAI TXUJ CI)
