Ukuhlaziywa kwephutha nokususwa kwesithando somlilo esihlakaniphile

A: Vula i-thermocouple: cisha ugesi bese uvula ikhava yangemuva yesithando somlilo:

(1) Hlola ukuthi ingabe inathi exhuma iposi lokugcina le-thermocouple kanye nocingo oluholayo lwe-thermocouple luqinisiwe yini, bese uqinisekisa ukuthi laba bobabili bayaxhumana yini.

(2) Hlola ukuthi inzwa ye-thermocouple uqobo inaso yini isimo sesekethe esivulekile. (Ingahlolwa ngemitha, njenge-multimeter)

(3) Bheka ukuthi izixhumi, izikhungo zokuxhuma izintambo, kanye nama-adaptha phakathi komugqa wokugcina we-thermocouple nebhodi lesifunda kuvulekile noma kuvulekile impela. Kwesinye isikhathi ingabuyiselwa kwesejwayelekile ngemuva kokuyixhuma iphinde iyikhiphe futhi. Lokhu kungenxa yenqubo yokufaka noma ungqimba lwengqimba ye-oxide ebonakala lapho i-terminal isezingeni lokushisa eliphezulu isikhathi eside.

(4) Kubangelwa amasiginali wokuphazamiseka aqinile, lolu hlobo lwesimo aluvamile.

B: Thermocouple connection reversed: Turn off the power supply, open the back cover of the muffle furnace, and check whether the polarity of the thermocouple end and the polarity of the thermocouple input port of the controller are the same after the line is connected. (Available visual inspection method and instrument test method)

C: Communication interruption: Check whether the external line interface of the controller is disconnected or has poor contact (such as the connection of the nine-pin serial port, aviation plug, etc.), and ensure that the connection is reliable and the contact is good.

D: Umsebenzi wokuthinta awuvumelekile:

(1) Hlola ukuthi ikhebuli yokubonisa ixhumana kahle yini. Vula igobolondo lesilawuli bese uhlola ukuthi ngabe ikhebuli yokubonisa phakathi kwesikrini sokubonisa nebhodi lokulawula selindala noma alinabo oxhumana nabo abampofu. Kwesinye isikhathi i-interface emaphethelweni womabili wekhebula lokubonisa ingabuyiselwa kokujwayelekile ngemuva kokuyixhuma nokuyikhipha kanye.

(2) Khombisa izinkinga zekhebula noma izinkinga zokubonisa. Xhumana nomenzi ukuze ungene esikhundleni.

E: Akukho ukubonisa kusibonisi (isikrini esimnyama):

(1) Hlola ukuthi ngabe i-interface yokuphakelwa kwamandla kwesilawuli icishiwe noma ayisebenzi.

(2) Bheka ukuthi ukukhanya kwesikhombi samandla ngaphakathi kwesilawuli kuvuliwe yini, uma kuvuliwe, hlola ukuthi ikhebuli ekhombisa ayilungile yini; uma isibonakaliso sangaphakathi sivuliwe (ingaphakathi limnyama), lisombulule ngokuya ngezindlela ezilandelayo.

(3) Check whether there is a short circuit inside the controller. Disconnect the serial port cable on the back of the controller, use a meter to test whether there is a short circuit between the 6 pins and 9 pins of the serial port. Make sure that there is no internal short circuit (that is, there is no short circuit between the 6 pins and 9 pins of the serial port on the back of the controller. Short-circuit phenomenon).

(4) Bheka ukuthi amandla okushintsha anawo yini umphumela we-DC 5V. Nqamula ikhebula le-serial port ngemuva kwesilawuli, vula ugesi, bese usebenzisa imitha ukuhlola ukuthi ngabe amandla kagesi ashintshayo akhipha i-DC 5V, noma ubheke ukuthi isibani sesikhombisi esiseduze kokunikezwa kwamandla sikhanyisiwe yini. Qiniseka ukuthi amandla okukhipha wokunikezwa kwamandla ajwayelekile.

(5) Check whether the power supply circuit of the controller is broken (instrument test).

(6) Check whether the internal connector of the controller is off or loose.

(7) Ukwehluleka okuphelele kwesekethe, xhumana nomkhiqizi ukuze akususe noma akubuyisele esikhundleni.

F: Fuzzy or severely abnormal colors appear on the display:

(2) Khombisa izinkinga zekhebula noma izinkinga zokubonisa. Xhumana nomenzi ukuze ungene esikhundleni.

G: Isilawuli siqala kabusha kaninginingi: hlola ukuthi ukuphuma kwe-5V DC kokunikezwa kwamandla kuzinzile (shintsha ngaphakathi kwe- ± 0.2V). Ngokuvamile, kubangelwa ibanga elikhulu lokuxhuma kwamandla kagesi okukhipha, ukungazinzi, noma ukulimala kwezingxenye zangaphakathi.

H: Ukushintsha amandla kagesi akunakho okukhiphayo kwe-DC5V (isibani senkomba sicishiwe):

(1) Ensure that the load is not short-circuited. Disconnect the serial port cable on the back of the controller, use a meter to test whether there is a short circuit between the 6 pins and 9 pins of the serial port. Make sure that there is no internal short circuit (that is, there is no short circuit between the 6 pins and 9 pins of the serial port on the back of the controller. Short-circuit phenomenon).

(2) Qinisekisa ukuthi i-terminal yokufaka ine-AC (170V ～ 250) V, 50Hz voltage input.

(3) Ukunikezwa kwamandla okushintsha uqobo kulimele. Xhumana nomenzi ukuze ususe noma ungene esikhundleni.

Mina: Ukushisa kwesithando somlilo kukhuphuka ngaphansi kwezinga lokushisa elibekiwe isikhathi eside ekuqaleni kokuhlolwa:

(1) Intambo yesithando somlilo ivulekile. Hlola ukuthi ingabe ucingo lwesithando somlilo luvulekile noma amandla omthwalo awanele (iqoqo lezintambo zesithando liphukile). Ukuphikiswa kocingo lwesithando kungahlolwa ngensimbi, evame ukuba ngama-ohm ayi-10-15.

(2) Ukudluliswa kombuso okuqinile kushisiwe noma konakele. Hlola ukuthi ukudluliswa kombuso okuqinile kulimele yini noma izintambo zokulawula azixhumani kahle.

(3) Amandla kagesi aphansi kakhulu.

J: Akukho ukushisa noma akukho ukushisa

(1) Intambo yesithando somlilo ivulekile. Hlola ukuthi ingabe ucingo lwesithando luvulekile, vula ikhava yangemuva yesithando somlilo, bese uhlola ukumelana kocingo lwesithando ngemitha. Imvamisa, icishe ibe ngu-10-15 ohms. (Bheka ukuthi ukuhlangana kwamatheminali kuxhumana naye onokwethenjelwa)

(2) Ukudluliswa kombuso okuqinile kushisiwe noma konakele. Hlola ukuthi ukudluliswa kombuso okuqinile kulimele yini noma izintambo zokulawula azixhumani kahle.

(3) The thermocouple has an open circuit. Check if there is an open circuit, then restart the device after power off

(4) Isifunda sokulawula sinamaphutha. Hlola ukuthi umugqa wedatha we-serial port uxhunywe ngokuthembekile nangokuqinile, futhi uhlole ukuthi ngabe isikhombimsebenzisi sokulawula umugqa wokudlulisela isimo siqinile yini

(5) Inkinga yesilawuli. Xhumana nomkhiqizi.

K: Enclosure is charged:

(1) Bheka ukuthi ulayini wokuphakelwa kwamandla ulimele noma unoxhumano lokudweba ngocingo necala.

(2) Bheka ukuthi ngabe ucingo lwaphansi lokuphakelwa kwamandla luthintana naye ngokuthembekile noma alukho.

(3) Umoya owomile nogesi ongaguquguquki.
