1., how to deal with the failure of the intelligent controller?
Answer: if the field controller fails, it can be simply checked according to the user manual. If it is still unable to solve, we should get in touch with our after-sales service department, and provide the fault condition of the faulty meter and the name of the project. Product model, serial number and other related information. Our company will arrange technical engineers to deal with problems on the spot, so as to ensure the safe and stable operation of the user system.
2. how to do the inflexible keys of the field controller?
Answer: normal running time, just press the button in programming, but can not enter the main page, the reason for this situation is to set up a password, enter the password can. If the company is not able to use the company to replace the product normally.
3. what is the analysis of the failure of the communication connection?
Answer: (1) check the correspondence between instrument address and Crisis Address.
(2) check whether the communication rate of instrument is in correspondence with the rate of crisis communication.
(3) check whether the instrument's communication link connection is normal
(4) check whether the work of communication microcomputer is normal
(5) check whether the work of communication conversion equipment is normal
(6) check whether the communication link is single end to earth
(7) the way of communication transmission is matching: data bit matching, stop bit matching, check mode matching.
(8) whether the setting of communication protocol meets the requirements of instrument: function code and memory address.
4., what are the factors that affect the speed of communication and the quality of communication?
Answer: the electromagnetic interference in the field, the quality of the communication link, the processing speed of the microcomputer, the compatibility of the communication physical conversion interface and the selection of the communication cable may affect the communication speed and the quality of communication.
5., why do I use high voltage and high current to use transformers?
Answer: (1) expanded the scope of the use of the instrument. A variety of voltages and currents can be measured as long as the transformer with different voltage variable ratio and variable flow ratio is used with the voltmeter of 100V and the current meter with full current of 5A.
(2) uniform specifications for instruments and relays, easy standardization and mass production.
(3) using the transformer as the intermediate element of the primary circuit and the two circuit, the danger of high voltage is isolated and the influence of the two circuit faults on the one circuit is also prevented.
6. high voltage electrical appliances must meet the conditions?
Answer: A. insulation is safe and reliable.
B. runs at a rated current for a long time and has a short time overload capability.
C. can bear short circuit current thermal effect and electrodynamic effect without damage.
The D. switchgear can be safely and reliably shut down the prescribed current.
E. outdoors should bear certain natural disasters.
