In the field of industrial automation, recorder products are mainly used in the display, recording and control of field process parameters such as temperature, pressure, flow, and liquid level. 产品显示出越来越明显的优越性。 With the development of electronic technology, the new paperless recorder products show more and more obvious advantages. (1) No mechanical moving parts, less maintenance during use: Since a paper recorder needs a servo drive mechanism to move the recording pen and recording paper, mechanical aging will occur for a long time, causing paper jams and adjustment of the recording pen, etc. The data of the paperless recorder is recorded in the electronic chip and displayed and flipped through the liquid crystal display, so there are no such maintenance problems. (2) The data can be transferred to a computer for further data storage and analysis: historical data stored in a memory chip (data is not lost when power is lost) in a paperless recorder can use a U disk (some companies use Floppy disk or CF card, reading the data is a little more troublesome) Copy the historical data through the USB data port on the meter, and then use the analysis software provided by the paperless recorder manufacturer to read and analyze the data in the U disk. (3) Universal input signal function: Due to the advancement of chip technology, the new paperless recorder products have a variety of standard field instrument signal direct access and strong versatility, such as 0 ～ 5V, 1 ～ 5V, 0 ～ 10mA , 4 ～ 20mA (two-wire system), 4 ～ 20mA (active), Cu50, PT100, resistance (0-400Ω), B, S, K, E, J, T and other signals can be directly connected, software setting Just fine. Eliminates the cost of temperature transmitters, field instrument power, etc. (4) Large-capacity, long-term data recording function: Due to the development of new memory chip technology, large-capacity memory chips are becoming smaller and smaller, and the capacity is increasing. It is possible that, for example, the internal storage capacity of our color paperless recorders can reach 248M, and the recording time can reach more than 10 years (the recording interval is once every 4 minutes). (5) Communication function: Most paperless recorder products also have a communication function, which can form a data communication network with industrial computers. (6) Printing function: Some paperless recorder products also have a built-in printer driver, which can directly connect to a miniature printer to print history or real-time data reports, curves, etc. (7) Chinese tag and logo: The new domestic paperless recorder products have a built-in Chinese character library, which can set Chinese tag and logo.
常见故障及处理方法 Common failures of paperless recorders and their solutions
1. The meter does not work when it is powered on.
A. Check whether the instrument 220V power terminal wiring is correct
B. Check whether the instrument fuse is blown;
C. Unscrew the fixing screw behind the meter, pull out the watch core from the front, and check whether the cable between the power board and the main board is properly connected.
2. The LCD backlight is on, but no characters or curves are displayed.
Check the meter to see if the cables are connected properly.
3, the channel does not count, that is to change the channel signal value, the channel display value does not change.
A. Use a multimeter to measure whether the signal is normal on the terminal;
B. Check whether the channel module switches and signal types are set correctly;
C. Open the case and check whether the channel signal cable is connected properly.
4. The channel measurement value is inaccurate.
A. Check whether the signal type setting in the channel parameter setting is consistent with the actual access signal type;
B. Whether the channel module switch setting is consistent with the call signal type;
C. Check whether the signal wiring is correct and the signal cable is in good contact;
D. After confirming that there is no problem above, re-calibrate the meter (note that the accuracy of the signal source must be higher than 0.1%). If the meter calibration is abnormal (cannot be calibrated), or the calibration is normal but the channel measurement is still abnormal, please contact the manufacturer.
