Time relay product operation in the digital tube display jumble, what is the cause of zero? Cause (analysis) : the clearing line, pause line and control signal line of products are twisted together with the power line. Solution: The zero clearing line, pause line and control signal line should be separated from the power line.

Time relay products have a display when powered on, but do not walk the word (no delay) or delay time (time base) is wrong. 1, preset the digital dip on the product panel; 2, adjust the time base; 3, select the product with the right delay range; 4, the product can not set and adjust the delay of the product during the power-on process, if there is such a need to order the product should be explained.

Time relay products are energized without display, or only show a certain segment or a certain point? 1, strictly according to the wiring diagram of the product, and to confirm which ports can be connected to voltage signals, which ports are switching signals. At the same time, after the product with the base is connected to the line, it must be confirmed that the orientation can be inserted before the insertion, and it can not be inserted by excessive force. If the insertion feels that the product should be used very strongly, the product should be re-inserted at this time.

After the meter counter is powered on, it shows zero. How to do if it does not count? Sensor (photoelectric switch or proximity switch) selection is not correct, the counter meter usually uses DC DC6-36V three-wire PNP normally open photoelectric switch or proximity switch (such as: LJA12M-5P1 or LJA18M-10P1); If you choose NPN normally open type or AC AC90-250V or DC DC6-36V two-wire photoelectric switch proximity switch definitely does not count

The meter counter does not show what is the problem, how to do? First of all, determine whether the power terminal is connected, usually ①, ② or ②, ⑦ power supply, when wiring must see clearly the mark on the base and shell, the wrong connection will burn the product is not displayed, and must see whether it is AC220V or AC380V, or DC24V?

Some problems should be paid attention to during the use of modules 1, thyristor module protection: ◎ Because the breakdown voltage of the thyristor is close to the working voltage, the overvoltage generated in the line is easy to cause the device voltage breakdown. The external causes of overvoltage are mainly lightning strikes, violent fluctuations or interference of power grid voltage.
