introduction：In general industrial production sites，Eddy current access switches and capacitive access switches are usually used。Because these two proximity switches have lower environmental requirements。 When the object to be measured is a conductive object or an object that can be fixed to a metal object，Generally, vortex proximity switches are used，Because of its high response frequency、Good resistance to environmental interference、Wide application range、Lower price。 If the measured object is non-metallic（Or metal）、Liquid level height、Powder height、plastic、tobacco。Capacitive proximity switch should be used。The response frequency of this switch is low，But stable。Environmental factors should be considered during installation。

introduction：Division time，Loosen the spindle locking handle beforehand，Re-lock after indexing，But when machining the helical workpiece，Because the dividing head spindle should be rotated during the workpiece process，So you cant lock the spindle。To approach insist it clean，Before use, the bottom surface of the device, the spindle cone hole and the milling machine table should be wiped clean。Check time，The exposed metal surface should be coated with oil to prevent rust。 Always pay attention to the local smoothness of the dividing head，And follow the rules set out in the book，Refuel regularly。When holding the workpiece at the indexing head，To lock the dividing head spindle first。Do not exert too much force when tightening，Never hit the workpiece hard。Division time，Its usually shaken in a clockwise direction，In the process of shaking，Be as constant and even as possible。Once the position is over, the dividing handle should be returned more than half a turn to eliminate the gap，Then gradually insert the positioning pin in the

introduction：Installation tips on switch panel 1、The installation position of the switch panel cannot have more than two tiles，And try to make it installed in the middle of the tile。 2、When the bottom box of the switch panel is opened，The border cannot be larger than the bottom box2mmabove，You cant make a round hole。This will ensure that the switch is installed later、socket，Bottom box as flat as possible with tile，Later installation will not need to find a longer screw，It cannot be installed on the flower piece and waist line of the tile。 3、To make a hole in the faucet, you must make a round hole，Do not make square holes，And its not gonna work"U"type，The size of the opening shall not exceed the diameter of the pipe2mmabove，And the edge of the water outlet must also be flush with the tile。

introduction：indexingz=35。The number of revolutions of the handle at each indexing is： n=40/z=40/35=1again1/7。That is, once every minute，Handle needs to be turned1again1/7 turn。this1/7The rotation is controlled by the index dial，The general dividing head is equipped with two dividing plates。There are many holes on both sides of the index plate，The number of holes in each ring is different，But the hole spacing on the same hole ring is the same。 The number of holes in each circle on the front of the first index plate is24、25、28、30、34、37；The reverse side is38、39、41、42、43，The number of holes in each circle on the front of the second dividing plate is46、47、49、51、53、54；The reverse are respectively57、58、59、62、66。Simple indexing time，The index plate is fixed。At this point, pull out the positioning pin on the index plate，Adjust the number of holes to7Multiple of the holes on the ring，namely28、42、49Both can。If you choose42Hole number，namely1/7=6/42。therefore，Division time，Once the handle is turned，The number of further holes is42Tu

introduction：Input overvoltage The input parameters of the power mode are abnormal——Input overvoltage。This abnormally light will cause the system to fail to work properly，If its heavy, itll burn the circuit。So what are the reasons for the high input voltage？ The output end is suspended or not loaded； The output load is light. Procedure，Lighter than10%Rated load of； The input voltage is high or interferes with the input voltage。 For this kind of problem，This can be done by adjusting the load on the output or by adjusting the input voltage range，The details are as follows： Make sure the output is not less than less10%Rated load of，If the actual circuit operation will have no-load phenomenon，Right at the output and connected to a rated power10%Dummy load of； Change the input voltage within a reasonable range，When there is interference voltage, consider merging at the input endTVSTube or pressure regulator。
