Bed electrical control technology, as shown in the diagram, ask: if the work station to run at both ends, want to stay for 10 seconds, how to control the design of the circuit?
A time relay in his one normally open contact to coil KM1, KM2 series electric locking loop, that is to say the motion of the platform to end, after the pressure switch, give him a ten seconds delay to contactor inversion of control power, so that we can realize that work Taiwan stop 10 seconds, ten seconds to remember to pay attention to the time relay is reset, the coil circuit loss of electricity, or directly to the other end of the reverse.
Look, your question has hung over here for a long timeNot everyone is not willing to answer your question, but it is troublesome to draw a circuit diagramMoreover, each person to draw a circuit diagram has its own style, to you, you may not understandI suggest you get yourself some small contacts and time relays, and do it yourselfThis kind of knowledge above the textbook can only be realized through practiceHa ha, if I draw the drawings, it is estimated that you do not understandSince I did not learn it in school, I learned it in practice, so it was not standard to draw a circuit diagram
Make your own, do not understand, ask
