Need help with motor control circuit

Post by baddog »

I am working on a linear actuator (which is basically a electric screw press). I am having to wire up my own motor control circuit. I have attached the factory schematic, but I am having trouble identifying a few components. There are several components that look like capacitor symbols (K1 (2 each) & K2 (2 each)) but they don't list any specifications (any help appreciated on sizing). Also, there is two other items labeled K1 and K2 that I can't identify the symbols (are they the relays discussed in Note #4 at the bottom of the schematic?). I have a fairly basic electronics background so I could sure use a little help. I already have the motor capicator shown (35 uf 360 volts). I can figure out the DPDT switch). Image

Hi.
Industrial electric diagrams show relay contacts with the same symbol as capacitors.
Cannot view your schematic, but chances are K1 are contacts for relay 1, similar for K2.

Hey, thanks for the reply. I didn't have the image posted until a few minutes after I made the post. It should be visible now. Your response makes sense. The two other symbols that don't look like capacitor symbols kind of look like coils, so those would probably be the coils in the relays. So, are all the K1's (3 each (2 contacts and 1 coil) part (connections) of one of the relays, and all of the K2's part of the second relay, Or ??? Thanks.
