I am trying to combine an auger filler with a packing machine. Neither of the 2 machines have a proper safety circuit. The power feed in is 230volt. I have a AC Tech VFD that drives a main motor. A contractor and motor that dirves the auger and a SIMATIC S7-200 PLC that I set up to receive a signal from the packing machine to release the auger brake. Im not very experience with this type of work but I have the machines working together. Now I would like to finish up the machine by installing all components into the panel & create the safety stops. I would install an Estop switch, main power switch & switch for the auger. I'm having a really hard time figuring out what I would use to power the coils on the estop relay. I have the 230 volt hots, but no neutral. I also have the 24v from the VFD. I would assume I use the 24v, but the schematic I look at for the estop relays show a line voltage including a neutral. Any guidance would be appreciated. |
