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 automationdirect VFD that drives a main motor. A contractor and motor that dirves the auger and a new micro830 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.
Im 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.
