this isnt an audio project - but i dont know where else to turn.
I'm trying to install a 3-wire start-stop circuit to a variable frequency drive.
Its described as a simple latching circuit, and is the first diagram shown here:
http://support.automationdirect.com/docs/hitachi_threewire.pdfcorrect me if im wrong, but the circuit shown describes the following:
1. the circle with 'run' in it is a 24V coil that activates the normally open terminals (that look like a capacitor) and are labeled 'run'
2. diode should probably be a simple 1W basic diode for this basic control circuit? they spec belden 18GA for control wiring
3. manually closing the circuit between 'P24' and 'IN1' causes CM1 to energize the coil, latching the run relay until the stop button breaks it.
thanks so much!
