I installed a replacement motor run off an existing Eaton S811+ soft starter. The new motor has an internal thermal cutout whereas the old one did not. There are a couple of ways I could tie in the cutout to the general control circuit, but it seems like it may be easier and better to use the options (I/Os) on the soft starter. Is there a standard way of doing this?
I could just have the cutout open either the RUN or ENABLE signal. There are input options for "external trip" or "external e-stop" but the manual says those disable the ramp to stop feature. This is a pump application, and a diaphragm valve needs to close as the motor ramps down.
I'm probably making this more complicated than it needs to be, so I thought I'd ask here for some clarity.
TIA
