Working principle of the high/low alarm control pump for 2 relays in the secondary circuit table
Thread Content
I’m new to this; the secondary instrument has two relays for high/low alarms, and I want to control two pumps. I’m not sure if this is possible, and I also don’t know how to set these values How does it work? Thank you!
It’s achievable. A relatively simple circuit process. There isn’t a very complex logical process involved.
