Contactor to DOL starter & switches
Former Community Member
I have a DOL starter (https://docs.rs-online.com/c08c/0900766b81586106.pdf for reference) that I want to connect to my ac motor. I understand that the dol starter has a built-in contactor. I want to connect two other switches, a tilt and a proximity switch. Is it possible to connect these two switches to this DOL? If not how would I go about this?
If you look at the datasheet link I posted above, the circuit shows the stop buttons need to break to release the contactor - so you add another switch in series with the stop button that also breaks contact in the 'fault' condition. Then when either of them opens the loop, the contactor loses its supply and stops the motor.
You may need to use a relay to invert the sense of the tilt switch it it makes contact when in the fault state you wish to detect.
