Question for valveman

[Banjo Bud]

I have a cycle sensor (which saved my pump a week ago). I want to put a switch near my pump to turn it off & on instead of doing it at the beaker. Power now goes to the sensor, then to the pump. Should I put the switch before the sensor, or between the sensor and pump? Or maybe it doesn’t matter. It would be easier to wire if the switch was between the sensor and pump. It’s a shallow well pump that is in my garage.

Since you have the sensor, which only runs on 240V, I assume your pump runs on 240V too? You should consider using a double-pole toggle switch for that. That will kill both hots to the pump.

Should I put the switch before the sensor

Yes, you need to kill the power to the sensor and as Chucky_ott mentioned, you should use a double-pole switch.

It seems to me that the Cycle Sensor L2out and L1out go to the pressure switch which feeds the pump motor. So putting a toggle switch between the pressure switch and the motor should not be a problem.

So putting a toggle switch between the pressure switch and the motor should not be a problem.

I would assume that the Cycle Sensor is wired before the pressure switch otherwise the pressure switch will reset the Cycle Sensor every time the pressure switch cycles. The on/off switch needs to be between the breaker and the Cycle Sensor.

Yes.

The on/off switch needs to be between the breaker and the Cycle Sensor.

I don't follow that logic. Before or after would turn off the pump. The purpose of this proposed switch would be to turn off the pump.

I assume the OP wants to also reset the Cycle Sensor which can easily be done by cycling power.

 

[Reach4]

I did/do not assume that.

 

[Banjo Bud]

I am the OP. No, I don’t necessarily need or want to turn off the sensor. Turning off the pump is sufficient. Just to work on it now and then if I need to. And I have a DPDT switch. I know how to wire so that’s no problem. I’m still thinking In my case it really doesn’t matter if the switch is before or after the sensor. As long as it turns the pump off.

Sorry for the delay. Had the granddaughter all week.

You can cut the line before or after the Cycle Sensor if you want. The Cycle Sensor also only cuts one of the two legs. So, if you use a single throw switch prior to the Cycle Sensor, it needs to cut the other leg. Other wise you will get 115V feeding back and the lights on the Cycle Sensor will flicker. Using a double throw switch is best.

If you cut the lines after the Cycle Sensor, it may see it as low amperage and trip off on Dry run. Also, if you turn the switch on and off too quickly, it will trip out on Rapid Cycle. Either of these trips will require the breaker or reset button to be pushed before the pump will start. A double throw switch on the inlet side of the Cycle Sensor is best.

Thanks valveman.
