Angry light with motion sensor on 220 volt single phase works intermittantly

i changed the light fixture in a 220 volt single phase light from a metal hallide to a 6 tube fluorescent with a motion sensor. The light and sensor work correctly ( comes on when you flip the switch and trips off after no motion for a period of time). The issue is that after you turn it off and leave it it will not come on with the switch. You have to flip the breaker, then it works. I assume they only switched one of the legs of the 220 volt power. Could that be affecting the motion sensor and preventing the light from coming on? or could it be that the motion sensor is not on the leg that is switched causing an issue with the motion sensor?

Welcome to the forums.

Motion sensors need power all the time to work.
Can you leave the switch turned on and then let the sensor do its job ?

Pete, The motion sensor is being used more like a fail safe shut off since this is in a horse barn with relativily low use in this area. I wonder if the intermittent issue is because it is switching the leg without the motion sensor.
Could that be the case?

Thanks!

When you are working with 240v...... there are two hot legs. Shutting either off will leave the other live. Every motion sensor I've worked with requires 240v to operate normally. Turning the switch off removes the 240v from the sensor.

If yours is something different.... leave a link to it.

Some motion sensors need a quick flick of the switch to make them come on and bypass the motion sensor. Simply turning them on from off sets it to sensor mode. The light only comes on when motion or heat is sensed.
From the on position a quick off/on flick bypasses the sensor and the light stays on.
