Hi all,

I purchased a Milwaukee MA957 regulator from the local distrubutor in Australia late last December. This model is the 240v European model, as it is terminated with a 2 pin European power plug. I had to purchase a plug convertor for it to adapt to our power standards. I have followed the provided instructions step by step.

Unfortunately, out of the box, the solenoid appeared to be faulty. It would switch off without warning. Sometimes it would run for ten minutes and switch off, other times it would run for six hours then switch off. It would also make random clicking noises from the solenoid. To get it running again, I simply had to remove it from the power point, and plug it back in again. I tried another brand of convertor, but this didn't make a difference. I recently sent the unit back to the distributor here in Australia as faulty, and they quickly sent me a brand new replacement.

I've taken the brand new replacement out of the box, and this one has exactly the same issue. The solenoid makes a clicking sound for a while and then switches off at random times, even though it's plugged in to the power. It was also leaking from the base of the bubble counter. I had to unscrew the bubble counter, reseated the black o-ring and this has fixed the leaking problem.

What I don't understand, is how I can receive two of these units, and have the same indentical problem? I have tried using this unit on different power points throughout my house - this hasn't made a difference.

The distributor here informed me that the MA957 regulator is not designed to run 24hours a day, and mine is probably over heating after a few hours of use. I was under the impression this unit was able to run 24/7 with no problems. Can anyone, especially MA957 owners confirm this?

Since then, I have purchased the SMS122 Digital Controller as recommended as this may solve my issues. I set this up last night, plugged the regulator in to the SMS122 and adjusted the set point. Within one hour, and not reaching the set point, the solenoid had shut off again. Unplugging/plugging it back in again starts it up, but surely this is not how the unit works correctly.

The distributor hee has been very helpful and assured me that the regulators/solenoids I have returned have been working correctly on his configuration connected to a SMS122 Controller.

I was very disappointed when mine started doing the same thing last night after installing the SMS122 Controller.

Can anyone please shed some light on this very strange situation? It has been dragging on for a few months now, and is driving me crazy, haha.

Thanks

I have had problem with mine too the sms122 and the ma957.(us 110v models) I ordered a new pinpoint controller and ordered a new solenoid from Rex. Hopefully milwalkee will repair and send them back in working condition.I plan on selling them,I think the older units were made better!

Thanks for everyones suggestions to date. Still haven't been able to rectify the problem.

DC: I'm running T5 lighting with electronic ballasts, is that what you're talking about?

Update: I've had my setup at a mates place this week, and it has been working fine. This literally blew me away.

It's currently back at my place now, and plugged in to a UPS, and still switching off :( Any ideas?

I'm thinking I may have to replace this regulator with another brand, but don't want to run in to the same situation.

Any help is much appreciated.

Did you try the solenoid not plugged into the UPS?

Also (As DC mentioned), is the T5 a complete unit or are the ballasts mounted remotely?
Is the unit in question neat the remote ballast, or the light fixture fixture (if not remote ballast).

Thanks for your reply tazcrash69

The T5 is a complete unit, and is not plugged in at the same time.

Thanks everyone for their ideas. I've managed to fix the problem over the weekend by purchasing an AquaMedic regulator and solenoid. Works perfectly, no problems, straight forward, looks like a quality product.

The Milwaukee MA957 works perfectly, but just not at my place. Can't explain it.

I am happy with the Aqua Medic product. I will keep an eye on it over the next couple weeks. It's good when something just...works!
