Hi Refrigerates Techs,
Anyone discover any malfunction with the Traxoil OM3-120 modules of Emerson / Copeland.
We encounter frequently failures with this oil level modules, and the feedback from the supplier is that humidity enters the modules by the screws of the 2 solenoids what's their failure analyses.
The failures will mostly give a low oil level alarms (when level is fine), and sometimes they really completely broken (No LED's activated anymore) what's gives a big effect on the plant performance.

Modules should have a IP65 rating, but really have my doubts about this rating as units are installed in a clean and dry machine room and still fail on this humidity.
They installed on a skid with several frequency drive controlled DMW Copeland 6TJ1-250X compressor for R507, and there could be a relation with compressor breakdowns as well (unexpected overfilling of the compressor with oil ?)

Thanks your thoughts guys to get this sorted out,
