Hey Guys, thank you for the feedback. OEE refers to Overall Equipment Effectiveness

Hello Everyone, I am part of a team looking into acquiring an OEE software for our facility. Does anyone have any advice on which OEE I should be looking at, and why? What are the requirements you wish you have with your current OEE? Thank you.

Thank you for the feedback @jraef. You are right in saying it is a Motor that is driving a brush under a conveyor belt. So does the UF fault renders the VFD defective? Which brands would be recommend?

Hello, We are currently using a AC Tech SF450 VFD to drive a 5HP conveyor brush motor. We have been having recurring "UF" faults that basically renders the drives useless. A quick troubleshot suggests the fault is a result of a ground fault. Any thoughts on avoiding ground faults on a VFD...

Thank you itsmoked. I'll have the Electricians do the necessary check, and will get back to you on what we find.

Hello fellow Engineers, Our 1000 ton carrier chiller has been experiencing recurring chronic VFD fault when the unit goes into or comes out of a minimum load period. Any ideas on what might be going on?The fault showing is Pre-charge Open – Check contacts, wiring, resistance, and parameters.

Thank you for all of your replies. I really appreciate you taking the time to reply. I will take all your advice into consideration.

The vents are always open. The air that is being fed into the enclosure goes out through the vent. I do like the idea of an interlocking system that will alert us if the door is open. Thank you Ed

Hi EdStainless, The box is rated for NEMA 4x. The enclosure has two vents on the front. The duct that supplies air is located on the bottom of the enclosure. Regards, Mr Thttps://files.engineering.com/getfile.aspx?folder=d2b43003-6a2c-4630-9c9e-bd36ee98eb07&file=IMG_0263.jpg

No Sir, the supply air is not even filtered at all. Also I did observed when I did the initial inspection, that the door was not completely closed.

Hello Everyone, We have an Electrical enclosure that is located in a very silica dusty area. The enclosure is under positive pressure, but for some reason,we are still having dust accumulation. Any ideas on what might be going on? Regards, Mr T Reliability Engineer
