I talked with Basler. They actually proposed the new settings and when I asked for reason or their basis for the values being recommended they said it's from experience. I am not convinced by this response. Machine is quite old, more than 20 years for sure but inspection(Mechanical and...

I have already given my stance to the Management that OEM must be consulted and risk is involved if they go ahead. This is for my own technical understanding.

Hey Phil, Well, we did not observe any increase in Vibration magnitude of any proximity sensors prior to trip. Actually it would have been so much easier had we configured trending on these values. Unfortunately in the packaged unit only events triggering is captured i.e. if vibration increases...

Happy Anniversary Phil! May your family always find love in their hearts and blessings on their table. Interesting case study you shared. Thanks. In our case, we had proximity and seismic probes both installed on bearings, so had it been Morton, the proximity probes would have picked up...

Hey Phil, Sorry for the late response as I was away on leaves. Happy new year to you! Getting straight to your questions: 5. How about details on generator enclosure: Drip proof; TEFC; air cooled with air from non-hazardous area. If the latter what is shaft-bushing material? If your answer is...

@WTF? Can the power supply to B-N cards or the Vibration cards cause this issue? I mean if there is a power dip in DC circuit or some sort of intermittent supply failure? Have you witnessed anything of this sort due to power supply issues? Regards, MRasool

Hello, I am all for sharing knowledge as well, however few documents you can't share on public forums. Yes, I was rechecking the log and I noticed that both the vibration probes are going to alarm levels together and coming back together as well. However, there is a delay of 1 to 2 secs...

Hello Phil! I hope you are doing well. 1. Do the trips occur with some regularity with regard to activity, such as shift change? No, this actually happened for the first time since commissioning of this machine. Time was almost a shift change i.e. morning outgoing and evening incoming. 2. Do...

Hello, First off, thank you very much for the detailed reply. It was insightful. Now to answer your questions: 1- Make of Generator is BRUSH Electric.(Commissioned in 2008) 2- Packager is Nuovo Pignone. 3- The Seismic Sensors are Bentley Velomitor® Sensors. 4- We have a Mark-6. (Not a...

In my opinion, since the electrons in the DC circuit flow from Negative Terminal to Positive Terminal that is why the heating is more at the entry point i.e. -ive carbon brush, as opposed to the exit point i.e. +ive one. But that's just a thought. Ideas anyone?

That's a whole new debate. The design team looks after sizing. As a maintenance guy, I know the load is consistent at 2.4A and the 2A breaker is supplying that load since some years without any issue. However, we have installed a 4A breaker now. Regards, MRasool

Thanks Phil. But since the breaker has been ON since 5 years, as the PLC supplies a critical service(which we can't shutdown) there is no 'contacts parting' experienced on the MCB. Regards, Mutahir

Hey Phil! Good to hear from you. 1) What service does it provide in your facility? It is a frequency converter. We have unit which runs on 60Hz cycle and this unit converts 50 to 60Hz for that unit. 2) What are the motor's nameplate parameters? Nameplate Generator is(The pictures attached...
