Only company I know of that can servicer MWM controls outside of the existing MWM network is PowerUp in Austria, https://www.powerup.at/solutions/workshop/ There was another company in the Netherlands a few years back that could do MWM controls, but haven't heard about them since CAT bought MWM.

Likely someone who does commercial lighting systems. Legrand has several versions of lighting control panels, just finding a contractor with experience on your particular system may be a little hard depending on where you are located. Your best bet may be to go to Legrand's website and see if...

Are you trying to connect to the DECS AVR while the unit is OFF? The DECS has no auxiliary power input, if you are trying to connect to the DECS with no power input on terminals 3,4 and 5 the AVR will not respond. If you want to program a DECS AVR offline, you can connect a power cord two any...

Does your computer have a native RS232 port? Or are you using an adaptor like a USB to RS232? I have found the older Basler software can be picky about Comm Port numbers, older AVR's and their software would only recognize com ports 1-9. Go into your Device Manager and verify what port you're...

I have done quite a few retrofits last several years where having ability to read metering off the protective relay is desired. To Cranky's comment, yes, most folks not familiar with the relays don't want to touch them, a pretty simple solution since just about all newer protective relays have...

I have used the Eaton breakers from here quite a bit over the last few years, and aux contacts and shunts are available, as well as LOTO devices...

Cranky, I was going by his drawing, shows two sets of PT's. This is an exercise I have had to go thru many times over the last several years, made me REALLY appreciate modern multifunction protective relays. Had multiple customers running gensets, mostly landfill or digester gas plants, that...

What kind of protective relay do you have installed? If your fault recording is properly setup then you should have an oscillograph or data from the fault. Using that info will help you identify the actual reason for the trip and point you in a direction to correct the issue. I have worked...

Can you run an SI (Spark Ignited) engine running on DG, NG or Propane fuel? A small non-lean burn SI will have an exhaust O2 between 1 and 3%, if you have a catalytic convertor on it and tune the engine properly the exhaust O2 will be around .5%. If you provided more details about your site...

I was in SoCal dealing with these issues since 1981, between CARB and the local air boards it got tougher as time went on. BACT determinations didn't always seem to have technical backing behind them, someone would make a claim and that would get pushed down to the users, and a lot of times the...

Tug, API gravity is used by engine manufacturers for a couple reasons, mainly it's what EMA (Engine Manufacturers Association) agreed upon early on, and when doing corrections for fuel consumption and power output, API gravity directly follows temperature variation, so as temp goes up, so does...

Tug, Ran into to this issue several years ago in SoCal, some crew and supply boats servicing rigs in off Ventura complained of power and fuel consumption issues on both varying degrees of bio-diesel and HVO fuels after a change in fuel was mandated by the local air board. We did a program with...

It depends if you are using features on the units with the DECS 250N that the DECS 200 does not have. The attached is a publication by Basler to upgrade a DECS 200 to a DECS 250, and describes the features, mounting and wiring differences. The main differences between the two are, DECS 250 has...

Tug, Been where you're at more than a few times. Are you doing a single vessel or multiple? If multiple vessels, are they the same design, displacement and doing the same type work? For a one off, a micro PLC designed for machine tools is probably the best solution, especially for the first...

If you are replacing a failed VR3 AVR (9Y8400), then you have a pretty old SR4 generator. 3 out of 4 VR3's I replaced in the field over the years died as a result of a problem external to the AVR (and I replaced a lot). If you're failing the input fuses either the input voltage is too low or...

Muthu is here on the forum, surprised he hasn't chimed in yet. I believe he would have the expertise and ability to help you develop a test stand based on your needs. His website, https://www.edison.co.in/ Good luck in your venture, MikeL.

Since it seems your customer is an electrical equipment manufacturer in India (I was curious), your best possible resource in this forum is likely Muthu from Edison Company India. To meet the spec you provided you're likely going to have to build a custom test stand.

Ok, now that I read your attachment (be aware that this is done with caution with all the crap on the internet these days). Your attachment is a specification for testing a rotating rectifier assembly ONLY, not installed on a final machine. Funny, it VERY similar to an acceptance test document...

The only company I know of making a functional online diode monitoring system for salient pole generators is KATO. https://prod-cd-nidec82.layeroneclients.com/generators/kato-engineering/-/media/katoengineering/documents/literature/krm2000-wireless-system-9-2017.ashx?la=en They tend to be very...

Tug, A BTW, make sure they have pressure measuring taps at the right locations to evaluate the actual pressures under load, especially since you have an SCR. I attached the most recent CAT A&I for Exhaust Systems, thought you might already have it but in case you don't it's a good reference...
