Hi All! I've been sent some plots from an ADRE system, of an X and Y probe looking at a shaft. One of the plots has "A/D UNDER RANGE (FLAGGED PLOT)" written within the plot area, and the other probe has "A/D OVER RANGE (FLAGGED PLOT)". What do these two statements refer to, and what do they mean? I can understand that the "OVER RANGE" is probably because the actual signal is greater than the signal range in the analysers settings, but what is the "UNDER RANGE"? Also, will the Over range plot...
Dear Users We are long term users of the ADRE 408 data acquisition system, monitoring vibration information on our large rotating machines. We typically monitor vibration levels from Bently Nevada non-contact shaft proximity probes, and numerous seismic transducers during our machine testing. We have a new requirement to monitor bearing housing vibration, and perform a kurtosis analysis on the data. For this we need a sampling rate of 25,000 samples/second. I know the fastest sampling rate...
Is there anybody on board who had experienced in the past upgrading their ADRE 208 to ADRE 208-P? Bently Nevada in the early 2000s had this Kit available to Customers in order to make use of newer computer at that time. I am interested in knowing what are the contents of this Kit and instruction procedures (if any) for doing the conversion. Former BN Employees may have some information save on their file. Thanks, Boni
Hi All! I have just got ADRE Sxp software installed today, and I have some data from a customer, which was recorded on their ADRE. Can anyone tell me how I import the files so that I can view and analyse them? Thanks Nick
Wow, ancient history! I was a BN employee and converted many a 208 to 208P. I can tell you that this is not a conversion that would involve obtaining some electronic components and making a few changes. It involved the replacement of several of the main boards in the unit. I'm working from memory but perhaps three boards were involved, totally different than the boards in the 208. The front panel was also changed although I don't remember if this was done solely so the unit carried the 208P...
Thanks John! I know you will reply. You are correct both ADREs have completely different on 2 boards (Top board and DSP second from top) but identical for 3 other boards. Enclosed is the picture of ADRE 208-P showing all the five boards installed. I got the 2 boards (Top card and DSP card) from ebay few days ago and for sure were taken from ADRE 208-P CE. I have both ADREs. The other ADRE 208 is not a CE where I have planned to upgrade once I received those cards. I noticed the case of ADRE...
All I can remember is changing the cards and the front panel (for identification), but I can't say positively it was two or three cards that got swapped. But beyond that, there wasn't anything that needed to be done. I assume you have the cables needed for the 208P? You are probably correct that the two aluminum strips were to improve contact with the top cover and that might have been part of CE. Early on, even in non "P" days there was also a nylon spacer added at the power plug on the...
Thanks again John! I will take note of the nylon spacer and will find a way to look for aluminum equivalent. I am positive that you only swapped 2 cards because the 3 others cards are exactly identical PWA even the revision letter. I am assuming that after swapping the 2 cards it will work same as P version and that I could interconnect the two. I have computer and interconnection cables for the P version. Thank you, Boni
As best I recall, the nylon spacer is what you want, not aluminum. The reason I think that is I encountered the issue and it literally resulted in a small burn spot from the arc. I was assured there wasn't any way an arc could occur so I sent my unit in and asked "how did the burn spot get there." The unit came back with the nylon ring.

Working. 2 Boards/Cards required for the upgrade: 1. PWA 132953-01 2. DSP PWA 133154-01 John, the Adre I have has a power supply jack with plastic/teflon insulation so BN already addressed the risk of sparking. Thanks for the help. Boni
The 208/208P can function perfectly without a battery. Simply plug the 208 into a UPS or back up power source. Keep in mind that the original battery was intended to provide several hours of use, perhaps 4 as best I recall, but the average UPS like you might buy for a computer, will likely only provide minutes of use. There was also a blank front panel available that covered the battery compartment rather than leave an opening with exposed electronics. It is no longer available so I I...
Depending on certain condition for example, machine you are diagnosing is use for isochronous operation or black start where ADRE battery is essential otherwise AC is always available. There is also a situation where battery is needed during an unexpected brief power interruption say during plant switching of startup transformer, however, this can be addressed by UPS. Since the battery is no longer available you can virtually forget it and have UPS with you. There may be sizeable UPS that...
Two solutions: 1. Buy an older serviceable laptop that supports the 208P. Some desktops that had EPP compatible parallel ports may work. 2. Consider the purchase of a 408. Consider in your decision that the 208 is technology from the late 1980's and as good as it was (or still is) it basically isn't repairable.
We have Panasonic Toughbook CF-28 and CF-29 with EPP ports and still running Windows XP. The 208 may be old but it still runs and provides good data. Would like to upgrade to a 408 but it's hard to justify.
Hey Pak, Keep us posted. There are still a lot of functioning 208's out there. It would be nice to also have it work with something other than XP, like windows 8, or since GE no longer supports the 208, have some group come out with a new program that does.
DAIU 208 is a very practical piece of art. It is heavy duty and designed for most of the common turbomachinery cases. My advice if you like to keep using it is to have a backup for all possible parts. I had failures in the charger, the battery and the cable. Before it was phased out by Bently, we purchased spares and we have been using it till nowadays. But if this instrument is really your money maker, I would suggest to have an alternative to avoid the risk of not being able to deliver...
It would be great to find an appropriate USB adapter, but this is unlikely! Google: usb to parallel port epp I need a USB Parallel port on a laptop, a real parallel port, not USB printer port. Pasted from < http://arstechnica.com/civis/v...p?f=11&t=1281419 > an interesting discussion with some salty language! The conclusion is that the USB port cannot support interrupts that are needed to communicate with instruments. Parallel printer communication is apparently possible. Walt
Walt, If you already have the 25 pin cable you need an XP laptop and a special card that replaces the CD drive with a parallel port connections. Not all brands/models laptops will convert. What cable and laptop do you have? Feel free to call me at 863.370.9039
I have a Lenovo X61 tablet computer with attachable docking base that has a CD drive. It has Windows XP, and it is currently on the shelf. Do you know of a parallel port adapter compatible with the setup? Getting back to the original question, I guess you don't have a solution for a USB to parallel adapter that would be capable of working with an instrument instead of a printer. A few years ago I was looking hard for one, but concluded nothing was available. Walt
Walt, The only to connections I have seen are the PCMCIA and the parallel connections. I have looked at the cables offered by Bently and never seen a USB. If the X61 is like the T61 then buy adapter # 40Y8122. I don't see any on line now but I expect you can find it somewhere. If the X61 is not like the T61 then I have no idea.
Trust me on this, there isn't another solution except a connection using a PCMCIA adapter, a 25 pin parallel cable, and a laptop (Win XP) that has an EPP compatible parallel port. I have configured many computers and some just plain won't work, even after hours of work, and I (at least at one time) knew what I was doing. We at BN were using Dell D620's or D630's and they were relatively easy to set up. Having said all that, you never know until you try.
A manual does not exist. The product was designed to be supported through the "Help" file which is very extensive. You don't have to do much searching; if you are at a screen where you need help hit the help button and you will get a help topic unique to that specific screen.
No, the quick start manual isn't the basis of the case. It is hands on, ranging from setting up a database to understanding signal processing. You configure based on scenarios and run rotor kits to collect data, hopefully understanding the ramifications of your decisions and without risk to machines or personnel. The advantage is you will actually do things if you attend the course. You are less likely to seek out an answer in the help file.
If this is the 208 system then it saves the data up to 50% over the Full Scale Range (10 mil FS goes to 15 mils). Yes the samples are labeled "Flagged Data" and can be included or excluded from the plots. If this is the 408 then I am not sure. Talmadge
With respect to the 208P/Adre for Windows software, I do not think the "overhead" for the A/D converter is as high as 50%. That is a spec we (I worked for BN) generally didn't publish but the value of 5% or 20% overhead capability is common in industrial design. I personally would not use anything above the 20% level for either the 208P or 408DSPi.
