HI - How do you set 2130 to use a strobe and does it have to be the Monarch Nova dvx style?
See what you can learn form the following links. Note that the last link concerns a cable adapter that you may need.
These all talk about tachs. I am interested in a strobe light application.

You'll need the CSI 555 strobe. As the package "A0555-30 Computerized strobe light package for 2130" you will find the product data sheet at http://www2.emersonprocess.com...130_ds_555strobe.pdf
Note that it is made by Monarch Instruments (see http://www.monarchinstrument.com/product.php?ID=35) so it might be worthwhile to compare prices.
JBALKO, CSI used to manufacture their own strobe, the 444. It is fairly large and somewhat heavy, but it is also built like a Sherman tank, and will do all sorts of things. They cost about $4000 at the time (20 yrs ago), but there is nothing else like them. I "know a guy" who has a bunch of these - some in mint condition - that could be purchased at a very reasonable price. If your're interested, drop me a line: precisn at suddenlink dot net
So no good answers here. So I called Emerson support and they don't even know how this 555 works. I had to send him and email so he could ask some one else.
I want this to work like an IRD 350. Walk up while running, take a reference run. Don't have to stop the machine and put tape on. 3 Runs on this machine took 2 Days. The 350 works great, but how long can you rely on that. If strobe works the same it would be great. I never used a strobe with CSI but with a datapac. Not even sure if the strobe and datapac could accomplish the same thing since the datapace makes you manually move the phase where the 350 says here it is, that is it. With the 350 you need on run and done. Phase lag and weight are already known.
So no good answers here.
Maybe there wasn't a very good question?
CSI never intended for it to work like a 350. I started my career with a 350 and balancing was pretty much a pain. As soon as I saw my first digital analyzer with a TTL tach I never looked back.
But what you want may be possible, or at least I think it would work with a 444 strobe. There is a strobe adapter that attaches to the DB25 port, and there was a cable that connected from the adapter to the 444. You brought a spectrum up in monitor mode, placed the cursor on a peak and "marked" it, and the strobe fired at that frequency. It was so you could visually find the different peaks in the spectrum. If the strobe flash is actually triggered by the accelerometer pulse, you'd have your "phase" reading. But if it just set the flash rate of the strobe, then you wouldn't. I think it just sets the flash rate, rather than triggering the strobe, so probably would not work.
BUT you could take the "output" of the 444 (and maybe the 555 if it has a TTL output -- it should have that) and run it into the tach "input" of the 2130. Then you go into monitor peak/phase and "freeze" the shaft with the strobe. You will have a phase reading on the meter. Using the phase adjust button on the 444, you slowly rotate the shaft until you have a visual reference (keyway or any distinctive mark or feature on the rotating shaft), and then you align that visual reference with your accelerometer, and freeze it there. Record the phase with the visual reference aligned with your accelerometer (I always have mine horizontal). That's your "reference" phase reading and you haven't shut your machine down. When you do shut the machine down, put a piece of tach tape on the shaft in line with the visual reference you used to take your phase reading. Hook your laser tach up to your meter, align it so it hits the shaft in line with the horizontal joint, and continue with your balance job.
If you don't have a laser tach, you need to get one. They are not expensive, $210 USD for a Monarch PLT-200 from Amazon. Trying to use the 2130 as an IRD 350 is almost criminal.
I am not entirely sure that you will understand this until you try it, or that you will even try it, or that you even want to understand it. Your comment ("So no good answers here") indicates you don't appreciate the considerable time that John spent finding those links, or my reply, so I'm guessing you won't do anything with the information I've given you.
That's the reason I don't use this board anymore. Too many lazy people asking questions they have not tried to research on their own, and then not appreciating the help they get. I really just posted to give you a sense of what is possible, IF you understand what your instrument is doing, but you have to experiment with it to know, and I doubt you will do that.
First Let me apologize for my use of the incorrect wording. That particular phrase did not come across correctly. I did not mean to offend or diminish the value of the board. I am still searching for the answer. I was hoping that someone used this and knew how to set it up. I have asked many questions here and received much valuable input in the past. As for lazy, far from it. Before I came here I read all of those posts and flyers. I called Monarch, CTC and I spent a couple hours experimenting with the collector, retrofitting wiring with a comparable strobe. I am anal about finding an answer that in the end may turn out to be meaningless. None the less the adventure and trill of trying to find the answer is the fun part. I end up learning a lot along the way. Again, I did not mean to offend and am sorry if it did so.
Monarch outlines some considerations here...http://www.monarchinstrument.c...0a%20Stroboscope.pdf
Keep in mind that prices escalates with RPM capability.
JBALCO, my apologies to you then. It's frustrating that so many here don't even Google a problem before they start asking for help.
I'm pretty sure your 2130 is not going to trigger your strobe like a 350. It's not meant to. There are much better ways of doing things now. It's the digital age.
JBALCO, any luck on this? I'm looking for the same functionality.
The OP stated: "HI - How do you set 2130 to use a strobe and does it have to be the Monarch Nova dvx style?"
There are two possible answers to your question based on how you intend to use the strobe with the analyzer.
1) Any strobe light (like Nova DVX) that provides a TTL pulse output signal can be connected to the tachometer input of the analyzer (BNC connector on the 2120 analyzer). The strobe light is first adjusted to show/freeze motion at 1X shaft speed, and then the analyzer will display shaft RPM. This would function the same way that any tachometer would (optical, magnetic, or Key Phasor)
2) Trigger the strobe flash rate from the analyzer. The CSI 2120 and probably 2130 analyzer can only do this when using the CSI 444 strobe light. The 2120 25-pin connector does not provide a TTL pulse signal output, so it cannot directly be used by the Monarch Nova TV X strobe light. I believe the CSI 444 strobe light uses RS 232 signal from the analyzer to control the frequency. So if you want to do this type of strobe operation, you would need to get a CSI 444 (not in production) or make an adapter and cable for RS 2322 controlling a variable frequency oscillator with pulse output. I do not have a 2130 analyzer, but I do have a 2120 analyzer and a CSI 444 strobe light, so I'm pretty sure this is a good answer my part.
I finally received the 555 manual, which is basically the user manual for the Novastrobe VBX. I also learned you must have the special CABLE. CSI would sell it but so does CTC (about 300.00). The cable plugs in to the collector and has 2 cables split from it. One for tach and one for accel. I'm not sure if the tach fires from the collector or somehow from the accel via the tach? Maybe that's why the tach cost 2600.00 from monarch (plus cable) and 4300.00 from Emerson. As you will see this excerpt, I am still not clear of the actual process. The entire section can be downloaded from monarch website.
As I understand it, the strobe should fire of the accelerometer. That signal coming in should send out a tach signal to the analyzer. I believe analyzer should collect accelerometer and tach data at the same time. Unsuccessful so far.
Thanx for the attachment. It tracks with what I think it should do. I beleive I have the wrong cable.
BTW -CTC said I or probably anyone, can purchase the cable and if needed send back within 30 day. So you could get it and test it.
I got 2 cables they sent out, both with CTC part numbers. I will call them tomorrow.
Talked to CTC today. They are looking into it.
Yep that's the cable. Lets see if you can get it to work.
Saga continues........hit CTC up again today, they said that I should call Monarch and they could help me out. This after Monarch told me they knew nothing about it. Might have to go rogue on this one and make my own solution.
Finally got the accelerometer signal to the 2130 analyzer. Had to use two jumpers to make the wiring like the original CSI cable where it plugs into the unit. I also got the Monarch VBX to work, kind of. It would lock on to the signal, but was off by about 100 RPM. More research needed on that.
