I am evaluating and testing speed switch alternatives for simple backup overspeed on some gas turbines. I am using this Dynalco SST 7000 series switch and can connect but get a firmware error so no configuration can be made. I reached out to the Barksdale/Dynalco help desk and initially had some basic suggestions but then stopped getting any answers to this firmware error, even when repeatedly following up. I prepared to return it to our supplier, and they pointed me to another distributor for technical support and I have not received any response as well.
Could be this is really a product that is working its way to the of a life cycle. I am not sure how long this has been released and maybe related to something with Barksdale that I assume acquired Dynalco. Part of produce evaluation is the support even if the product is good with poor support, it can be a bad no non-choice. I have tried many things. I even asked how to re-program or update the firmware and if I even have the latest as well as the latest tool and they did not even answer this basic question. Ironically, they asked me what version of firmware I was upgrading to. I replied and said I would be happy to if they provided a procedure, also with no response.
The trigger threshold has levels like low, medium, and high. I asked what voltage these correspond to as the help does not state it, and the answer was it would take too long to test to figure this out. Maybe this was sold-off and no one has design information/source any more ... I have seen it happen with products.
Anyone out there used this and has ... experience, comments, and/or tips please post if you could.
