I have a Flexboss21 and dry contacts are metnioned in the manual. However I can't find any referencon how to program them. Is it possible to use the dry contact on the flexboss as a generator start signal
Yes, — but only if the device actually supports that function. If the manual mentions dry contacts but doesn’t explain how to program them, it’s possible the feature is there but not enabled by default. I’d suggest checking any advanced settings.
My understand (and I could be wrong) is that you need a grid boss paired with the Flexboss to get gen functionality.
Sometimes the easiest solution is the best solution.
Sometimes not.
