Thank you. What you’ve done for us already is above and beyond. We all really appreciate it over here.
What we’re trying to do is drive a few bypass dampers in a VAV system with no VFD on the supply fan. The rooftop units are older. We’re doing an upgrade on the client’s old control system.
V 126 works exactly as we’d like as far as control goes, but as stated, they seem to drop off the bacnet network at least once every 10-20 minutes.
It may even be an issue on our end? Does anyone have any ideas on how to check that?
So far, we have:
Got a v 125 controller on the bacnet. jussleman found out we couldn’t command the damper directly over bacnet.
We reached out to you guys, you provided us with new firmware, again, thank you. That’s incredible, and isn’t unnoticed.
After installing the updated controller it was noticed that it’d restart every so often. It also seemed to slow down our network. We reversed the polarity of the 24vac, we checked input voltage, we completely disconnected the damper actuator, we swapped out the PS-1 for another updated PS-1, we swapped out the updated PS-1 for a v125 PS-1. Same thing.
I had a couple of them on my desk today for a few hours. One on the rs485 network, and the other not. Neither one was connected to anything else. I don’t think the one that was off of the 485 network had any issues at all. I didn’t see it reboot. The one on the 485 network did.
Baud rates checked. Mac add’s checked. The rest of the network seems stable. These tests are going on in the middle of our daisy chain. Devices after stay online, but overall stability is compromised.
Again, thank you guys/gals. What you’ve already done for us is amazing. We look forward to using your products again on future projects.
