CIRCON

[richper]

Any one out there to field some questions about a Circon system ? We have a job with 185 Vav. terminals driven by circon actuators and a multitude of equipment linked up to a Circon B.M.S. We are having many problems and I sure can use some advice. So if there is someone out there to talk to please let me know. Thanks in advance, Rich.

The controlers on the VaV's seem to lock up .The led's are flashing green but you get no response from the space slide control or remote work station.A bus scan at that time reports all online. We simply reset power to the Vav's control trans and the damper starts modulating and the T. stat takes control.Im interfacing to the netwok with VISUAL INTERGRATOR and also SYSTEMS INTEGRATOR. More questions to follow .Thanks for now!!

Check the health of the channel with a PA (protocol analyzer). Too often, excessive network traffic can cause tool to device communication issues. Troubleshooting without a PA is like diagnosing an electrical problem without a multi-meter. You need to see what's happening on the channel as far as bandwidth consumption and error rates.
BTW, Circon has some outstanding support guys!
