Hi all, On a Cbus job I had to investigate a fault that the master off wasnt working on a 5 story building in Melbourne. There is a Minder that gives the MASTER OFF command. I tried scanning the network with toolkit and noticed I couldnt scan the A side of 2 Network Bridges. On inspection I found the A side LED dead. I removed the NBs and tried them on small local test network but they were dead. I thought all a bit strange and checked my A side voltage which was 34v all good and I could scan all other NBs and networks. I ordered 2 new ones and when I went to insall them I noticed another had died in the week that passed. Checked voltages again and all seemed OK. This install has been running for about 4 years. Has anyone got a possible explanation for this Cheers
