Hello I am pulling my hair out, hopefully you guys can help me out. I purchased a 12 Channel relay(L5512RVF) I am trying to integrate it into my existing network but every time I connect it to the cbus network the whole network goes down. The cbus indicator goes out as soon as plug in the cbus network even when this relay is only connected to 1 of the existing dimmer unit I have used the Cbus calculator to see if I require a power supply but as I expected I don’t Project Network Network 1 Description Cat No Qty Passive Infrared Motion Detector, Indoor, Corner Mount 5751L 1 Passive Infrared Motion Detector, Indoor, Flush Mount 5753L 8 Multi Sensor 5753PEIRL 4 4 Gang Saturn Key Input Unit 5084NL 2 5 Gang DLT Input Unit (Saturn) 5085DL 3 DIN Rail 12 Channel Voltage Free Relay 10A per Channel L5512RVFP 1 DIN Rail 8 Channel Voltage Free Relay 10A per Channel 5508RVF 2 Pascal Automation Controller 5500PACA 1 DIN Rail 4 Channel Dimmer, 2A per Channel LE5504TD2A 1 Total 23 Units consume 392 mA Power balance OK Max supply 600 mA Safe if short circuit AC impedance 0.77 kOhm Enable one burden only Fyi: I also have a SHAC unit which is not available in the calculator I have but the relay into super learning mode and disabled the clock and burden as the existing units will supply the necessary signalling. Can you give me any advice in resolving this issue?
