Just put power to my system for the first time. The Cerbo is showing only one Multiplus II and reporting error code #3 "Not all, or more than, the expected devices were found in the system." System schematic is below, along with Cerbo screen grabs. Victron brand network cables were used and terminators used at the second Multiplus, the Lynx shunt and the VT-3P75VT. This is a split phase 120/240v system. Suggestions would be highly appreciated.
you have to program the two multiplus II units so that they are setup as a split phase system. usingh a MK3 usb to VE.Bus converter ???
If they are programmed as split phase then the Comms connection from one of them is not good or the unit is still off physically.
Are both on, showing lights etc. the slave showing slave lights?
Can terminators are not used on ve bus. So probably the first thing to remove.
Thanks Alexandra. Both Multiplus physical switches are "on". Are all of the needed changes at the settings level, or do I need to make hardware adjustments? I only have 3 network terminators in place now: one on the second Multiplus, another the Lynx shunt, and the third on the VT-3P75VT. I'm a noob at this, diligently working through the manuals. Thanks for pointing me in the right direction.
Thanks Matthias. Follow-up question: Can I configure these two units for split phase configuration using settings in the Cerbo-GX, or will I need to use a Victron MK3 to USB dongle connected to a laptop to reprogram the devices? Appreciate your patience.
I am going to close this one off.
