CEM+ dual Processor Configuration

Hi to all,

I've some issues regarding the setup of dual CEM+ processor on a ESR36 SENSOR + Rack.All the setup are ok on each processor, modification on A processor is copy on the B processor.But, the lower processor keep going to be the master and the upper one still the slave. If i remove the B processor the A become the master but when the two are online, the B is always the master.

I've try to wire a remote switch for a manual action without sucess no action at all. (Wiring with J12 connector with 12v on panic connector).

Thx for help.

Regards
