4.1 Connect a second CBU controller
It’s possible to connect an additional CBU controller (MASTER) to the main generator CBU controller
(SLAVE), in order to drive and monitor the generator from 2 different positions.
CBU MASTER sends and receives data from CBU SLAVE controller that directly control the generator.
CBU MASTER can not control the generator without CBU SLAVE.
The two controllers works via 485 mode bus protocol, keeping the same features of control and
command.
At first power on, CBU MASTER self-configures to the twin Slave.
When turn on CBU MASTER, CBU SLAVE also turns on, but not viceversa. You can still turn on at all
times CBU MASTER.
Disconnect battery before doing wiring connections.
Have the access to rear side of CBU SLAVE, locate the connection points.
Connect wirings according to the reference diagram (CBU SLAVE diagram does not show all the cables
connected to it, refer to the diagram of your machine if necessary).
