Figure 4-16. Changing the Priority of a Slave Unit
A priority change at units with the network addresses of #2 and #3 switches the
network priority between these two units. Since neither unit is operating (only the
master is on load) the priority change takes place, and is recognized by the
master. The change is seen in the next on /next off display at the master
sequencing status screen. See Figure 4-16.
