Upon turning Duty Rotaon ON from OFF, Main unit will be always be turned on first (becomes running
unit). Sub unit will become the backup unit. Running and backup unit will rotate based on a rotaon
interval set from remote controller. Aer rotaon interval ends, Main unit will be turned off (becomes
backup unit) and Sub unit will be turned on (becomes running unit) for the next rotaon cycle. Role of
running and backup unit will rotate between Main and Sub unit for each new rotaon cycle.

1.3 Unit response to error and breakdown (Controlled by CN-CNT Signal)

communicaon with error unit
