Note 1. Transitions to the Idle state from any other state are not shown for when Activate changes to FALSE.
However, the transition to the Idle state has the highest priority (0).
2. A state transition to Error Muting sequence (priority 1), Error Timer (priority 2), Safety Demand AOPD
(priority 3), or Error Muting lamp (priority 4) in the muting substates has higher priority than a state tran-
sition to muting substates with priority 5.
