Note 1: The transition from any state to the Idle state due to i_bActivate=OFF is not shown. However these transitions have the highest priority (0).
Note 2: Within muting substates, transitions due to Error Muting sequence (priority 1), Error Timer (priority 2), Safety demand AOPD (priority 3) or Error Muting
lamp (priority 4) have higher priority than transitions to Muting substates (priority 5).
Note 3: Muting condition 1-3/11-13 and Wrong muting sequences are shown in the following.
• Muting conditions 1-3 ( Page 83 Muting conditions (forward direction))
• Muting conditions 11-13 ( Page 83 Muting conditions (backward direction))
• Wrong muting sequences ( Page 83 Wrong muting sequences)
Note 4: Time parameter error (condition of transition from 8001H to C005H) is detected in the following case.
1) i_dMaxMutingTime has been set to a value less than 0ms or greater than 10min. (0 > i_dMaxMutingTime OR i_dMaxMutingTime > 60000)
