The Transition Complete input was found to be opened with the
compressor motor running after a successful completion of
transition. This is active only for Y-Delta, Auto-Transformer,
Primary Reactor, and X-Line Starters. To prevent this diagnostic
from occurring as the result of a power loss to the contactors, the
minimum time to trip must be greater than the trip time for the
power loss diagnostic.
