power is removed and restored or the user changes the transducer block target mode to Manual or Auto. In any
case, the target mode will remain Out of Service, if the condition that caused the shutdown remains or until the
shutdown trigger is disabled.

D Drive Current Alert Time (DRIVE_CURRENT_TIME [83.5]) is the maximum time that the Drive Current Alert Point can
be exceeded before the Drive Current Alert is active.
