Two Wire Logic Starting
Re-configure the DSE 890 default configuration(s) by connecting SETUP::SEQ & REF::SEQUENCING
LOGIC::REMOTE REV OUT to SETUP::SEQ & REF::REFERENCE::REMOTE REVERSE.
This uses two inputs; RUN and REVERSE. The drive can operate in forward and reverse depending upon
which switch is closed. If both RUN and REVERSE are TRUE (24V) at the same time, both are ignored
and the drive will stop.
Note that the SETUP::SEQ & REF::SEQUENCING LOGIC::NOT STOP parameter is active (FALSE - not
wired to), meaning that the drive will only run while the RUN parameter is held TRUE.
