Note
: The settings shown above for Run, Clockwise rotation and Auto are those in
force on initial start-up for the functions available on Output 1, Output 2 and Output
3 respectively. For example, a high signal on Output 2 indicates clockwise rotation.
These can be changed later according to user requirements.
Note
: High is equivalent to the common and normally open contacts of the relay on
the module board being closed.
