Note
Once a leak has been detected
by the system, the controller
will shut off the pump. This
digital port is used to
deactivate the leak alarm so
that normal pump operation
can continue.
Send leak detect inputs into
this digital port
If operating a pump with end
stroke detection instead of a
shuttle operated pump the left
and right proximity sensor
inputs need to be connected to
these digital ports. The left
proximity switch input will be
used to count cycles.
For those using a shuttle pump
and want the controller to
preform cycle counting, then a
pressure switch can be
connected to the pump. See
pump's owner's manual for
details.
These digital outputs have been
designated to notify the user
which mode the controller is
operating in. If none are on,
then the controller has been
turned off.
