Page 15 801P5 Smart Switch
TM
STANDARD VS. WINDOW MODE
The terms “Standard” and “Window” describe two methods for
setting up the Smart-Switch
TM
to monitor pressure.
Standard Mode
In Standard Mode, illustrated in Figure 8, the
SP1i
(or
SP2i
) set
point actuates when the pressure being monitored goes above the
set value. At this point, the Smart-Switch
TM
might turn off
whatever electrical power is being applied to a pump, for
example, which is increasing or maintaining the pressure. The
switch de-actuates, or resets, when the pressure drops below the
preset decreasing set point (
SP1d
or
SP2d
). At this time, the
electrical power to the pump would be turned back on.
