Feature Explanation
Dip switch C - minimum speed off/minimum speed
15%. When dip switch C is in the ON position the
variable speed of the pump will have a range from
minimum speed = off to maximum speed = 100%.
When dip switch C is in the OFF position the variable
speed of the pump will have a range from minimum
speed = 15% to a maximum speed = 100%.
Dip switch D - speed control external/speed control
maximum % dial. When dip switch D is in the ON
position an external V(dc)/mA signal will cause the
pump speed to vary and the dial on the terminal box
will function in the -5% to +5% mode. When dip switch
D is in the OFF position turning the manual % dial will
vary the pump speed. The pump will not respond to an
external V(dc)/mA signal even if one is present. The
terminal box and the dial will function in the minimum
to 100% mode.
