0 - 10 VDC Input (Volt DC)
Used to remotely control the pump with an incoming 0-10 VDC signal.
Default settings:
0 VDC = 0% motor speed
10 VDC = 100% motor speed
Press MODE button until
0 - 10 VDC Input i
s displayed in the top line of the
display.
To configure the pump, navigate to
0 - 10 VDC Input
menu by using the short-
cut method described at the beginning of the section, or by pressing MENU
button, then selecting Input Setup, Input Modes, and then
0 - 10 VDC Input
.
Four points on the slope must be defined; 1) a low VDC value, 2) an output rate
at the low VDC value, 3) a high VDC value, and 4) an output rate at the high
VDC value.
To input VDC values, press the RIGHT ARROW to select the digit to change,
press UP or DOWN arrow to scroll through 0 - 9 on selected digit. Press enter to
save changes and move to the next input screen.
To input flow rate values, press the RIGHT ARROW to select the user defined
flow rate unit of measure, motor RPM, or %Speed values. Press UP or DOWN
arrow to increase or decrease the value. Press and hold the arrow to increase or
decrease progressively faster. Press enter to save changes and move to the
next input screen.
Continue this process until all four screens have been configured.
If you used the short-cut to enter 0 - 10 VDC Input setup, press and hold Mode button until Run Mode screen is
displayed.
If you used the Menu button to navigate to 0 - 10 VDC Input setup, you must navigate back out of menu structure.
To do this you must select <-Esc at bottom of every screen menu until you see Run Mode screen displayed.

Frequency Input (Hz)
Used to remotely control the pump with an incoming high speed frequency
signal. Typically used with flow meters or other external devices.
Default settings:
0 Frequency (Hz) = 0% motor speed
1000 Frequency (Hz) = 100% motor speed
Press MODE button until
Frequency Input
is displayed in the top line of the
display.
To configure the pump, navigate to

.
Four points on the slope must be defined; 1) a low Hz value, 2) an output rate at
the low Hz value, 3) a high Hz value, and 4) an output rate at the high Hz value.
To input Hz values, press the RIGHT ARROW to select the digit to change,
press UP or DOWN arrow to scroll through 0 - 9 on selected digit. Press enter to
save changes and move to the next input screen.
To input flow rate values, press the RIGHT ARROW to select the user defined
