OPERATING MODE 3 - Output adjusted
by 0-10VDC input signal
In this mode, the pump’s motor speed is adjusted
automatically based on the value of the 0-10VDC
input signal. Any motor speed can be assigned to
either the minimum or maximum DC input signal
values. However, the programmed minimum VDC
value must be less than the programmed maximum
VDC value. The ALARM and SERVICE icons will
blink if the programming is in error. To assign the
minimum and maximum motor speed and the
minimum and maximum VDC input signal values:
4 Set the pump for mode 3. Press the MODE button
until MODE 3 is shown on the LCD display. The %
SPEED or VDC icon will light depending on the

indicate the current motor speed or the VDC input
value.

press the RUN/STANDBY and MODE buttons. A
blinking ARROW will point to the word PROGRAM
indicating the program mode is activated. A blinking
ARROW will point to the word MINIMUM indicating

SPEED icon will blink indicating the percentage of
speed is ready to be programmed.

signal value. Press the FIELD button to select the
digit to program. The digit will blink when selected.
