6.3 OPERATING MODE 1 - Output adjusted

manually -

In this mode, the pump’s motor speed is adjusted
manually using the front panel touch pad. The motor
speed can be adjusted from 5-100%. To adjust the
speed:

4 Set the pump for mode 1. Press the MODE button

until MODE 1 is shown on the LCD display. The
%SPEED icon will light. The large 3-DIGIT LCD
will indicate the currently programmed percentage of
speed.

4 Enter the programming mode. At the same time,

press the RUN/STANDBY button and the MODE
button. A blinking ARROW will point to the word
PROGRAM indicating the program mode has been
activated.

4 Press the FIELD button to select the digit to program.

The digit will blink when selected.

4 Press the DIGIT button to change the selected digit.

4 Repeat until all digits are programmed.

4 To exit the programming mode, press the

RUN/STANDBY button and the MODE button at the

6.2 How to adjust the output- manual stroke adjustment

The

Pump flow rate can be adjusted within a range of 5% -100% of maximum
output (20:1 turndown ration) by means of a mechanical, cam type
mechanism. The mechanism adjusts the pump’s stroke length to an infinite
number of settings within the flow range.

Note: The pump’s output will reduce due to increased system pressure,
increased suction lift, and increased fluid viscosity. The pump must be over-
sized to allow for these factors. Sizing the pump to allow adjustment within
the midrange is preferred to maintain accuracy. Consult the factory for
individual pump model output curve data.

To adjust the pump’s output:
1. With the pump running, loosen the lock screw.
2. Turn the adjustment knob to the desired setting.
3. Re-tighten the lock screw.
