OPERATING MODE 2 - Output adjusted
by 4-20 mA input signal
In this mode, the pump’s motor speed is adjusted
automatically based on the value of the 4-20 mA input
signal. Any motor speed can be assigned to either the
minimum or maximum milliamp input values.
However, the programmed minimum mA value
must be less than the programmed maximum mA
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 mA input signal values:
4 Set the pump for mode 2. Press the MODE button
until MODE 2 is shown on the LCD display. The
%SPEED or mA icon will light depending on the
current display setting. The large 3-DIGIT LCD will
indicate the current motor speed or the current mA
input value.
4 Enter the programming mode. At the same time,
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
the minimum value is ready to be programmed. The %
SPEED icon will blink indicating the percentage of
speed is ready to be programmed.
4 Enter the motor speed at the minimum mA input
signal value. 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 Press the mode button. The % SPEED icon will stop
blinking and the mA icon will blink indicating the
minimum mA value is ready to be programmed. The
currently programmed minimum value is shown on
the 3-DIGIT LCD.
4 Enter the minimum mA input signal value. Note: this
value must be less than the maximum mA input signal
value. 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.
