OPERATING MODE 4 - Output adjusted
by frequency (Hz) input signal
In this mode, the pump’s motor speed is adjusted
automatically based on the frequency (Hz) of the input
signal. Any motor speed can be assigned to either the
minimum or maximum Hz input signals. However,
the programmed minimum Hz value must be less
than the programmed maximum Hz 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 Hz input signal values:
4 Set the pump for mode 4. Press the MODE button
until MODE 4 is shown on the LCD display. The %
