SPEED SETTING: PWM input signal to set the pump speed. The
PWM signal characteristics must be the following:
Figure 16
If any signal isn't applied (no connection) the pump speed is set to
"High Speed" (1010 Hz max and settable by window "120").
If a continuous signal is applied (pin 5 fixed at +24 V and pin 6 fixed
to ground) the pump speed is set to "Low Speed". The Low Speed
frequency is settable by window "117" (see para. "RS 232/RS 485
Communication Description").
PROGRAMMABLE ANALOG SIGNAL: this output signal is a voltage
(from 0 to 10 Vdc) linearly proportional to a reference quantity
(frequency or power) set by the user (0 V = 0 W or 0 Hz; 10 V = 150 W
or 1010 Hz). The default setting is the frequency.
FAULT: this open collector output signal is ON when a system fault
condition is detected.

frequency: 100 Hz +/-20 %
ampitude: 24 V max
duty cycle range: from 25 % to 75 %
corresponding to a pump speed from 750 Hz to 1010 Hz (see the
