17 Technical Information
J1 - In-Out
RELAY CONTACT: This relay output signal is enabled when the
reference quantity chosen (frequency, current, time) is higher than
the set threshold. The signal can be "normally open" (it will close the
circuit when activated) or "normally close".
The factory default setting are:
These setting can be changed by serial interfaces (see "windows
meaning" table: windows 101 to 105). The same settings are used by
the "programmable set point".
SPEED SETTING: PWM input signal to set the pump speed. The
PWM signal characteristics must be the following:
The duty cycle percentage is referred to the low level portion of the PWM signal
NOTE
PROGRAMMABLE ANALOG SIGNAL: this output signal is a voltage
(from 0 to 10 Vdc) proportional to a reference quantity (frequency or
power) set by the user. The default setting is the frequency (see the
following example diagram).

Hysteresis: 2%
Activation type: normally open
Delay time: 0 sec.
frequency: 100 Hz +/-20%
ampitude: 24 V max
duty cycle range: from 25% to 75%
corresponding to an output frequency from 272 Hz to 646 Hz
linearly.
