PROGRAMMABLE ANALOG SIGNAL
: this out-
put signal is a voltage (from 0 to 10 Vdc) propor-
tional to a reference quantity (frequency or power
or Temperature or Pressure) set by the user. The
default setting is the frequency (see the following
example diagram).

FAULT
: this open collector output signal is ON
when a system fault condition is detected.
PROGRAMMABLE SET POINT
: this open collec-
tor output signal is enabled when the reference
quantity chosen (frequency, power or time or pres-
sure or normal) is higher than the set threshold.
The signal can be "high level active" (that is the
output is normally OFF and becomes ON when ac-
tivated), or "low level active" (that is the output is
normally ON and becomes OFF when activated).
Moreover, if the reference quantity is the frequency
or the power or pressure drawn, it is possible to
set the hysteresis (in % of the threshold value) to
avoid bouncing.
For example:
−
reference quantity: frequency
−
threshold: 867 Hz
−
hysteresis:
2%
−
activation type: "high level"
