FAULT: this open collector output signal is ON when a system fault condition is
detected.
PROGRAMMABLE SET POINT: this open collector output signal is enabled when the
reference quantity chosen (frequency, power or time or pressure 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 activated), 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"
