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.
