When the analog output is set to provide pressure signal, the voltage level
is proportional to pressure level and it is generated by control unit
elaborating the independent input by the active gauge.
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" (i.e. the output is normally OFF and
changes to ON when activated), or "low level active" (i.e. the output is
normally ON and changes to 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 rebound.
