The
setting specifies the first (non-inverted) input to the FlexElement™. Zero is assumed as the input if
FLEXELEMENT 1 +IN
this setting is set to "Off". For proper operation of the element at least one input must be selected. Otherwise, the element
will not assert its output operands.
This
setting specifies the second (inverted) input to the FlexElement™. Zero is assumed as the input if
FLEXELEMENT 1 –IN
this setting is set to "Off". For proper operation of the element at least one input must be selected. Otherwise, the element
will not assert its output operands. This input should be used to invert the signal if needed for convenience, or to make the
element respond to a differential signal such as for a top-bottom oil temperature differential alarm. The element will not
operate if the two input signals are of different types, for example if one tries to use active power and phase angle to build
the effective operating signal.
The element responds directly to the differential signal if the
ment responds to the absolute value of the differential signal if this setting is set to "Absolute". Sample applications for the
"Absolute" setting include monitoring the angular difference between two phasors with a symmetrical limit angle in both
directions; monitoring power regardless of its direction, or monitoring a trend regardless of whether the signal increases of
decreases.
The element responds directly to its operating signal – as defined by the
settings – if the
