Figure 275:
Operation principle of REALCOMP
When EnaAbs
is set as absolute comparison and
SetValue
is set less
than 0.2% of the set unit then INLOW output will never pickups.
During the above mentioned condition, due to marginal value for
avoiding oscillations of function outputs, the INLOW output will
never set.
