Hybrid Analog Output and High Input Signal
Selection Control
Figure 14 shows a System 450 control system that
uses the hybrid analog output to control motor speed
on an Electronically Commutated (EC) condenser fan
motor and the High Input Signal Selection feature to
provide the pressure input signal according to the
higher of the two pressure values sensed at the two
transducers.
