NOTE
Internal/Closed loop: The FC 103 will control the
application directly using the internal PID control within
the frequency converter and needs an input from an
external input such as a temperature or other sensor which
is wired directly into the frequency converter and controls
from the sensor signal.
External/Open loop: The FC 103 takes its control signal
from another controller (such as a pack controller) which
gives the frequency converter e.g. 0-10 V, 4-20 mA or FC
103 Lon. The frequency converter will change its speed
depending upon this reference signal.
