NOTICE!
Internal/Closed-loop: The FC 103 will control the
application directly using the internal PID control within
the adjustable frequency drive and needs an input from
an external input such as a temperature or other sensor
which is wired directly into the adjustable frequency
drive 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 adjustable frequency drive, e.g., 0–10 V, 4–20
mA or FC 103 Lon. The adjustable frequency drive will
change its speed depending upon this reference signal.
