CT (current transformer) Input Configuration Page
The CT input accepts a signal from a CT monitoring heater current. The CT develops an output signal propor-
tional to the current flowing through the wire passing through the center hole of the CT. You can assign one or
more alarm outputs to any CT input. The alarm can be configured to trip if the heater current gets too low or too
high. The CT input cannot be used with a process output. See Features chapter.
Note: You must click Submit to send the new values to the Series PD.
