Example Circuit for Classifier Outputs
Figure 6-7 shows an example circuit for using the classifier outputs.
These outputs are in the form of general purpose switch closures
available from the 15 pin “D” type connector located on the rear panel of
the instrument.
See
Section 2 – Specifications for pin assignments and response times
of the relays.
If the measured field is within the pre-defined classifier settings, both
relays are open and neither LED is illuminated. If the measured field is
above the defined limits, the classifier high relay is closed causing the
“High” LED to illuminate. If the measured field is below the defined limits,
the classifier low relay is closed causing the “Low” LED to illuminate.
