3. Install 5 connector shielded cable (factory or customer supplied) between the sensing element and the control
circuit. Refer to Figure 2-1 or 2-2 for connection information.
4. Ensure the specified operating power is supplied to the control circuit. Refer to Figure 2-1 or 2-1 for connection
information. FCI recommends that a switch and a line fuse be installed near the control circuit rack in order to
interrupt operating power during installation, maintenance, and troubleshooting.
5. When connecting the relay wiring, do so with complete understanding of what the process requires of the
instrument. The instrument has dual switch points with a SPDT contact configuration for each switch point. For
the relay logic, refer to Figure 2-1 or 2-2 and Tables 3-4 through 3-6 (Chapter 3 - Operation). Relay contacts are
shown with the relays de-energized. Wire in accordance with the system requirements.
6. Plug the control circuit into its rack position.
7. Verify the proper installation of the instrument by checking the following items.
• Check that the assemblies are secure and the wiring is correct.
• Check that the serial numbers on the sensing element match the serial numbers on the control circuit.
The sensing elements and control circuit are tested and adjusted as a matched set at the factory.
Mismatching of the sensing element and control circuit will cause poor performance.
