Establishing Power to the Electronics:
Once the two wires of the shielded cable are properly connected to the
terminals inside the junction box as described above, connect the other
end of the two wires to a suitable 12-36V DC power supply with
negative ground such as a PLC, DCS, etc.
The digital display responds instantaneously. When power is applied,
the transmitter performs several diagnostic system status checks termed
