Wiring For Remote Core Processor With Remote Transmitter Installations - Emerson Micro Motion 2700 Installation Manual

Wiring the Transmitter to the Sensor continued
3. Ground the cable.
If using jacketed cable:
a. Ground the shield drain wires (the black wire) only on the core processor end, by
connecting it to the ground screw inside the lower conduit ring. Never ground to the core
processor's mounting screw. Never ground the shield drain wires at the sensor junction
box.
If using shielded or armored cable:
a. Ground the shield drain wires (the black wire) only on the core processor end, by
connecting it to the ground screw inside the lower conduit ring. Never ground to the core
processor's mounting screw. Never ground the shield drain wires at the sensor junction
box.
b. Ground the cable braid on both ends, by terminating it inside the cable glands.
4. Ensure integrity of gaskets, grease all O-rings, then close the junction box housing and core
processor end-cap, and tighten all screws.

Wiring for remote core processor with remote transmitter installations

This task includes two subtasks:
• Subtask 1: Wiring the remote core processor to the transmitter (4-wire cable)
• Subtask 2: Wiring the sensor to the remote core processor (9-wire cable)

Damaging the wires that connect the transmitter to
the sensor can cause measurement error or
flowmeter failure.
To reduce the risk of measurement error or flowmeter
failure, when closing the housings on the sensor and core
processor, make sure that the wires are not caught or
pinched.
