Model 1700 and 2700 Transmitters
Wiring the Transmitter to the Sensor
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 cable 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 cable 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.
CAUTION
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.
