IMPORTANT:
When you remove the insulation from the cables or conductors be careful to
not cut the metal wires inside the insulation material.
NOTE: The photo in the procedure above shows wiring for OPW-FMS 924B Tank-Probes.
The inner conductor wires in the Smart-Sensor cables are different colors. Refer to the
illustration under Sensor Wiring below for the correct wiring for Smart-Sensors.
2. The
conductor
wires inside the cables are:
n
Power: The Tank-Probe conductor is Blue. The Smart-Sensor conductor is Red.
n
Signal: The Tank-Probe conductor is Brown The Smart-Sensor conductor is Black.
n
Ground: The Tank-Probe conductors are Black and Braided Shield. The Smart-Sensor
conductor is the Braided Shield.
3. Remove approximately 0.5 inches of insulation material from the ends of the conductor wires.
4. Remove approximately 1.5 inches of the cable
jacket
from the end of the Field Wiring cable (Belden
88760 or 88761) to show the three (3)
conductor
wires inside (Red = Power, Black = Signal, Braided
Shield = Ground).
5. Remove approximately 0.5 inches of insulation material from the ends of the Field Wiring Cable's Red
and Black
conductor
wires.
6. Put a tie wrap around both of the cables approximately 1 inch from the end of the cable
jacket
. Pull the
tie wrap tight and cut the unwanted tie material at the clamp.
7. Make three (3)
conductor
wire groups:
n
Twist the ends of the bare wires of the Power
conductor
wires together.
n
Twist the ends of the bare wires of the Signal
conductor
wires together.
n
Twist the ends of the bare wires of the Ground
conductor
wires together.
n
Put each of the twisted
conductor
wire groups into the open end of a wire-nut.
n
Turn each nut clockwise several turns until the wires are attached tightly.
REMINDER: See the illustration under Sensor Wiring below for the correct wiring for Smart-
Sensors.
NOTE:
Refer to the wiring diagrams in the product manual for more information about the
Tank-Probe or Smart-Sensor wiring.
8. Fold one of the assembled wire-nuts back as shown in the photo. The full wire-nut assembly can be
contained in the epoxy bag.
