4. Route the cable through the gland on the Base Enclosure and pull the cable up
through the Base Enclosure to allow enough slack to strip the cable wire.
5. Strip the outer insulation, outer shield, and inner insulation to just inside the cable
gland using a wire stripper. Verify that insulation of individual wires were not cut
while removing outer layers. Strip each wire 1/4 inch and wire them to the
Acquisition Module terminal block. Check the label number (i.e. A1) on the
Acquisition Module and match it with the label on the cable. Securely tighten the
mounting screws of terminal block J1 and J2 as shown in
Figure 3-18: Model 3414 Ultrasonic Meter Acquisition Module wiring
6. Only connect wires for Chords A1, A2, B1 and B2 for 3412 meter applications or A1
and A2 for 3411 meter applications. The relative position of the contacts is shown
on the Acquisition Module label adjacent to the terminal block. When terminating
the connector wires, ensure that the contacts clamp on the bare wires and not on
the wire insulation. Leave the connector plugged into the Acquisition Module while
terminating the individual wires.
7. Once the transducers are wired correctly, tighten the cable gland so that the
transducer cable is held securely in place. Pull the cable back through the gland to
remove the slack and configure the cable to follow the same path of the existing
cable (see
Transducer cable removal and installation
8. Repeat
if you are replacing other cables.
9. Once all of the cables are replaced, dress with tie wraps (P/N 2-4-9158-001) in
groups of two; A1 and C1, D1 and B1, A2 and C2, D2 and B2. Install one cable tie
three inches from the Base Enclosure and another near the point the cables start to
bend and separate out into their respective port (see
10. Inspect the Transmitter Electronics Enclosure gasket for wear and replace it if
necessary.
11. If replacing the gasket, lubricate it with Molykote 111
(P/N 2-9-9960-135).
