Wiring the Transmitter to the Sensor

3.4Wiring for 9-wire remote installations

If you chose a 9-wire remote installation (see Figure 2-1), a 9-wire cable must be used to connect the junction box on the sensor to the core processor on the transmitter/core processor assembly.

CAUTION

Allowing the shield drain wires to contact the sensor junction box can cause flowmeter errors.

Do not allow the shield drain wires to contact the sensor junction box.

To connect the cable, follow the steps below:

1.Refer to Micro Motion’s 9-Wire Flowmeter Cable Preparation and Installation Guide for instructions on cable shielding and preparation:

•At the sensor end, follow the instructions for your cable type.

•At the transmitter end, follow the instructions for your cable type with an MVD transmitter.

2.To connect the wires, refer to Micro Motion’s 9-Wire Flowmeter Cable Preparation and Installation Guide and follow the instructions for your sensor with an MVD transmitter. Additional information for connecting the wires at the transmitter is provided below:

a.Identify the components shown in Figure 2-6.

b.Remove the end-cap.

c.Insert the 9-wire cable through the conduit opening.

d.Connect the wires to the plugs supplied with the transmitter.

e.Insert the plugs into the sockets inside the lower conduit ring. See Figure 3-4.
