Wiring the Transmitter to the Sensor

8.At the transmitter, connect the four wires from the core processor to terminals 1–4 on the mating connector of the transmitter. See Figure 3-2.Never ground the shield, braid, or shield drain wire(s) at the transmitter. Refer to Figure 2-4.

Subtask 2: Wiring the sensor to the remote core processor

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.

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 core processor 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 core processor is provided below:

a.Identify the components shown in Figure 2-8.

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 core processor.

e.Insert the plugs into the sockets inside the lower conduit ring. See Figure 3-12.
