Installing the Transmitter

CAUTION

Twisting the core processor will damage the sensor.

To reduce the risk of damaging the sensor, do not allow the core processor to rotate.

2.4.24-wire remote or remote core processor with remote transmitter installations

If you chose the 4-wire remote or the remote core processor with remote transmitter installation (see Figure 2-1), see Figure 2-3 for a diagram of the mounting bracket supplied with the transmitter. Both pipe mounting and wall mounting are shown. Ensure that the transmitter is mounted and oriented in a way that will allow easy access to the terminals and to the display (if your transmitter has a display).

Before You Begin

Installing the Transmitter

Mounting bracket (wall mount)

To mount the transmitter:

Mounting bracket (pipe mount)

Note: If possible, maintain 8–10(200–250 mm) clearance at the rear of the transmitter.

Sensor Wiring

1.Identify the components shown in Figure 2-4. For dimensions, see Appendix A.

2.If desired, re-orient the transmitter on the bracket.

a.Remove the junction end-cap from the junction housing.

b.Loosen each of the four cap screws (4 mm) inside the junction housing.

c.Rotate the bracket so that the transmitter is oriented as desired.

d.Tighten the cap screws, torquing to 30 to 38 in-lbs (3 to 4 N-m).

e.Replace the junction end-cap.

3.Attach the mounting bracket to an instrument pole or wall. For pipe mount, two user-supplied U-bolts are required. Contact Micro Motion to obtain a pipe-mount installation kit if required.
