Installing the Transmitter 2.3 Determining an appropriate location 2.3.1 Before You Begin To determine an appropriate location for the transmitter, you must consider the environmental requirements of the transmitter and core processor, hazardous area classification, location of power source, cable lengths, accessibility for maintenance, and visibility of the display (if the transmitter is equipped with a display).
Installing the Transmitter DC power requirements Note: These requirements assume a single transmitter per cable. Connecting multiple transmitters to a single cable should be avoided. If you are using DC power, the following requirements apply: • 18–100 VDC • 6 watts typical, 11 watts maximum • At startup, the transmitter power source must provide a minimum of 1.5 amps of short-term current per transmitter.
Installing the Transmitter 2.3.4 Maximum cable lengths Table 2-2 Before You Begin This requirement does not apply to integral installations (see Figure 2-1). For other installation types (see Figure 2-1), maximum cable length between flowmeter components depends on the installation type and the cable type. Refer to Figure 2-1, then see Table 2-2.
Installing the Transmitter 2.4.1 Integral installations If you chose an integral installation (see Figure 2-1), there are no special mounting instructions for the transmitter. You can rotate an integrally mounted transmitter up to 360° in 90° increments, to one of four possible positions on the core processor base. See Figure 2-2.
Installing the Transmitter Before You Begin 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. 2.4.2 4-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.

Installing the Transmitter To mount the transmitter/core processor assembly: Before You Begin 1. Identify the components shown in Figure 2-6. For dimensions, see Appendix A. 2. If desired, re-orient the transmitter on the bracket. a. Loosen each of the four cap screws (4 mm). b. Rotate the bracket so that the transmitter is oriented as desired. c. Tighten the cap screws, torquing to 30 to 38 in-lbs (3 to 4 N-m). 3. Attach the mounting bracket to an instrument pole or wall.
Installing the Transmitter Figure 2-7 Remote core processor – Wall mount or pipe mount Mounting bracket (wall mount) Mounting bracket (pipe mount) To mount the core processor: 1. Identify the components shown in Figure 2-8. For dimensions, see Appendix A. 2. If desired, reorient the core processor housing on the bracket. a. Loosen each of the four cap screws (4 mm). b. Rotate the bracket so that the core processor is oriented as desired. c.
Installing the Transmitter 2.6 Grounding the flowmeter components Before You Begin Grounding requirements depend on the installation type (see Figure 2-1). Grounding methods for each flowmeter component are listed in Table 2-3. CAUTION Improper grounding could cause measurement error. To reduce the risk of measurement error: • • Installing the Transmitter • Ground the transmitter to earth, or follow ground network requirements for the facility.
Installing the Transmitter 2.7 Supplying power In all installations, power must be provided to the transmitter. Refer to Section 2.3.3 for information on the transmitter’s power supply requirements. A user-supplied switch may be installed in the power supply line. For compliance with low-voltage directive 2006/95/EC (European installations), a switch in close proximity to the transmitter is required. Connect the power supply to terminals 9 and 10, under the Warning flap.
Installing the Transmitter Before You Begin WARNING Using a dry cloth to clean the display cover can cause static discharge, which could result in an explosion in an explosive atmosphere. To reduce the risk of an explosion, always use a damp cloth to clean the display cover in an explosive atmosphere. To rotate the display, follow the instructions below: 1. Power down the transmitter. 2. Remove the end-cap clamp by removing the cap screw. See Figure 2-10. 3.

3.1 Before You Begin Chapter 3 Wiring the Transmitter to the Sensor Overview This chapter describes how to connect Micro Motion Model 1700 and 2700 transmitters to a Micro Motion sensor. Wiring requirements between the sensor and transmitter depend on the installation type (see Figure 2-1). • If you have a 4-wire remote transmitter installation, review the information on 4-wire cable in Section 3.2, then follow the instructions in Section 3.3.
Wiring the Transmitter to the Sensor 3.2.1 4-wire cable Micro Motion offers two types of 4-wire cable: shielded and armored. Both types contain shield drain wires.

Wiring the Transmitter to the Sensor 3.4 Wiring 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.
Wiring the Transmitter to the Sensor If using jacketed cable: If using shielded or armored cable: a. Ground the shield drain wires (the black wire) only on the core processor end, by connecting it to the ground screw inside the lower conduit ring. Never ground to the core processor’s mounting screw. Never ground the shield drain wires at the sensor junction box. Before You Begin a.

Remove the cover from the core processor housing. 3. Slide the gland nut and the clamping insert over the cable.
Wiring the Transmitter to the Sensor Figure 3-7 Wrapping the shield drain wires Before You Begin e. Place the shielded heat shrink over the exposed shield drain wire(s). The tubing should completely cover the drain wires. See Figure 3-8. Figure 3-8 Installing the Transmitter f. Without burning the cable, apply heat (250 °F or 120 °C) to shrink the tubing. Applying the heat shrink g. Position gland clamping insert so the interior end is flush with the heat shrink.
Wiring the Transmitter to the Sensor Figure 3-10 Gland body and core processor housing 5. Insert the wires through the gland body and assemble the gland by tightening the gland nut. 6. Identify the wires in the 4-wire cable. The 4-wire cable supplied by Micro Motion consists of one pair of 18 AWG (0,75 mm2) wires (red and black), which should be used for the VDC connection, and one pair of 22 AWG (0,35 mm2) wires (green and white), which should be used for the RS-485 connection.
Wiring the Transmitter to the Sensor Subtask 2: Wiring the sensor to the remote core processor CAUTION Before You Begin 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. Allowing the shield drain wires to contact the sensor junction box can cause flowmeter errors.
Wiring the Transmitter to the Sensor If using jacketed cable: a. Ground the shield drain wires (the black wire) only on the core processor end, by connecting it to the ground screw inside the lower conduit ring. Never ground to the core processor’s mounting screw. Never ground the cable at the sensor junction box. If using shielded or armored cable: a. Ground the shield drain wires (the black wire) only on the core processor end, by connecting it to the ground screw inside the lower conduit ring.
