• Ground the flowmeter components (see Section 2.5)

• Supply power to the flowmeter (see Section 2.6)

2.2 Determining an appropriate locationTo determine an appropriate location for the transmitter, you must consider the temperature requirements of the transmitter and core processor, hazardous area issues, location of power source, cable lengths, and accessibility for maintenance.

Your flowmeter will match one of the configurations shown in Figure 2-1. Mounting, sensor wiring, and grounding requirements depend on this configuration.

2.2.1 Temperature requirements

Install the transmitter in an environment where ambient temperature is between –40 and +131 °F (–40 and +55 °C).

Different ambient temperature requirements may apply, depending on your installation. Refer to the ATEX or CSA installation manuals shipped with the transmitter or available on the Micro Motion web site.

2.2.2 Hazardous area classifications

The Model 1500 or 2500 transmitter is designed for installation in a safe area. It can be connected to a core processor located in a hazardous area. If you plan to connect the transmitter to a core processor located in a hazardous area, ensure that any cable used between the transmitter and the sensor meets the hazardous area requirements.

For more information about hazardous area classifications, see Appendix A.

2.2.3 Power sourceThe transmitter must be connected to a DC voltage source. Do not use an AC power supply.


Installing the Transmitter continued

The following requirements apply:

• 19.2 to 28.8 VDC at the power terminals, at a load current of 330 mA

• 6.3 watts maximum

• At startup, the transmitter power source must provide a minimum of 1.0 amp of short-term current per transmitter

To size the cable, refer to Table 2-1 and use the following formula as a guideline:

2.5 Grounding the flowmeter componentsGrounding requirements depend on the installation configuration (see Figure 2-1).

If national standards are not in effect, follow these transmitter grounding guidelines:

• Use copper wire, 14 AWG (2,5 mm2) or larger wire size, for grounding.

• Keep all ground leads as short as possible, less than 1 Ω impedance.

• Connect ground leads directly to earth, or follow plant standards.

2.5.1 Grounding for 4-wire remote installations

In 4-wire remote installations, one ground is required for the sensor / core processor assembly, and a separate ground is required for the transmitter.

To ground the transmitter, ground the DIN rail. A rail clip in the base of the transmitter housing grounds the transmitter to the DIN rail.

The preferred method for grounding the sensor / core processor assembly is through the piping, if the joints in the pipeline are ground-bonded. If the sensor is not grounded via the piping, connect a ground wire to the internal or external grounding screw on the core processor. See the sensor documentation.

2.5.2 Grounding for remote core processor with remote transmitter installations

In remote core processor with remote transmitter installations, the sensor, core processor, and transmitter must be grounded separately.

To ground the transmitter, ground the DIN rail. A rail clip in the base of the transmitter housing grounds the transmitter to the DIN rail.

Ground the core processor according to applicable local standards, using either the internal or external ground screw.

The preferred method for grounding the sensor is through the piping, if the joints in the pipeline are ground-bonded. If the sensor is not grounded via the piping, connect a ground wire to the internal or external grounding screw on the sensor junction box. See the sensor documentation.

CAUTION

Improper grounding could cause measurement error.

To reduce the risk of measurement error:

• Ground the transmitter to earth, or follow ground network requirements for the facility.

• For installation in an area that requires intrinsic safety, refer to Micro Motion ATEX or CSA documentation, shipped with the transmitter or available from the Micro Motion web site.

• For hazardous area installations in Europe, refer to standard EN 60079-14 if national standards do not apply.



2.6 Supplying powerIn all installations, power must be provided to the transmitter. Refer to Section 2.2.3 for information on the transmitter’s power supply requirements.

Connect the power supply to terminals 11 and 12. Terminate the positive wire on terminal 11 and the negative wire on terminal 12. See Figure 2-6.

Terminals 13 and 14 are used to jumper power to another Model 1500 or 2500 transmitter. A maximum of five transmitters can be jumpered together.

Chapter 3Wiring the Transmitter to the Sensor

3.1 Overview

This chapter describes how to connect the Micro Motion Model 1500 and 2500 transmitters to a Micro Motion sensor.

Wiring requirements between the sensor and transmitter depend on the installation configuration (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.

• If you have a remote core processor with remote transmitter installation, review the information on both 4-wire and 9-wire cable in Section 3.2, then follow the instructions in Section 3.4.

3.2 Cable typesThis section describes the types of 4-wire cable and 9-wire cable that can be used for 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.

User-supplied 4-wire cable must meet the following requirements:

• Twisted pair construction

• The gauge requirements as described in Table 2-2

• The applicable hazardous area requirements, if the core processor is installed in a hazardous area (see the ATEX or CSA documents shipped with the transmitter or available on the Micro Motion web site)

CAUTION

Large electromagnetic fields can interfere with flowmeter communication signals.

Improper installation of cable or conduit can cause measurement error or flowmeter failure. To reduce the risk of measurement error or flowmeter failure, keep cable or conduit away from devices such as transformers, motors, and power lines which produce large electromagnetic fields.


Wiring the Transmitter to the Sensor continued

3.2.2 9-wire cableMicro Motion offers three types of 9-wire cable: jacketed, shielded, and armored. Refer to Micro Motion’s 9-Wire Flowmeter Cable Preparation and Installation Guide for detailed descriptions of these cable types and for assistance in selecting the appropriate cable for your installation.

3.3 Wiring for 4-wire remote installations

To connect the cable, follow the steps below.

1. Prepare the cable as described in the sensor documentation.

2. Connect the cable to the core processor as described in the sensor documentation.

3. To connect the cable to the transmitter:

a. 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.

b. Connect the four wires from the core processor to terminals 1–4 on the transmitter. See Figure 3-1. Do not ground the shield, braid, or drain wire(s) at the transmitter.

Figure 3-1 4-wire cable between core processor and transmitter

Step 1 Wire the remote core processor to the transmitter1. Use one of the following methods to shield the wiring from the core processor to the

transmitter:

• If you are installing unshielded wiring in continuous metallic conduit that provides 360° termination shielding for the enclosed wiring, go to Step 6 of the wiring instructions (page 15).

• If you are installing a user-supplied cable gland with shielded cable or armored cable, terminate the shields in the cable gland. Terminate both the armored braid and the shield drain wires in the cable gland. Go to Step 6 of the wiring instructions (page 15).

• If you are installing a Micro Motion-supplied cable gland at the core processor housing:

- Prepare the cable and apply shielded heat shrink to the cable (see Figure 3-2). The shielded heat shrink provides a shield termination suitable for use in the gland when using cable whose shield consists of foil and not a braid. Proceed to Step 2 below.

- With armored cable, where the shield consists of braid, prepare the cable as described below, but do not apply heat shrink. Proceed to Step 2 below.

2. Remove the cover from the core processor.

3. Slide the gland nut and the clamping insert over the cable.

Figure 3-2 Micro Motion cable gland and heat shrink

4. For connection at the core processor housing, prepare shielded cable as follows (for armored cable, omit steps d, e, f, and g):

a. Strip 4 1/2 inches (114 mm) of cable jacket.

b. Remove the clear wrap that is inside the cable jacket, and remove the filler material between the wires.

c. Remove the foil shield that is around the insulated wires, leaving 3/4 inch (19 mm) of foil or braid and drain wires exposed, and separate the wires.

d. Wrap the shield drain wire(s) around the exposed foil twice. Cut off the excess wire. See Figure 3-3.

Chapter 5Model 2500 – Wiring the Outputs

5.1 Overview

This section describes how to wire the outputs for the Model 2500 transmitter.

Note: For information on wiring outputs for the Model 1500 transmitter, see Chapter 4.

5.2 Model 2500 outputs

Output wiring requirements depend on how you will configure the transmitter terminals. The configuration options are shown in Table 5-1 and Figure 5-1.

Note: The term “channel” is used to refer to the output terminal pairs.

If Channel B is configured as a frequency output or discrete output, it can also be configured to use either internal or external power. Channel C can be configured to use either internal or external power, independent of its output configuration.

• “Internal power” means that the terminals are powered automatically by the transmitter. The output wiring instructions do not include power setup and power wiring.

• “External power” means that the terminals must be connected to an independent power supply. The output wiring instructions include power setup and power wiring.

It is the user’s responsibility to verify that his/her specific installation meets the local and national safety requirements and electrical codes.

Table 5-1 Terminal configuration options

Output option Power option

Terminals Channel mA Frequency(1) (2)

(1) Because discrete output 1 uses the same circuitry as the frequency output, it is not possible to configure both a frequency ouput and discrete output 1. If both a frequency output and a discrete output are required, configure Channel B as the frequency output and Channel C as the discrete output (discrete output 2).

(2) Can be configured for active high or active low polarity. Default is active high.

5.2.2 Frequency output wiringFrequency output wiring depends on whether you are wiring terminals 23 and 24 (Channel B) or terminals 31 and 32 (Channel C), and also on whether you have configured the terminals for internal or external power. The following diagrams are examples of proper wiring for these configurations:

• Channel B, internal power – Figure 5-5

• Channel B, external power – Figure 5-6

• Channel C, internal power – Figure 5-7

• Channel C, external power – Figure 5-8

Note: If both Channel B and Channel C are configured for frequency output, the Channel C signal is generated from the Channel B signal, with a user-specified phase shift. The signals are electrically isolated but not independent. This configuration is used to support dual-pulse and quadrature modes. See the manual entitled Transmitter Configuration and Use: Series 1000 and 2000 Transmitters for more information.
