2.3 Determining an appropriate location

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).

2.3.1 Environmental requirements

The transmitter’s environmental requirements include temperature, humidity, and vibration.

Temperature limits

Install the transmitter in an environment where ambient temperature is between –40 and +140 °F
(–40 and +60 °C). If possible, install the transmitter in a location that will prevent direct exposure to
sunlight.

Different ambient temperature requirements may apply when installing the transmitter in a hazardous
area. Refer to the approval documentation shipped with the transmitter or available on the Micro
Motion web site.

Humidity limits

Installing the Transmitter Output Wiring – AnalogSensor WiringBefore You Begin

Install the transmitter in an environment where relative humidity is between 5 and 95%,
non-condensing at 140 °F (60 °C).

Vibration limits

The transmitter meets IEC 68.2.6, endurance sweep, 5 to 2000 Hz, 50 sweep cycles at 1.0 g.

2.3.2 Hazardous area classifications

If you plan to mount the transmitter in a hazardous area:

• Verify that the transmitter has the appropriate hazardous area approval. Each transmitter has a
hazardous area approval tag attached to the transmitter housing.

• Ensure that any cable used between the transmitter and the sensor meets the hazardous area
requirements.

For more information about hazardous area classifications and requirements, see Section A.2.

2.3.3 Power source

Connect the transmitter to an AC or DC voltage source. The transmitter automatically recognizes the
source voltage.

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.

• Length and conductor diameter of the power cable must be sized to provide 18 VDC minimum
at the power terminals, at a load current of 0.5 amps. To size the cable, refer to Table 2-1 and
use the following formula as a guideline:

2.4 Mounting the transmitter

You can mount the transmitter in any orientation as long as the conduit and wiring openings do not
point upward. If possible, mount the transmitter so that there is at least 8–10″ (200–250 mm)
clearance at the rear of the housing to enable operator access to the wiring and power compartments.
For transmitter dimensions, see Appendix A.

Condensation or excessive moisture entering the transmitter could damage
the transmitter and result in measurement error or flowmeter failure.

To reduce the risk of measurement error or flowmeter failure:

• Ensure the integrity of gaskets and O-rings.

• Grease the O-rings every time the transmitter housing or core processor
housing is opened and closed.

• Do not mount the transmitter with the conduit openings pointing upward.

• Install drip legs on conduit or cable.

• Seal the conduit openings.

• Fully tighten the transmitter cover.

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.

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

Wiring the Transmitter to the Sensor

CAUTION

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 shield drain wires 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. Never ground to the core
processor’s mounting screw. Never ground the shield drain wires at the sensor junction
box.

b. Ground the cable braid on both ends, by terminating it inside the cable glands.

4. Ensure integrity of gaskets, grease all O-rings, then close the junction box housing and core
processor end-cap, and tighten all screws.

Damaging the wires that connect the transmitter to the sensor can cause
measurement error or flowmeter failure.

Installing the Transmitter Output Wiring – AnalogSensor WiringBefore You Begin

To reduce the risk of measurement error or flowmeter failure, when closing the
housings on the sensor and core processor, make sure that the wires are not
caught or pinched.

3.5 Wiring for remote core processor with remote transmitter installations

This task includes two subtasks:

• Subtask 1: Wiring the remote core processor to the transmitter (4-wire cable)

• Subtask 2: Wiring the sensor to the remote core processor (9-wire cable)

Subtask 1: Wire the remote core processor to the transmitter

1. 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 Subtask 1, Step 6.

• 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 Subtask 1, Step 6.

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

- Refer to Figure 3-5 to identify the cable gland to use for the 4-wire cable conduit
opening.

- Prepare the cable and apply shielded heat shrink to the cable (see Figure 3-6). 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 Subtask 1, Step 2.

- With armored cable, where the shield consists of braid, prepare the cable as described
below, but do not apply heat shrink. Proceed to Subtask 1, Step 2.

Output Wiring – Model 1700/2700 Intrinsically
Safe Transmitters

5.1 Overview

This chapter explains how to wire outputs for Model 1700 or 2700 transmitters with the intrinsically
safe outputs option board (output option code D).

Note: If you do not know what outputs option board is in your transmitter, see Section 1.4.

Intrinsically safe outputs require external power. “External power” means that the terminals must be
connected to an independent power supply. The output wiring instructions include power setup and
power wiring.

Note: The term “passive” is sometimes used to describe externally powered outputs.

Output wiring requirements depend on whether the transmitter will be installed in a safe area or a
hazardous area. This chapter describes several possible configurations:

• Section 5.3 describes wiring requirements for the outputs if the transmitter will be installed in
a safe area.

• Section 5.4 describes wiring requirements for the outputs if the transmitter will be installed in
a hazardous area.

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

5.4 Hazardous area output wiring

The following notes and diagrams are designed to be used as a guide for wiring the Model 1700 or
Model 2700 outputs for hazardous area applications.

5.4.1 Hazardous area safety parameters

The proper barrier selection will depend on what output is desired, which approval is applicable, and
many installation-specific parameters. The information that is provided about I.S. barrier selection is
intended as an overview. Refer to barrier manufacturers for more detailed information regarding the
use of their products. Application-specific questions should be addressed to the barrier manufacturer
or to Micro Motion.

Hazardous voltage can cause severe injury or death.

To reduce the risk of hazardous voltage, shut off the power before wiring the
transmitter outputs.

Installation Manual 37

Output Wiring – Model 1700/2700 Intrinsically Safe Transmitters

WARNING

A transmitter that has been improperly wired or installed in a hazardous area
could cause an explosion.

To reduce the risk of an explosion:

• Make sure the transmitter is wired to meet or exceed local code requirements.

• Install the transmitter in an environment that complies with the classification tag
on the transmitter. See Appendix A.

Hazardous area voltage

The Model 1700 or 2700 transmitter’s safety parameters require the selected barrier’s open-circuit
voltage to be limited to less than 30 VDC (Vmax = 30 VDC). This voltage is the combination of the
maximum safety barrier voltage (typically 28 VDC) plus an additional 2 VDC for HART
communications when communicating in the hazardous area.

Hazardous area current

The Model 1700 or 2700 transmitter’s safety parameters require the selected barrier’s short-circuit
currents to sum to less than 300 mA (Imax = 300 mA) for the milliamp outputs and 100 mA
(Imax = 100 mA) for the frequency/discrete output.

Hazardous area capacitance

The capacitance (Ci) of the Model 1700 or 2700 transmitter is 0.0005 μF. This value added to the
wire capacitance (Ccable) must be lower than the maximum allowable capacitance (Ca) specified by
the I.S. barrier. Use the following equation to calculate the maximum length of the cable between the
transmitter and the barrier:

Ci + Ccable ≤ Ca

Hazardous area inductance

The inductance (Li) of the Model 1700 or 2700 transmitter is 0.0 mH. This value plus the field wiring
inductance (Lcable), must be lower than the maximum allowable inductance (La) specified by the I.S.
barrier. The following equation can then be used to calculate the maximum cable length between the
transmitter and the barrier:

Li + Lcable ≤ La

Output Wiring – Model 2700 Configurable I/O
Transmitters

6.1 Overview

This chapter explains how to wire outputs for Model 2700 transmitters with the configurable
input/outputs board (output option code B or C).

Note: If you don’t know what outputs option board is in your transmitter, see Section 1.4.

Output wiring requirements depend on how you will configure the transmitter terminals. The
configuration options are shown in Table 6-1 and Figure 6-1.

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.

Note: The terms “active” and “passive” are sometimes used to describe internally and externally
powered outputs.

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

6.2 Channel configuration

The six terminals are divided into three pairs, and called Channels A, B, and C. Channel A is
terminals 1 and 2; Channel B is terminals 3 and 4; and Channel C is terminals 5 and 6. Variable
assignments are governed by channel configuration. Table 6-1 and Figure 6-1 show how each channel
may be configured, and the power options for each channel.

Output Wiring – Configurable I/O SpecificationsOutput Wiring – Fieldbus/PROFIBUSOutput Wiring – Intrinsically Safe

You can use a HART Communicator or ProLink II software to configure channels. To configure
channels, see the manual entitled Series 1000 and 2000 Transmitters Configuration and Use Manual.

Note: You cannot configure the following combination: Channel B = discrete output, Channel
C = frequency output. If you need both a frequency output and a discrete output, use the following:
Channel B = frequency output, Channel C = discrete output. For more information, see the manual
entitled Series 1000 and 2000 Transmitters Configuration and Use Manual.

6.4 Frequency output wiring

Frequency output wiring depends on whether you are wiring terminals 3 and 4 (Channel B) or
terminals 5 and 6 (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 6-5

• Channel B, external power – Figure 6-6

• Channel C, internal power – Figure 6-7

• Channel C, external power – Figure 6-8

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.
For more information, see the manual entitled Series 1000 and 2000 Transmitters Configuration and
