This section describes:

• Rotating the transmitter on the sensor (optional)

• Rotating the user interface module on the transmitter (optional)

• Power supply requirements and wiring

2.1 Moisture protection

When rotating or wiring the transmitter, guard against condensation or excessive moisture
inside the transmitter housing. Be sure that the conduit openings are completely sealed
after you perform all installation and wiring procedures.

CAUTION!

Improperly sealed housings can expose electronics to moisture, which can cause measurement error
or flowmeter failure. Install the meter so that the conduit openings do not point upward, and install
drip legs in conduit or cable. Inspect and grease all gaskets and O-rings. Fully close and tighten all
housing covers and conduit openings.

2.2 Rotating the transmitter on the sensor (optional)

For easier access to the user interface or the wiring terminals, the transmitter can be
rotated on the sensor in 45° increments, for eight different orientations.

To rotate the transmitter on the sensor:

1. Unscrew the clamp that holds the transmitter to the feedthrough.

See Figure 2-1.

2. Gently lift the transmitter on the feedthrough until it disengages from the notches on

the feedthrough. You will not be able to remove the transmitter completely.

3. Rotate the transmitter to the desired position.

4. Lower the transmitter, sliding it onto the notches on the feedthrough.

5. Replace the clamp and tighten the screw.

CAUTION!

Do not rotate the housing more than 360°. Excessive rotation can damage the wiring and

cause measurement error or flowmeter failure.

2.3 Rotating the user interface module on the transmitter (optional)

For easier access, you can rotate the user interface module (whether or not the transmitter
has an LCD display) up to 360° in 90° increments.

WARNING!

Shut off power to the transmitter before you remove the housing cover in a hazardous area, as this
could cause an explosion.

To rotate the user interface module on the transmitter:

1. Remove power from the unit.

2.4 Power supply requirements

Model 2400S Analog and Model 2400S PROFIBUS-DP transmitters can accept either AC or
DC power. The transmitter automatically recognizes the source voltage. Power supply
requirements are:

• AC power:

- 85–265 VAC

-50/60 Hz

- 4 watts typical, 7 watts maximum

• DC power:

- 18–100 VDC

- 4 watts typical, 7 watts maximum

The Model 2400S DeviceNet transmitter is powered from the DeviceNet network per the
DeviceNet specification. There is no need to connect separate power-supply wiring for the
Model 2400S DeviceNet transmitter. Skip to Section 4.

2.5 DC power requirements for Model 2400S Analog and PROFIBUS-DP transmitters

If you are using DC power with a Model 2400S Analog or PROFIBUS-DP transmitter, the
following requirements apply:

• At startup, the transmitter power source must provide a minimum of 1 A 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 A. (This assumes a single
transmitter per cable. Connecting multiple transmitters to a single cable should
generally be avoided.) To size the cable, see Table 2-1 and use the following formula as
a guideline:

2.6 Wire the power supply

To wire the power supply:

1. Remove the transmitter housing cover and user interface module as described in

Section 2.3.

2. Unscrew the warning flap screw and raise the warning flap.

Figure 2-3 shows the warning flap in the open position.

3. Connect the power supply wires to terminals 9 and 10, as shown in Figure 2-3.

4. Ground the power supply to the transmitter’s internal grounding screw, shown in

Figure 2-3.

5. Lower the warning flap and tighten the warning flap screw.

6. (Optional). Install a user-supplied switch 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.

This section describes how to wire I/O for Model 2400S PROFIBUS-DP and DeviceNet
transmitters.

Note:

To wire I/O for Model 2400S Analog transmitters, see Chapter 3.

Important:

Follow all corporate, local, and national safety requirements and electrical codes.

4.1 Moisture protection

When rotating or wiring the transmitter, guard against condensation or excessive moisture
inside the transmitter housing. Be sure that the conduit openings are completely sealed
after completing all installation and wiring procedures.

CAUTION!

Improperly sealed housings can expose electronics to moisture, which can cause measurement error
or flowmeter failure. Install the meter so that the conduit openings do not point upward, and install
drip legs in conduit or cable. Inspect and grease all gaskets and O-rings. Fully close and tighten all
housing covers and conduit openings.

4.2 I/O wiring for Model 2400S PROFIBUS-DP transmitters

WARNING!

Follow all corporate, national, and local safety regulations.

To connect the I/O wiring for a 2400S PROFIBUS-DP transmitter:

1. Remove the user interface cover and user interface module.

For instructions, see Section 2.2.

2. Wire the transmitter to the PROFIBUS-DP segment according to the diagram in Figure

4-1.

3. Replace the user interface module and user interface cover.

COM A (green) COM B (red)

Note:

Do not open the power compartment unless you are also wiring the power supply.

Note:

Ground the PROFIBUS cable shield at both ends. At the 2400S, ground the cable shield in an appropriate cable gland. If
using an optional PROFIBUS-DP Eurofast M12 connector, ground the cable shield using the threads of the connector.

WARNING!

Hazardous voltage can cause severe injury or death. Keep the power supply compartment
closed while wiring the transmitter outputs, or shut off power to the transmitter.

WARNING!

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

www.micromotion.com, or by phoning the Micro Motion Customer Service department.

B.1 New and unused equipment

Only equipment that has not been removed from the original shipping package will be
considered new and unused. New and unused equipment requires a completed Return
Materials Authorization form.

B.2 Used equipment

All equipment that is not classified as new and unused is considered used. This equipment
must be completely decontaminated and cleaned before being returned.

Used equipment must be accompanied by a completed Return Materials Authorization
form and a Decontamination Statement for all process fluids that have been in contact
with the equipment. If a Decontamination Statement cannot be completed (e.g., for
food-grade process fluids), you must include a statement certifying decontamination and
documenting all foreign substances that have come in contact with the equipment.
