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 all installation and
wiring procedures have been performed.
CAUTION
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:
•
•
•
•
•
2.3
Do not mount the sensor so that the conduit openings on the transmitter point
upward.
Ensure the integrity of gaskets and O-rings.
Grease the O-rings every time the transmitter housing is opened and closed.
Install drip legs on conduit or cable.
Seal the conduit openings.
Fully tighten all covers.

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.
I/O Wiring – DP and DN
To rotate the transmitter on the sensor:
1. Referring to Figure 2-1, unscrew the clamp that holds the transmitter to the feedthrough.
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
Excessive rotation of the housing on the feedthrough can cause wiring
damage and result in measurement error or flowmeter failure.
To reduce the risk of damaging internal wiring, do not rotate the housing more than
360°. You can rotate the transmitter either clockwise or counter-clockwise to reach
the desired position.

Rotating the user interface module on the transmitter (optional)
For easier access, the user interface module (whether or not the transmitter has an LCD display) can
be rotated on the transmitter up to 360° in 90° increments.
To rotate the user interface module on the transmitter:
1. Remove power from the unit.
WARNING
Removing the transmitter housing cover in a hazardous area while the
transmitter is powered up can cause an explosion.
To avoid the risk of an explosion, remove power from the transmitter before
removing the transmitter housing cover.
2. Referring to Figure 2-2, remove the transmitter housing cover and user interface module:
a. Loosen the four transmitter housing cover screws.
b. Remove the transmitter housing cover.
c. Loosen the two user interface screws.
d. Gently lift the user interface module, disengaging it from the user interface connector on
the transmitter.

2.5.1
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. To size the cable, refer to Table 2-2 and use
the following formula as a guideline:
MinimumSupplyVoltage = 18V + ( CableResistance × CableLength × 0.5A )

(1) These values include the resistance of both high and low conductors in a cable.
Example
The transmitter is mounted 350 feet from a DC power supply. If you want to use
16 AWG cable, calculate the required voltage at the DC power supply as follows:
MinimumSupplyVoltage = 18V + ( CableResistance × CableLength × 0.5A )
MinimumSupplyVoltage = 18V + ( 0.0080 Ohms/ft × 350 ft × 0.5A )
MinimumSupplyVoltage = 19.4V
2.6
Wiring the power supply
Note: This procedure is required only for Model 2400S Analog and PROFIBUS-DP transmitters.
To wire the power supply:
1. Remove the transmitter housing cover and user interface module as described in Section 2.4.
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.

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 IS 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.

The Model 2400S transmitter’s safety parameters require the selected barrier’s open-circuit voltage to
be limited to less than 36 VDC (Vmax = 36 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.
I/O Wiring – AN
Hazardous area voltage
Hazardous area current
The Model 2400S transmitter’s safety parameters require the selected barrier’s short-circuit currents
to sum to less than 500 mA (Imax = 500 mA) for the milliamp outputs and 500 mA (Imax = 500 mA) for
the frequency/discrete output.
I/O Wiring – DP and DN
Hazardous area capacitance
The capacitance (Ci) of the Model 2400S transmitter is 1.1 nF. This value added to the wire
capacitance (Ccable) must be lower than the maximum allowable capacitance (Ca) specified by the IS
barrier. Use the following equation to calculate the maximum length of the cable between the
transmitter and the barrier:
C i + C cable ≤ C a

Hazardous area inductance
The inductance (Li) of the Model 2400S 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 IS
barrier. The following equation can then be used to calculate the maximum cable length between the
transmitter and the barrier:

Note: To wire I/O for Model 2400S Analog transmitters, see Chapter 3.
4.2
Moisture protection
Power Supply
It is the user’s responsibility to verify that the specific installation meets the local and national safety
requirements and electrical codes.
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 all installation and
wiring procedures have been performed.
CAUTION
Condensation or excessive moisture entering the transmitter could damage
the transmitter and result in measurement error or flowmeter failure.
I/O Wiring – AN
To reduce the risk of measurement error or flowmeter failure:
•
•
•
•
•
•
Do not mount the sensor so that the conduit openings on the transmitter point
upward.
Ensure the integrity of gaskets and O-rings.
Grease the O-rings every time the transmitter housing is opened and closed.
Install drip legs on conduit or cable.
Seal the conduit openings.
Fully tighten all covers.

I/O wiring for Model 2400S PROFIBUS-DP transmitters
To connect the I/O wiring for a 2400S PROFIBUS-DP transmitter:
1. Remove the user interface cover and user interface module. See Section 2.4 for instructions.
2. Wire the transmitter to the PROFIBUS-DP segment according to the diagram in Figure 4-1.
Follow all local safety regulations.
3. Replace the user interface module and user interface cover.
Note: It is not necessary to open the power compartment to wire the outputs. Do not open the power
compartment unless you are also wiring the power supply.
Note: The PROFIBUS cable shield is required to be grounded at both ends. At the 2400S, ground the
cable shield in an appropriate cable gland. If an optional PROFIBUS-DP Eurofast M12 connector is
used, the cable shield is grounded via the threads of the connector.
WARNING
Hazardous voltage can cause severe injury or death.
To avoid the risk of hazardous voltage, shut off the power before wiring the
transmitter outputs.
