Transmitter Orientation and Power Supply
2.1 Overview
This chapter describes:
• Rotating the transmitter on the sensor (optional)
• Rotating the user interface module on the transmitter (optional)
• Power supply requirements and wiring
2.2 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.
Power Supply I/O Wiring – DP and DNI/O Wiring – ANBefore You Begin
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.
2.3 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. 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.

2.4 Rotating the user interface module on the transmitter (optional)
Do not rotate the housing more than 360°. Excessive rotation can damage the wiring and cause
measurement error or flowmeter failure.
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.
Removing the transmitter housing cover in a hazardous area while the transmitter is powered up can
cause an explosion. Shut off power to the transmitter before removing the housing cover in a
hazardous area.
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.
3. On the back of the user interface module, four user interface connectors are provided. Rotate
the user interface module to the desired position and plug it into the user interface connector
on the transmitter. (See Figure 2-3 for another view of the user interface connector on the
transmitter.)
4. Tighten the user interface screws.
5. Replace the transmitter housing cover and tighten the transmitter housing cover screws.
6. Restore power to the transmitter if required.

2.5 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 Chapter 4.

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. (This assumes a single transmitter per cable.
Connecting multiple transmitters to a single cable should generally be avoided.) To size the
cable, refer to Table 2-1 and use the following formula as a guideline:
Table 2-1 Typical power cable resistances at 68 °F (20 °C)
Gauge Resistance
14 AWG 0.0050 Ω/foot
