November 2019 Quick Start Guide
3.5 Connect the wiring and power up
Use copper wire of sufficient size to ensure the voltage across the
transmitter power terminals does not drop below 9 Vdc. Power supply
voltage can be variable, especially under abnormal conditions such as when
operating on battery backup. A minimum of 12 Vdc under normal operating
conditions is recommended. Shielded twisted pair type A cable is
recommended.
Use the following steps to wire the transmitter:
Procedure
1. To power the transmitter, connect the power leads to the terminals
indicated on the terminal block label.
Note
The Rosemount 2051 power terminals are polarity insensitive, which
means the electrical polarity of the power leads does not matter
when connecting to the power terminals. If polarity sensitive devices
are connected to the segment, terminal polarity should be followed.
When wiring to the screw terminals, the use of crimped legs is
recommended.
2. Ensure full contact with terminal block screw and washer. When
using a direct wiring method, wrap wire clockwise to ensure it is in
place when tightening the terminal block screw. No additional power
is needed.
Note
The use of a pin or a ferrule wire terminal is not recommended as the
connection may be more susceptible to loosening over time or under
vibration.
3. Ensure proper grounding. It is important the instrument cable shield
be:
4. Trimmed close and insulated from touching the transmitter housing.
5. Connected to the next shield if cable is routed through a junction
box.
6. Connected to a good earth ground at the power supply end.
7. If transient protection is needed, refer to section “Signal ground
wiring” for grounding instructions.
8. Plug and seal unused conduit connections.
9. Reattach the transmitter covers. It is recommended that the cover be
tightened until there is no gap between the cover and the housing.

3.5.1 Signal ground wiring
Do not run signal wiring in conduit or open trays with power wiring, or near
heavy electrical equipment. Grounding terminations are provided on the
outside of the electronics housing and inside the terminal compartment.
These grounds are used when transient protect terminal blocks are installed
or to fulfill local regulations.
Procedure
1. Remove the field terminals housing cover.
2. Connect the wiring pair and ground as indicated in Figure 3-5.
a) Trim the cable shield as short as practical and insulate from
touching the transmitter housing.
12 Rosemount 2051HT
November 2019 Quick Start Guide
Note
Do NOT ground the cable shield at the transmitter; if the cable shield
touches the transmitter housing, it can create ground loops and
interfere with communications.
3. Continuously connect the cable shields to the power supply ground.
a) Connect the cable shields for the entire segment to a single
good earth ground at the power supply.
Note
Improper grounding is the most frequent cause of poor segment
communications.
4. Replace the housing cover. It is recommended that the cover be
tightened until there is no gap between the cover and the housing.
a) The covers must only be capable of being released or
removed with the aid of a tool to comply with applicable
ordinary locations requirements.
5. Plug and seal unused conduit connections.
Note
The Rosemount 2051HT polished 316 SST housing only provides
ground termination inside the terminal compartment.
3.5.2 Power supply
The transmitter requires between 9 and 32 Vdc (9 and 30 Vdc for intrinsic
safety) to operate and provide complete functionality.
3.5.3 Power conditioner
A Fieldbus segment requires a power conditioner to isolate the power
supply, filter, and decouple the segment from other segments attached to
the same power supply.
3.5.4 Grounding
Signal wiring of the Fieldbus segment cannot be grounded. Grounding out
one of the signal wires will shut down the entire Fieldbus segment.
3.5.5 Shield wire ground
To protect the Fieldbus segment from noise, grounding techniques for
shield wire require a single grounding point for shield wire to avoid creating
a ground loop. Connect the cable shields for the entire segment to a single
good earth ground at the power supply.
Quick Start Guide 13
Quick Start Guide November 2019
3.5.6 Signal termination
For every Fieldbus segment a terminator should be installed at the beginning
and at the end of each segment.
3.5.7 Locating devices
Devices are frequently installed, configured, and commissioned over time by
different personnel. A “Locate Device” capability uses the LCD display (when
installed) to assist personnel in finding the desired device.
From the device Overview screen, select the Locate Device button. This will
launch a method allowing the user to display a “Find me” message or enter a
custom message to display on the device LCD display. When the user exits
the “Locate Device” method, the device LCD display automatically returns to
normal operation.
Note
Some hosts do not support “Locate Device” in the DD.
3.6 Configure
Each Foundation Fieldbus host or configuration tool has a different way of
displaying and performing configurations. Some use device descriptions
(DD) or DD methods for configuration and to display data consistently
across platforms. There is no requirement that a host or configuration tool
support these features. Use the following block examples to do basic
configuration to the transmitter. For more advanced configurations, see the
Rosemount 2051 Reference Manual.
Note
DeltaV™ users should use DeltaV Explorer for the Resource and Transducer
blocks and Control Studio for the Function Blocks.
