1.1  Safety messages

WARNING
Explosions
Explosions could result in death or serious injury.
Installation of device in an explosive environment must be in accordance with appropriate local, national, and international standards, codes, and practices. Review the approvals section of the Rosemount 3051 Manual for any restrictions associated with a safe installation.
In an explosionproof/flameproof installation, do not remove the transmitter covers when power is applied to the transmitter.
WARNING
Process leaks
Process leaks may cause harm or result in death.
To avoid process leaks, only use the O-ring designed to seal with the corresponding flange adapter.
WARNING
Electrical shock
Electrical shock can result in death or serious injury.
Avoid contact with the leads and terminals. High voltage that may be present on leads can cause electrical shock.
Quick Start Guide 3
Page 4
WARNING
Conduit/cable entries
Unless otherwise marked, the conduit/cable entries in the housing enclosure use a ½–14 NPT form. Only use plugs, adapters, glands, or conduit with a compatible thread form when closing these entries.
Entries marked M20 are M20 x 1.5 thread form. On devices with multiple conduit entries, all entries will have the same thread form.
When installing in a hazardous location, use only appropriately listed or Ex certified plugs, glands, or adapters in cable/conduit entries.
WARNING
Physical access
Unauthorized personnel may potentially cause significant damage to and/or misconfiguration of end users’ equipment. This could be intentional or unintentional and needs to be protected against.
Physical security is an important part of any security program and fundamental in protecting your system. Restrict physical access by unauthorized personnel to protect end users’ assets. This is true for all systems used within the facility.

3.5  Trim the transmitter

Devices are calibrated by the factory. Once installed, it is recommended to perform a zero trim on gage and differential pressure transmitters to eliminate error due to mounting position or static pressure effects. A zero trim can be performed using either a Field Communicator or configuration buttons.
For instructions using AMS Device Manager, see the Rosemount 3051
Reference Manual.
Note
When performing a zero trim, ensure that the equalization valve is open and all wet legs are filled to the correct level.
Procedure
1. Choose your trim procedure.
• Analog zero trim – Sets the analog output to 4 mA.
2. Also referred to as a “rerange,” it sets the lower range value (LRV) equal to the measured pressure.
3. The display and digital HART output remains unchanged.
• Digital zero trim – Recalibrates the sensor zero.
4. The LRV is unaffected. The pressure value will be zero (on display and HART® output). 4 mA point may not be at zero.
5. This requires that the factory calibrated zero pressure is within a range of 3% of the URV [0 + 3% x URV].
Example: URV = 250 inH2O Applied Zero Pressure = + 0.03 x 250 inH2O = + 7.5 inH2O (compared to factory settings) values outside this range will be rejected by the transmitter.

3.5.1  Trimming with a Field Communicator

Procedure
1. Connect the Field Communicator. See "Connect the wiring and
power up" for instructions.
2. Follow the HART® menu to perform the desired zero trim.
