Operation and Maintenance
Proof Test and Inspection
The following proof tests are recommended. Proof test results and corrective actions taken
must be documented at
www.emersonprocess.com/rosemount/safety/certtechdocumentation.htm in the event that
an error is found in the safety functionality.
Use "Table 1: Field Communicator Fast Key Sequence" to perform a Loop Test, Analog
Output Trim, or Sensor Trim. See the 2051 reference manual (00809-0100-4101) for
additional information.
Proof Test
This proof test will detect 99% of DU failures not detected by the 2051
automatic diagnostics.
1. Conduct a Loop Test. On HART host/communicator enter the Fast Key
Sequence 1, 2, 2.
a. Enter the milliampere value representing a high alarm state
b. Check the reference meter to verify the mA output corresponds to the entered value.
c. Enter the milliampere value representing a low alarm state
d. Check the reference meter to verify the mA output corresponds to the entered value.
2. Perform a minimum two point sensor calibration check using the 4-20mA range points
as the calibration points.
a. If necessary, use one of the “Trim” procedures available in the 2051 reference manual
to calibrate.
NOTE
The user determines the proof-test requirements for impulse piping.
Visual Inspection
Not required.
Special Tools
Not required
Product Repair
All failures detected by the transmitter diagnostics or by the proof-test must be reported.
Feedback can be submitted electronically at
www.emersonprocess.com/rosemount/safety/certtechdocumentation.htm.
The 2051 is repairable by major component replacement. Follow the instructions in the 2051
reference manual (document number 00809-0100-4101) for additional information.
Reference
Specifications
