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.
