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: HART Fast Key Sequence" to perform a Loop Test, Analog Output Trim, or Sensor Trim. See the 3051S reference manual for additional information.
Proof Test 1
Conducting an analog output Loop Test satisfies the proof test requirements and will detect more than 52% of DU failures not detected by the 3051S_C or 3051S_L automatic diagnostics, and more than 62% of DU failures not detected by the 3051S_T automatic diagnostics.
Required tools: HART host/communicator and mA meter.
1.On HART host/communicator enter the Fast Key Sequence 1, 2, 2.
2.Select “4 Other.”
3.Enter the milliampere value representing a high alarm state.
4.Check the reference meter to verify the mA output corresponds to the entered value.
5.Enter the milliampere value representing a low alarm state.
6.Check the reference meter to verify the mA output corresponds to the entered value.
7.Document the test results per your requirements.
