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
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
a.If necessary, use one of the “Trim” procedures available in the 2051 reference manual to calibrate.
