Operation and Maintenance
Proof Test and Inspection
The following proof tests are recommended. Proof test results
and corrective actions taken must be documented at
http://rosemount.d1asia.ph/rosemount/safety/ReportAFailure_newweb.asp in the event that an
error is found in the safety functionality.
Use the fast key sequences in Table 1 on page 15 or Table 2 on page 16 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: Field Communicator and mA meter.
1. On the Field Communicator, enter the Fast Key Sequence for Loop Test.
2. At the “Choose Analog Output” prompt, select “Other” to manually input a value.
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.
Proof Test 2
This proof test, when combined with the Proof Test 1, will detect over 92% of DU failures not
detected by the 3051S_C or 3051S_L automatic diagnostics, and over 95% of DU failures not
detected by the 3051S_T automatic diagnostics.
Required tools: Field Communicator and pressure calibration equipment.
1. Perform a minimum two point sensor calibration check using the 4-20 mA range points as the
calibration points.
2. Check the reference mA meter to verify the mA output corresponds to the pressure input
value.
3. If necessary, use one of the “Trim” procedures available in the 3051S reference manual to
calibrate.
4. Document the test results per your requirements.
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
http://rosemount.d1asia.ph/rosemount/safety/ReportAFailure_newweb.asp.
The 3051S is repairable by major component replacement. Follow the instructions in the 3051S
reference manual (document number 00809-0100-4801) for additional information.
