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.
