Site acceptance
After the installation and configuration, proper operation of the transmitter
should be verified. A site acceptance test is therefore recommended. The proof
test outlined in this section can be used for this.
Operation and maintenance
The Rosemount 5300 Series Prior-Use option must be tested at regular intervals
to confirm that the overfill and empty tank protection function result in the
desired system response. The following proof test is recommended. If an error is
found in the safety functionality, the measuring system must be switched out of
service and the process held in a safe state by means of other measures.
Proof test results and corrective actions taken must be documented at
www.emersonprocess.com/rosemount/safety.
The required proof test intervals depend on the transmitter configuration and
process environment. Refer to the reference manual and the Failure Modes,
Effects, and Diagnostic Analysis (FMEDA) report for further information.
Proof test
This test detects approximately 95% of the possible Dangerous Undetected (DU)
failures of the transmitter including the sensor element, not detected by the
transmitter’s automatic diagnostics. See the Rosemount 5300 Reference Manual
(Document No. 00809-0100-4530) for additional details and instructions. Prior to
this test, the echo curve should be inspected to ensure that no disturbing echoes
affecting the measurement performance are present in the tank.
Required tools: Field Communicator and mA meter.
1. Bypass the logic solver or take other appropriate actions to avoid false trip.
2. Disable write protection if the function is enabled.
3. Using Loop Test, enter the mA value representing a high alarm current output.
Verify that the analog current reaches that value using the reference meter.
This step tests for compliance voltage problems, such as a low loop power supply
voltage or increased wiring resistance.
NOTE:
Use the Handheld HART Communicator: Fast Key Sequence [2, 4, 1, 4] to perform a Loop
Test. See the Rosemount 5300 Series Reference Manual (Document No. 00809-0100-4530)
for additional information.
4. Using Loop Test, enter the mA value representing a low alarm current output.
Verify that the analog current reaches that value using the reference meter.
This step tests for possible quiescent current related failures.
5. Perform a two-point calibration check of the transmitter by applying level to
two points on the probe within the measuring range
1
. Verify that the current
output corresponds to the level input values using a known reference
measurement.
This step verifies that the analog output is correct in the operating range and that
the Primary Variable is properly configured.
1) For best performance, use the 4 - 20 mA range points as calibration points.
