Endress+Hauser Proline Promag 300 - Test Sequence F (PTC = 0 %)

Proline Promag 300 HART Proof testing
Endress+Hauser 41
7.4.2 Test sequence: Heartbeat Verification
1. Select Heartbeat Verification (standard).
2. Initiate Heartbeat Verification.
3. Verification is performed automatically in the device: see the "Standard verification"
section of the "Special Documentation for Heartbeat Technology" .
Acceptance criteria: External Heartbeat Verification
1. Check whether the result of the verification is Passed or Failed.
 The check is completed successfully if the result of the Heartbeat Verification is
Passed.
2. To document the test, print the verification report. Device diagnostics or device status as
proof of testing.
The following systematic errors can be detected:
Buildup in the sensor pipes
7.4.3 Test sequence: Inspection and on-site visual check
At the transmitter, check the correct sealing function of all the electronics compartment cover
seals and cable entries.
7.4.4 Connecting the test
1. Re-activate the locked SIL mode →  21.
2. Deactivate bypassing of safety function of process control system.
3. Document results of proof test in accordance with the safety management guidelines
applicable to the system.
NOTICE
With the test sequences described, at least 19 % of the dangerous undetected failures
can be detected (PTC = 0.19). The influence of systematic errors on the safety function is
not fully covered by the test. Systematic errors can be caused, for example, by medium
properties, operating conditions or buildup.
‣
If one of the test criteria from the test sequences described above is not fulfilled, the device
may no longer be used as part of a protective system.
‣
Take measures to reduce systematic errors. For detailed information on the orientation,
medium properties and operating conditions, see the "Operating Instructions" →  10
7.5 Test sequence F (PTC = 0 %)
• Heartbeat Verification
• Inspection and on-site visual check
Detection of additional systematic errors with Heartbeat Verification: influence of the process
on the device (e.g. formation of buildup in the sensor).
