Evaluation of results - Part 2: Testing of current output 1
The amount of deviation between the measured current and the set point must not exceed the
measured error specified for the safety function. The deviation should not exceed ±1 % /
±300 µA.
‣
Note data relating to measured error→ 18.
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
At least 99 % of dangerous, undetected failures are detected using these test sequences
(PTC = 0.99). The influence of systematic errors on the safety function is not fully
covered by the test. Systematic faults can be caused, for example, by medium properties,
operating conditions, build-up or corrosion.
‣
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.
