2.3.14 Information on the determination of safety-relevant parameters
The failure rates of the instruments were determined through the use of statisti-
cal methods in accordance with IEC 61508 on the basis of a type test for the
DPGS40TA.100-xxS.
The instrument is designed for applications with low or high demand rates.
WARNING!
The maximum operating life of a safety-related system is 5 years,
plus a 1.5 year reserve. Any longer operating life is the responsibility
of the operator.
2.3.15 Instrument-specific safety-related parameters
The safety-related parameters for the operation in safety integrated systems in
accordance with IEC 61508 and IEC 61511 are to be taken from the certificate
V 495.01/15, see appendix 3 of these operating instructions.
The safety-related parameters for the operation in safety integrated systems in
accordance with ISO 13849 are to be taken from the certificate V 495.02/15, see
appendix 3 of these operating instructions.
2.3.16 Decommissioning the instrument
WARNING!
Ensure instruments that have been taken out of service are not
accidentally recommissioned (e.g. through marking the instrument).
After exchanging the instrument, a functional test of the entire
safety function (safety loop) should be initiated, in order to test
whether the safety function of the system is still guaranteed. Func-
tion tests are intended to demonstrate the correct function of the
whole safety-related system, including all instruments (sensor, logic
unit, actuator).
