2. Safety
2.3.14 Information on the determination of safety-relevant parameters
The failure rates of the instruments were determined through the use of statis-
tical 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 safe-
ty function (safety loop) should be initiated, in order to test whether
the safety function of the system is still guaranteed. Function tests
are intended to demonstrate the correct function of the whole
safety-related system, including all instruments (sensor, logic unit,
actuator).
