Fatal error
–
the assembly is in the safe operation
mode.
NOTICE
:
For all operating states except RUN the outputs are passivated, i. e. switched off safely. In rhe
RUN state, the state of the outputs is dependent on the implemented PLC programme.
5.4. Parametrization
Parametrisation is carried out via the programme SafePLC
2
.
To be able to send the data to the assembly, a programme adapter is needed. Before use, the
driver of the programme adapter must be installed for the first time.
The description of parametrisation must be taken from the programme manual.
5.5. Regular functional test
To guarantee the safety of the assemblies, once per year a functional test of the safety functons
must be carried out. For the functional test, once a year the blocks used in the parametrisation
(inputs, outputs, monitoring fnctions) and logic modules must be tested with respect to their
functioning, or rather, with respect to their shutoffg getestet werden.
