2.3. Acceptance Test of Safety Functions
The acceptance test must provoke that all of the limit values which have been set for the enabled
safety functions are exceeded in order to prove/confirm a correct function.
Indicate if the Test Execution is done at the first machine of this machine type or within
series production.
The test execution in series production is not saving any test part. Even in series
production the same adequate care has to be assured.
Try to force safe DI dual check safety alarms as above via software logic or hardware failure
simulation (preferred).
Safe DO alarm situation cannot be simulated easily. Only in case of programmable safe
I/O application, output signals are built by PMC and can be tested by forcing corresponding
signal. If there is no safe I/O application, please delete above row “Monitoring DO signal NG”
