Example: You are responsible for planning and implementing the startup behavior and the
restart behavior according to your risk analysis. To prevent an unexpected startup, a reset
button may be required to generate a manual reset signal at the machine. This will depend
on both the results of the risk analysis and the signal path.
Additional safe control devices, such as three-position enable switches, etc., may be
required.
2.3 System startup and restart behavior
Startup "Startup" refers to the behavior of the PSR-TRISAFE-S safety module after switching on (or
applying the supply voltage) and following configuration via USB interface or
IFS-CONFSTICK.
Unless a startup inhibit is configured, the safety module starts up immediately following
successful configuration (i.e., after pressing the "Confirm" button). The signal inputs are
then evaluated and the outputs controlled accordingly.
Restart "Restart" refers to the behavior of the safety module after the safety function is triggered and
following a return to normal operation, for example, after unlocking the emergency stop
control device, which means safe operation is possible again.
With an active startup/restart inhibit, the corresponding (inhibited) safe module output
remains in the safe state. This prevents an undesired startup/restart of a machine controlled
by the relevant output terminal block.
Reset button To enable the function of the machine, which is controlled by the PSR-TRISAFE-S output
affected by the active startup inhibit/restart inhibit, the inhibit must be removed by a reset
signal.
As in the case of the stop category (see page 2-4), the startup and restart behavior of the
safety module depends on a specific output, and how this output is connected in the
configured safety logic.
The reset signal is used at the same time to exit the error state once the error cause has
been removed.
Implementation using safe
functional blocks
To implement a startup inhibit/restart inhibit, safe functional blocks must be used in the
SAFECONF configuration software, which have the relevant parameters for activating the
startup inhibit and/or restart inhibit.
The safe state of an output terminal block is power off mode (signal value: FALSE).
