WARNING: Hazardous machine state/unintentional machine startup
With the exception of a few special cases, the acknowledgment of an error can result in a hazardous
state as well as unintentional machine startup since the safe input is immediately returned to the
operating state.
●Before acknowledging an error you must make sure that acknowledgment will not cause the machine
to switch to a hazardous state.
●When planning the machine or system, make sure that acknowledgment is only possible if the
danger zone is visible.
WARNIG: Unintentional machine startup
Startup /restart following power up and when there is no longer a demand of the safety function can
result in unintentional machine startup.
●Please note that:
●The module starts up once the configuration and parameterization data record has been
downloaded successfully and internal testing has been completed without errors.
●A safety-related input is automatically reset to "1" when the safety function trigger is reset.
●If you do not want the machine to restart automatically, configure the safety logic accordingly.
