Safety for starting applications
Consider your machine or system when determining the start conditions:
– Starting the machine or system may only take place when no persons are within the
danger zone.
– Comply with the requirements of EN ISO 13849-1 with respect to manual resetting
functions.
This applies to:
–
Switching on of safe devices.
–
Acknowledgment of device error messages.
–
Acknowledgment of communication errors.
–
Acknowledgment of block error messages in the application.
–
Removing safeguards for safety functions.
Observe your safety logic during programming/configuring:
– The change from a safe state (replacement value = 0) to the operating state can cause
an edge change (zero-one-edge).
– Include measures in your safety logic that prevent this edge from starting or restarting
of the machine/system unexpectedly.
