If you replace the module in the event of an error, refer to the following chapters:
see "Assembly, removal, and electrical installation" on page
replacing a module" on page
The "LED" column specifies which local diagnostics LED indicates the error.
For every error that occurs, first remove the cause of the error. If necessary, ac-
knowledge the error. The "Acknowledgment/remedy" column specifies whether an
error must be acknowledged and which special conditions apply for re-enabling an
input or the module.
WARNING
With the exception of a few special cases, the acknowledgment of an error can re-
sult in a hazardous state as well as unintentional machine startup since the safe
output is immediately returned to the operating state.
• Before acknowledging an error you must make sure that the 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.
WARNING
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.
