Error state

ATTENTION: Property damage through immediate shutdown
The device ensures stop category 1 only in error free operation. If the supply voltage is lost
or in the case of an internal error, the device behaves acc. to stop category 0.
Do not use the device in applications in which stop category 1 must be maintained even
•
in case of failure.
WARNING: Loss of the safe state in the error state
While in the error state, no module-internal tests run and, due to an accumulation of errors,
the safe state may be exited.
If the module takes on a faulty state, examine, acknowledge or rectify the error within 72
