4.8.3 Switching off the maintenance condition
Note
If a power failure occurs, the outputs automatically are in the non-
operative condition (relays: open, current output: 0 A; see component
operating manual of the output module). After the end of the power
failure the outputs work as defined by the user again.
If a power failure occurs while an IQ sensor that is linked with an output
is in the maintenance condition, the current and relay outputs work as
defined by the user only after the maintenance condition has been
switched off (see section 4.8.3).
