The maintenance condition of the selected sensor is switched
off. Linked outputs are released.
6 Call up the measured value display with <M>.
The display of the sensor in the measured value display does
not flash.
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 after the
maintenance condition has been switched off only (see
section 4.9.3).
