User intervention is not required in the normal operation of PWD22/52.

When the sensor is installed, the user may need to change some of the
default settings. Section Initial Settings on page 43 describes the initial
setup in greater detail. The settings and corresponding commands are

The standard output messages contain a status character, which presents
the results of the internal diagnostics to the host computer or the user. If
the sensor indicates a warning or an alarm in a standard output message,
the host computer or the user can obtain a detailed status report with a
special STA command. The status report can also be polled (message 3)
in place of the standard data message. Usually, the detailed status
information is sufficient for locating the fault.
