5.2.15 Device status screen
The
device status
screen shows the status of device components. The
status information is saved with every data set. Observe the device status to
be able to detect tendencies and properly plan maintenance.
Depending on the communication profile used, status data may be output via
the interface. This is the case e.g. with the communication profile “Bayern-
Hessen.”
If a value exceeds the specified limit, the device changes to “
check de-
vice status
” mode. In this case the source of the problem has to be
found and remedied. The table below contains various explanations.

Explanation
sensor flow
The measured
data is invalid.
flow in between
indicates the current flow rate. The set-
point is
4.8 l/min
. The flow rate is standardized to
standard
atmospheric temperature and pressure (SATP)
, i.e. based on
25°C and 1013 hPa.
If the actual value deviates more than 5% from the setpoint,
the measured data is invalid. An error indication appears.
flow velocity in between
shows the detection volume,
which is the amount of air that is tested.
An error is indicated if the particle velocity deviates more than
15% from the setpoint.
The setpoint is the value

The measured
data is invalid.
Detection of more than one particle in the optical detection
