l
Evaluate the status LED blink code (see "Status LED" on page 58).

Load the device log from the myDatalog4 or the myDatanet server and
use DeviceConfig for the evaluation (see "Evaluating the device log"
on page 137).
l
The rechargeable battery or battery pack capacity is virtually depleted.
Not all or no data is
available on the
server.
l
The connection was interrupted during transmission, which is indicated
by a time-out entry in the connection list (see "myDatanet Server
Manual " 805002). Solution: Initiate a ALOHA transmission or wait for
the next cyclical transfer.
l
The assignment of the device and site is not correct (see "Site" on page
59).
The data at the
universal input is
not plausible.
l

Check whether the universal input configuration matches the sensor
output signal (see "Measurement channels" on page 59).
Alarm state of a
measurement value
was not detected. Increase the record interval (attention: This will increase the required data
volume).
Alarm state was not
transferred
although the data is
present.
l
Check the alarm settings of the measurement channel.
l
The connection was interrupted during transmission, which is indicated
by a time-out entry in the connection list (see "myDatanet Server
