Troubleshooting
Data transfer from the controller to the data logger is not working.
1.
Ensure that the data logger is connected to the controller via the DL-bus or the CAN
bus.
2.
Check the connections and in particular ensure the polarity is correct.
3.
With the UVR1611, data output must be activated if logging over the data link (DL-bus)
is to take place (output 14 defined as "
data link
").
4.
Ensure that, the data logger is configured for the corresponding data logging process
(DL-bus or CAN bus)
5.
If several controllers are recorded using the data logger, check the data connections
individually to limit the problem. To do this, connect the data link (DL-bus) or CAN bus
as appropriate to the other controllers. When doing so it is important that the data link
is connected directly to the controller and not to the data input of the data logger, as
otherwise you will not receive useful results!
5.1.
If data transfer functions over the DL-bus with each controller individually, then
the cause of the error is crosstalk between the two data links of the DL-bus. In
this case the two data links must be routed separately or at least one data link
must be routed in a shielded cable.
5.2.
If data transfer via the CAN bus functions with each controller individually, the
cause of the fault may be the allocation of 2 identical network node numbers or an
incorrect network terminating resistor.
6.
To limit the cause of the error during data transfer to a single data link, carry this out
as a test over a short cable (< 1 metre).
6.1.
If data transfer functions over the short cable, then the error cause could be
crosstalk caused by an external interference source in the data link (DL-bus). In
this case, the data link must be routed in another way or a shielded cable must be
used.
7.
If, in spite of the testing of all listed points, incorrect behaviour still exists, please con-
tact your dealer or contact the manufacturer directly. However the cause of the fault
can only be found if a
precise description of the fault
is provided!
