12 Troubleshooting
12.1 General faults, warnings, and errors
General faults are subdivided into warnings and errors. Current measured values as
well as respective warning messages continue to be output when there are warnings.
Measurement is no longer possible when there are faults and measured value 0 and
the respective error value are therefore output. If there is an error, the device continues
to extrapolate measured values no later than when the error suppression time set in
ErrRej expires. During this time, the WrnPlb plausibility warning is output. If measurement
is still not possible after the error suppression time expires, measured value 0 and the
associated error message are output.
Warnings and errors are signaled via the PWR LED and can be read in the main menu
as long they are active. Warnings and errors can also be output via the multi-functional
outputs or the fieldbus interface via the SOPAS ET configuration software. They are not
stored on the device. NoWrn or NoErr is displayed in the main menu during fault-free
operation.
The PWR LED signals the device status.
NOTE
Possible faults and corrective actions are described in the tables below for trouble‐
shooting. In the case of faults that cannot be rectified using the description below,
please contact the manufacturer. See the back page for relevant contact details.
