Troubleshooting
General faults
General faults are subdivided into warnings and errors. Current measured values con‐
tinue being output when there are warnings; measurement is no longer possible when
there are errors.
Possible faults and rectification measures are described in the table below. In the
case of faults that cannot be rectified using the information below, please contact the
manufacturer. See the back page for your agency.
Warnings and errors are described in a status word which is shown on the device
display and is output via the RS-422 interface in the upper half (byte 3 and byte
2) of a double word coded in hexadecimals. The status bits can also be output via
the PROFIBUS DP interface (Module 5 - Status/2w), or via the Ethernet interface, see
Telegram Listing Dx1000 (English, part number 8021820).
The lower half of the double word (byte 1 and byte 0) contains, among other things,
the status of the digital outputs, the activity indication of the measuring laser and the
alignment laser as well as other functions. The entire status double word is shown in
.
