ERR. MEMORY
Checksum error: Check the datum, 80
operating parameters and compen-
sation values for non-linear axis error
compensation. If this error recurs,
contact your service agency!
1) These errors are important for the attached device. The
error signal (pin 19) at the D-sub connection EXT is active.
2) Active with P84: ERROR ON
The ND sends the error message to the BCD output on
the first and second decades. All other decades receive the
ASCII character “A“ (1010).
Other Error Displays
If “OVERFLOW” appears, the measured value is too large or
too small:
ä Set a new datum.
or
ä Traverse back.
If all sorting signals light up, the upper sorting limit is
smaller than the lower limit:
ä Change operating parameters P18 and/or P19.
To clear error messages:
Once you have removed the cause of the error:
ä Clear the error message with the CL key.
