1 These errors are important for the connected encoder. The error
signal at pin 19 of connection X41 is active.
Error X1/X2: Encoder signal too large
The encoder signal at input X1 or X2 is too large (e. g, when the encoder is
mounted incorrectly). Use the diagnostic functions of the ND 287 to check the
encoder. 1
Interface commands too fast Two commands for measured value output are sent in too close a succession.
Violation of control limits
A sample has violated the upper or lower control limit during analysis. Check the
respective control chart and change the process settings, if required. When this
error occurs, error pin 19 is not activated, but the ND automatically switches to the
control chart that caused the error.
Error message Error cause and corrective action
If all sorting and tolerance checking symbols light up,
the upper sorting limit for the currently selected part is
smaller than the lower sorting limit. Change the respective
parameters in the SELECT PART or TOLERANCES form.
