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.

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.
