4.4.3 Remote control error codes
If the remote control for the 750 Autosampler is switched on via the
RS232 interface then each error will produce a corresponding error
code. For each of the errors listed below information is provided as to
whether the error can be remedied (R) or if it is a fatal system error (F).
The Autosampler remains ready for operation with R-errors and the op-
erator can enter a new command. With F-errors it is no longer possible
to use the Autosampler. The instrument must be switched off and re-
paired (see chap. 4.4.2).
