5.1 Error Messages
When an error occurs the execution of the active command is in-
terrupted and an error message is displayed (display blinks). This
must be acknowledged with the <QUIT> key.
If an error occurs during processing of a sample series, the
changer will then be switched into the 'HOLD' state. After the
cause of the error has been rectified, the sample series can be
continued with the next command in the active sequence by
pressing the <START> key. If the error cannot be eliminated, the
method running can also be halted with <STOP>.
The list of possible error messages and their causes:
* battery low
The battery for the permanent storage of user meth-
ods must be replaced.
* changer low power

rently in use (stirrers, pumps, lifts).
