4.1 Error Messages
An error occurring during a sample series is displayed by a blink-
ing red LED. The number of flashes indicates the error number.
This must be acknowledged with any 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:
1* RAM defect Call Metrohm-Service.
3* battery low The battery for the permanent storage of user meth-
ods must be replaced.
4* manual stop The Sample Changer has been stopped manually.
No acknowledgement needed.
6* changer low power The power supply cannot deliver enough power for
the simultaneous operation of all components cur-
rently in use (stirrer, pumps, lifts).
7* rack data missing No sample rack is in position or no rack data can be
found for the sample rack that is in place.
8* invalid rack code The rack code read by the changer could not be
found in the internal position tables.
