8 Troubleshooting

The following chapter describes how to resume operation of the instrument in the event of any minor
problem. It will list some possible occurrences, their probable cause and suggests how to remedy the
problem. The troubleshooting table below lists possible malfunctions and errors of the instrument and
describes operator enabled courses of action to correct some of tubing problems by him or herself.
The appropriate course of action is listed in the column “Corrective measure”.
The elimination of more complicated malfunctions or errors is usually performed by a BUCHI technical
engineer who has access to the official service manuals. In this case, please refer to your local BUCHI
customer service agent.
In the event of an error, the pump will stop and an acoustic alarm will sound. The acoustic alarm can
be stopped by pressing the START or STOP button once. If the error has been eliminated, the alarm
can be stopped by pressing the START or STOP button twice.
The beeping noise will not sound if the system has been externally stopped by the Fraction Collector
C-660 or the TTL input.
The Pump Module C-610 shows the error message on the display in the form “Exy” whereby “xy”
stands for the error number.
Error “01” of the pump module can either be confirmed with the START or the STOP button. When
the START button is pressed, the error message display disappears, and the pump restarts with the
current value. If the STOP button is pressed, the error message display disappears, and the current
value is shown, as usual. If the flow rate has still not been achieved, error “01” will be displayed again.
If the waste container is full or the connected Fraction Collector C-660 shows an error, the pump
will stop without displaying an error. The error message will be displayed on the fraction collector.
The pump cannot be switched on again until the cause has been eliminated and the error has been
confirmed at the fraction collector.
