Troubleshooting
Errors may arise
• on the plug connections
• on the ultrasonic transducer
• on the probes
• on the Ultrasonic generator:
The device is robustly constructed and designed for a high level of reliability. Nevertheless,
the possibility of a malfunction due to a defective component can never be fully discounted.
Mechanical defects of the HF connector sockets, the plug connectors, the ultrasonic transducer,
etc., are possible as a result of frequent use or even incorrect handling, e.g. by dropping them.
Critical faults are recognised by the device and signalled by a red LED and an intermittent signal
tone (3 times), and displayed with an error number, see next page.
Error no.
Possible cause
Remedial action
002
Frequency setting not possible
Perform frequency scan. If the error occurs again,
contact BANDELIN.
003
No power output, amplitude
setting not possible
Error correction should only be carried out by
BANDELIN. Send in the complete ultrasonic
homogeniser.
004
Mains voltage fallen short of
Check mains connection, check fuse

ciently tight
- Check for damage:
• Horn/probe contact surfaces
• Horn/probe
threads
• Probe radiation surface
If needed, replace the USC/probe and then check its
function. Use the “probe check” or “scan frequency”
functions for this purpose. After successfully completing
the frequency scan, do not restart operation until
initialization is complete. In the event of failure, contact
BANDELIN.

Allow the ultrasonic homogeniser to cool down for at
least 10 minutes, if necessary use a temperature sensor
to check that the operating temperature of the GM has
dropped to < 50 °C.
Note
• If it was possible to remedy the error, the display indicator should be deleted by turning o

and on again.
