The frequency scan is completed once fi ne-tuning has been successful, and the display
switches back to stand-by mode.
Otherwise, an error message such as Error 012 appears again.
6.3 Troubleshooting
Errors may arise
• on the plug connections
• on the ultrasonic converter
• on the probes
• on the ultrasound 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 connection for the ultrasonic converter, the plug connectors, the
ultrasonic converter, 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
Converter:
No USC No ultrasonic converter (UW) connected
to the ultrasound generator (GM) Connect the UW to the horn/probe on the GM.
The GM should then automatically recognise
which UW has been plugged in.
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
010 Frequency synchronisation
malfunctioning, frequency display is
currently not possible - Check whether the probe has been mounted
correctly = su ffi ciently tight
- Check for damage:
• Horn/probe contact surfaces
• Horn/probe
threads
• Probe radiation surface
If needed, replace the UW/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 initialisation is complete. In the event
of failure, contact BANDELIN.
011 No return signal from UW, UW or probe
defective
012 Error in frequency scan, no resonance
frequency found, probe defective
014 Permissible internal operating
temperature exceeded, ultrasonic
homogeniser switches o
ff
Allow the ultrasonic homogeniser to cool down
for at least 10 minutes, if necessary check with
a temperature sensor that the operating temperature
of the GM has dropped to < 50 °C.
