Troubleshooting
Errors may arise
• on the plug connections
• on the ultrasonic converter
• 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.
Once detected by the device, signi
fi
cant errors are signalled using a red LED and an intermittent
signal tone (3 times), and displayed with an error number – see the following table.
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
Insu
ffi
cient mains voltage
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.
020
Unknown command (communication
error), remote control command was not
executed or ignored
Observe the application information “Protocol and
command set for remote operation” and check
commands.
021
Incorrect command length
(communication error), remote control
command was not executed or ignored
022
Unknown type (e.g. probe)
Check the sieve, UW, standard/booster horn,
and probe for compatibility.
