Maintenance and repair
6.1
Maintenance
SONOREX ultrasonic baths require no maintenance.
For purposes of regular control, the following functional checks may be carried out.
6.2
Functional checks
Check the LEDs
A test routine can be started for an internal function check:
The ultrasonic bath must be switched off for this. When the Start/ Stop button is kept held down,
the ultrasonic bath is switched on with the ON/OFF button.
All LEDs light up after each other for a 1/3 second. The last set values are then displayed.
The test is then successfully completed.
If there are any deviations, the ultrasonic bath must be sent in for checking/ repairs.
Monitoring the ultrasound
Function can be checked using a standard wattmeter. It is to be inserted between the ultrasonic
bath's mains plug and the socket.
• Fill the oscillating tank with
fl
uid, see Section 4.1.
•
Switch ultrasound on: Next, the value displayed is to be compared with the corresponding value
in the technical data (Section 1.4) (tolerances ± 20%).
Checking the ultrasound effect
For monitoring, we recommend the performance of a foil test (biannually).
A suitable frame for the foil test can be requested from the manufacturer. Customary aluminium foil
is used to conduct the test. Next, a comparison is made with previously-generated foils.
For more detailed information, please see the appendix.
A measurement procedure is described in DIN SPEC 40170:2013-11 (Measurement and
evaluation of cavitation noise).
6.3
Error analysis
SONOREX ultrasonic baths are 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.
The following overview of possible sources of error should serve as an aid for error detection and
elimination.
Ultrasonic bath oscillates weakly, unevenly or noise is too loud:
- Has
fl
uid been properly degassed?
- Is it overloaded with objects to be treated?
- Uneven noises (wobbling)
Treat for 10 min.
Remove a few parts.
No error – slightly adjust the
fi
lling
level of the
fl
uid.
Slight erosion visible on the bottom of the bath?
Natural wear.
Ultrasonic bath OK.
Any malfunctions are to be communicated in writing to the manufacturer.
