The ultrasonic generator requires no maintenance.
6.2
Error analysis
The ultrasonic generator 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. If operating faults do occur, please observe the following
information.
Caution !
Repairs must only be performed by authorised, quali
fi
ed personnel!
Unauthorised handling will void the warranty!
All generator functions are controlled by the program.
At the beginning of troubleshooting, the mains switch should be turned off. After approx.
6 seconds it should be turned on again.
• In the process, the LEDs on all the HF units must be monitored. All LEDs on all
the HF units should light up for approx. 1 second immediately after switching on.
• If this is not the case for one or both HF units, the communication of all HF units
when operating with the SPS could be disturbed.
In such a case, the generator must be sent to the manufacturer for inspection.
In addition, it is necessary to check whether the fan is functioning properly.
If these controls are performed without a problem, the operating faults can be checked
using the table on the following page.
Preparation:
- Switch on ACTIVE on all HF units. (LED should light up green.)
