6.2.1 Error-free state (CONTROL)
During operation, the green LED light indicates that the HF unit is delivering the set
output.
Slight
fl
ickering of the indicator occurs with changes in the load, but does not signify
an error unless a red LED is
fl
ashing or
fl
ickering at the same time.
6.2.2 Excessive temperature (TEMPERATURE)
The HF units are cooled with air. A fan on the rear of the housing provides
the necessary air
fl
ow. In the case of unacceptably high cooling element temperatures
(e.g. possible at ambient temperatures above 45°C or in cases of impeded air
fl
ow),
the entire system does not switch off. Instead:
An automatic reduction of the output in accordance with the cooling element
temperature creates a working state in which the HF unit continues to work safely with
a reduced output, allowing work to continue. Once the excessive temperature has been
resolved, the set output is automatically restored.
The "TEMPERATURE" LED lights up in the case of excessive temperature.
In the case of excessive temperature, an error signal is emitted at the remote control
connection on the rear of the generator (see chapter 2.2.3).
6.2.3 Incorrect adjustment (TRANSDUCER)
If the HF voltage or HF current of the connected ultrasonic transducer has too high
a value as a result of an impermissible load (e.g. a totally cavitated / used transducer,
an incorrect transducer type or impermissible models from other manufacturers),
an automatic output limitation is enforced.
An incorrect adjustment is indicated by the "TRANSDUCER" LED.
During the error state, an error signal is emitted at the remote control connection
on the rear of the generator (see chapter 2.2.3).
