Note regarding ERROR 30
With bipolar coagulation, it may happen that, over a longer period of time, a short circuit occurs on one of
the bipolar forceps. Particularly for thin forceps, there is a danger with a short circuit that the forceps begin
to glow due to the high current and the HF generator is damaged due to a mismatch.
Since tissue resistance quickly reaches values above 50 ohms during a coagulation process with conventional
bipolar instruments, normally after starting the coagulation by desiccating the tissue, it is assumed that,
with a continuously low resistance of less than 50 ohms, an error status results which is indicated by
ERROR 30.
In addition, there are large-area coagulation forceps for which a resistance less than 50 ohms is set, insofar
as the legs are only open to a small degree. If the operating surgeon activates such an instrument with a
small leg opening, ERROR 30 is indicated after approx. 5 seconds and activation is switched off. This error
message is felt to be a nuisance by some operating surgeons. In these particular cases, the ERROR 30 error
message can be switched off on units above Version 2.00 by means of the jumper in position J8. In this case,
at a resistance less than 50 ohms, the output current of the ICC is limited to 1.5 A.
WARNING
For a power setting greater than 20 W, there is a danger of destroying the HF generator after approx. 1
minute during short-circuit operation. There is no warning if the ERROR 30 error message is switched off.
