Maintenance Manual
General description
The ESG-100 electrosurgical unit enables the user to perform common monopolar
and bipolar applications. Both can be operated in cutting and coagulation modes. The
electrosurgical unit is equipped with a user friendly display that allows the user to
select from a list of optimized modes. All settings are saved automatically and are at
the user’s disposition when switching on the electrosurgical unit the next time or when
the user changes the modes during a procedure.
The electrosurgical unit is equipped with a high voltage power supply which allows fast
control of the output resulting in safely controlled tissue effects and protection against
over- and under-dosage. In addition, the integrated high power cut support (HPCS) is
a precondition for optimized cutting procedures without initial delay.
Another feature of the electrosurgical unit is the fast spark monitor (FSM). This
technology measures the spark intensity in intervals of a few milliseconds when
cutting tissue. The fast spark monitor ensures the application of output powers that are
as low as possible and as much as necessary to achieve well defined tissue effects.
Moreover, the contact quality monitor (CQM) analyses continuously the contact
resistance of the neutral electrode, ensuring a safe application and minimizing the risk
of thermal injuries to the patient. The contact quality monitor status is continuously
displayed by visual indicators.
Finally, the leakage protection sensor (LPS) automatically monitors the high frequency
leakage current through the patient and produces a visual and acoustic signal if the
current is too high.

The footswitch middle pedal (34) may have three different functions:
1)
If the peristaltic pump unit is connected and switched on, the footswitch middle
pedal (34) activates the pump flow.
2)
If there is no communication of the electrosurgical unit with the pump, the user
has the possibility to choose between two functionalities:
2a) The user toggles between the modes as it is done by the toggle button (7) at the
front panel (see fig. 4.1). The change will be indicated by a beep tone. This is the
default setting.
Example: A bipolar coagulation mode is preset (e.g. SoftCoag). By pressing the
footswitch middle pedal (34) the user toggles between the bipolar modes (e.g.
RFCoag -> RFCoag + RCAP -> SoftCoag).
2b) The user changes either between monopolar cut and monopolar coagulation or
between bipolar cut and bipolar coagulation mode without using one of the select
buttons (1, 2, 3, 4) at the front panel (see fig. 4.2). The change will be indicated
by a beep tone.
Example: A monopolar cut mode is preset (e.g. Cut 1). By pressing the footswitch
middle pedal (34) the user changes to a monopolar coagulation mode (e.g.
ForcedCoag 1). The last used coagulation mode will be called.
To use the function 2b), change the footswitch function in the service menu as
