3.6.
Emergency stop
The HF device can be switched off at any time by using the on/off switch
25
as an emergency stop.
3.7.
Monitoring functions
3.7.1.
Self-test
When the HF device is switched on, it runs a self-test that checks the
operating elements, acoustic signal, microprocessor and hardware for
proper operation. If errors occur, see Section Detecting and correcting
faults, page 33.
3.7.2.
Cyclical test during operation
During operation, safety-relevant functions and signals are tested
cyclically. If errors are detected, the HF generator will shut itself off. An
error code will be indicated using the power display. For further
information, see Section Detecting and correcting faults, page 33.

Neutral electrode monitoring
Always use the largest possible electrode when attaching a neutral
electrode.
3.8.1.
General information
BOWA recommends using split neutral electrodes, since only this type of
electrode allows the HF device to detect detachment of the neutral
electrode if this occurs.
Monitoring of the neutral electrode minimizes the risk of burns at the site
where the neutral electrode is attached.
Two types of neutral electrodes can be monitored:
Non-split neutral electrodes
Split neutral electrodes.
The split neutral electrodes are shown on indicator
15
, and the one-
piece neutral electrodes are shown on indicator
14
; see Section Fault
indications for EASY monitoring, page 34.
