7.6 SIGNALING OF EXCESSIVE TIME OF DELIVERY (OVT) (OVT)
If the operator exceeds the maximum time of disbursement, recommended by the international norms, that is 10 seconds, the
equipment produces a signal of warning consisting of a bright intermittent signal OVT. If despite the signal of warning the
operator insists in the continuous delivering, after a time depending from the type of current, and from the level of the same
one, the signal of warning is transformed in impediment to the delivering of current that is signaled through the signal OVT
constantly illuminated. The interdiction lasting of the current delivery continues for 30 seconds and then the warning light
OVT is extinguished.
7.7 SIGNALING OF EXCESSIVE IMPEDANCE IN THE CIRCUIT OF NEUTRAL ELECTRODE
(OC)
For the meaning of this warning signal please refer to the previous description of the neutral electrode circuit.
The warning light OC lightening if the circuit is open, it is extinguished by closing the plate and there is a respect for
parameters selected and, in phase of delivery it’s with an acoustic signal.
7.8 PRESETTABLE SETTING BY USER
The equipment allows to the user to change the following settings: the level of the acoustic signal for the delivery (between
min and max), power regulation
To modify the level of the acoustic signal for the delivery it must use the regulator ‘speaker volume’ placed on the back panel,
setting a level between min and max.
To modify the power level press the keys + e – of the CUT e COAG section. The power step will be unitary for power values
between 0W and 50W, it will be 10 for power values higher than 50W.
7.9 AUTOMATIC CONTROL OF THE INTERNAL PARAMETERS
The unit has an automatic control system of some of the internal parameters. When it switched on, the unit makes a control on
the monopolar and bipolar logics, indicates, on the seven segments display, respectively by
Check A.
e
Check B.
The positive
result of the control is signaled on the display LCD of the PROGRAM section, by ‘Check Monopolar OK’ and ‘Check Bipolar
OK’. If the result is negative, the presence of errors will be marked by
Err xxx,
and the description of the event-error will be
visualized on the LCD display.See Guide to the Problems’ Solution for further information.
7.10 CONNECTORS
Patient plate connector
This is the point of connection for the neutral electrode to apply on the patient.
Remember that the neutral electrode can be disposable and reusable.
Handle connector for the monopolar1 cut and coagulation
This is the point of connection for the handle with double push-buttons to realize
the functions of the cut CUT and coagulation COAG1.
Remember that the handle without push-buttons must be connected to the ‘active’
connector.
