AND
+15V (TP1, TP2).
a) short the R33 resistor (board 801260-801260/a). This prevents activation of the RF power generator, thus
preventing possible damage to electronic circuits that have not been tested yet.

C) MICROCONTROLLER (board 801261-801262)
ESTING ONCE EQUIPMENT IS TURNED ON
1) T
When the electrosurgical unit is turned on, the microcontroller does automatically a selftest (about 15 seconds) to
verify anomalies of working (if present). If everything is all right, you’ll have in sequence:
- lighting of 5 green LEDs of working mode;
- lighting of power display;
- lighting of timer display (only in MB1/A-MC model);
- lighting of red LED (neutral plate alarm), yellow LED (CUT/BLEND activation) and blue LED (FORCED
COAG/SOFT COAG/BIPOLAR activation) with short acoustic signals.
After the selftest procedure, the unit shows what version of the software is being used (with a short acoustic
signal) and the display pertaining to output power shows the number '0'.
After turning on the unit, during the selftest or any other condition, the system controls and prevents possible
abnormalities shutting down output power and displaying error type with its specific code:

I) CHECKING RF CURRENT LEAKAGE
High frequency current leakage, for insulated equipment, must never exceed 150mA RMS, as required by the CEI
EN 60601-2-2 REGULATIONS (IEC 601-2-2). The microprocessor for the electrosurgical unit MB1/A-MC has
controls allowing it to keep well below such limit. To test the efficiency of these controls, it is indispensable to
duplicate the most extreme test conditions, which in the case of the electrosurgical unit MB1/A-MC are obtained
with the CUT, BLEND, FORCED COAG and SOFT COAG at their highest power setting.
The average figures for leakage current are 110mA.
Measurement must be made as indicated by the CEI EN 60601-2-2 REGULATIONS (with insulated equipment).
