This is an input signal from the bipolar footswitch sense circuit. This signal is generated
by a colpitts oscillator located on the display board and an isolation transformer located on
the main board. When an activation request is made, the output for this circuit becomes a
logic 1 (3.3 volts) signal.
This is an input signal from the coag monopolar footswitch sense circuit. This signal is
generated by a colpitts oscillator located on the display board and an isolation transformer
located on the main board. When an activation request is made via the coag pedal on the
monopolar footswitch, the output for this circuit becomes a logic 1 (3.3 volts) signal.
This is an input signal from the cut monopolar footswitch sense circuit. This signal is
generated by a colpitts oscillator located on the display board and an isolation transformer
located on the main board. When an activation request is made via the cut pedal on the
monopolar footswitch, the output for this circuit becomes a logic 1 (3.3 volts) signal.
This is an input signal from the coag monopolar hand sense circuit. This signal is
generated by a colpitts oscillator located on the display board and an isolation transformer
located on the main board. When an activation request is made via the coag button on
the monopolar handpiece, the output for this circuit becomes a logic 1 (3.3 volts) signal.
This is an input signal from the cut monopolar hand sense circuit. This signal is
generated by a colpitts oscillator located on the display board and an isolation transformer
located on the main board. When an activation request is made via the cut button on the
monopolar handpiece, the output for this circuit becomes a logic 1 (3.3 volts) signal.
This is an input signal from the bipolar foot contact sense circuit. This signal is generated
by a colpitts oscillator located on the display board and an isolation transformer located on
the main board. When a bipolar footswitch is connected to the rear of the unit, the output
for this circuit becomes a logic 1 (3.3 volts) signal.
