a) Footswich : CUT/COAG. Pedals.
b) Pencil swich : Cut/COAG. Button
Appropriate LED’s turn on with respective command input. a) and b) may be simultaneously connected to the machine and any one can issue command audio tone, to identify the CUT / COAG. command.
Interlocks: Simultaneous issue of foot switch or pedal switch (or CUT from Footswitch and COAG. from Pencil switch) will cancel the commands, resulting in no audio tone, command LED and no power output. This is a safety feature.
If Alarm LED is ON, (i,e. patient lead fault), then monopolar commands from Monopolar Footswitch / Handswitch are disregraded, i. e. CUT / COAG. LED’s cannot turn on. However a dual audio tone only is issued on any monopolar command. No surgical power output can occur.
a) Footswitch (single pedal) Command can be issued from Bipolar Footswitch if the panel indicator is FS in the bipolar block. Issue of the command is indicated by LED as well as an audio tone.
Precedence and Interlocks: Bipolar has precedence over monopolar that means if bipolar & monopolar are issued simultaneously, then bipolar is executed disregarding monopolar.
PPF (Patient Plate Fault). disconnection of one or both leads of patient plate circuit will turn on ALARM LED. In this case, any monopolar command will produce 2 tone audio, no command LED, no issue of monopolar command & no monopolar power. Bipolar block remains unaffected and is functional in spite of ALARM LED ON as it is not related to patient plate of monopolar generator.
