Control board Slot J3 The resetting of the first monoflop IC16 triggers a secondary pulse in the second monoflop IC16 which represents the true actuation pulse for the output stage driver. The length of this actuation pulse is adjustable using the trim potentiometer TP14. The power module generator is therefore always only initiated at the start of a half oscillation through the actuation pulse.

Control board Slot J3 is no longer switched through for actuation of the QK output stage, but instead the output signal of the comparator IC9, PIN 12. This comparator detects the zero crossings of the high frequency current of the QK output stage and provides a pulse at the rate of the HF at the priority encoder which switches this rate through to the actuation with sufficient current flow of the output stage.

Control board Slot J3 sparking which occurs during the cutting and coagulation process at the active electrode. Both control principles have concrete applications. The control of spark intensity can be activated via the “HIGH CUT” key. On the Senso-board, the DC voltage U_FUNKE occurring during a spark is gathered via an isolation amplifier (description there) and directed to the control-board.

Control board Slot J3 stage is addressed. The output signals A and B thus serve in the selection of currently active transistors. From the previously doubled frequency, the short start and stop pulses are produced for the respectively active transistor. The first part of the monoflop IC17 produces the start pulse, the second part the stop pulse.

QC power stage Slot J4 This charge cannot then flow back into the actuation circuit after the actuation pulse has ended, since diode D8 acts as a block and diode D9 also permits no reverse current due to its Z-diode characteristic. The result is that the transistor remains in a conducting state as long as its GS capacitance has sufficient charge.

QC power stage Slot J4 in time. For this possibility, in which the logic might operate undefined, a "Power-on time-delay circuit" avoids undefined starting of the output stage transistor. With transistor T11, the supply voltage VDD = + 15 V is monitored. If this voltage is missing, capacitor C10 is quickly discharged via diode D12.

Power module Slot J5 Power module UL Slot J5 Driver and output stage of the HF generator The actuation signal for the HF output stage is generated on the control board (IC16) and fed to the power module driver IC1 via the motherboard. Due to the high-gate source capacitance of the output stage transistors T1 and T2, the driver must be able to emit and accept high reactive currents when transferring this capacitance.

Senso-board Slot J7 Phase monitor for the patient circuit The phase monitor determines the phase angle between the voltage and current in a high-frequency patient circuit. In this way not only the apparent power, but also the active power emitted to the patient can be calculated.

It is therefore also necessary to check the symmetrical current distribution on both halves of the electrode. The NESSY system, a neutral electrode safety system patented by ERBE, takes care of all the tasks mentioned.

Senso-board Slot J7 The symmetry of HF current on the halves of the neutral electrode is measured by a symmetrical transformer, the output voltage of which is a function of current symmetry. Implementation: The circuitry is found on the Senso-board. The oscillator is designed as a frequency- selective feedback amplifier: The amplifier IC6 actuates the push-pull stage, consisting of the transistors T4 and T5, and passes the amplified output signal to the frequency-selective serial circuit made of capacitor C20, coil L1 and the inductivity from the primary side of transformer UE4.

Relay board Slot J8 (for ICC 300, 350) Since a diode is switched in series for each of the two pushbuttons on the handle, although both diodes have a definite and opposite polarity, this circuitry can be detected exactly via the dampened half-wave after pressing a pushbutton, as to whether and which button was activated.

The 8-fold D-flipflops IC2, IC3 and IC12 are used as target memories for columns (IC2) and rows (IC3). The columns of the lamp matrix LS1 to LS6 are activated via the driver transistors T2, T20, T11, T10, T4 and T9 switched as emitter followers in a multiplex method and each switched for a brief time to +5 volts.

Upper wiring module The “upper wiring module” PCB directs the rectified supply voltage from the motherboard via the plug J14 as a supply voltage to the QC power stage. In addition, this PCB is used as a connection between the QC power stage and the power module, since currents of this dimension cannot be directed via the motherboard.
