•
To replace the damping resistor, remove the two screws that secure the top
and bottom of the resistor to the heat sink. Position the new damping resistor
on the heat sink and reinstall the screws.
•
To replace the power MOSFET (under the small circuit board), remove the
four screws that secure the small circuit board to the heat sink. Set the board
and screws aside for reinstallation.
Note the orientation of the notch on the power MOSFET. Then, remove the 2
screws that secure the power MOSFET. Position the new power MOSFET on
the heat sink and reinstall the two screws.
Position the small circuit board over the power MOSFET and reinstall the four
screws that secure the board to the heat sink.
Install the Right Heat Sink
1.
Position the right heat sink above the right side of the chassis and slide the
heat sink component leads into the matching sockets on the Power Supply/RF
board.
2.
Through the holes on the outside of the chassis, install the two screws that
secure the heat sink to the Power Supply/RF board.
3.
Install the two screws that secure the heat sink to the chassis.
4.
Connect the right heat sink resistor cable to J12 on the Power Supply/RF
board.
5.
Install the Control board.
a.
Position the Control board over the Power Supply/RF board, fitting the
edge of the board into the slot on the right heat sink. Slide the board down,
carefully fitting the edge connector into the matching connector on the
Power Supply/RF board.
b.
Place the retention bracket on the left rear heat sink and install the screw
that secures the bracket to the heat sink.
c.
Connect the Display board ribbon cable to the Control board and lock the
connector.
6.
Position the cover above the chassis and slide it down. Tighten the four screws
that secure the cover to the chassis.
Notice
Calibrate the generator after you install a new heatsink or replace components on
the heat sink. Component differences may affect output waveforms. Refer to
Calibrating the Force EZ-C Series Electrosurgical Generator
in Section 6 for
instructions.
