• Ensure the switch is in the correct position
for the frequency for which the system
will be placed in service.
• Replace the card cage cover.
2. Mains Voltage:

former. In the center of the terminal
block are shorting plugs and on the front
of the terminal block are numbers to
identify each position. A system config
-
ured for 120V or 100V will have five (5)
shorting plugs. A system configured for
210-240V system will have only three (3)
shorting plugs. The shorting plug loca

tions are:
• 120V & 100V: 1-2, 2-3, 4-5, 6-7, 7-8
• 210-240V (Rated range 198V to 260V):
1-2, 5-6, 7-8
NOTE: The terminal block configuration is
shown on the interconnect diagram (Figure C-2).
• Close the cover and secure with the two
screws located on both sides.
7.7 Initial Setup & Test
Performing this procedure will verify functional
operation of the CONMED 7550 Electrosurgical
Generator + ABC™. A system error detected on
“power up” will be displayed as an error code.
(See error codes in Troubleshooting, Appendix B)
The testing of this section does not test or verify
system calibration, but only if the unit is func
-
tioning from a user perspective. The calibration
section provides procedures for full system testing
and calibration.
Figure 7.1 is a listing of test leads that are needed
to test the System 7550™. To test the output
power during the functional testing, the test leads
are necessary. However, if the output power is
not tested, then only the accessories are necessary.
7.7.1 Accessory Connections
1. Connect a handcontrol accessory to the
Monopolar Handcontrol Jack (Handcontrol
1).
2. To test the ABC™ mode with a handcontrol
switched accessory, it must be connected
to the Beam/Monopolar Handcontrol
Jack (Handcontrol 2). A Triple Option
Handcontrol Accessory connected to
Handcontrol 2 will allow activation of Cut,
Coag, & ABC modes. Fasten the connector
of the ABC™ accessory to the Argon Beam
Coagulator connector.
3. Connect a Patient Plate adapter from the
Dispersive Electrode receptacle to an ESU
analyzer.
4. Set the electrosurgical analyzer load for 500
ohms to test all modes except bipolar. Bipolar
load should be 100 ohms.
Note: To test bipolar output power, use test leads.
Connect the test leads to the two bipolar RF out
-
put jacks of the ESU and the other end to the 100
ohm load. To activate bipolar, use a footswitch if
available, and if not, use a third test lead to short
out the right RF output receptacle to the bipolar
hand sensing receptacle located just above the RF
output receptacles.
5. Connect all three footswitches (Monopolar,
ABC™, & Bipolar) to the footswitch recep
-
tacles located on the Mobile Storage Pedestal
(Cart).
6. Connect a tank of argon gas. Ensure the tank
is securely fastened to the cart with the tank
strap. Once the tank connector is securely
fastened to the tank, turn the tank valve fully
counter-clockwise and verify the argon tank
has at least 200 psi for test purposes.
7. Insert a Footcontrol adaptor into the
Footcontrol jack. When testing output power
using an ESU analyzer, it is recommended
to use a test lead from the Footcontrol jack
to the ESU analyzer, and use footswitches to
activate the system.
7.7.2 Display Panel Testing
1. Connect the power cord to a grounded AC
outlet and press the main switch/breaker to
turn the system on.
2. Verify during system initialization that:
• Displays “88” on
ones and tens digits.
• Displays “3” on all
hundreds digits.
• All
mode indicators illuminate.
• An audible tone of variable frequency
occurs.
• An error code (Err) is not displayed in the
cut window (See Err in Troubleshooting
if displayed).
