ConMed 7550 - Error Storage and Retrieval; Error Display Configuration

B-7
No RF Output. No RF Drive on the Power FETs. If true for both amps, then:
-HVDC < 12V
-Check for 15V on T1 & T2 of the
amplifiers.
-PP relay (not the problem if bipolar or
ABC have no RF output).
If only one amp, then:
-Spray relays if only Spray (K2, K4)
-FILR relay if Cut, Blend, Pinpoint and
Bipolar (K1, K3)
-PP relay if Cut, Blend, Pinpoint and
Spray (K8)
-ABC relay if only ABC (K9)
-Bipolar relay(s) if only Bipolar
(K10,11)
If only a handcontrol or footcontrol,
then the relay associated with that RF
output.
Error Storage and Retrieval
The last 16 activation errors are saved automati-
cally. Power On Self Test, idle, and test mode
errors are not stored. Activation errors are saved
in a circular buffer that writes over the oldest
error and saves the new error. If multiple error
codes occur and are displayed during use of the
unit, they are stored in the sequence that they are
displayed.
• Unit must be in test mode to activate error
display.
• Press “Store” switch to display errors or to exit
error display.
• First error to be displayed will be the newest.
BIPOLAR POWER DISPLAY will show 1.
• Use PROGRAM SELECT SWITCHES to
display the other errors.
• Press “Monitor Set” switch to clear error
memory.
Error Display Configuration
BIPOLAR POWER DISPLAY -Error number, 1 is the newest and 16 the oldest.
ABC POWER DISPLAY -Last active mode power setting.
GAS FLOW DISPLAY -Flow setting.
BLEND DISPLAY -Blend setting.
PROGRAM DISPLAY -Program setting.
MONOPOLAR CUT/BLEND POWER DISPLAY -Toggle between “Err” and the error code.
MONOPOLAR COAG POWER DISPLAY -Toggle between Active status and Mode LED status.
Mode LED status is displayed when the MONOPOLAR CUT/BLEND POWER DISPLAY shows “Err”.
Note: the Active status and Mode LED status codes are in decimal and must be translated to binary. The
individual bit field description can be obtained from lists shown below. D0 is the least significant bit and D7
is the most the least significant bit.
Active status
D0 =1 when “Return Fault” LED on
D1 =1 when FLOW FAULT ALARM LED on
D2 =1 when LOW GAS SUPPLY LED on
D3 =1 when Remote Power Control Mode active
