Return to the second page of the service mode and review the error history list as follows:
Turn the Generator off. Access page one of the service mode by holding in the Increase and Decrease
buttons at power up. Press the Standby Button to access page two. CRC 55947 should now be displayed
followed by the line rate and error history.
The numbers in the far right of the display, separated by a "/", indicate the number and type of errors. Press the
Decrease Button to scroll through the last ten errors. An explanation of the error types follows:
Error No.
Description
1-6
Not used and should never appear.
7
The check sum stored in memory does not agree with the calculated value.
This would be caused by an unreliable microprocessor PCB. See section
6.3.8 to replace the microprocessor.
8
The frequency control circuit on the generator PCB is not oscillating. See section 6.3.2
to check for a blown fuse. If all the fuses are intact, see section 6.3.6 to replace the
generator PCB.
9
A higher than normal voltage was detected on the output of the switching power supply
circuitry located on the generator PCB. This may be caused by either electrical interference
from other devices in the O.R. or by a faulty generator PCB. Verify that the Generator is not
within one foot of any other equipment (especially electrosurgical devices). If the problem
persists, replace the generator PCB (see section 6.3.6).
10
The cabling leading from the generator PCB to the keyboard became disconnected or
is intermittent.
11
The microprocessor PCB is unable to match the selected line rate with the actual frequency
of the line voltage. Verify that the Generator is configured for the appropriate line rate (see
section 4.3). If the problem persists, there is typically significant noise on the AC source.
NOTE: Whenever error numbers 7, 8, 9, or 11 are added to the error history, a SYSTEM ERROR
is displayed.
NOTE: The error history is erased whenever the validation sequence is entered from this second page of
the service mode. The validation sequence is described in section 4.3.
If a problem with the ULTRACISION System is still unidentified after performing the steps listed above, continue
the diagnosis with the Extended Functional Test.
If a problem exists with the system and resolution cannot be obtained through the Trouble Shooting Guide (section
5.1) and the Diagnostic Service Mode (section 5.2), proceed with the following steps to be performed at power up.
Again, it is important to read all of Chapter 6, which details disassembly, test equipment, and warnings, prior to
performing detailed diagnosis of any internal module.
CAUTION: During this testing, the instrument blade will become active. Do not touch the blade!
1.
Turn the Generator on as described in steps 1 through 8 in section 3.2.
2.
If not already at Level 1, press the Decrease Button until LEVEL 1 is displayed.
