Biopsy unit
Biopsy unit not responding
•
Check power switch on biopsy controller.
•
No contact during start-up. Retry.
•
Check cables.
•
Check biopsy controller, fuses and power.
•
Check LEDs V1-V5 on the D200 board
- V1, TxD error -> Replace the D200 board according to Replacement of components in
the biopsy controller on Page 6 - 5.
- V2, NVM error -> Initialize the BC nvram according to Initialization of BC nvram on the
D200 board on Page 9 - 2.
- V3, ADC error -> Replace the D200 board according to Replacement of components in
the biopsy controller on Page 6 - 5.
- V4, PROM error -> Replace the EPROM according to Replacement of components in
the biopsy controller on Page 6 - 5.
- V5, RAM error -> Replace the D200 board according to Replacement of components in
the biopsy controller on Page 6 - 5.
•
If LED V2 (NVM error) and error message "Biopsy unit not responding" appear after
replacement of D200, follow the procedure described in Initialization of BC nvram on the
D200 board on Page 9 - 2.
•
Recalibrate biopsy unit.
•
If "Biopsy unit not responding" occurs after calibration, proceed with retry.
Problem with calibration
•
Check that you have all targets in the image, use 0.7 magnification.
•
Check that you use the right needle length.
•
Check that you have set the same target both on the biopsy unit and in the workstation.
Initialization of BC nvram on the D200 board
Background: In ASW a unit test of the Mammomat, Biopsy Controller and Camera is per-
formed when entering Stereo Calibration. (Stereo calibration is blocked if any of the unit
tests fails.) However, if the D200 board in the BC is replaced with a new board, this new
board will have an empty nvram, i.e. no checksum will be present in the nvram. This will
be reported as an error by the unit test, and stereo calibration (which updates the check-
sum) will be blocked.
Proceed as below to perform a "dummy calibration", that will update the checksum.
NOTICE
Opdimar
Service
The system MUST NOT be used with this "dummy calibration"!
Calibrate with "Biopsy Calibration" directly when the system is
up.
