A-25
Unable to position device within specified tolerance [E_TOLERANCE_I] Comment: For the stepping motors, the aperture shuttle or the TZ drive, indicates that
the requested position could not be obtained within the specified device tolerance.
Action: For the TZ drive (table pedestals), check the firmware version. If it is not 2.30
or higher, replace the TZ EPROM with the latest version. If the problem persists (or if
the firmware version was already 2.30 or higher), it may be caused by a thermal
overload in the DC motors. Our experience has been that they cannot run at much
more than a 5% duty cycle. You can check whether it is a firmware or hardware
problem by engaging the emergency stop button on the operator's panel. Then use the
table up switch to move the table. If it does not move, wait at least twenty (20) minutes
and try again. If it moves after 20 minutes, it was a thermal overload. If it does not
move, call Hologic Field Service.
Action: For one of the stepping motors (AR, AY, TX or TY), either the motor has not
been properly calibrated, the motor is binding, or the drive belt is too loose.
Action: For the aperture shuttle (LOCUS CARM), either the apertures have not been
calibrated or the mechanism is binding. Visually inspect the aperture shuttle and use
the MOVE_REL command to verity that the shuttle is moving without binding. If it
does not move or binds, fix the electrical or mechanical problem with the shuttle. If it
does move, recalibrate the shuttle.

The system was unable to restore one or more scans.
Action: This usually means that the hard drive is full. Check the "Room for ..."
message in the status window. If the disk is not full, then this indicates a hard drive
problem.
