If the "CAL brAc" error message appears, the internal braking system
of the XT20 may need to be adjusted. The intelligent transport software
is capable of calibrating the XT20's brakes automatically in a self-test
procedure. This procedure may be performed as a regular maintenance
procedure every 250 hours of head drum operation (to see the hours on
your unit, hold SET LOCATE and press FAST FORWARD).
1.
Obtain a standard ST-126 length tape (preferably a Quantegy
489 such as the one shipped with your unit) that has already been
completely formatted from beginning to end. Use a non-essential tape
(i.e., don't insert your only copy of a master tape). Do not use other
lengths of tape such as ST-180 or ST-60.
2.
Turn off the POWER switch. Hold REWIND and FAST
FORWARD while turning the power back on again. The display will
read "CALIbrAt".
3.
Insert the tape into the transport.
4.
At this time the unit will adjust the brake tension
automatically. The transport will shuttle back and forth for about 5
minutes. During the operation, the tape will half-eject twice. This is
normal.
5.
The display should briefly read "PaSS" before ejecting the
tape fully and returning to the "ADAT-XT" start-up screen. The brakes
have now been recalibrated.
If the "CAL brAc" message appears again shortly after a brake
calibration has been performed, there may be something wrong with
the tape being used. Check operation with another tape. If the
message persists, the unit must be professionally serviced.
Note: If these errors occur only with a certain tape, or display once in a
while, it's probably not cause for concern. Errors 1 through 3 and 9 can
indicate conditions that may damage a tape; the other errors won't
damage the tape or the machine. Backup the data from that tape to
another machine, if possible, and continue working from the backup
copy.
