stops with motor power off, there is either an optical sensor problem or electrical noise on the col-
limator control board.
In either of these cases above, change the Collimator Set (see Job Card D/R A280 - Collimator Set
on page 1369 ).
3. If the error persists during normal operation and not during system boot, check the error log to see
whether there is another collimator blade error.
• If there is another collimator error then refer to the diagnostics for that error to resolve the prob-
lem.
• If there is no other collimator error then this error is due to the Gantry CPU sending a command to
the collimator before the collimator could acknowledge previous command. In this case the faulty
FRU is the Gantry CPU, which you must change (see
Job Card D/R A190 - Gantry CPU Board on
page 1131 ).
FRUs:
2-43 JC DIAG A1405 COLL FILTER NOT READY
Diagnostic for:
141/005 error code (CAN code is 0x5200)
1. Check the cable connections (motor drive cable W501, optical sensor cable W505, motor cable
W507 or W509).
2. Reboot the system. If the error persists, dismount the collimator box to be able to see the Filter
Wheel.
3. If there is no interference within the spectral filter itself reboot the system and check the filter wheel
movement:
a. If the wheel turns in one way and does not change direction before the stop, the cause is linked
to an optical sensor failure or collimator control board problem.
b. If the wheel does not move at all or the gear cannot be released by hand then either the wheel
has failed or there is failure in motor drive cable or control board.
c. If the wheel turns and changes directions for up to seven steps (normally it is three steps) and
stops with motor power off, there is either an optical sensor problem or electrical noise on the col-
limator control board.
In either of these cases above, change the Collimator Set (see Job Card D/R A280 - Collimator Set
on page 1369 ).
4. Turn the Filter Wheel manually - if there is mechanical interference the cause of the error is a
mechanical assembly problem. Check whether the Filter Wheel interferes with the tube tilt plate
screw, and if it does then reassemble the spectral filter and tilt plate. If there is interference within the
spectral filter itself or the shutter is broken, change the Filter Wheel (see
Job Card D/R A285 - Colli-
mator Filter Wheel Assembly on page 1375 ).
5. If the error persists during normal operation and not during system boot, check the error log to see
whether there is another collimator filter error.
• If there is another collimator error then refer to the diagnostics for that error to resolve the prob-
lem.
• If there is no other collimator error then this error is due to the Gantry CPU sending a command to
the collimator before the collimator could acknowledge previous command. In this case the faulty
