Novus e 4. Troubleshooting
Service manual 75
Connect a DMM to TP12 (kVref) and TP17 (GND) on
L1800 and take an exposure.
Then connect the DMM to TP11 (mAref) and TP17
(GND) and take another exposure.
The values for the reference signals can be counted
as described in chapter 3.6 L1800, Generator Board -
Test points
If the reference values are correct, but feed back val-
ues are not, the Tubehead and/or the L1800 Generator
board may be faulty and must be replaced.
If there are no reference signals check the cabling be-
tween the L1800 Generator board and L1700. Replace
if faulty.
Error E10 (CCD initialization/confi guration failure)
CAUSE
There is no serial bus connection or the CCD sensor
could not confi gure itself.
SOLUTION
Check the condition of all the cables and connectors to/
from the CCD sensor as well as the cables from CPU
to L1700 and cables between L1700 and L1500. Check
that none of the fuses on L1500 have blown.
Check that CCD fi lter board is mounted correctly and
cables are properly connected. If the problem still
exists, replace sensor.
Error E11 (CCD power failure)
CAUSE
Supply voltages to the CCD sensor were not within tol-
erances during imaging.
SOLUTION
Check the condition of all the cables and connectors to/
from the CCD sensor.
Check the voltages on L1500 by checking the refer-
ence LEDs. Always measure the voltages from the test
points. Note that the voltages are only enabled during
an exposure. To enable the CCD voltages without tak-
ing an exposure, connect a jumper to J23. Remove the
the jumper after taking measurements.
