Check operation of Lift Screw Assembly Top Brake
1. Power up the Senographe system.
2. Use the control buttons to move the column up and down. When you stop the movement listen out for
the clamping noise of the Lift Screw Assembly Top Brake claming the Lift Screw Assembly Top
Brake. With normal brake operation, the clamping noise occurs within one second of the stopping of
the column movement.
If you cannot hear the clamping noise, then:
•
Check the W510 cable connection to the J6 connector on the Lift Board.
•
Check that the CPLD firmware on the Lift Board is 10.0.1 or later. To do this, go to the Service
Desktop home page and observe the CPLD entry next to the Lift Board in the list of current firm-
ware versions.
3. If you can hear the clamping noise, then the Lift Screw Assembly Top Brake operation is normal. Re-
install the right hand side Gantry Column Covers (refer to
Job Card PHY A044 - Remove/Reinstall
).
