Precision Platform 4022 Scanner Scanner Maintenance
9.1. General maintenance tasks
WARNING
:
To perform any maintenance, troubleshooting, or replacement of
components, ensure that power is disabled at the breaker.
9.1.1. External surfaces
•
Clean all external surfaces with approved mill cleaning products,
for example, a damp cloth. A mild detergent is acceptable on the
painted and anodized surfaces.
9.1.2. Beams
The scanner steel beams generally require no maintenance. They are
painted with a polyurethane finish that lasts the life of the scanner. Clean
them with an air hose each time the beam covers are removed.
9.1.3. Maintaining the mechanical expansion joint
The expansion joint bearing located under the distant end support is made
of nylon and does not require any lubricant. If excessive beam distortion is
noticed from the Z-sensor profiles after the scanner is heated, check the ¾"
bolts that mount the scanner to the pedestal at the distant end support.
While the scanner is hot, make sure there is a gap between the bushings
under the mounting bolts and the slots in the base of the support in the
CD direction of the scanner. If there is pressure on the bolts in the CD
direction, the scanner will need to be re-set on the pedestal. Check to make
sure that the expansion joint bearing is assembled correctly, using
Honeywell installation drawings as a reference. Also check that the two
smaller shipping bolts between the ¾" mounting bolts in the bottom of the
end support that hold the expansion joint together during scanner
placement have been removed.
