Figure 7-2 4022-40 Wire Calender Scanner Head Separation
One feature of the 4022-40 Wire Calender Scanner model is that the upper
and lower heads are attached to the scanner using specially designed
brass breakaway screws. This feature is present in order to allow the
heads to break free from the scanner in order to minimize damage to the
scanner in case of lump collision.
Should the scanner heads require removal for maintenance (this happens
very rarely), the brass breakaway screws need to be removed. Care should
be taken when applying torque to these screws (7 ft-lbs maximum) to
avoid damaging them.
There are microswitches present on the upper and lower head vertical
arms as part of the radiation safety interlock system for head removal.
These switches will become disengaged with the removal of the brass
breakaway screws and separation of the vertical head support arms from
the upper and/or lower carriages.
