1. Prepare the collimator to be installed by
unscrewing the 4 hexagonal socket
screws until the four tabs are completely
withdrawn form the collimator top
mounting plane, see
Fig. 4 Mounting
Screws.
2. If installing a manual collimator, adjust
the collimator shutters to the fully open
position using both knobs.
3. With the tabs fully retracted, the hexagonal
socket screws of the mounting bracket must
be tightening equally up to the end stroke
with 0.45 Nm torque (at least 7 turns), see
Fig. Mounting Bracket.
4. The 4 tabs of the hexagonal socket screws
overlap on the flange outer ring in the same
manner.
5. The collimator tabs adhere to the flange
outer ring. Depending on the optional flange
purchased, the collimator may rotate or be
fixed (no rotation).
6. Once the collimator is coupled to the flange
in the method described above, verify the
distance between the collimator housing and
the mounting flange is equal in all directions
and the collimator face is parallel to the axis
of the table. Loosen the screws and adjust
as necessary.
7. The collimator should be coupled to the
flange firmly. If the collimator is loose, please repeat the above mounting instructions, and if
issues persist, please contact Ralco.
