4. Black Beam Block Only - Tube Detect LED Alignment.
a. Loosen set screw holding beam block (
).
b. Set volt meter to DC volts and c) probe to TP6 [CE MARK] or TP22 [NON-CE
MARK] and (-) probe to GND.
c. Adjust Beam Block.
[CE MARK]
Rotate beam block clockwise until voltage reads less than +0.25V and then rotate
counter-clockwise until voltage reads +0.6V to +0.7V. If this voltage cannot be set, then a
Beam Block replacement may be necessary.
[NON-CE MARK]
Rotate beam block clockwise until voltage reads less than +1.0V and then rotate
counter-clockwise until voltage reads +2.5V to +2.8V. If this voltage cannot be set, then a
Beam Block replacement may be necessary.
d. Tighten but DO NOT over tighten set screw.
e. Verify that Beam Block Collar does not impede tube or mixing paddle motion.
f.
