Figure 4-3 Setting the Detent
10 Remove the detent spacing tool.
11 Release air pressure from the bellows assembly (item 37, Figure 1-5 on page
1-8 ).
12 Remove the 0.09375" diameter alignment pin of the 750-254-G2 alignment tool
assembly from the hole.
13 Press the crystal switch button on the handheld controller or the instrument
front panel. The sensor will advance to the next crystal position. Each crystal
should be centered in the aperture. Make certain the detent drops in to engage
each tooth of the ratchet (item 29,
Figure 1-5 on page 1-8 ) on each pulse.
14 Secure the actuator cover (item 22, Figure 1-6 on page 1-9 ) to the carousel
housing weldment (item 14, Figure 1-5 on page 1-8 ) using two #4-40 x 0.187"
long socket head cap screws (items 6 and 7, Figure 1-6 on page 1-9 ).
15 Install the front deposition shield (item 17, Figure 1-5 on page 1-8 ) by first
orienting the pins in the front deposition shield to coincide with the locating
holes in the carousel housing weldment (item 14,
Figure 1-5 on page 1-8 ), then
secure the front deposition shield by tightening the two knurled captive screws.
16 Regulate the air supply to 80-90 PSIG (5.5 bar - 6.2 bar) [550 kPa - 620 kPa]
for operation.
The Crystal12 Sensor is now aligned.
