Reassembly
6. Gently slide the encoder head down until the mount-
ing screw holes in the press support base appear in
the head's mounting slots.
7. Center the screw holes in the mounting slots. Secure
the encoder head with the two pan-screws but do not
tighten them yet.
Alignment
The purpose of this alignment is to set the internal refer-
ence mark for the encoder. This reference mark resets
the distance register in the generator after each thruster
cycle and ensures repeatable distance measurements from
cycle to cycle.
1. Check the position of the encoder scale's mounting
hole slots using the 6" ruler. Measure the distance
from the center of the screw to the edge of the slot
in both directions. When the screws are centered
horizontally, carefully tighten the screws.
2. Measure a vertical distance of 1.375 inches (34.92
mm) up from the bottom edge of the encoder scale,
as shown in Figure 6-8.
3. Adjust the bottom edge of the encoder head to align
to this distance and tighten the screws on the encoder
head.
4. Push in the ABORT button (on the press base).
Turn on the generator, and set it to measure dis-
tance.
5. Set the air pressure to the desired level.
6. Perform the following procedure to test the encoder
for the proper setting:
• Pull out the ABORT button (on the press
base). Allow the thruster to return to top of
stroke.
• If the encoder position reads -0.06" to 0.30",
then the encoder is set correctly.
• Secure the two screws. Proceed to Step 7.
