the source tray away from the enclosure.
4 Using a properly connected grounding hook, touch the source tray and the frame
of the vacuum enclosure in several places to neutralize any residual high-voltage
charge.
5 Make sure the MAN/AUTO switch on the control unit’s front panel is set to MAN.
6 Use the thumbwheel on the control unit’s front panel to select pocket 1
7 Switch on the indexer, if it is not already on. After going through some rotation
involved in its initialization routine, the indexer will rotate the hearth to the factory-
set home position for pocket 1.
8 If pocket 1 is not correctly centered within the cutout in the top of the source,
switch off the indexer.
9 Turn the hearth by hand until pocket 1 is precisely centered within the cutout.
10 Using the end of a paper clip or some other small-diameter probe, push in the
spring-loaded phase adjustment pushbutton and keep it depressed as you switch
on the indexer and as the hearth goes through its initialization routine. (This
routine involves what may appear to be random rotation.) Release the
pushbutton only after the hearth has returned to the new home position for
pocket 1 and stopped. If this is not the correct home position, switch off the
indexer and repeat steps 9 and 10.
11 Use the pocket selection thumbwheel to change pockets several times, checking
to see that each pocket goes to the correct home position. If the hearth does not
remain properly in phase, return to pocket 1 and repeat steps 9 - 11.

STEP NO. PROCEDURE
1 Make sure the MAN/AUTO switch on the control unit’s front panel is set to MAN.
2 Use the thumbwheel on the control unit’s front panel to select pocket 1.
3 Switch on the indexer, if it is not already on. After going through some rotation
involved in its initialization routine, the indexer will rotate the hearth to the factory-
set home position for pocket 1.
4 If pocket 1 is not correctly centered within the cutout in the top of the source,
switch off the indexer.
5 Switch the indexer on and off rapidly, watching the hearth move a small amount
each time you do so. When pocket 1 is centered in the cutout, leave the indexer
switched off.
6 Using the end of a paper clip or some other small-diameter probe, push in the
spring-loaded phase adjustment pushbutton and keep it depressed as you switch
on the indexer and as the hearth goes through its initialization routine. (This
routine involves what may appear to be random rotation.) Release the
pushbutton only after the hearth has returned to the new home position for
pocket 1 and stopped. If this is not the correct home position, switch off the
indexer and repeat steps 5 and 6.
7 Use the pocket selection thumbwheel to change pockets several times, checking
to see that each pocket goes to the correct home position. If the hearth does not
remain properly in phase, return to pocket 1 and repeat steps 5-7.
