Page 44 Installation
(b)If the power supply is equipped with a key lock, remove it arid keep it in your
pocket while you complete this procedure.
2 Lower the source tray, open the vacuum enclosure’s access doors, and swing
the source tray away from the enclosure.
3 (This step may be skipped if a high-voltage power supply has not been
connected to the vacuum system in which you are installing the SRT-422.)
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.
4 Make sure the MAN/AUTO switch on the control unit’s front panel is set to
MAN.
5 Use the thumbwheel on the control unit’s front panel to select pocket 1.
6 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.
7 If pocket 1 is not correctly centered within the cutout in the top of the source,
switch off the indexer.
8 Turn the hearth by hand until pocket 1 is precisely centered within the cutout.
9 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 8 and 9.
10 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
8-10.
