indexer receives any of the pocket-select codes for pockets 3 through 7, it moves
the banana-shaped pocket to the home position and then begins oscillating the
hearth in such a way that the e-beam sweeps from one end of the “banana” to the
other. Pocket select codes 3-7 determines the speed of the oscillating motion, as
the Table below indicates. When the indexer receives the pocket-select code for
pocket 8, it moves the midpoint of the “banana” to the home position and stops.
Hearths with Full-Circle Evaporant Troughs (Code 2)
If switches 1-3 are set for this type of hearth (code 2), the hearth will rotate continuously
in the direction set via switch 5. The setting of switch 4 has no effect on rotation in this mode.
The switch settings that select code 2 is in this mode, the pocket-select codes for pockets
through 7 determine the hearth’s rotation speed, as indicated in the table below. The pocket-
select code for pocket 8 stops or prevents hearth rotation.
