C. Relay Numbering
Figure 6-2. Locations—Relay Board and Relays
201, 202, etc. Each block consists of two columns of nine
holes, defining the left edge and right edge of the blocks.
The bottom of the block is defined by two groupsof three
holes each (Figure 6-2, view B). The number within the
block is the same for each block. This enables each hole to
be specified if necessary. In Figure 6-2, view B, the hole
1O1F4 has a + besideit.
Relays are placed on pins that are secured to the board.
When more than onerelay is in a block, the relay may be
designated by U or A (upper), and L or B (lower). The is
the top relay, the one closest to the connector tabs. An
example is 101U and 101L as shown in Figure 6-2, view C.
There will be one space betweentherelays.

D. Component Numbering
Componentsare located between the two columnswithin
a block or between blocks (Figure 6-2, view D). The
column rows are numbered from top to bottom within a
block. A component within a block is designated by block,
component type, and row numbers. A component between
blocks is designated by the from-block, component, row,
from-pin, and to-pin.
6.2.1 Reed Relays
As shown in Figure 6-2, view C, the reed-relay points and
coil connections are numbered. Therelay is always placed
on the card so that the pick coil is at the top and the
