TESTIDIAGNOSTIC PROCEDU RES (Continued)
SWITCH TESTS.
1. Switch Levels.
(From Solenoid Test) To initiate the Switch Levels Test, press ADVANCE,
Observe that the
upper
display shows the message, SWITCH LEVELS, and the lower display shows 06 (Switch
Levels Test Identifier).
Normally,
the
right portion of the lower display remains blank, indicating
that no switch is actuated.
If,
however, a switch
is
actuated (possibly stuck closed). the lower display shows that switch's
number. while the upper displays indicate the switch's name. A sound also accompanies the
displays. (This is another facet of the
1P@[bD©[;!
~@OO©§
System-11 B's switch testing capability.)
" more than one switch is closed. a series of displays show each actuated switch's name and
number.
(In addition, either of these problems could result
in
the reporting of a switch problem (or
problems) at game Tum-On or at, the beginning of Diagnostic Tests.}
As soon as the operator opens. a closed switch, its name and number are eliminated from the
Switch Levels display series. For
~11.0©~ iF@OO©I!i,
switch numbers can range from
01
through
64 . Refer to the Swltch~Matrlx Table for switch numbers and wiring information.
CPU Board
connections at jacks 1J8 (columns) and
1
J1 0 (rows) are also listed in the table.
