2. Switch Edges.
From the Switch Levels Test, press ADVANCE. Observe Ihat the player 1 and 2 displays show the
message, SWITCH EDGES, the Credit display shows 06 (Switch Edges Test identifier), and the BALL IN
PLAY/MATCH display is blank, indicating that no switch is actuated.
This test permits the operator to test whether actuating a switch provides the proper signal to the Sys-
tem-11 switch testing program. When actuating a switch, the operator should see the switch's name and
number (in the player 1 and 2, and the BALL IN PLAY/MATCH displays, respectively). If no indication
appears at the time the switch is actuated, the operator then knows that there is a malfunction associated
with that switch.
Using this technique, the operator can test each switch appearing in the
GRAND LIZARD
switch problem
reporting displays (either at game Turn-On or at the beginning of the Diagnostic Tests) to determine
whether the switch can be actuated. if the switch's name and number are displayed while the operator
checks its operation, the operator then knows that the reported problem with that switch is NOT currently
caused by a switch malfunction. The operator can then seek other causes for the reported problem,
being almost certain now that the switch did not fail.
This test
is
also useful when the operator is adjusting
the sensitivity of
a
particular switch's actuation mechanism.
