PROCEDURES

SWITCH
TESTS (Continued).
Column
Problems.
If display of two
(or more) switch
numbers
in a column
occurs (while
only
one
switch is actuated),
check for a
short circuit
between the
row wires.
Use
AUTO-UP to
proceed
to
the
next
test.
2.
Switch Edges.
From the
Switch Levels
Test, press
ADVANCE. Observe
that 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
Syslem-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
PiN-BOT switch
prob-
lem
reporting displays
(either at
game
Turn-On or at
the
beginning ol
the Diagnostic
Tests) to
determine
whether the
switch can be
actuated.
It the
switch’s
name and
number are
displayed
while the
operator checks
its operation,
the
operator then
knows
that ihe
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.
