T.11 Display Test
This test automatically lights every dot in the Dot Matrix Display. A series of
patterns appear in sequence. Each pattern turns On and Off a section of dots. Every dot on the
display should be turned On and Off during this test.
T.12 Flipper Coil Test
The Flipper Coil Test has three modes: Repeat, Stop, and Run.
Only one flipper should pulse at a time. The system has detected a problem if more than one
flipper pulses, a flipper comes On and stays On, or no flippers pulse during the Repeat or Run
modes.
Repeat
The Repeat Mode pulses a single flipper. After entering this test, coil 01 shows in the
display and the corresponding flipper activates. Press the Up or Down button to cycle
through the flipper coils, one at a time. The same flipper coil pulses until the Up or Down
button is pressed. Either press the Escape button to return to the Test Menu, or press
the Enter button to advance to the next mode.
Stop
The Stop Mode halts the Flipper Coil Test. Press Enter during the Repeat mode and the
Flipper Coil Test stops. No flipper coil should be activated while the test is stopped.
Either press the Escape button to return to the Test Menu, or the Enter button to
advance to the next mode.
Run
The Run Mode cycles through the flippers automatically. The display shows the name
and number of the flipper coil currently being pulsed. Either press the Escape button to
return to the Test Menu, or the Enter button to advance to the next mode.
T.13 Ordered Lamp Test
The number assigned to each lamp indicates the lamp's position in the
matrix. The number on the left indicates the column. The number on the right indicates the row.
Example - Lamp 23 means 2nd column, 3rd row.
This test checks each lamp circuit individually. Press the Up or Down button to cycle through the
lamps. Lamps light in a clock-wise or counter clock-wise direction starting from the bottom of the
playfield. Direction depends on which button, Up or Down, is pressed. For each name and
number that is shown in the display the corresponding lamp should light. Any other results
indicates the system has detected a problem.
T.14 Lamp Row-Col Test
This test allows individual rows and columns in the lamp matrix
to be operated. This is useful for trouble-shooting wiring and driver problems.
Press the UP or DOWN buttons to cycle trough the different rows and columns.
