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 and Run modes.
Repeat: The Repeat mode pulses a single flipper. Press the Enter button to begin the
test. Press the Up or Down buttons to cycle through the flipper coils one at a time. To
return to the Test menu, press the Escape button. To advance to the next test mode,
press the Enter button.
Stop: The Stop mode halts the Flipper Coil test. No coils should pulse while the test is
stopped. To return to the Test menu, press the Escape button. To advance to the next
test mode, press the Enter button.
Run: The Run mode cycles through the flippers automatically. The display shows the
name and number of the flipper coil currently being pulsed. To return to the Test menu,
press the Escape button. To return to the Repeat mode, press the Enter button.
T.13 ORDERED LAMPS 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 buttons to cycle through
the lamps. Lamps light in a clock-wise or counter clock-wise direction starting from the bottom of
the playfield. The 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
indicate the system has detected a problem. To return to the Test menu, press the Escape
button.
T.14 LAMP ROW-COL.
This test allows individual rows and columns in the lamp matrix to be operated. This is useful for
troubleshooting wiring and driver problems.
Press the Up and Down buttons to cycles through the different rows and columns.
