T .14 Mini-Playfield Test
AWARNING
Keep hands away
from mini-playfield
Movement of the mini-playfield can cause SERIOUS PHYSICAL INJURY.
Keep fingers and loose clothing away from
ALL
moving parts.
As a
safety feature,
during normal game play (and attract mode) the
mini-playfield will not move unless the coin door is closed and the playfield
glass is on. During the mini-playfield test, both flipper buttons must be
pressed before it will move.
When this test is first started a warning message will appear. Pressing the "ENTER" button again
confirms that the operator is aware that the high torque motor can cause physical injury. During the test,
the operator must press and hold both flipper buttons to allow the mini-playfield to move.
The Dot Matrix display (left side) shows a front view of the Mini-playfield.
The top line (right side)
identifies the eleven sub-tests. The second line indicates the current test mode. The third line shows
the "number of faults" or errors (from the feature audits).
Note, pressing the credit button during this
test will clear the fault number (for easier detection of intermittent problems when cycled overnight).
And the fourth line is a status line, showing the current "moving", "kicking", "flashing", or "error" state.
When a switch is considered "active", its area is filled in. A switch is active when it is "closed". An opto is
the opposite and is active when the beam is broken, making the switch "open". If all opto switches are
abnormally "active" or "open" look for a loss of power, switch column, and opto common wires (for the
emitters and receivers).
NOTE:
If the switch matrix has a shorted row or column (the entire row or column is "ON") the
entire switch matrix (from the switch tests) is temporarily displayed instead of the mini-
playfield. Locate the offending row or column and fix this problem FIRST.
NOTE:
If there are 2 errors with the last 2 complete test cycles, the mode will automatically set
itself to "STOPPED" mode. This should prevent any accidental damage to the device.
This test is similar in function to the coil test. The different sub-tests can be selected by the
"+"
or "-"
buttons. There are 3 modes to this test (controlled by the ENTER button).
