display. Roll a ball around either of the loops (a ball may be ejected from the trough by
pressing the launch button). A sound is made as the ball passes over the loop switches,
and the state of the loop switches is updated in the display. If the ball is traveling around
the loop from left to right, the right control gate should open upon activation of the second
left loop switch (L.HI). If the ball is traveling around the loop from right to left, the left
control gate should open upon activation of the second right loop switch (R.HI). When
the ball has finished its path around the loop (either from left to right, or from right to left),
the test should report "TEST PASSED - PRESS ENTER" on the bottom line of the
display. Any other result indicates a problem with either the loop switches, or the control
gates, or both. To re-test, press the Enter button.
"Left Gate Stuck Closed" errors can be cleared in "Loops Mode" by repeatedly testing the
right loop (the Enter button must be pressed at the end of each test). The test will clear
the error when there have been two consecutive successful right loop tests in this mode.
"Right Gate Stuck Closed" errors can be cleared in "Loops Mode" by repeatedly testing
the left loop (the Enter button must be pressed at the end of each test). The test will
clear the error when there have been two consecutive successful left loop tests in this
mode.
Jets Mode: This mode is used to verify that the ball is able to pass into either of the
loops and be diverted into the jets. This is useful for clearing "Left Gate Stuck Open" and
"Right Gate Stuck Open" errors that may appear in the test report. If an error exists, one
of them will be shown on the bottom line of the display.
To verify loop switch and control gate operation in "Jets Mode", press the Up or Down
buttons until the message "Test Mode: To Jet Bumpers" appears on the second line of
the display. Roll a ball into either of the loops (a ball may be ejected from the trough by
pressing the launch button). A sound is made as the ball passes over the loop switches,
and the state of the loop switches is updated in the display. If the ball is traveling to the
jets from left to right, the right control gate should remain closed upon activation of either
of the left loop switches (L.LO and L.HI). If the ball is traveling to the jets from right to
left, the left control gate should remain closed upon activation of either of the right loop
switches (R.LO and R.HI). When the ball has finished its path into the jets (either from
the left, or from the right), and makes contact with one of the top lane switches, the test
should report "TEST PASSED - PRESS ENTER" on the bottom line of the display. Any
other result indicates a problem with either the loop switches, or the control gates, or
both. To re-test, press the Enter button.
"Left Gate Stuck Open" errors can be cleared in "Jets Mode" by repeatedly testing the
right loop (the Enter button must be pressed at the end of each test). The test will clear
the error when there have been two consecutive successful right loop tests in this mode.
"Right Gate Stuck Open" errors can be cleared in "Jets Mode" by repeatedly testing the
left loop (the Enter button must be pressed at the end of each test). The test will clear
the error when there have been two consecutive successful left loop tests in this mode.
Ball delivery from the shooter lane can be verified by this test in either "Loops Mode" or
"Jets Mode" by placing a ball into the shooter lane, and pressing the launch button.
When in "Loops Mode", the ball should travel all the way around the loop, and be
delivered cleanly to the left flipper. When in "Jets Mode", the ball should be delivered into
the loop, through one of the top lane switches, and into the jet bumpers.
During this test, the diagnostic test buttons inside the coin door act as follows:
Escape: This button returns to the previous menu.
Down/Up: These buttons toggle the test mode between "Loops Mode" and "Jets Mode".
Enter: This button is used to clear the "TEST PASSEDITEST FAILED" messages.
