PROBLEM ANALYSIS MESSAGES
The System 11C game program has a great capability to aid the operator and service personnel: At Game Turn-
on (and also at the beginning of the Test/Diagnostic Procedures) after the game has been operating for an ex-
tended period, the player score displays now may signal with a message, "Press ADVANCE for Report", that
the game program has detected a possible problem with the game.
To obtain details of the problem, open the coin door and press the AUTO-UP/MANUAL-DOWN switch to
MANUAL-DOWN.
Press the ADVANCE button to begin displaying the message(s). The following messages
apply to your
ROLLERGA.MES
game.
Adjust Failure. This message indicates a problem with the setting of Game Adjustments. For example, if the
game operator changes Adjustment Item settings by selecting Yes for AD 70 (Install Factory) and then closes
the coin door before the appearance of the FACTORY SETTING message, the game will display the ADJUST
FAILURE message to indicate that the resetting of the Adjustment Items did not occur proper1y. As mentioned
earlier in the Game Adjustment Procedure text (near Ad 70), other factors can also cause this message to
appear.
Check Switch
##.
This message indicates that at least one switch was stuck 'On' at game turn-on or has NOT
been actuated during ball play (for 90 balls or ",30 games) by displaying the message "Check Switch
##",
list-
ing each problem switch by number. (The game program compensates the game play requirements affected
by each disabled switch to allow 'nearly normal' play. This helps keep
ROLLERGAMES
earning, until the
service technician can repair the problem, bringing the game back to its normal good profits!)
To verify the problem, refer to the Test! Diagnostic Procedures text describing Switch Testing, and check each
reported switch using applicable Switch Levels and Switch Edges tests. Atways check switch operation using
a ball, to simulate game conditions.
(Switch problems may often be resolved by adjusting the wire switch
actuators, fixing switch circuitry problems, securing loose connectors, etc. Mechanisms using 'opto switches'
(drop targets, etc.) need to be checked for proper power connections
(+
12V dc and ground).
Pinball Missing.
ROLLERGAMES
normally uses three balls; however, it will operate with two balls. This
message announces that a ball is missing or stuck somewhere. When the ball is located, return it to the game
via the Outhole. Other possibilities forth is problem could be malfunctions of the Ball Trough switches (#11, #12,
or #13) or the Shooter Lane switch (#20).
Coin Door Slam Switch Stuck. This message indicates that the Slam Tilt switch, which is not usually On,
remains in the On position after the game is switched on. The stuck switch is essential for game play and should
be cleared to permit proper game operation.
