ALIGNMENT TEST
BEFORE THE TEST
Before aligning the needle, you should check that P17, Needle Adjustment (See
Programmable Adjustments mode 16 for more details) is set to zero.
ENTER
The Alignment test can be entered from the Prize arm, indicator and motor test
by pressing the Test button once or by pressing the Test button four times from
attract mode. The four-digit LED display will show
.
It is important to align the needle correctly so that the player does not feel
“cheated” by the needle pointing to one number, but the lighthouse level lamps
actually moving by a different amount. Aligning the needle can easily prevent
this.
DURING THE TEST
The alignment of the needle to the artwork can be adjusted. Pressing service and
the display will step through from U01 to U48 and then back to U48. These are
the 48 different positions of the needle. Pressing the start button will cause the
needle to move to the currently selected position.
Choose position
and press the
start button. The needle should stop
exactly in the middle of the “5” region on
the top of the wheel (as shown). If the
needle does not stop exactly in the middle
of the 5 region (the top middle of the
artwork), loosen the bolts that mount the
stepper motor (Accessed from the rear of
the machine, see the Parts location
Diagram page 34). Then rotate the needle
so that it is in the exact center of the
number 5 region. Then retighten the
mounting bolts of the stepper motor.
In cases where it is impossible for the user to align the needle properly, please
use the programmable adjustments setting P17 to adjust the needle via software
(See Programmable Adjustments mode page 16 for more details).
■ EXIT
The Alignment test is exited into the Program Settings Modes by pressing the
Test button once.
* NOTE! *
In nearly all cases, P 17 should be set to its default value of 0.
Only alter this setting in cases of extreme misalignment!
