SPACE BALLZ TROUBLESHOOTING GUIDE
PROBLEM
CAUSE
SOLUTION
1) Check to make sure the optic sensor on the left (left - facing the front of
the cabinet) is in good condition and receiving 12 volts.
2) Ensure that the crane mechanism passes over the sensor. It is possible
that the sensor might have moved and the metal assembly is not breaking
the opto.
3) If the sensor is in good condition and receiving power, then the only other
issue could be a bad input IC. Replace the U10 Input IC with one of the
spares (U11 or U12).
ERROR 22 -
(Err-22)
Left robotic crane sensor fault
Game will not power up
1) Game not plugged in or turned ON
2) No power to the receptacle
3) Game input line AC fuse broken
4) Power supply broken
1) Game not plugged in or turned ON. Check to make sure the game is
plugged into a grounded outlet and that it is receiving the proper line
voltage. Make sure that the switch is powered ON.
2) No power to the receptacle. Check to make sure the outlet is receiving the
proper line voltage and that all power supplies inside the game are set to the
proper line voltage.
4) Check to make sure the power supply is receiving the proper input voltage
and that they are producing the correct output voltage.
3) Game input line AC fuse broken. Check and make sure the fuse is not
broken. Perform a continuity check on the fuse. Only replace fuse with a
similar one with the same specifications.
ERROR 23 -
(Err-23)
1) Check to make sure the optic sensor on the right (right - facing the front of
the cabinet) is in good condition and receiving 12 volts.
2) Ensure that the crane mechanism passes over the sensor. It is possible
that the sensor might have moved and the metal assembly is not breaking
the opto.
Right robotic crane sensor fault
3) If the sensor is in good condition and receiving power, then the only other
issue could be a bad input IC. Replace the U10 Input IC with one of the
spares (U11 or U12).
ERROR 24 -
(Err-24)
1) The micro-switch located within the Bonus Hole acrylic structure is not
properly working. Check to make sure the metal switch wire is bent properly
and will react to a passing ball.
2) Check all wire connection going to the switch and ensure that it is
receiving 12 volts. If the switch is receiving power but will not send an input -
replace the switch.
Bonus hole micro-switch fault
3) If the switch is in good condition and receiving power, then the only other
issue could be a bad input IC. Replace the U10 Input IC with one of the
spares (U11 or U12).
