SPACE BALLZ TROUBLESHOOTING GUIDE
CAUSE
1) Check to make sure there is a ball in the upper acrylic structure. There
should only be ONE ball being held in the upper structure. If there is more
than ONE ball - there is a problem with the micro-switch that shuts off power
to the second vertical elevator. If power is not shut off to this riser after one
ball is loaded, the addition of multiple balls in this holding area will cause a
jam.
2 Check to make sure that the micro-switch in the upper acrylic structure is
connected and working properly. There is the possibility that the metal wire
on this micro-switch could become lodged above the acrylic and not shut off
the motor. In that case, check to make sure there is proper length on the
switch wire and that it clears the acrylic. The weight of certain balls could
cause this wire to "push" either to the right or left side when a ball is loaded
causing a elevator to continue working and causing a second ball to load. In
his case, the weight of both balls may push the switch wire down - but since
there are two balls in the holding area, both balls may be loaded into the
crane causing a jam.
3)Check to make sure that the solenoid in the upper acrylic ball structure is
working properly and that the connectors of the wires going to this solenoid
are properly seated. If balls continue to run into the crane, then there is a
possibility that the solenoid is not working properly. Check to make sure that
the solenoid plunger is in place and that the spring is good. Check the
solenoid board (MB13007.PCB) and ensure that it is working properly.
1) The most common reason for an Err-20 is that there is not enough balls in
the middle acrylic ball structure. There should be at least three balls in this
staging area in order to activate the motor switch and turn off the power to
the large ball elevator. Check to make sure that the third ball in the holding
area properly puts enough weight onto the switch wire in order to activate
the switch in the acrylic track. You may need to adjust the metal wire in
order for the ball to properly push the wire down.
2) Check to make sure you have enough balls in the system and that they are
not jammed somewhere else. If three balls are not present in the middle
holding area, and a ball is not pressing on the metal switch wire, an Err-20
will be displayed on the screen. The balls may be jammed up somewhere in
the game or the power to the large elevator be interrupted or the elevator
motor could be faulty.
3) After playing the game - there might be a possibility of the balls collecting
behind the playfield. This is caused by two things: A) The machine may not
be sitting entirely level on the floor. If the front of the cabinet is higher than
the rear of the cabinet - the balls will be acting against gravity and may not
fall into the first elevator as is designed. B) The balls may be damaged,
deformed, or under-inflated which is causing them to not roll perfectly and
could catch in parts of the collection area. Check to make sure that the balls
are in good condition and are free from damage including small bumps or
tears in the seams.
