| What's
the Problem |
Is
this the Cause |
Here's
the Solution |
| 1)
Token inserted in coin box, it registers on display panel,
but system does not begin operation. |
1a)
No power at electrical outlet, which light box is plugged
into. |
1a)
Check Circuit breaker at service panel. |
| 1b)
No (5VDC) signal from microprocessor. |
1b)
Check for voltage (5VDC) inside light box. For “A” machine
check between red and green of belden cable. For “B” machine
check between white and green. |
| 1c)
No power (115VAC) at light box terminal strip. |
1c)
Check for (115VAC) between black and white wires on “power”
section of terminal strip. If no power is detected, check
power cord. |
| 1d)
No power at secondary side of transformer. (3 wire side).
|
1d)
If there is 115VAC at primary side of transformer (2 wire
side), but there is not 12VAC coming out of the secondary
side (3 wire), replace transformer or call ABC. |
| 2)
Token inserted, registers on display panel, all components
begin operation, except “yellow” light. |
2a)
Light bulb burned out. |
2a)
Replace light bulb. |
| 2b)
Defective “yellow light” relay. |
2b)
Replace “7227” yellow light relay. |
| 2c)
No triggering voltage to yellow light relay from “controller”.
|
2c)
Replace “7234 or 7995” controller. |
| 2d)
Defective yellow light assembly. |
2d)
Replace yellow light assembly. |
| 2e)
Bad ground on light assembly. |
2e)
Repair ground connections. |
| 2f)
Poor connection in light box. |
2f)
Tighten all screws on circuit board. NOTE: “do not over
tighten screws, they could break off”. |
| 3) Token inserted, registers
on display panel, all components begin operation except
pitching machine. For dual machine systems, remember to
follow “solution” on appropriate circuit. NOTE: To isolate
problem, unplug light box and plug directly into outlet.
If pitching machine does not run, proceed to problem 1
in pitching machine section. If machine does operate,
proceed in this section. |
3a) Loose wire on machine pigtail cord
coming from light box. |
3a) Remove female end of plug and check
for loose wires. |
| 3b) Defective MACH “A”/ MACH “B” relay.
|
3b) Replace “7227” pitch relay inside
light box. |
| 3c) Defective MACH “A”/ MACH “B” mercury
displacement relay. |
3c) This relay can be checked with a
voltmeter. If no voltmeter is available, replace relay
or call ABC. |
| 3d) Bad connection in pitching machine
circuit. |
3d) Check connections of all wiring from
“power in”, to “mercury displacement relay”, and back
to “pitch” section on the terminal strip inside the light
box. |
| 3e) Defective “7234” or “7995” controller
block. |
3e) Replace “7234” or “7995” controller
block in the light box. |
| 4) Token inserted, registers
on display panel, all components begin operation except
red light. NOTE: Pinch Roller will not operate if red
light is not functioning. This is a fail-safe condition
built into the system. |
4a) Red light bulb burned out or broken.
|
4a) Replace “red light” bulb. |
| 4b) Defective “red light” relay. |
4b) Replace “7227” red light relay inside
the light box. |
| 4c) Poor connection in light box. |
4c) Tighten all screws on circuit board.
NOTE: DO NOT OVER TIGHTEN SCREWS, THEY WILL BREAK OFF.
|
| 4d) Bad “fail safe” relay. |
4d) Replace “7225” fail-safe relay inside
the light box. |
| 4e) No triggering voltage to red light
relay from controller. |
4e) Replace “7234” or “7995” controller
relay. |
| 4f) Bad ground on light assembly. |
4f) Repair ground connections. |
| 5) Token inserted, registers
on display panel, all components begin operation except
pinch roller. For dual machine system, remember to follow
“solution” on appropriate circuit. |
5a) Pinch roller set screw is loose on
pinch roller motor shaft. |
5a) tighten pinch roller set screw on
pinch roller wheel. Set screw must tighten against the
flat spot on the Pinch roller motor shaft. |
| 5b) Bad or loose connection on power
cord, going from “Light box” to “Pinch roller motor”.
|
5b) check wires for loose connection.
Trace from light box to pinch roller motor. |
| 5c) Defective “feeder” relay. |
5c) When both lights come on, check for
115VAC at pinch roller connection, with wires connected
to motor. If no power (115VAC) is present, replace “7227”
Feed “A”/ Feed “B” relay. |
| 5d) Defective pinch roller motor. |
5d) Duplicate test in solution “C”. If
power is present replace pinch roller motor. |
| 5e) Defective “fail-safe relay”. |
5e) Replace “7225” fail-safe relay. |
| 6) Pinch roller begins operating when
light box is plugged into outlet. No lights are on. |
6) Defective “feeder relay”. |
6) Replace “7227” Feed “A”/ Feed “B”
relay ion light box. |
| 7) Red light and pinch roller
both come on as soon as token is inserted, (no delay between
yellow). |
7a) Defective “red light relay”. |
7a) Replace “7227” red light relay inside
the light box. |
| 7b) Bad controller. |
7b) Replace “7234” or “7995” controller
relay inside the light box. |
| 8) Game has ended, lights
go out, pinch roller stops, but pitching machine continues
to run after the 10 minute “off delay”. |
8a) Bad “controller”. |
8a) Replace “7234” or “7995” controller
inside the light box. To verify, unplug light box, wait
5 - 10 seconds and plug back in. If machine does not run,
“7234” or “7995” controller is defective. |
| 8b) Defective “machine” relay |
8b) Replace “7227” MACH “A”/ MACH “B”
relay. |
| 9) Token inserted and both lights come
on at the same time. |
9) Bad controller. |
9) Replace “7234” or “7995” controller
relay inside the light box |
| 10) Pitching machine runs
as soon as light box is plugged into power. No lights
come on. |
10a) Defective “machine relay”. |
10a) Replace “7227” MACH “A”/ MACH “B”
relay. |
| 10b) Bad “controller relay”. |
10b) Replace “7234” or “7995” controller
relay inside the light box. |
