SENSOR PAD DIAGNOSTICS
Step 1:
The most common issue is a dirty emitter or detector on the pad itself.
If a beam is blocked the game will not register anything until the obstruction is removed.
Solution: Clean the clear plexi that is protecting the emitters and detectors on both sides of
pad.
If after cleaning the emitter and detector clear plexi, the game still
does not register a hop, then continue to Step 2.
Step 2:
Remove the pad from the game and look at detector board LED indicators.
Remove the slotted orange metal by re-
moving 5 tapered screws
Also remove the 4 panhead screws holding
the black plastic sheet.
Remove both orange metal edgings by
removing 3 tapered screws on each
side.
Lift up the black plastic and
carefully slide out pad from
main cabinet.
Tipping hop pad up, the detector boards
can be seen under the clear plexi.
The green LED is normal ON.
It will be OFF if path is blocked
If LED is dimly lit, the emitter board on the other end of the
pad is blocked or faulty.
