LED indicators on Hop Pad Interface Board
Left LED is left foot
Middle LED is middle position
Right LED is right foot
Note: If a sensor beam is blocked - these LED's will not light until obstruction is removed.
If LED's are functioning correctly, then Hop Pad and Interface Board is OK.
- Check AACE5504 cable to Microgen 2300 board.
- Replace Microgen 2300 board.
If LED's are not functioning, continue troubleshooting below, the pad sensors are not registering on this board.
Problem may be emitters, detectors, cables or the Pad Interface Board itself.
Emitter Board Troubleshooting
Emitter boards are under the front green metal closest to the cabinet.
There are 2 emitter boards, and each have 2 emitters per beam.
Verify the emitter boards have 12 volts on cable AACE5512 and also on
the jumper cable between circuit boards AACE5513.
Replace emitter board if needed. Part # AACB2804
Detector Board Troubleshooting
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.
There are 2 Detector boards, and each have 1 detector per beam.
The boards receive power by the ribbon cable part # AACE5505 and 5506
Ensure these ribbon cables are flat and not pinched or scraped.
Ribbon cables plug into the Pad Interface Board—Ensure the left ribbon cable is
plugged into top socket, and the right ribbon cable is plugged into the bottom socket.
Inspect ribbon cables and replace if needed. (Part # AACE5505 and 5506)
Replace detector board if needed. (Part # AACB2803)
