Err5 – PRIZE SENSOR BLOCKED or PRIZE SENSOR FAULTY
This error usually occurs if the prize sensor is blocked or a prize is jammed
in the prize chute, blocking the infrared beam of the prize sensor for longer
then 5 seconds.
The sensor can be tested using the switch test, (See Page 12 for Details). If
the sensor is blocked C7 will be displayed in this test. Clear what ever is
blocking the sensor and the error will clear itself.
If you cannot find anything blocking the sensor, there could be faulty
infrared sensors or receivers on the prize sensor. The sensor PCB‟s should
be returned to your nearest LAI Games distributor for repair.
The Prize Sensor is designed around 12 pairs of infrared detectors and
LEDs. Blocking the infrared path of any one of the 12 beams will trigger a
common output. There are 6 orange LEDs on each Sensor PCB to help
indicate the active pairs of infrared beams.
Err6 – All PRIZE ARMS STATUS are DISABLED.
This error will only be displayed if programmable adjustments P20 to P27
(Prize Arm Status) are all set to OFF (Disabled).
There should be at lest one Prize Arm set to Status to ON. Push the test
button once to enter directly to P20 to P27 in adjustment mode, locate
what prize arms need to be active and set that Prize Arm Status to ON,
(See Page 16 for Details).
Err7– NEEDLE INDEX SENSOR ERROR.
This error will only be displayed if Needle Index optic sensor on the
Wheel PCB is not activating. This error will usually occurs because the
metal U bracket, that form part of the needle rotor structure is not bent
correctly and is not activating the sensor on the wheel PCB. To check this,
remove the wheel and needle mounting from inside the Lighthouse
fiberglass model (accessed from the rear).
Check the Compass Wheel PCB to see that the Needle Index arm is
passing through the optical sensor. The sensor can be tested using the
switch test, (See Page 12 for Details). If the sensor is blocked C9 will be
displayed in this test.
Err8– PRIZE SENSOR ALIGNMENT.
This error can occur if the sensor output pulses or “flickers” due to miss
alignment for more then 20 times every 5 seconds.
The Prize Sensor can be aligned by loosening the five mounting points and
adjusting the sensor PCBs to each other. The sensor can be tested using the
switch test, (See Page 12 for Details). If the sensor is blocked C7 will be
displayed in this test.
If you cannot find anything, there could be faulty infrared sensors or
receivers on the prize sensor. The sensor PCB‟s should be returned to your
nearest LAI Games distributor for repair.
The Prize Sensor is designed around 12 pairs of infrared detectors and
LEDs. Blocking the infrared path of any one of the 12 beams will trigger a
common output. There are 6 orange LEDs on each Sensor PCB to help
indicate the active pairs of infrared beams.
