Coin Accepted But Crane Gantry and Claw Won't Move

Posted

When a sensor is blocked, usually the crane accepts the payment for play but may show zero credit on the display and the joystick will not operate the gantry and claw.

Occasionally payment is accepted, credit given and the game starts but may end before full play has completed.

To solve this issue, check the sensors in the machine and ensure it is not obscured:

How to do this: While the machine is not in operation, open the door under the main crane play area.

Check that the red sensor indicator light is not flickering or blocked on the meter pack.

If it is then check the sensors. These can be fitted in various locations, depending on the type of machine. Some have a switch (or opto-sensor) activated by a physical flap, some have reflective sensors and some have “strip” barriers. Be aware that those machines with strip barriers are affected by strong ambient light like sunlight, illuminating the win area and interfering with the infra-red receivers.
