1. Introduction
This manual provides detailed instructions for the installation, operation, maintenance, and troubleshooting of the Nity NYZ16888 Game Board. This motherboard is specifically designed for gantry claw vending crane machines, serving as the central control unit for various machine functions including coin acceptance, joystick control, motor operation, and prize dispensing. Please read this manual thoroughly before installation and operation to ensure proper functionality and safety.
2. Setup Instructions
Careful installation is crucial for the correct operation of the NYZ16888 game board. Ensure all power is disconnected from the crane machine before proceeding with any wiring.
2.1 Component Overview
2.2 Wiring Connections
Refer to the labels on the game board and your crane machine's wiring diagram for precise connections. The board supports multiple voltage inputs and various control signals.
- Power Supply: Connect the appropriate power supply to the labeled terminals. The board supports 5V, 12V, 24V, and 48V inputs. Ensure correct voltage and polarity to avoid damage.
- Coin Acceptor: Connect your coin acceptor to the 'COIN' input terminal. Ensure the ground (GND) connection is also made.
- Joystick/Buttons: Connect the joystick and control buttons (UP, DOWN, LEFT, RIGHT, FORWARD, BACK, SHAKE, SERVICE) to their respective labeled pins. Each input typically requires a signal wire and a common ground.
- Motor Control: The board features multiple relays (HF115F, 8A 250VAC / 8A 24VDC) for controlling crane motors (gantry movement, claw open/close). Connect the motor control wires to the relay outputs as per your machine's specifications.
- Output/Prize Dispenser: Connect any prize dispenser or other output mechanisms to the 'OUT' terminal.
- Display/Sensor: The DB-15 connector on the right side is typically used for display or sensor feedback. Consult your machine's specific documentation for this connection.
Warning: Incorrect wiring can lead to severe damage to the game board and other components. If you are unsure, consult a qualified technician.
3. Operating Instructions
Once the NYZ16888 game board is correctly installed and powered, the crane machine should be ready for operation.
- Power On: Turn on the main power switch for the crane machine. The game board should initialize.
- Insert Coin: Insert the required number of coins into the coin acceptor. The machine should register the credit.
- Control Claw: Use the joystick and control buttons (UP, DOWN, LEFT, RIGHT, FORWARD, BACK) to position the gantry and claw over the desired prize.
- Activate Claw: Press the 'SHAKE' or 'SERVICE' button (depending on machine configuration) to lower and attempt to grab a prize.
- Prize Dispense: If a prize is successfully grabbed, the machine will move the claw to the prize chute and release it.
3.1 Configuration (SET Button)
The 'SET' button, located on the top-left of the board (see Figure 1), is used to enter the configuration menu. Typically, holding this button during power-up or pressing it during idle mode will allow access to settings such as game difficulty, coin settings, and timer adjustments. Refer to your crane machine's specific manual for detailed menu navigation and parameter adjustments.
4. Maintenance
Regular maintenance helps ensure the longevity and reliable performance of your NYZ16888 game board.
- Keep Clean: Periodically inspect the board for dust and debris. Use compressed air or a soft, dry brush to gently clean the surface.
- Avoid Moisture: Ensure the game board is kept in a dry environment, away from any liquids or excessive humidity.
- Secure Connections: Regularly check all wiring connections to ensure they are secure and free from corrosion. Loose connections can cause intermittent issues.
- Power Stability: Ensure the power supply to the machine is stable and within the specified voltage ranges to prevent electrical damage.
