• Motor Control: The board regulates the motor’s speed and functions, ensuring that it operates smoothly during crushing.
  
• Monitoring and Diagnostics: The control board is equipped with sensors and diagnostic systems that monitor the health of various parts of the crusher. This includes tracking temperatures, pressures, and other operational parameters to detect any potential problems.
  
• Safety Features: It also ensures that safety mechanisms are in place, such as overload protection, emergency shutdown, and fault detection systems.
  

Common Problems with the Fintec 1107 Control Board
Electrical control boards like the one in the Fintec 1107 are susceptible to various issues over time. Common problems that can occur with part number 301200-14041157 include:

1. No Power to the Crusher:
   • Symptoms: The crusher fails to power on despite the battery being charged, and no lights or signals appear on the control panel.
     
   • Possible Causes: A blown fuse, malfunctioning relay, or a short circuit in the control board could cause a lack of power. Additionally, wiring issues or a damaged connection between the battery and the control board could be to blame.
     
   • Solution: Inspect the fuses and relays associated with the control board. If any are damaged, replace them with components of the correct specifications. Check all connections to ensure there are no loose or damaged wires. If the issue persists, the control board itself may need to be replaced.
     
2. Erratic Performance:
   • Symptoms: The crusher runs at inconsistent speeds, makes strange noises, or operates erratically.
     
   • Possible Causes: Faulty sensors, malfunctioning relays, or a failing control board can cause irregular behavior. Additionally, a faulty power supply to the control board can disrupt its ability to regulate the crusher’s functions properly.
     
   • Solution: Conduct a full diagnostic check of the control board using a multimeter or other diagnostic tools. Pay special attention to the sensor readings and check for any signs of failure. If any sensors are damaged or not providing correct readings, replace them.
     
3. Overheating or Burning Smell:
   • Symptoms: Overheating in the control panel, often accompanied by a burning smell, or tripped circuit breakers.
     
   • Possible Causes: Overheating can result from an overloaded circuit, short-circuited components, or improper voltage regulation from the control board.
     
   • Solution: Turn off the machine immediately and allow it to cool down. Inspect the control board and surrounding components for signs of damage, such as melted wires or scorched areas. Ensure that the control board’s cooling system is functioning properly and that the machine is not overloaded. Replace any components that show signs of overheating.
     
4. Faulty Diagnostics or No Fault Code Display:
   • Symptoms: The control board fails to display any fault codes despite the machine malfunctioning.
     
   • Possible Causes: A malfunction in the diagnostic system or a fault in the control board’s communication interface can cause this issue.
     
   • Solution: Check the diagnostic wiring and communication systems to ensure they are functioning correctly. If the communication between the board and diagnostic system is interrupted, this could prevent fault codes from being displayed. In some cases, the control board may need to be reset or reprogrammed.
     

Troubleshooting the Fintec 1107 Control Board
To troubleshoot issues with the Fintec 1107’s control board, follow these steps:

1. Check the Power Supply:
   • Ensure the battery is fully charged and all fuses, relays, and circuit breakers are intact. Measure the voltage supplied to the control board to confirm it is within the proper range.
     
2. Perform Diagnostic Tests:
   • Use a diagnostic tool or multimeter to check for power continuity and sensor readings. Look for any irregularities that might indicate a faulty component or connection.
     
3. Inspect Wiring and Connections:
   • Examine all wiring connected to the control board, including sensor wires, power cables, and relay connections. Look for signs of wear, corrosion, or damage that could interrupt electrical flow.
     
4. Inspect and Test Sensors:
   • Check the performance of sensors connected to the control board. If a sensor is malfunctioning, it could send incorrect signals to the control board, causing erratic machine behavior.
     
5. Replace the Control Board if Necessary:
   • If all else fails, the control board itself may need to be replaced. Before doing so, ensure that the new board is compatible with the Fintec 1107 and has the correct part number (301200-14041157).
     

Preventative Measures and Maintenance for the Control Board
To avoid future issues with the control board in the Fintec 1107, follow these preventative maintenance tips:

1. Regular Cleaning:
   • Dust, debris, and dirt can accumulate in the control panel, causing overheating or short-circuiting. Regularly clean the area around the control board to prevent buildup.
     
2. Scheduled Inspections:
   • Perform regular inspections of the electrical components, including the control board. Look for signs of wear or overheating, and replace any damaged parts promptly.
     
3. Use Proper Voltage:
   • Ensure that the machine is operating with the correct voltage. Incorrect voltage can damage the control board and other electrical components.
     
4. Monitor Operational Performance:
   • Regularly monitor the machine’s performance, paying attention to any unusual noises or erratic behavior. Early detection of issues can prevent more severe damage to the control board.
