Heschen P80/38 Electromagnetic Solenoid User Manual

1. Introduction

This manual provides instructions for the safe and effective use of the Heschen P80/38 Electromagnetic Solenoid. Please read this manual thoroughly before installation and operation to ensure proper function and to prevent damage or injury. This device is designed for industrial holding applications requiring a strong, controlled magnetic force.

2. Safety Information

• The solenoid operates on 24V DC. Ensure the power supply matches this voltage to prevent damage to the unit.
• This device is designed to be energized under load. Prolonged operation without a magnetic load can cause overheating and permanent damage to the unit. The maximum operating temperature limit is 120°C.
• Always disconnect power before performing any installation, maintenance, or troubleshooting procedures.
• Handle with care. The solenoid can exert significant force when energized, posing a pinch hazard.
• Keep away from sensitive electronic devices and magnetic storage media when energized.

5. Setup and Installation

1. Mounting: Securely mount the solenoid using the M8 fixed thread. Ensure the mounting surface is stable and capable of withstanding the solenoid's maximum attraction force (100kg). Proper mounting prevents movement and ensures consistent performance.
2. Electrical Connection: Connect the solenoid to a stable 24V DC power source. Observe correct polarity if required by your specific application, although for simple magnetic attraction, DC electromagnets typically function regardless of polarity. Ensure all connections are secure and insulated.
3. Cable Management: The solenoid comes with a 23 cm cable. If a longer cable is needed, use appropriate gauge wiring and connectors to extend it, ensuring the extension can handle the required current (0.55A).

6. Operating Instructions

The Heschen P80/38 solenoid operates by generating a magnetic field when 24V DC power is applied, which then attracts magnetically conductive materials.

Optimal Performance Conditions:

For optimal performance and to achieve the maximum 100kg suction force, the object to be attracted must meet the following criteria:

• It must be a magnetically conductive metal.
• The contact surface of the object must be flat and smooth.
• The object should have a thickness of 6mm or more.
• The contact area of the object should be equal to or larger than the solenoid's suction cup surface.

Operation Under Load:

The solenoid is designed for continuous operation when under a magnetic load. It is crucial to avoid energizing the unit for extended periods without a magnetic load, as this can lead to excessive temperature rise and potential damage.

7. Maintenance

• Cleaning: Keep the solenoid's contact surface clean and free from dust, debris, or rust to ensure maximum holding force and efficient operation. Use a dry, soft cloth for cleaning.
• Inspection: Regularly inspect the power cable for any signs of wear, cuts, or damage. Replace damaged cables immediately to prevent electrical hazards.
• Storage: Store the solenoid in a dry environment, away from extreme temperatures and corrosive substances.
• Service: There are no user-serviceable parts inside the solenoid. Do not attempt to disassemble the unit, as this will void any potential warranty and may cause damage.

8. Troubleshooting

Common Issues and Solutions:

• Reduced Suction Force:
  • Cause: Object not magnetically conductive. Solution: Ensure the attracted material is ferrous (e.g., iron, steel).
  • Cause: Rough or uneven contact surface. Solution: Ensure both the solenoid's surface and the attracted object's surface are flat and smooth.
  • Cause: Object thickness less than 6mm. Solution: The object should be at least 6mm thick for optimal magnetic coupling.
  • Cause: Object area smaller than solenoid's surface. Solution: The attracted object's surface area should be equal to or larger than the solenoid's contact area.
  • Cause: Rusty or dirty surfaces. Solution: Clean both surfaces thoroughly. Rust and debris significantly reduce magnetic force.

• Solenoid Overheating:
  • Cause: Prolonged operation without a magnetic load. Solution: Ensure the solenoid is always under a magnetic load when energized for extended periods.
  • Cause: Incorrect input voltage. Solution: Verify the power supply provides exactly 24V DC.
• No Attraction:
  • Cause: No power or incorrect voltage. Solution: Check the 24V DC power supply and all electrical connections.
  • Cause: Object is not magnetically conductive. Solution: Confirm the material to be attracted is ferrous.
  • Cause: Damaged solenoid. Solution: If all other checks fail, the solenoid may be faulty. Contact support.
