Frequently Asked Questions & Troubleshooting
Why is the magnet running hot? "Power to Lock" devices like magnetic locks can become warm during normal operation due to the constant power they require. However, excessive heat is often caused by:
- Incorrect Voltage: Supplying 24V DC to a magnet set for 12V DC operation.
- Insufficient Amperage: The power supply is not providing enough current, causing the magnet to heat up as it struggles to maintain its hold.
- Voltage Drop: Using an inadequate wire gauge over a long cable run can reduce the current reaching the magnet, leading to overheating.
Why is the armature plate vibrating? This is typically due to one of the following:
- A faulty or underrated power supply.
- The magnet is set for 24V DC operation, but the power supply is only 12V DC.
Why won't the magnet lock properly? If the door can be pulled open easily, the most common causes are:
- Incorrect alignment between the armature plate and the magnetic lock.
- A faulty or underrated power supply.
- A voltage mismatch (e.g., a 24V DC magnet with a 12V DC power supply).
Technical Tips
- Verify Wiring: This magnetic lock operates on either 12V DC or 24V DC. Before powering on, double-check that the wiring connections match your selected power supply (12V or 24V). Failure to do so can cause the lock to overheat or fail to engage, potentially damaging the system over time.
- Maintenance: Periodically clean the surfaces of both the magnet and the armature plate using a light oil to ensure optimal performance.
