6. Налаштування та встановлення

The TZ-8108 limit switch is designed for wall mount applications. Proper installation is crucial for safe and reliable operation.

1. Відключення живлення: Before beginning any installation, ensure that the power supply to the circuit where the switch will be installed is completely disconnected and locked out.
2. Місце монтажу: Select a suitable mounting location that is stable, free from excessive vibration, and allows for the proper operation of the lever arm. Consider the path of the object that will actuate the switch.
3. Монтаж: Secure the limit switch to the desired surface using appropriate fasteners through the mounting holes. The mounting size is 56 x 21 mm (2.2 x 0.8 inches). Ensure the switch is firmly attached.
4. Електропроводка: Connect the electrical wires to the switch terminals according to your application's wiring diagram. The switch has a 1NO, 1NC (SPDT) contact configuration. Refer to the specific circuit requirements for connecting the Normally Open (NO) and Normally Closed (NC) contacts. Ensure all connections are tight and secure.
5. Lever Arm Adjustment: Adjust the rotary lever arm to the desired position. The arm can be rotated 90 degrees left or right to align with the actuating mechanism. Ensure the roller makes proper contact with the moving part to trigger the switch reliably.
6. Перевірка: After installation and wiring, double-check all connections and mounting security.
7. Відновлення живлення: Restore power to the circuit and test the switch's operation carefully.

7. Операція

The Aexit TZ-8108 is a momentary action limit switch. Its operation is straightforward:

• When the roller on the lever arm is actuated by a moving object, the internal contacts of the switch change state.
• The Normally Open (NO) contact will close, and the Normally Closed (NC) contact will open.
• Once the actuating force is removed, the lever arm returns to its original position, and the contacts revert to their initial state (NO opens, NC closes).
• The adjustable lever arm allows for fine-tuning the point at which the switch is actuated, providing flexibility for various applications.

8. Технічне обслуговування

Regular maintenance helps ensure the longevity and reliable performance of your limit switch:

• Огляд: Periodically inspect the switch for any signs of physical damage, wear on the roller or lever arm, or loose connections.
• Прибирання: Keep the switch clean and free from dust, debris, or foreign objects that could impede the movement of the lever arm or roller. Use a soft, dry cloth for cleaning. Do not use harsh chemicals or abrasive materials.
• Змащення: The roller mechanism is generally self-lubricating. Avoid applying excessive lubricants unless specifically recommended by the manufacturer, as this can attract dust.
• Захист навколишнього середовища: Ensure the switch remains within its specified IP20 environmental conditions. Protect it from excessive moisture or corrosive substances.

9. Вирішення проблем

If the limit switch is not functioning as expected, consider the following troubleshooting steps:

• Немає відповіді:
  • Перевірте, чи є живлення схеми активним.
  • Verify all wiring connections are secure and correct according to the circuit diagram.
  • Ensure the lever arm and roller are making proper contact with the actuating object and are moving freely.
  • Inspect for any physical obstruction preventing the lever from moving.
• Переривчаста робота:
  • Перевірте, чи не закріплені проводки.
  • Ensure the actuating object consistently makes firm contact with the roller. Adjust the lever arm position if necessary.
  • Inspect the roller and lever arm for wear or damage that might cause inconsistent actuation.
• Switch Stuck:
  • Check for physical damage or foreign objects jamming the lever mechanism.
  • Ensure the mounting is not causing undue stress or binding on the switch mechanism.

If problems persist after performing these checks, it is recommended to consult a qualified technician or contact the product supplier for further assistance.
