4. Opsætning og installation

Proper installation is crucial for the safe and reliable operation of the contactor. Refer to the wiring diagrams provided with your specific application or system documentation.

4.1 Montering

• The contactor can be mounted on a 35mm DIN rail or directly to a panel using screws.
• Sørg for tilstrækkelig ventilation omkring kontaktoren for at forhindre overophedning.
• Mount the contactor vertically on a flat, stable surface.

4.2 Ledningsføring

• Connect the main power circuit to terminals 1L1, 3L2, 5L3 (input) and 2T1, 4T2, 6T3 (output).
• Connect the control circuit (120V AC) to the coil terminals A1 and A2.
• Utilize auxiliary contacts (e.g., 13 NO, 21 NC) for control logic as required by your application.
• Ensure all wire connections are tight and secure to prevent loose connections and potential arcing.
• Use appropriate wire gauges for the current ratings.

5. Betjeningsvejledning

The TeSys D Contactor operates by energizing its coil, which creates an electromagnetic field that pulls the armature, closing the main power contacts. When the coil is de-energized, a spring returns the armature to its original position, opening the main contacts.

• Aktivering af spolen: Apply 120V AC to terminals A1 and A2. The contactor will audibly click as the main contacts close.
• Afbrydelse af spolen: Remove the 120V AC supply from terminals A1 and A2. The contactor will release, and the main contacts will open.
• Statusindikation: Some models may include a visual indicator to show the contactor's state (open/closed).

6. Vedligeholdelse

Regular inspection and maintenance can extend the lifespan of the contactor and ensure reliable operation.

• Visuel inspektion: Kontrollér regelmæssigt for tegn på slid, skader, misfarvning eller løse forbindelser.
• Rensning: Keep the contactor free from dust, dirt, and debris. Use a dry, non-conductive cloth or compressed air. Do not use solvents.
• Kontaktinspektion: For critical applications, periodically inspect the main contacts for pitting or excessive wear. Replace the contactor if contacts are severely worn.
• Tæthedskontrol: Re-tighten all terminal screws to the specified torque values (refer to product label or Schneider Electric documentation) during routine maintenance.

7. Fejlfinding

Dette afsnit omhandler almindelige problemer, der kan opstå under kontaktorens drift.

• Kontaktoren aktiveres ikke:
  • Check if 120V AC is present at coil terminals A1 and A2.
  • Verify control circuit wiring for breaks or loose connections.
  • Inspect the coil for damage (e.g., burnt smell, visible charring).
• Kontaktor brummer overdrevent:
  • Ensure the mounting screws are tight.
  • Check for foreign objects obstructing the armature movement.
  • Verify the coil voltage er inden for specifikationerne.
• Kontaktor overopheder:
  • Check for excessive load current exceeding the contactor's rating.
  • Ensure proper ventilation and ambient temperature are within limits.
  • Inspect main contacts for signs of pitting or high resistance.
• Main Contacts Fail to Close/Open Reliably:
  • Inspect contacts for wear, welding, or foreign material.
  • Bekræft spolevolumentage and ensure it is stable.
  • Check for mechanical obstructions.
