4. Configuració i instal·lació

4.1 Muntatge

The Finder 22.32.0.024.4320 contactor is designed for DIN rail mounting. To install:

1. Ensure the DIN rail is securely fastened within the enclosure.
2. Hook the top edge of the contactor onto the DIN rail.
3. Press the bottom edge of the contactor firmly until it clicks into place on the DIN rail.
4. Verify the contactor is securely attached and does not wobble.

4.2 Connexions de cablejat

Refer to the wiring diagram and terminal markings on the contactor for correct connections. The contactor has two main sets of terminals:

• Coil Terminals (A1, A2): Connect the 24V AC/DC control voltage to these terminals. Polarity is generally not critical for AC/DC coils, but always follow specific instructions if provided.
• Power Contact Terminals (1, 2, 3, 4): These are the main power contacts. Terminals 1 and 3 are the inputs, and 2 and 4 are the outputs for the two normally open poles. Connect the load circuit to these terminals.

Ensure all wire connections are tight and secure to prevent loose connections, which can lead to overheating or intermittent operation.

5. Instruccions de funcionament

The Finder 22.32.0.024.4320 is an automatically operated modular contactor. Its function is to switch electrical loads on or off based on the energization of its control coil.

1. Estat desenergitzat: Quan no voltage is applied to the coil terminals (A1, A2), the contactor's normally open (NO) power contacts (1-2 and 3-4) remain open. The LED indicator will be off, and the mechanical indicator will show the 'open' position.
2. Estat energitzat: When the rated 24V AC/DC control voltage is applied to the coil terminals (A1, A2), the coil energizes, causing the contacts to close. The LED indicator will illuminate, and the mechanical indicator will show the 'closed' position. This action connects the load circuit.
3. Funcionament automàtic: The contactor will maintain its energized state as long as the control voltage is present. When the control voltage is removed, the coil de-energizes, and the contacts return to their normally open position, disconnecting the load.

Monitor the LED and mechanical indicators to confirm the operational status of the contactor.

6. Manteniment

Un manteniment regular ajuda a garantir la longevitat i el funcionament fiable del contactor.

• Inspecció visual: Inspeccioneu periòdicament el contactor per detectar qualsevol signe de danys físics, decoloració o connexions soltes.
• Neteja: If necessary, gently clean the exterior of the contactor with a dry, lint-free cloth. Do not use solvents or abrasive cleaners. Ensure power is disconnected before cleaning.
• Estanquitat del terminal: Check terminal screws for tightness, especially after initial installation and during routine maintenance. Loose connections can cause overheating.
• Condicions ambientals: Assegureu-vos que l'entorn operatiu es mantingui dins dels rangs de temperatura i humitat especificats per evitar fallades prematures.

7. Solució De Problemes

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

• Contactor Not Engaging:
  • Verifiqueu que el volum de control és correctetage (24V AC/DC) is applied to terminals A1 and A2.
  • Check for loose wiring connections at the coil terminals.
  • Ensure the control circuit is complete and there are no open circuits.
  • Inspect the coil for any visible damage.
• Contacts Not Closing/Opening Properly:
  • If the coil is energized but contacts do not close, there might be a mechanical obstruction or internal fault.
  • If contacts remain closed after coil de-energization, check for contact welding due to overload or short circuit.
• Sobreescalfament:
  • Check for loose power connections, which can cause resistance and heat.
  • Ensure the load current does not exceed the 25A rating of the contacts.
  • Verify adequate ventilation around the contactor.

If issues persist after troubleshooting, contact a qualified electrician or Finder technical support.
