The top-right diagram illustrates the internal schematic with coil terminals A1, A2 and contact terminals 11 (common), 12 (normally closed), 14 (normally open). The bottom diagrams provide side and front views with overall dimensions (e.g., 29mm length, 25mm height, 12.4mm width, 0.4mm and 1mm pin thickness).

5. Installation

The Finder 40.31.9.024.0000 relay is designed for through-hole mounting on a Printed Circuit Board (PCB). Follow these steps for proper installation:

1. Forbered printkortet: Ensure the PCB has correctly sized holes and pad layouts matching the relay's pin configuration as shown in Figure 4.1.
2. Insert the Relay: Carefully align the relay pins with the corresponding holes on the PCB. Ensure the relay is oriented correctly.
3. Loddeforbindelser: Solder each pin to its respective pad on the PCB. Use appropriate soldering techniques to ensure strong, reliable electrical and mechanical connections. The relay terminals are designed for soldering.
4. Spoleforbindelser: Connect the 24VDC power supply to the coil terminals A1 and A2. Polarity is typically indicated on the relay or in the schematic (A1 positive, A2 negative for DC coils, but check specific markings).
5. Kontaktforbindelser: Connect the load circuits to the contact terminals:
   • Terminal 11: Fælles kontakt.
   • Terminal 12: Normally Closed (NC) contact. This contact is closed when the coil is de-energized.
   • Terminal 14: Normally Open (NO) contact. This contact is closed when the coil is energized.
6. Bekræft installationen: After soldering, visually inspect all connections for shorts, cold solder joints, or other defects.

6. Betjening

The Finder 40.31.9.024.0000 relay operates by energizing its 24VDC coil. When the coil is energized, an electromagnetic field is created, which pulls the armature, causing the common contact (11) to switch from the Normally Closed (12) position to the Normally Open (14) position. When the coil is de-energized, the armature returns to its original state, and the common contact (11) reconnects with the Normally Closed (12) contact.

• Coil Voltage: Apply 24VDC to terminals A1 and A2 to activate the relay.
• Kontaktskift: The relay provides a mechanical switch action, isolating the control circuit (coil) from the load circuit (contacts).
• Belastningskapacitet: Ensure the switched load does not exceed 10 Amps at 250VAC. Exceeding these limits can damage the relay and connected equipment.

7. Vedligeholdelse

The Finder 40.31.9.024.0000 relay is a sealed component and generally requires minimal maintenance. However, periodic inspection can help ensure its longevity and reliable operation:

• Visuel inspektion: Regularly check for any signs of physical damage, discoloration, or overheating on the relay body and terminals.
• Miljøforhold: Ensure the operating environment remains within specified temperature and humidity ranges. Protect the relay from excessive dust or corrosive atmospheres.
• Forbindelsesintegritet: Periodically verify that all soldered connections remain secure and free from corrosion.
• Rensning: Rengør om nødvendigt forsigtigt relæets yderside med en tør, blød klud. Brug ikke opløsningsmidler eller slibende rengøringsmidler.

8. Fejlfinding

Hvis relæet ikke fungerer som forventet, skal du overveje følgende fejlfindingstrin:

• Relæ aktiveres ikke:
  • Check if the correct 24VDC is applied to coil terminals A1 and A2.
  • Verify coil current (nominal 27mA).
  • Inspect for open circuits in the coil wiring.
  • Sørg for, at strømforsyningen fungerer korrekt.
• Belastning skifter ikke:
  • Confirm the relay coil is activating (a faint click might be audible).
  • Check continuity across the contact terminals (11-12 and 11-14) when the coil is energized and de-energized.
  • Verify that the load circuit is correctly wired to the common (11) and desired NO (14) or NC (12) contacts.
  • Sørg for belastningsstrømmen og voluminiumstallettage do not exceed the relay's contact ratings.
• Overophedning:
  • This indicates excessive current or voltage. Immediately disconnect power.
  • Recheck all circuit parameters against the relay's specifications.

If issues persist after troubleshooting, consider replacing the relay or consulting a qualified technician.
