Opsætning og installation
Follow these steps for proper installation of the Idec RH2B-UL-AC110-120V Relay:
- Strømafbrydelse: Ensure all power to the circuit is completely disconnected before beginning installation.
- Montering: The relay is designed for DIN Rail mounting. Securely attach the relay to a standard DIN rail in your control panel.
- Ledningsføring: The relay utilizes through-hole connectors. Carefully connect the control circuit wiring to the coil terminals and the load circuit wiring to the contact terminals. Refer to the wiring diagram (if available in your system documentation) for specific terminal assignments.

Betjeningsvejledning
The Idec RH2B-UL-AC110-120V Relay operates automatically based on the control signal applied to its coil. When the specified AC voltage (110-120V) is applied to the coil, the relay contacts will switch, opening or closing the connected load circuit. When the voltage is removed, the contacts return to their original state.
- Ensure the control signal is within the specified voltage-serien for pålidelig drift.
- Observe any indicator lights on the relay (if present) to confirm coil energization.
Opretholdelse
The Idec RH2B-UL-AC110-120V Relay is designed for long-term, reliable operation with minimal maintenance. However, periodic inspection is recommended:
- Visuel inspektion: Periodically check the relay for any signs of physical damage, discoloration, or loose connections.
- Rensning: Rengør om nødvendigt forsigtigt relæets yderside med en tør, blød klud. Brug ikke opløsningsmidler eller slibende rengøringsmidler.
- Kontaktinspektion: In critical applications, inspect contacts for pitting or wear. Replace the relay if significant wear is observed.
- Miljøforhold: Sørg for, at driftsmiljøet forbliver inden for de angivne temperatur- og fugtighedsområder for at forhindre for tidlig fejl.
Fejlfinding
If the relay is not functioning as expected, consider the following common issues:
| Problem | Mulig årsag | Løsning |
|---|---|---|
| Relæspolen aktiveres ikke. | No power to coil, incorrect voltage, faulty wiring, or damaged coil. | Check power supply, verify voltage (110-120V AC), inspect wiring connections, test coil continuity. |
| Kontakterne skifter ikke. | Coil not energizing, contacts welded, or mechanical failure. | Refer to "Relay coil does not energize" solutions. If coil is good, replace relay. |
| Load not receiving power. | Relay contacts not closing, open circuit in load wiring, or faulty load. | Verify relay operation. Check load circuit wiring and the load itself. |
If troubleshooting steps do not resolve the issue, contact Idec technical support or a qualified electrician.
