4. Impostazione

4.1 Montaggio

The RT6 safety relay is designed for DIN rail mounting. Ensure the DIN rail is securely fastened within the control cabinet. Snap the relay onto the DIN rail by hooking the top edge first, then pressing down until it clicks into place.

4.2 Cablaggio

AVVERTIMENTO: Ensure all power is disconnected before wiring. Incorrect wiring can lead to equipment damage or personal injury.

1. Refer to the wiring diagram provided on the side of the unit or in the detailed technical documentation for specific terminal connections.
2. Connect the 24V DC power supply to the designated power input terminals.
3. Connect safety input devices (e.g., emergency stop buttons, light curtains) to the safety input terminals.
4. Connect the safety outputs to the controlled devices (e.g., contactors, motor starters).
5. Assicurarsi che tutti i collegamenti siano sicuri e adeguatamente isolati.

4.3 Accensione iniziale

After completing all wiring, apply power to the system. Observe the diagnostic LEDs on the front panel. The power LED should illuminate, and other LEDs will indicate the status of the safety inputs and outputs.

5. Operativo

5.1 Funzionamento di base

The RT6 safety relay operates automatically once correctly configured and powered. When all safety inputs are closed (i.e., no safety function is active), the safety outputs will activate, allowing the controlled machinery to operate. If any safety input opens, the safety outputs will immediately de-energize, bringing the machinery to a safe state.

5.2 Spie luminose

The front panel features several LEDs to indicate the relay's status:

• LED di potenza: Illuminates when the relay receives power.
• LED di ingresso: Indicate the status of the safety input channels (e.g., green for active, off for open).
• LED di uscita: Indicates the status of the safety outputs (e.g., green for active, off for de-energized).
• LED di guasto: Illuminates or flashes to indicate a fault condition within the relay or the safety circuit. Refer to the troubleshooting section for fault codes.

5.3 Procedure di ripristino

After a safety function has been activated (e.g., an emergency stop button pressed), the safety relay typically requires a manual or automatic reset before the safety outputs can be re-energized. The reset method depends on the relay's configuration:

• Ripristino manuale: Press the designated reset button on the control panel after the safety circuit is restored.
• Ripristino automatico: The relay automatically resets once the safety circuit is restored. This mode is generally used for specific applications and requires careful risk assessment.

6. Manutenzione

Regular maintenance ensures the continued reliable operation of the ABB RT6 Safety Relay.

6.1 Programma di ispezione

• Mensile: Ispezionare visivamente il relè per individuare eventuali segni di danni fisici, scolorimento o collegamenti allentati.
• Annualmente: Perform a functional test of the safety circuit, including the relay, by activating each safety input device (e.g., pressing E-stop, breaking light curtain beam) and verifying that the safety outputs de-energize.

6.2 Pulizia

ATTENZIONE: Scollegare l'alimentazione prima della pulizia.

Clean the exterior of the relay with a soft, dry cloth. Do not use abrasive cleaners or solvents, as these can damage the housing. Ensure no dust or debris accumulates around the terminals or ventilation openings.
