5. Setup jeung Instalasi

5.1 Pamasangan

The KL2622 terminal is designed for mounting on a standard 35 mm DIN rail. It should be snapped onto the DIN rail alongside a bus coupler and other Bus Terminals, ensuring proper mechanical and electrical connection.

5.2 Kabel

Before wiring, ensure all power supplies are disconnected. The KL2622 features screwless terminals for quick and secure wiring. Refer to the diagram printed on the terminal and Figure 5.1 for connection details.

Sasayogian tanaga: Connect the 230 V AC/DC power supply to the designated terminals. Ensure correct polarity if using DC.
Kaluaran 1: Connect the load for Output 1 to the corresponding terminals.
Kaluaran 2: Connect the load for Output 2 to the corresponding terminals.
Protective Earth (PE): Ensure the protective earth connection is properly made to the PE terminal, if applicable to your system.

The terminal supports 4-wire connections, meaning separate connections for the power supply and each output, allowing for independent control and isolation.

6. Operasi

Once installed and wired correctly, the KL2622 operates under the control of the connected bus coupler and the higher-level control system (e.g., PLC). The relay outputs are switched based on the digital commands received from the control system.

6.1 Indikator LED

Each output channel on the KL2622 is equipped with an LED indicator:

LED ON: Indicates that the corresponding relay output is active (closed).
LED pareum: Indicates that the corresponding relay output is inactive (open).

These LEDs provide a visual confirmation of the output status, aiding in commissioning and troubleshooting.

7. Pangropéa

The Beckhoff KL2622 is designed for maintenance-free operation. However, periodic inspection of the wiring connections and the terminal's physical condition is recommended to ensure continued reliable performance.

beberesih: If necessary, clean the exterior of the terminal with a soft, dry, lint-free cloth. Do not use abrasive cleaners or solvents.
Pariksa sambungan: Periodically verify that all wire connections are secure and free from corrosion.
Kaayaan Lingkungan: Pastikeun lingkungan operasi tetep dina kisaran suhu sareng kalembaban anu ditangtukeun.

No internal maintenance or user-serviceable parts are present. Any repairs should be handled by authorized Beckhoff service personnel.

8. Cara ngungkulan

This section addresses common issues that may arise during the operation of the KL2622 terminal.

Masalah	Mungkin Cukang lantaranana	Solusi
Output LED does not illuminate.	No power supply to the terminal. No control signal from the bus coupler. Faulty LED atawa komponén internal.	Pariksa sambungan catu daya sarta voltage. Verify the control program and bus communication. Replace the terminal if other checks fail.
Connected load does not switch.	Incorrect wiring of the load. Load current/voltage exceeds specifications. Damaged relay contact.	Inspect load wiring according to Figure 3.2. Ensure load parameters are within 2A, 230V AC/DC. If LED is on but load doesn't switch, the relay may be faulty; replace the terminal.
Terminal not recognized by bus coupler.	Improper seating on DIN rail. Damaged contacts between terminals.	Re-seat the terminal firmly on the DIN rail. Inspect the side contacts for damage.
