4. 설정 및 설치

4.1 장착

The PNOZ/X7/24VAC/DC is designed for DIN rail mounting. Ensure adequate ventilation around the device.

1. Mount the safety relay on a standard 35mm DIN rail in a control cabinet.
2. Ensure secure fastening to prevent vibration.

4.2 배선

Refer to the wiring diagram below for correct connection. All connections must comply with local electrical codes.

그림 2: Close-up of the PILZ PNOZ/X7/24VAC/DC terminals. The top terminals are A1 (power input), 13, and 23 (safety outputs). The bottom terminals are A2 (power return), 14, 24 (safety outputs), and Y1, Y2 (feedback loop/reset). This view highlights the screw terminals for electrical connections.

• Power Supply (24VAC/DC): Connect the positive supply to terminal A1 and the negative/neutral to terminal A2.
• Input Circuit (E-Stop/Safety Gate): Connect the safety device (e.g., E-stop button) across terminals Y1 and Y2. For 1-channel wiring, ensure the circuit is closed when the safety device is active.
• 출력 접점: Terminals 13-14 and 23-24 are normally open (NO) safety contacts. Connect these to the control circuit of the machinery to be controlled.
• 피드백 루프: For automatic reset, the feedback loop (Y1-Y2) must be closed.

중요한:

Always verify wiring against the specific application requirements and the detailed wiring diagrams provided in the full product documentation from PILZ.

5. 사용 설명서

The PNOZ/X7/24VAC/DC operates with an automatic reset function. Once the safety circuit is closed and the input conditions are met, the output contacts will close automatically.

5.1 전원 켜기

1. 모든 배선이 올바르고 안전하게 연결되어 있는지 확인하십시오.
2. Apply 24VAC/DC power to terminals A1 and A2.
3. The "POWER" LED indicator will illuminate.

5.2 정상 작동

• When the safety input (e.g., E-stop released, safety gate closed) is active, the "CH.1/CH.2" LED will illuminate.
• The safety output contacts (13-14, 23-24) will close, allowing the machine to operate.

5.3 안전 기능 활성화

• If the safety input is interrupted (e.g., E-stop pressed, safety gate opened), the "CH.1/CH.2" LED will extinguish.
• The safety output contacts (13-14, 23-24) will open immediately, bringing the machine to a safe stop.

5.4 Automatic Reset

Once the safety input condition is restored (e.g., E-stop released, safety gate closed), the PNOZ/X7/24VAC/DC will automatically reset, and the output contacts will close again, provided no faults are detected.

6. 유지관리

The PILZ PNOZ/X7/24VAC/DC safety relay is designed for minimal maintenance. Regular inspections are recommended to ensure continued safe operation.

6.1 정기 점검

• 시각적 검사: Periodically check the device for any signs of damage, discoloration, or loose connections.
• 기능 테스트: Regularly test the entire safety circuit, including the E-stop buttons and safety gates, to ensure the safety relay correctly de-energizes the outputs.
• LED 표시등: Verify that the "POWER" and "CH.1/CH.2" LEDs illuminate and extinguish as expected during operation and safety function activation.

6.2 청소

If cleaning is necessary, disconnect power and use a soft, dry cloth. Do not use abrasive cleaners or solvents.

주의:

Do not attempt to open or repair the device. Refer all servicing to authorized personnel.
