4. 설정 및 설치
4.1 장착
Mount the PNOZ X3P on a 35mm DIN rail in a control cabinet. Ensure adequate ventilation around the device to prevent overheating. Maintain proper clearance from heat-generating components.
4.2 전기 연결
Before making any electrical connections, ensure the main power supply is disconnected and locked out. Refer to the wiring diagrams for correct terminal assignments.
5. 배선
The PNOZ X3P supports 1-channel or 2-channel wiring for safety inputs. The choice depends on the required safety integrity level (SIL) and performance level (PL).
5.1 Input Wiring (E-STOP, Safety Gate, Light Grid)
- 1-Channel Wiring: Connect the safety device (e.g., E-STOP) to a single input channel. This configuration offers basic safety.
- 2-Channel Wiring: Connect the safety device to two independent input channels. This configuration provides redundancy and higher fault tolerance, suitable for higher safety requirements.
5.2 출력 배선
The relay provides 3 NO safety contacts for controlling power to hazardous machinery and 1 NC auxiliary contact for signaling purposes. The 1 SO (semiconductor output) can be used for diagnostic feedback to a PLC.
Ensure that the load connected to the safety contacts does not exceed the maximum switching current of 15 Amps and maximum switching voltag240볼트의 전압.

6. 사용 설명서
The PNOZ X3P operates in an automatic reset mode. Once the safety input circuit is closed (e.g., E-STOP released, safety gate closed), the safety relay will automatically energize its output contacts, provided no faults are detected.
6.1 전원 켜기
Upon applying power, the relay performs an internal self-test. If the safety inputs are closed and no faults are present, the output contacts will close, and the status indicators will illuminate.
6.2 안전 기능 활성화
When a safety input is opened (e.g., E-STOP pressed, safety gate opened), the PNOZ X3P immediately de-energizes its safety output contacts, bringing the monitored machine to a safe state.
6.3 재설정
Due to its automatic reset function, the relay will re-energize its outputs as soon as the safety input circuit is restored and no faults are present. Ensure that the machine can only restart safely after a reset.
7. 유지관리
Regular maintenance is crucial to ensure the continued safe operation of the PNOZ X3P safety relay.
- 정기 검사: Visually inspect the device and its wiring for any signs of damage, loose connections, or contamination.
- 기능 테스트: Periodically test the entire safety circuit, including the PNOZ X3P, by activating the connected safety devices (E-STOP, safety gate, light grid) to verify their proper function.
- 청소: Keep the device free from dust and debris. Use a dry, soft cloth for cleaning. Do not use abrasive cleaners or solvents.
8. 문제 해결
If the safety relay does not function as expected, consider the following common issues:
| 문제 | 가능한 원인 | 해결책 |
|---|---|---|
| Outputs do not energize after power-up. |
|
|
| Outputs de-energize unexpectedly. |
|
