Figure 1: EUCHNER NZ1HS-3131-M Safety Switch. This image shows the safety switch with its distinctive lever arm and roller, which is used for actuation.
주요 구성 요소:
- 주택: 내부 구성품을 보호합니다.
- Lever Arm with Roller: The actuating element that detects guard position.
- 연결 포트: For electrical wiring (M20 x 1.5).
4. 설정 및 설치
Proper installation is critical for the safety switch's functionality. Follow these steps carefully:
- 설치: Securely mount the safety switch to a stable surface near the movable guard. Ensure the lever arm can be actuated freely by the guard.
- 배선:
- Disconnect all power to the machine before wiring.
- Connect the electrical wiring to the M20 x 1.5 connection port.
- Use wires with a cross-section of 0.34 to 1.5 mm2.
- Ensure connections comply with the rated voltage of 230V AC / 24V DC and current rating of 4 Amps.
- 직류 연결 시 극성이 올바른지 확인하십시오.
- 조정: Adjust the position of the switch and/or the guard so that the lever arm is actuated correctly when the guard is closed, and released when the guard is open. The switch should operate reliably throughout the guard's movement range.
- 테스트: After installation, perform a functional test to ensure the safety switch operates as intended. Verify that the machine cannot start or stops immediately when the guard is opened.
5. 사용 설명서
The NZ1HS-3131-M safety switch operates in an ON-OFF mode, designed to monitor the state of a machine guard. When the guard is closed, the lever arm is actuated, changing the state of the internal contacts (4PST, SPDT terminal). This signals to the control system that the guard is in a safe position, allowing machine operation.
When the guard is opened, the lever arm is released, causing the contacts to switch state. This action should immediately stop or prevent the start of hazardous machine functions, ensuring operator safety.
Normal Operation Sequence:
- Guard Closed: Lever arm actuated, safety circuit closed (or open, depending on specific wiring and safety logic). Machine operation permitted.
- Guard Opened: Lever arm released, safety circuit opened (or closed). Machine operation interrupted or prevented.
6. 유지관리
정기적인 유지보수는 안전 스위치의 수명 연장과 안정적인 작동을 보장합니다.
- 시각적 검사: Periodically inspect the switch for any signs of physical damage, corrosion, or wear on the lever arm and roller.
- 청소: 스위치에 먼지, 이물질, 오염물이 닿지 않도록 하십시오. 부드럽고 마른 천으로 닦으십시오. 연마성 세척제나 용제를 사용하지 마십시오.
- 기능 확인: Regularly test the switch's operation by opening and closing the guard to confirm it correctly interrupts or prevents machine operation.
- 연결 확인: 모든 전기 연결부가 단단히 고정되어 있고 부식되지 않았는지 확인하십시오.
If any damage or malfunction is detected, replace the switch immediately. Do not attempt to repair the safety switch.
