2. 설정 및 설치

Proper installation is crucial for the safe and effective operation of the Lifeline 4 switch. Always ensure power is disconnected before beginning installation.

2.1 장착

• Mount the switch securely to a rigid surface using appropriate fasteners. Ensure the mounting location allows for clear access to the cable and reset mechanism.
• Consider the maximum cable length of 75 meters when positioning the switch to ensure effective coverage of the hazard area.

2.2 배선

The switch is equipped with screw terminals for electrical connections. It features 2 Normally Open (NO) and 2 Normally Closed (NC) contacts.

• Connect control circuit wiring to the designated screw terminals. Refer to the wiring diagram provided with the product for specific terminal assignments.
• Utilize the M20 conduit entries for secure and protected cable routing.
• Ensure all connections are tight and properly insulated to prevent short circuits or electrical hazards.

2.3 Cable Tensioning

The Lifeline 4 switch incorporates a visual indicator for correct cable tension. This is critical for reliable operation.

• Attach the pull cable to the eyelet at the top of the switch.
• Tension the cable until the indicator aligns with the "TENSIONED" mark. Avoid over-tensioning, which can damage the switch or cable.
• If the indicator shows "SLACK", the cable is too loose and may not activate the switch reliably. Adjust tension until the "TENSIONED" state is achieved.

3. 사용 설명서

The Lifeline 4 switch operates by detecting a pull or slackening of the attached cable.

3.1 정상 작동

• When the cable is correctly tensioned and the switch is in its "RUN" state, the connected machinery can operate.

3.2 Activating the Switch (Emergency Stop)

• To activate the emergency stop function, pull the cable firmly at any point along its length. This action will cause the switch contacts to change state, initiating a stop command to the connected machinery.
• Alternatively, the switch can be activated by the cable becoming slack, for example, due to a break in the cable.

3.3 스위치 재설정

• After activation, the switch must be manually reset before machinery can be restarted.
• Locate the red emergency stop button and the blue reset lever on the switch housing.
• To reset, ensure the cable is properly tensioned, then push the red button and/or operate the blue lever as indicated on the device until the switch returns to its "RUN" position.
• Verify that the cable tension indicator shows "TENSIONED" before attempting to restart machinery.

4. 유지관리

Regular maintenance ensures the longevity and reliable operation of your Lifeline 4 Cable Pull Switch.

• 시각적 검사: Periodically inspect the switch housing, cable, and mounting for any signs of damage, wear, or corrosion.
• Cable Tension Check: Regularly verify that the cable tension indicator remains in the "TENSIONED" position. Adjust as necessary.
• 기능성 테스트: Perform routine functional tests by activating the switch (pulling the cable) and verifying that the connected machinery stops as intended. Then, practice resetting the switch.
• 청소: Keep the switch free from excessive dust, dirt, and debris. Use a soft, damp 청소용 천을 사용하세요. 연마성 세제나 용제는 사용하지 마세요.
• 사이: 모든 전기 연결부가 단단히 고정되어 있고 부식되지 않았는지 확인하십시오.
