3. Vöru lokiðview

The EUCHNER NZ1HS-3131-M is a safety switch designed for monitoring the position of movable guards on machinery. It features a lever arm with a roller, providing reliable actuation. Its robust construction ensures durability in industrial environments.

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.

Lykilhlutir:

• Húsnæði: Verndar innri hluti.
• Lever Arm with Roller: The actuating element that detects guard position.
• Tengihöfn: For electrical wiring (M20 x 1.5).

4. Uppsetning og uppsetning

Proper installation is critical for the safety switch's functionality. Follow these steps carefully:

1. Uppsetning: Securely mount the safety switch to a stable surface near the movable guard. Ensure the lever arm can be actuated freely by the guard.
2. Raflögn:
   • 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.
   • Verify correct polarity for DC connections.
3. Aðlögun: 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.
4. Próf: 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. Notkunarleiðbeiningar

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:

1. Guard Closed: Lever arm actuated, safety circuit closed (or open, depending on specific wiring and safety logic). Machine operation permitted.
2. Guard Opened: Lever arm released, safety circuit opened (or closed). Machine operation interrupted or prevented.

6. Viðhald

Regular maintenance ensures the longevity and reliable operation of the safety switch.

• Sjónræn skoðun: Periodically inspect the switch for any signs of physical damage, corrosion, or wear on the lever arm and roller.
• Þrif: Keep the switch free from dust, dirt, and debris. Use a soft, dry cloth for cleaning. Avoid abrasive cleaners or solvents.
• Virkniathugun: Regularly test the switch's operation by opening and closing the guard to confirm it correctly interrupts or prevents machine operation.
• Tengingarathugun: Gakktu úr skugga um að allar rafmagnstengingar séu öruggar og lausar við tæringu.

If any damage or malfunction is detected, replace the switch immediately. Do not attempt to repair the safety switch.
