4. Настройка и инсталация

4.1 Монтаж

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 Електрически връзки

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. Окабеляване

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 Output Wiring

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 voltage от 240 волта.

6. Инструкции за работа

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 Включване

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 Safety Function Activation

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 Нулиране

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. Поддръжка

Regular maintenance is crucial to ensure the continued safe operation of the PNOZ X3P safety relay.

• Периодична проверка: Visually inspect the device and its wiring for any signs of damage, loose connections, or contamination.
• Функционален тест: 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.
• Почистване: Keep the device free from dust and debris. Use a dry, soft cloth for cleaning. Do not use abrasive cleaners or solvents.

8. Отстраняване на проблеми

If the safety relay does not function as expected, consider the following common issues:

If troubleshooting steps do not resolve the issue, contact PILZ technical support.
