• Power Supply: Connect 24VDC to the designated power terminals (e.g., A1, A2).
• Inputs: Connect safety-related input devices (e.g., emergency stop buttons, safety gates) to the input terminals (e.g., S12, S22, S32, S44).
• Outputs: Connect controlled devices (e.g., contactors, valves) to the output terminals (e.g., 14, 24, Y6, Y7, Y32, Y33, Y5).

Verify all wiring before applying power to the system.

5. Operating Instructions

5.1 Power On

Once wiring is complete and verified, apply 24VDC power to the safety relay. The 'POWER' LED indicator should illuminate, indicating the device is receiving power.

5.2 Status Indicators

The device features LED indicators to display its operational status:

• POWER LED: Indicates the presence of operating voltage.
• CH.1 LED: Indicates the status of safety channel 1.
• CH.2 LED: Indicates the status of safety channel 2.

Refer to the specific product documentation for detailed interpretation of LED states (e.g., steady on, flashing) which typically indicate normal operation, fault conditions, or input states.

6. Maintenance

The PNOZ e5.13p safety relay is designed for minimal maintenance. However, regular inspections are recommended to ensure continued safe operation.

• Visual Inspection: Periodically check the device for any signs of physical damage, loose connections, or discoloration.
• Cleaning: Keep the device free from dust and debris. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
• Functional Testing: Perform periodic functional tests of the safety circuit as required by relevant safety standards and regulations.

7. Troubleshooting

If the safety relay does not function as expected, consider the following troubleshooting steps:

• No Power LED: Check the 24VDC power supply and its connections to the relay. Ensure the power source is active.
• Faulty Channel LED: If a channel LED indicates a fault (e.g., flashing rapidly), inspect the associated safety input devices and their wiring for breaks, short circuits, or incorrect operation.
• Outputs Not Activating: Verify that all safety inputs are in their safe state, and the reset conditions (if applicable) have been met. Check the wiring to the controlled devices.
• Unexpected Shutdown: Review the system's safety logic and ensure all safety devices are functioning correctly. An unexpected shutdown often indicates a triggered safety function.

If issues persist after basic troubleshooting, consult a qualified technician or contact customer support.
