Fa'amauina

The PNOZ S3 is designed for DIN rail mounting. Ensure the mounting surface is stable and free from excessive vibration. Mount the device vertically to ensure proper heat dissipation.

Uaea

Use appropriate wire gauges for all connections. The device features plug-in screw-type terminals for secure wiring. Refer to the terminal designations on the device for correct connections.

• Power Supply (24 V DC): Connect the 24 V DC supply to terminals A1 and A2.
• Inputs (S12, S22, S34): Connect safety inputs (e.g., E-STOP, safety gate contacts) to these terminals. The device supports 1-channel or 2-channel wiring.
• Outputs (13, 14, 23, 24): These are the safety outputs (Normally Open). Connect these to the control circuit of the machinery to be safeguarded.
• Auxiliary Output (Y32): This output provides status information and is not part of the safety circuit.
• Start Circuit (S11): Connect a start button or automatic start signal to this terminal, depending on the desired start mode.

Ensure all connections are tight and secure to prevent intermittent operation or safety hazards.

After completing all wiring and verifying connections, apply power to the device. The "Power" indicator light should illuminate.

Molī Fa'ailoga

Starting the Safety Function

Once all safety inputs are closed (In1, In2 lights are green), the device is ready to be started. Depending on the configuration:

• Amata Tusia: Press the connected start button. The "Start" light will illuminate, and then the "Out" light will illuminate as the safety outputs activate.
• Amata otometi: If configured for automatic start, the "Out" light will illuminate automatically once all safety inputs are closed.

To stop the safety function, activate a safety input (e.g., press E-STOP, open safety gate). The "Out" light will extinguish, and the safety outputs will de-energize.

Tausiga

The PILZ PNOZ S3 safety relay is designed for minimal maintenance. However, regular inspections are recommended to ensure continued safe operation.

• Su'ega Va'ai: Periodically check the device for any signs of physical damage, discoloration, or loose connections.
• Su'ega Galuega: Regularly test the entire safety circuit, including the PNOZ S3, by activating each safety input (e.g., pressing E-STOP, opening safety gates) to verify that the safety outputs de-energize as expected.
• Fa'amamaina: If necessary, clean the exterior of the device with a soft, dry cloth. Do not use abrasive cleaners or solvents. Ensure no dust or debris accumulates around the terminals or ventilation openings.

All maintenance and testing should be performed by qualified personnel.
