4. Iestatīšana un instalēšana

4.1 Montāža

The PNOZ/X7/24VAC/DC is designed for DIN rail mounting. Ensure adequate ventilation around the device.

1. Mount the safety relay on a standard 35mm DIN rail in a control cabinet.
2. Ensure secure fastening to prevent vibration.

4.2 Elektroinstalācija

Refer to the wiring diagram below for correct connection. All connections must comply with local electrical codes.

2. attēls: Close-up of the PILZ PNOZ/X7/24VAC/DC terminals. The top terminals are A1 (power input), 13, and 23 (safety outputs). The bottom terminals are A2 (power return), 14, 24 (safety outputs), and Y1, Y2 (feedback loop/reset). This view highlights the screw terminals for electrical connections.

• Power Supply (24VAC/DC): Connect the positive supply to terminal A1 and the negative/neutral to terminal A2.
• Input Circuit (E-Stop/Safety Gate): Connect the safety device (e.g., E-stop button) across terminals Y1 and Y2. For 1-channel wiring, ensure the circuit is closed when the safety device is active.
• Izvades kontakti: Terminals 13-14 and 23-24 are normally open (NO) safety contacts. Connect these to the control circuit of the machinery to be controlled.
• Atsauksmju cilpa: For automatic reset, the feedback loop (Y1-Y2) must be closed.

SVARĪGI:

5. Lietošanas instrukcijas

The PNOZ/X7/24VAC/DC operates with an automatic reset function. Once the safety circuit is closed and the input conditions are met, the output contacts will close automatically.

5.1. Ieslēgšanās

1. Pārliecinieties, vai visa elektroinstalācija ir pareiza un droša.
2. Apply 24VAC/DC power to terminals A1 and A2.
3. The "POWER" LED indicator will illuminate.

5.2 Normāla darbība

• When the safety input (e.g., E-stop released, safety gate closed) is active, the "CH.1/CH.2" LED will illuminate.
• The safety output contacts (13-14, 23-24) will close, allowing the machine to operate.

5.3 Safety Function Activation

• If the safety input is interrupted (e.g., E-stop pressed, safety gate opened), the "CH.1/CH.2" LED will extinguish.
• The safety output contacts (13-14, 23-24) will open immediately, bringing the machine to a safe stop.

5.4 Automatic Reset

Once the safety input condition is restored (e.g., E-stop released, safety gate closed), the PNOZ/X7/24VAC/DC will automatically reset, and the output contacts will close again, provided no faults are detected.

6. Apkope

The PILZ PNOZ/X7/24VAC/DC safety relay is designed for minimal maintenance. Regular inspections are recommended to ensure continued safe operation.

6.1 Regulāras pārbaudes

• Vizuāla pārbaude: Periodically check the device for any signs of damage, discoloration, or loose connections.
• Funkcijas pārbaude: Regularly test the entire safety circuit, including the E-stop buttons and safety gates, to ensure the safety relay correctly de-energizes the outputs.
• LED indikatori: Verify that the "POWER" and "CH.1/CH.2" LEDs illuminate and extinguish as expected during operation and safety function activation.
