Attēla apraksts: Sānu view of the PILZ PNOZ S3 safety relay, showcasing its distinctive yellow and black housing. The top section features two sets of terminals, labeled 'EX' and 'LX', indicating expansion and input connections. Below these, a row of terminals is visible, marked 'A1', '13', '23', 'S12', 'S22', and 'S34', which are typically used for power supply and safety inputs. The side panel of the unit clearly displays the product name 'PILZ PNOZ S3' and a vertical array of indicator lights. These lights are labeled 'Power', 'In1', 'In2', 'Out', 'Start', and 'Fault', providing visual feedback on the relay's operational status. At the bottom, another set of terminals is present, labeled 'S11', 'S21', 'Y32', 'A2', '14', and '24', which are typically for safety outputs and auxiliary connections. The overall design emphasizes a compact, industrial-grade construction with clear labeling for ease of installation and monitoring.

Uzstādīšana un uzstādīšana

Montāža

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.

Elektroinstalācija

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.

Darbība

Sākotnējā ieslēgšana

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

Indikatora gaismas

Table 1: Indicator Light Status
Indikators	Statuss	Apraksts
Jauda	Zaļš (IESL.)	Ierīce ir ieslēgta.
In1, In2	Zaļš (IESL.)	Safety inputs are closed (e.g., E-STOP released, safety gate closed).
Ārā	Zaļš (IESL.)	Safety outputs are active (relay contacts closed).
Sākt	Zaļš (IESL.)	Start condition met (e.g., start button pressed, automatic start enabled).
Vaina	Red (ON/Flashing)	Indicates an internal fault or wiring error. Refer to troubleshooting.

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:

Manuāla iedarbināšana: Press the connected start button. The "Start" light will illuminate, and then the "Out" light will illuminate as the safety outputs activate.
Automātiskā palaišana: 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.

Apkope

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

Vizuāla pārbaude: Periodically check the device for any signs of physical damage, discoloration, or loose connections.
Funkcijas pārbaude: 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.
Tīrīšana: 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.

2. tabula: Traucējummeklēšanas rokasgrāmata
Problēma	Iespējamais cēlonis	Risinājums
"Power" light is off.	Nav barošanas avota vai nepareizs skaļumstage.	Check 24 V DC power supply to terminals A1/A2. Verify voltage.
"In1" or "In2" light is off when inputs should be closed.	Open safety input circuit (e.g., E-STOP pressed, safety gate open, wiring error).	Check continuity of safety input devices and wiring to S12, S22, S34. Ensure all safety devices are in their safe (closed) state.
"Out" light does not illuminate after start attempt.	Safety inputs not closed, start condition not met, or internal fault.	Verify "In1" and "In2" lights are green. If manual start, ensure start button is pressed and "Start" light illuminates. Check "Fault" light.
"Fault" light is red.	Internal device fault, short circuit in input wiring, or incorrect wiring.	Disconnect power, re-check all wiring according to the manual. If fault persists, the device may be defective.
