5. Installation og opsætning

The NLQ3-125/4P ATS is designed for track installation and is compatible with PZ30 power distribution boxes. Before proceeding with installation, ensure all power is disconnected at the main breaker.

Installationstrin:

1. Inspektion: Before installation, carefully inspect the ATS for any signs of damage. Use the operating handle to manually switch it on and off to check the flexibility of the transmission mechanism. Verify the generation and disconnection conditions of the load at each stage for both normal and standby power supplies.
2. Montering: Mount the ATS securely onto a DIN rail within your PZ30 power distribution box or suitable enclosure.
3. Wiring Main Power (Source A): Connect the main power supply (Normal Power) to the terminals labeled 'Source A'. Ensure correct phase (R, S, T) and neutral (N) connections for 4-pole systems.
4. Wiring Standby Power (Source B): Connect the standby power supply (Generator) to the terminals labeled 'Source B'. Ensure correct phase (R, S, T) and neutral (N) connections.
5. Ledningsbelastning: Connect the load (your electrical system) to the output terminals of the ATS.
6. Styreledninger: Connect any necessary external control signals to the AR, AN, NC, C1, OFF (for Source A) and BR, BN, NC, C1, OFF (for Source B) terminals as per your system requirements.
7. Verifikation: Double-check all wiring for correctness and tightness. Ensure no loose connections are present.

Miljøforhold:

• Omgivelsestemperatur: Maximum 40°C, minimum -5°C. The average temperature within 24 hours should not exceed 35°C.
• Højde: Installation site altitude should not be higher than 2000m.
• Relativ luftfugtighed: At 40°C, relative humidity should not exceed 50%. At -5°C, higher humidity is permissible (e.g., 90% at 25°C). Special measures may be needed to address occasional condensation due to temperature changes.

6. Betjeningsvejledning

The NLQ3-125/4P ATS offers both automatic and manual operation modes.

Automatisk tilstand:

• Set the selector switch to the 'Auto' position.
• In this mode, the ATS will continuously monitor the main power supply (Source A).
• If Source A fails or becomes abnormal, the ATS will automatically switch to the standby power supply (Source B) within milliseconds.
• When Source A is restored and stable, the ATS will automatically switch back to Source A.
• The indicator lights (A or B) will show which power source is currently active.

Manuel tilstand:

• Set the selector switch to the 'Manual' position.
• In manual mode, the user can manually switch between Source A and Source B using the operating handle.
• Denne tilstand bruges typisk til test, vedligeholdelse eller i situationer, hvor automatisk skift ikke er ønsket.
• Note: Ensure the manual operation is performed carefully and safely, especially when power is connected.

7. Vedligeholdelse

Regelmæssig vedligeholdelse sikrer din ATS' levetid og pålidelige drift.

• Periodisk eftersyn: Annually inspect the ATS for any signs of wear, damage, or loose connections.
• Rensning: Hold enheden ren og fri for støv og snavs. Brug en tør, blød klud til rengøring. Brug ikke flydende rengøringsmidler.
• Terminaltjek: Periodically check all terminal screws to ensure they are tight and secure.
• Funktionstest: Regularly test the automatic switching function by simulating a main power failure (if safe to do so) to ensure the standby power engages correctly.
• Professionel service: For any complex issues or internal repairs, contact a qualified electrician or service technician.

8. Fejlfinding

This section addresses common issues you might encounter with your ATS.

Issue: ATS does not switch automatically.

• Tjek tilstand: Ensure the selector switch is set to 'Auto' mode.
• Strømforsyning: Verify that both main (Source A) and standby (Source B) power supplies are connected and functional.
• Styreledninger: Inspect control wiring for any disconnections or faults.
• Intern fejl: If all external checks are clear, there might be an internal fault. Contact a qualified technician.

Issue: No power to load.

• Indgangseffekt: Check if both Source A and Source B have power.
• Kontaktposition: Ensure the ATS is switched to an active power source (either A or B, indicated by lights).
• Udgangsledning: Inspect the wiring from the ATS output to the load for any breaks or loose connections.
• Overbelastning/Kortslutning: Check for any overload or short circuit conditions in your electrical system that might have tripped protective devices upstream.

Issue: ATS makes unusual noises.

• Løse komponenter: Disconnect power and check for any loose internal components or mounting screws.
• Interne skader: If the noise persists and cannot be identified, it may indicate internal damage. Seek professional assistance.
