GEYA Mini ATS Dual Power Automatic Transfer Switch Instruction Manual

1. Introducció

The GEYA Mini ATS (Automatic Transfer Switch) is designed to ensure a continuous power supply by automatically switching between a normal power source and a spare (backup) power source. This device is primarily used to detect the status of both power sources. If the normal power supply becomes abnormal, the switch will automatically transfer to the spare power, minimizing interruptions. When the normal power supply is restored, the switch will revert to it. This unit is suitable for household orbit-type installations and is commonly used in PZ30 power distribution boxes for dual power grids operating at 50/60Hz.

The GEYA Mini ATS is characterized by its compact structure, reliable transfer mechanism, ease of installation and maintenance, and long operational lifespan.

2. Informació de seguretat

ADVERTÈNCIA: Perill de descàrrega elèctrica. La instal·lació i el manteniment només els ha de dur a terme personal qualificat.

• Always disconnect power from both normal and backup sources before installation, inspection, or maintenance.
• Assegureu-vos que totes les connexions de cablejat siguin segures i que compleixin els codis elèctrics locals.
• Comproveu el voltage and current ratings of the switch match your application requirements.
• No feu funcionar l'interruptor si sembla que està danyat.
• The input power supply sequence must be connected correctly to ensure proper operation.

Figure 3.2: Conceptual diagram of the GEYA ATS in an uninterruptible power supply setup. It shows how the switch connects between a normal power source (e.g., grid city power) and a backup power source (e.g., AC generator, inverter) to supply power to the load.

4. Configuració i instal·lació

This device is designed for DIN rail mounting within a PZ30 power distribution box. Follow these steps for proper installation:

1. Muntatge: Securely attach the ATS to a standard DIN rail.
2. Cablejat: Connect the normal power source to terminals labeled (I) and the backup power source to terminals labeled (II). Connect the load to the terminals labeled LOAD. Ensure the neutral wire is connected to the 'N' terminal and the live wire to the 'A' terminal for each input and output.
3. Voltage Selecció: Assegureu-vos que el volum correctetage model is used for your system. For 2P 25A 220V models, this is suitable for 220V/400V systems or single-line 220V applications.
4. Connexions de terminals: The terminal wiring area accommodates 1 to 25mm² wires. Use an M5 screw for connections and tighten to a torque of 2.5 N.m.

Figure 4.2: Guide for choosing the correct voltage model. It specifies that 2P 220V models are for 220V/400V systems or single-line 220V, and 2P 110V models are for 110V/220V systems or single-line 110V. Incorrect voltage can damage the control circuit.

5. Instruccions de funcionament

The GEYA Mini ATS offers both automatic and manual operation modes.

• Mode automàtic: Set the switch to 'Auto'. In this mode, the device continuously monitors both power sources. If the primary (normal) power fails or drops below acceptable levels, the switch will automatically transfer the load to the secondary (backup) power source. When the primary power is restored, the switch will automatically revert the load back to the primary source.
• Mode manual: Set the switch to 'Manual'. In this mode, you can manually select between power source I and power source II using the operation handle. This mode is useful for testing or specific maintenance scenarios.

Nota important: While the transfer time is fast (typically less than 50ms), it may not be instantaneous enough for highly sensitive electronic equipment like computers to remain powered without a momentary interruption. For such applications, an additional Uninterruptible Power Supply (UPS) may be required for the sensitive load.

6. Manteniment

Regular maintenance ensures the longevity and reliable operation of your GEYA Mini ATS.

• Inspecció visual: Periodically inspect the switch for any signs of physical damage, loose connections, or overheating.
• Estanquitat del terminal: Check and re-tighten all terminal screws as necessary to prevent arcing and ensure good electrical contact.
• Neteja: Keep the switch free from dust and debris. Use a dry, soft cloth for cleaning. Do not use liquid cleaners.
• Prova de funcionalitat: Regularly test the automatic transfer function by simulating a power outage on the primary source (if safe to do so and with appropriate precautions).

7. Solució De Problemes

If you encounter issues with your GEYA Mini ATS, consider the following:

• No Transfer:
  • Check if both power sources (Normal and Backup) are active and within acceptable voltagrangs e.
  • Ensure the switch is set to 'Auto' mode.
  • Verifiqueu que totes les connexions de cablejat siguin segures i correctes segons el diagrama.
  • Confirm the control voltage is within the rated operating voltage (85%-110% of 220V AC).
• Partial Power/Intermittent Operation:
  • Inspect for loose terminal connections.
  • Check for signs of overheating or damaged wiring.
• Switch Does Not Stay in Position:
  • If in manual mode, ensure the handle is fully engaged.
  • If in auto mode, this could indicate an issue with the internal mechanism or control circuit.

If problems persist after basic troubleshooting, contact qualified electrical personnel or GEYA customer support.
