1. Introducció
The GEYA G2R-63 Automatic Transfer Switch (ATS) is a PC class infrequent change-over switch designed for AC systems with AC 50-60Hz and rated current 6A-63A. It features a two-station design, typically used for a common power supply (A) and a backup power supply (B). Its primary function is to automatically switch to the backup power supply when the main power fails, ensuring uninterrupted power to the load. The switching speed is less than 50 milliseconds.
When both power sources A and B are available, the device prioritizes the common power supply (A).

6. Instruccions de funcionament
The GEYA G2R ATS supports both manual and automatic operation modes.
6.1. Mode manual
In manual mode, you can manually switch between the two power sources using the selector switch.
- Ensure both power sources are turned on.
- Set the selector switch to "Manual".
- Manually toggle the switch to select either power source (I) or (II) to supply power to the load.
Important Note on Manual Operation:
- Manual operation allows for electrical switching, but the speed of operation by users can vary.
- Excessive silver alloy loss is possible during manual operation if not performed carefully.
- The selector switch should only be moved to the manual position after all power has been cut off, typically for inspection and maintenance.
6.2. Automatic Mode
In automatic mode, the ATS will automatically detect power failures and restore power, switching between the main and backup supplies.
- Set the selector switch to "Auto".
- When the main power supply (I) is disconnected, the product will automatically switch to the backup power supply (II).
- When the main power supply (I) is restored, the product will automatically switch back to the main power supply.
Important Note on Automatic Mode:
- The control circuit is immediately energized when the selector switch is in the electric (Auto) position.
- The internal switch is designed to handle the changeover. The coil can operate normally within 85%-110% of the rated operating voltage.
- Vol d'entrada massa baixtage may cause the coil to overheat and burn out.
6.3. Sobrevoltage i Undervoltage Protecció
The G2R ATS includes built-in voltage protection features:
- If the main power supply voltage cau per sota del undervoltage threshold (e.g., 175V for 220V systems), the ATS will automatically switch to the backup power supply.
- If the main power supply voltage s'eleva per sobre de l'overvoltage threshold (e.g., 260V for 220V systems), the ATS will automatically switch to the backup power supply.
- Un cop el voltage returns to normal range (e.g., above 195V for undervoltage recovery, below 240V for overvoltage recovery), the ATS will switch back to the main power supply.
Nota:
When abnormal voltage returns to normal voltage, the indicator light flashes for 15 seconds (with a delay of 15 seconds) and then returns to normal light. The power supply of this circuit will only be considered normal in the chip judgment after 15 seconds. Switch between primary and backup logic again.

8. Solució De Problemes
If you encounter issues with your GEYA G2R ATS, refer to the following common troubleshooting steps:
| Problema | Causa possible | Solució |
|---|---|---|
| Load not receiving power in Auto mode. | Both main and backup power supplies are off, or one is outside voltage llindars. | Check both power sources. Ensure voltages are within normal operating range. Verify indicator lights. |
| Indicator light flashing for Common/Backup power supply. | Vol anormaltage (per sota o per sobre del voltage) detected on that power supply. | Consulteu el voltage of the indicated power supply. The ATS will switch to the other source if available. It will return to normal after 15 seconds if voltage s'estabilitza. |
| Device not switching automatically. | Selector switch is in "Manual" mode. | Switch the selector to "Auto" mode. |
| Device feels hot or smells burnt. | Control coil overheating due to low input voltage or internal fault. | Immediately disconnect all power. Do not operate. Contact a qualified electrician for inspection and repair. |
9. Consells d'usuari
- Solar Power Integration: Yes, this ATS can be used with solar power systems. Connect your inverter output (from solar panels, MPPT, and batteries) to one of the power inputs (e.g., as the backup power source). Ensure the inverter is a pure sine wave type and has a power output above 2000W for optimal performance.
- Priorització: Remember that when both power sources are available, the ATS is designed to prioritize the common power supply (Source A).
