6. Үйл ажиллагаа

The TOQ6-63PV offers both automatic and manual operation modes.

6.1. Үйлдлийн горимууд

• Авто горим: When the selector switch is set to "Auto", the device will automatically detect the presence and quality of both power sources (City Power and PV Grid-connected) and switch to the preferred or available source. Typically, it prioritizes one source (e.g., PV) and switches to the other (e.g., City Power) if the primary source fails or is out of specification.
• Гар горим: When the selector switch is set to "Manual", you can manually select the desired power source using the toggle switch (I or II).
  • I байр суурь: Selects Power Source 1 (PV Grid-connected).
  • II байр суурь: Selects Power Source 2 (City Power).

6.2. Заагч гэрэл

• IU (Red LED): Indicates the status of Power Source 1 (PV Grid-connected). Lit when Power Source 1 is active.
• IIU (Green LED): Indicates the status of Power Source 2 (City Power). Lit when Power Source 2 is active.
• Load ON (Red LED): Indicates that power is being supplied to the load. Lit when the load is receiving power from either source.
