6. Operating Modes
The device supports three operating modes: self-locking, interlocking, and inching (micromotion). These modes can typically be configured within the eWeLink app or via physical buttons on the device, depending on the specific model variant.
- Self-locking Mode: Each channel operates independently. Pressing the button (or app control) turns the relay ON, pressing it again turns it OFF.
- Interlocking Mode: When one channel is turned ON, all other channels are automatically turned OFF. This is useful for applications where only one device should be active at a time.
- Inching (Micromotion) Mode: The relay turns ON for a set duration (e.g., 0.5 seconds to 1 hour) and then automatically turns OFF. This is suitable for momentary actions like garage door openers or pulse controls.
