The Worx ACS (Anti-Collision System) module, model WA0860, is an accessory designed to enhance the functionality of Worx Landroid robotic lawnmowers by enabling them to detect and avoid obstacles. This system provides "eyes" to the Landroid, allowing it to navigate around objects such as trees, furniture, and other obstructions in the mowing area.
Function Description:
The ACS module utilizes automotive-grade ultrasonic sensors to detect obstacles. It is designed to identify objects taller than 20 cm and thicker than 25 mm. When an obstacle is detected, the Landroid will steer accordingly to avoid it. The system is designed for straightforward installation, and once correctly installed, the Landroid automatically recognizes the new module without requiring manual settings. The status of the ACS module is displayed on both the Landroid's app home screen and its physical display.
Important Technical Specifications:
- Model: WA0860
- Function: Obstacle avoidance
- Rated Voltage: 20V Max
- Compliance: Complies with Directives 2014/30/EU, 2011/65/EU & (EU)2015/863. Standards conform to EN 55011, EN 55014-2.
- Detection Capability: Detects objects taller than 20 cm and thicker than 25 mm.
- Compatibility: Designed for various Landroid models, including S 300 (WR130E), M 500 (WR141E), M 700 (WR142E), M 1000 (WR143E), L 1000 (WR147E), L 1500 (WR153E), and L 2000 (WR155E).
Usage Features:
- Automatic Recognition: The Landroid automatically recognizes the ACS module upon installation, requiring no manual configuration.
- App and Display Integration: The ACS module's status is visible on the Landroid app and the Landroid's onboard display. Users can activate or deactivate the ACS function via the app or display.
- Obstacle Avoidance: The primary feature is the ability to detect and avoid obstacles, improving the Landroid's navigation and preventing collisions.
- Deactivation Scenarios: The ACS module deactivates under specific conditions:
- When the Landroid is lifted or trapped.
- For a few seconds when the Landroid starts.
- When the Landroid is returning to the charging base along the boundary wire.
- When the Landroid is on its way to a mowing zone.
- For 2-8 seconds when the Landroid meets the boundary wire and bounces back.
- During rain, as large raindrops might be recognized as obstacles.
- In the presence of heavy dew in the morning.
- If the robot is raised.
- If the sensors are dirty.
- Firmware Requirement: Users should ensure their Landroid's firmware is updated to the latest version before installation for optimal performance.
- Safety Note: While the ACS can improve safety, it should not be used as a primary safety feature. The Landroid, when equipped with ACS, should not be left unattended if children, pets, or people are in the vicinity.
- Interference: The ACS is not compatible with ultrasonic devices like pet repellers, as they emit ultrasounds that can interfere with the sensors.
Maintenance Features:
- Sensor Cleaning: Regular cleaning of the ACS sensors is crucial for proper functioning. If the ACS displays an error or fails to detect obstacles, the first step is to check and clean the sensors.
- Troubleshooting: The manual provides a troubleshooting guide for common issues, such as the Landroid failing to avoid obstacles or moving abnormally. Solutions include cleaning the cover and ultrasonic sensor, checking for physical obstructions that prevent echo signals, and ensuring the module is securely installed.
- Cover Integrity: If the cover is severely deformed, it may affect performance, and contacting a service agent for replacement is recommended.
- Grass Height Consideration: If the grass height exceeds 20 cm, the ACS may detect it as an obstacle, preventing mowing in that area. In such cases, disabling the ACS function (via display or app) is recommended.
- Support: For persistent issues, users are directed to the Worx Landroid Owner's Site to access their profile and open a support ticket.
Installation Process (General Steps, specific to Landroid models):
- Turn off the Landroid.
- Remove the Landroid's cover (may involve using a screwdriver).
- Remove any inner protection or existing connectors if present.
- Plug the ACS connectors into the Landroid's designated connectors.
- Insert the ACS module into its slot.
- Arrange cables and connectors tidily.
- Secure the ACS module with the provided screws.
- Verify ACS activation on the Landroid's display or app.
The package includes the ACS module (1x), an Allen key (1x), and screws (2x) for installation.
