ZCS NEXTTECH LX2 - User Manual

This document describes the Ambrogio robot Twenty Deluxe and Twenty Elite models, which are battery-powered automatic lawnmower robots designed to trim grass in gardens and house lawns. They are small, compact, silent, and easy to transport.

Function Description

The robot automatically trims grass within a delimited area using a perimeter wire. It operates randomly, changing direction when it detects the perimeter wire or an obstacle. The robot can recognize areas with higher or thicker grass and activate a spiral movement for a perfect finish. It can be programmed to work on multiple areas (primary and secondary) depending on the model's specifications.

Usage Features

Installation:

• Requires preliminary planning for charging station placement and perimeter wire layout.
• Charging station should be on a level, compact, and stable ground, preferably in the widest part of the lawn, with a straight area of 200 cm (78.74") in front.
• Perimeter wire can be laid on the ground with pegs or buried (2-3 cm deep, max 5 cm).
• Perimeter wire installation direction is clockwise, and counter-clockwise around flowerbeds.
• Minimum passage allowed between perimeter wires is 70 cm (27.56").
• Obstacles like pavements or driveways at lawn level require the perimeter wire to be 5 cm (1.96") from the edge. For metal objects, the distance should be at least 20 cm (7.87") to prevent interference.
• Obstacles like kerbs, walls, flower beds, hedges, or plants with protruding roots require the perimeter wire to be at least 20 cm (7.87") away.
• For pools, ponds, ravines, ditches, steps, or public roads, the perimeter wire should be at least 90 cm (35.43 inches) from the edge.
• Slopes greater than allowed limits cannot be mowed; the perimeter wire should exclude these areas.
• The robot can return to the charging station using two methods: "On the Wire" (for complex gardens with many obstacles) or "V-Meter" (for quicker re-entry). "Recall on the Wire" is a special positioning for narrow passages.

First Use and Operation:

• On first use, the robot batteries must be charged for at least 4 hours.
• The robot can be operated in manual mode (AUTO LED off) or automatic mode (AUTO LED on).
• In manual mode, press START/PAUSE to begin a work cycle. The robot returns to the charging station when the battery is exhausted.
• In automatic mode, the robot works daily according to a programmed schedule, exiting the charging station for work cycles and returning to recharge as needed.
• The robot has a built-in Bluetooth device for programming and control via a smartphone app (Android and iOS). The app allows changing working times, rain sensor operation, departure points for secondary areas, password, and sending commands.
• The factory PIN is "0000" and should be changed for security.

Programming Mode:

• Up to 4 working schedules (T1, T2, T3, T4) can be set for each day, including start/end times and mowing areas.
• "Edge cutting" function enables the robot to cut along the lawn edge, recommended at least twice a week.
• Rain sensor can be set to ON (returns to charging station when rain detected), DELAY (returns and stays for a set time), or OFF.
• Up to 4 work areas can be configured, with adjustable size (set to 0 m² to disable).
• General settings include PIN CODE protection, connectivity parameters, charging station alignment correction factor, and resetting factory settings.
• The robot's distance from the perimeter wire before changing direction can be set (MIN, MAX, MED).

Safety Devices:

• Obstacle detector: Bumper sensor stops movement and initiates backward motion when a solid object >10 cm (3.94") is hit.
• Inclinometer: Stops the cutting blade if the robot works on a slope steeper than the maximum limit or tips over.
• Emergency stop switch: "STOP" button on the upper part of the robot immediately stops movement and blade rotation.
• Over-current protection: Monitors motors for overheating. If wheel motor overheats, the robot attempts to move in the opposite direction; if persistent, it stops and signals an error. If the cutting blade motor overheats, the robot performs maneuvers to unblock the blade or stops and signals a motor error.
• No signal sensor: Stops the robot automatically if no signal is detected.

Safety Regulations:

• Read the manual carefully before use.
• Ensure no children, elderly, disabled people, or pets are in the working area during operation.
• Supervise the device in working areas not bounded by a fence.
• Place "Warning! Automatic lawnmower! Keep away from the machine! Supervise children!" signs in public areas.
• Not suitable for use by children or people with reduced capabilities without supervision.
• Do not allow untrained people to use the robot.
• Operators performing maintenance/repair must be fully conversant with safety regulations.
• Never remove, bypass, or tamper with safety devices.
• Check the lawn for toys, tools, branches, clothing, or other objects that could damage blades.
• Never sit on, lift, or place hands/feet under the robot while it's running.
• Do not use the robot when a sprinkler system is running.
• Do not wash the robot with high-pressure water jets or immerse it in water.
• Disconnect power and activate safety device before any adjustment or maintenance. Wear protective gloves when handling the cutting blade.
• Do not perform cleaning/maintenance by unsupervised children.
• Replace damaged cutting blades or external parts.
• If the power cord of the transformer is damaged, have it replaced by the manufacturer or authorized service center.
• If the power cord is damaged during use, press "STOP" and disconnect from the electrical socket.
• Regularly check the blade, mounting screws, and cutting mechanism for wear or damage.
• If the robot vibrates abnormally, press "STOP" and disconnect power.
• Never use or recharge the robot in explosive/flammable environments.
• Use only the supplied battery charger and power supply unit.
