  • Page 11: Square Mode Cutting

    1. FUNCTION 1.6 Square mode cutting This section does not apply to 210 C. Sometimes the Automower can change the mowing ® pattern and start to mow in a square pattern instead. This is called square mode cutting. The purpose of square mode cutting is to quickly get the same length of grass over the entire working area.

  • Page 12: The Loop System's Control Signals

    1. FUNCTION When an Automower ® seems to perform square mode cutting too often: • The lawn in the working area is cut very short. This means the average power is set very low and the Automower will then start square mode cutting ®...

  • Page 13: Loop Signal Strength

    1. FUNCTION F-signal = Automower in the test position ® Remote signal from the charging station which has a range of 6 – 7 metres. The signal is generated by the large coil in the charging station plate. The F-signal guides the mower in the direction of the charging station.
  • Page 14 1. FUNCTION 1.8.1 Boundary wire The signal strength on the boundary wire is constant at a loop length of up to about 500 metres (1600 ft). However, when the loop is longer than 500 metres (1600 ft), the strength can start to depreciate even if it may still be adequate.
  • Page 15 1. FUNCTION The loop signal's reception and amplification in the mower can also vary by +/- 10% from one mower to another. This means that at the same point in an installation one mower may show A=250 and another A=275. The charging station's circuit board and the mower's loop sensor can also show some variation between different machines.

  • Page 16: Corridor Width

    1. FUNCTION The strength of the signal in the guide loop is dependent on the length of the loop. Consequently, the guide loop should be as short as possible, preferably no longer than about 300 metres (1000 ft). See the picture below for examples of guide wire installation.

  • Page 17: Search Method To Find The Charging Station

    1. FUNCTION In general the widest possible corridor should always be used. Apart from a reduced risk of tracks forming, it is also easier for the Automower to follow the ® boundary wire or guide wire. The mower does not need to stop as frequently to search for the signal and with that runs more smoothly.
  • Page 18 1. FUNCTION In order to quickly test an installation, the delay times for the boundary wire and the guide wires should be 90° temporarily set to 0 minutes. Automower will not then ® make an Irregular search, but will directly start to search for the boundary wire and guide wires.

  • Page 19: Docking And Charging

    1. FUNCTION 1.11 Docking and charging This section does not apply to 210 C. When the battery level becomes too low, the Automower switches off the blade motor and starts ® to search for the charging station. When the mower receives the N-signal and enters the charging station, this is called docking.
  • Page 20 1. FUNCTION If the control box is blocked, for example, by unintentionally interrupting programming, battery charging is not monitored. It is then important that you charge the Automower with caution, that is to say, for no more than ® 10 minutes. A blocked control box is characterised by no text being shown on the display/no LEDs are lit and the keypad does not work despite the battery being charged.

  • Page 21: Sensors

    1. FUNCTION Note that the most reliable test results can be achieved when the mower is run on an installation. A new battery for 220 AC, 230 ACX and Solar Hybrid have a battery capacity of approximately 2200 mAh, and a new battery for 210 C and 260 ACX has a capacity of approximately 3000 mAh.
  • Page 22 1. FUNCTION When the Automower ® rests on a completely flat surface, the values should be around +/-3. In other cases, the tilt sensor must be calibrated (see 4.8.2 Manual test on page 68). If the mower tilts up and to the left the values will be negative.

  • Page 23: Sms Function

    1. FUNCTION The sensors cannot be deactivated, i.e. you cannot turn off the ultrasound. With a function error, the mower will run at a reduced speed. Hence, there is no way to run a 260 ACX with no ultrasound at a normal speed.

  • Page 24: Solar Panel (Solar Hybrid)

    1. FUNCTION • Activate/deactivate time-controlled sending of SMS: Move the cursor to Periodical SMS and press YES. Select YES to activate time-controlled sending of SMS, confirm with YES. Then define how often the mower should send SMS messages about its status by entering the interval in hours (e.g.

    3. INSTALLATION 3.2 Boundary wire To start an Automower requires a charging station ® and boundary wire to be installed. It is not possible to test drive a mower until the installation is complete. The Automower ® displays the fault message No loop signal when an attempt is made to start before the installation is complete.

  • Page 46: Guide Wire

    3. INSTALLATION Should the cables to and from an obstacle cross, the Automower can perceive it is outside the working ® area despite being inside the working area. Besides, if the obstacle is relatively large in relation to the working area this can affect the mower within the entire working area.
  • Page 47 3. INSTALLATION When any of the following can be found in the working area, the installation of a guide wire is recommended. • Narrow passages. In passages where the distance between the boundary wires is less than 3 metres (10 ft), it is recommended to install a guide wire through the passage.
  • Page 48 3. INSTALLATION 3.3.2 Installation of the guide wire Check that the charging station has the best placement. • Placement of the charging station and where on the boundary wire the guide wire is connected affect the length of the guide loop, see the 1.8.2 Guide loop, page 15.
  • Page 49 3. INSTALLATION If the guide wire is to be used for the Follow loop out function: • If the guide wire runs on the right, seen in the mower's direction of entry, the guide wire must be routed at least 130 cm (4 ft) straight out from the front edge of the charging plate.

  • Page 54: Installation Examples

    3. INSTALLATION 3.10 Installation examples A number of examples of settings are presented on the following pages. Each installation has been assessed according to the scale: • Non approved installation • Approved installation • Fully approved installation. Example number 1 This installation is not approved if Corridor width 10 is used.
  • Page 55 3. INSTALLATION Example number 2 In this example the guide loop is longer than 300 metres (1000 ft). There is a risk that the Automower ® stops following the guide wire. The charging station should therefore be moved. Non approved 2m (6.5ft) 3m (10ft) 2m (6.5ft)
  • Page 56 3. INSTALLATION Example number 3 In this example different exit angles have been set. Automower ® will easily reach all parts of the working area. The risk of tracks forming is less with these settings compared with allowing the mower to follow the boundary wire out of the charging station.
  • Page 57 3. INSTALLATION finds the charging station easily from Area 1. On the other With the help of a guide wire, the Automower ® hand, there is a risk of the mower not finding its way out of the area if it does not find the guide wire and start to follow it before the delay time for the boundary wire has elapsed.
  • Page 58 3. INSTALLATION In the figure below, the charging station is placed in a corresponding position in Area 2. The guide loop will then be shorter than 300 metres (1000 ft). By increasing the corridor width for the boundary wire the mower, when searching, will run past several passages instead of running through them.
  • Page 59 3. INSTALLATION Example number 7 In this example Automower ® , with the help of the settings, will reach the entire working area. Fully approved 3m (10ft) 3m (10ft) Follow loop Boundary wire Guide wire Follow loop out Area 1 Area 2 Delay 11 minutes...
  • Page 60 3. INSTALLATION By adopting another charging station placement it will be easier to install a guide wire and make a guide loop that is shorter than 300 metres (1000 ft).
