    1. FUNCTION 1.4 Introduction This Technical handbook contains important information about the mower and its function, how you install it and several installation examples. It also contains information about special menu functions in the mower, the service program Autocheck, repair instructions and fault tracing.

  • Page 9: Technical Data

    (0.6 acre +/- 20 %) mowing three times a week 1.6 Mower program Automower™ The behaviour of the Husqvarna Automower™ is controlled by a microprocessor and software. The software, the mower program, manages all information and the operation of the mower.
  • Page 10 The edition states how new the mower program is. Husqvarna works constantly to improve the behaviour and performance of the mower, which results in new program editions. The program type provides information about which type of mower program Automower is programmed with.

  • Page 11: Mowing Technique

    1. FUNCTION 1.7 Mowing technique The Automower mowing system is based on an efficient and energy saving principle. Unlike many traditional lawn mowers, Automower cuts the grass instead of striking it off. Mowing in different weather We recommend you allow the Automower to mainly mow in dry weather to obtain the best possible result.

  • Page 12: Square Mode Cutting

    1. FUNCTION Irregular mowing pattern The Automower mows the lawn in an irregular pattern. This gives a very even mowing result. In addition, there are no distinctive tracks left in the lawn, which is often the case when using a conventional lawn mower.

  • Page 13: The Loop System's Control Signals

    1. FUNCTION each night it will never, in principle, perform square mode cutting. The instantaneous power consumption to maintain the speed of the blade disc must deviate from the average power by the set factor (e.g. 50 %). Consequently, the lawn in one area must always be longer/thicker than before.
  • Page 14 1. FUNCTION F-signal (only 220 AC, 230 ACX and Solar Hybrid) = 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 15: Loop Signal Strength

    1. FUNCTION 1.10 Loop signal strength This section only applies to 220 AC, 230 ACX and Solar Hybrid. 1.10.1 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 16 1. FUNCTION always available along the entire length of the boundary wire. 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.

  • Page 17: 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 200 metres (700 ft). See the picture below for examples of guide wire installation.

  • Page 18: 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 19 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 20: Docking And Charging

    1. FUNCTION Depending on the placement of the charging station, F = 25 (4 m, 13 ft) the Automower may be forced to leave the F-field to reach the charging station. The mower then follows the boundary wire out of the F-field. First it runs 10 metres (30 ft) from the F-field in one direction bearings before it turns and follows the boundary wire...
  • Page 21 1. FUNCTION 1.14.1 Battery check If the mower's battery starts to deteriorate the Automower will mow for shorter periods. The mower can also stop and display the fault message Low battery voltage (Does not apply to 210 C). A battery check is recommended in order to establish whether the battery is spent (For 210 C it is sufficient to run the mower as usual).

  • Page 22: The Solar Panel On Solar Hybrid

    1. FUNCTION IMPORTANT INFORMATION Note that the threshold value of 1500 mAh is purely a guide value and that the battery capacity can vary from mower to mower. As long as the mower can mow the lawn the battery does not need replacing. When replacing the battery, you should reset Trip Op.

  • Page 43: Installation

    3.1 Charging station The placement of the charging station should be well planned in order to give the best installation and function of the Husqvarna Automower™: • The charging station should have a central placement in the working area, so that the Automower can find it as soon as possible.

  • Page 44: Boundary Wire

    3. INSTALLATION Loop generator/charger (only 210C) should be installed as the transformer above. The ends of the boundary wire are run in parallel and close to each other, in towards the loop generator/charger. • If you use a guide wire the charging station must be placed so that the overall guide loop is not too long.
  • Page 45 3. INSTALLATION Obstacles Obstacles are demarcated by routing the boundary wire from the outer edge of the working area in towards the object, around it and then back along the same path under the same staples. The distance between the wires on the return route should be as small as possible.

  • Page 46: Guide Wire

    3. INSTALLATION 3.3 Guide wire This section only applies to 220 AC, 230 ACX and Solar Hybrid. 3.3.1 Need of a guide wire With the help of a guide wire Automower can quickly and easily find the charging station by following the guide wire instead of searching irregularly or by following the boundary wire.
  • Page 47 3. INSTALLATION • The boundary wire runs across a long slope (steeper than 10 %). When Automower follows the boundary wire across a slope (steeper than 10 %) the mower must compensate for the slope. The mower must stop relatively often to check the strength of the loop signal and then follow the boundary wire at a slower speed.
  • Page 48 3. INSTALLATION If you shall install the guide wire through a passage: • Automower follows the guide wire on the same side of the wire both to and from the charging station. This means that in towards the charging station the guide wire is on the right side of the mower and away from the charging station the guide wire is on the left side of the mower.

  • Page 49: Testing The Installation

    3. INSTALLATION • If the guide wire runs on the left, seen in the mower's direction of entry, the guide wire must be routed at least 2 m (6.5 ft) from the front edge of the charging plate. In this instance, Automower will find it difficult to find the low loop signal strengths, i.e.
  • Page 50 3. INSTALLATION Repeat steps 1 to 4 until you find the maximum corridor width. IMPORTANT INFORMATION When Test IN (3-2-4) is used, the house icon on the display will come on and the mower will remain in the charging station. Press the Home button to return to operations.

  • Page 51: Problems Following Out

    3. INSTALLATION Place Automower in the charging station and select Test OUT (3-2-5). The mower will now leave the charging station directly according to the stated direction. The distance will be shown on the display, stated in metres, as the mower runs. Stop the mower after the required distance and read the distance.

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 200 metres (700 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) 3012-621...
  • 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 Example number 4 In this example a Corridor width 0 is required for the mower to pass through the passage. This setting requires the boundary wire to be at least 40cm (16”) inside the working area, which the passage is too narrow for.
  • Page 58 3. INSTALLATION Example number 5 In this example the guide loop is longer than 200 metres (700 ft). There is a risk that the Automower stops following the guide wire. The charging station should therefore be moved. Non approved 3m (10ft) 3m (10ft) 1m (3ft) 3012-628...
  • Page 59 3. INSTALLATION Example number 6 In this example the charging station is placed by an island. The easiest way to reach Area 1 is with the help of the Exit angles function. The working area contains many islands, which results in long search times. By increasing the corridor width for the boundary wire, the search times are reduced, as the mower will then run past unnecessary passages.
  • Page 60 3. INSTALLATION Example number 8 In this example Corridor width 1 is required for the mower to pass through the passages. The installation is approved, but can be designed better. Both another charging station placement and a guide wire are recommended.
