TECHNICAL FEATURES
DETECTION OF THE BOUNDARY WIREThe overlap distance of the lawnmower from the boundary wire is possible to set up (20 - 45cm). The lawnmower detects the boundary wire by using three area sensors.
If one of the area sensors goes beyond the boundary wire and overlap distance is reached, the lawnmower will stop instantly, movebackward and rotates until all of the sensor confirm that the lawnmower is inside of the boundary wire.

If all of the area sensor are outside from the boundary wire, the lawnmower will stop the blade motor and traction motor, alsoindicate the information on the display.

If the lawnmower cannot receive the signal from the boundary wire, the lawnmower will stop the blade motor and traction motor andindicate the information on the display until it receives the signal again.

Total length of the boundary wire should be less than 500m.

Do not make passages for lawnmower less than 1m in width.

The short cut wire ensures an expedited return to the docking station under certain circumstances.

BOUNDARY WIRE INSTALLATION

To ensure safe operation of the lawnmower, it is necessary to tune below settings with each other.

1. The optimum sensitivity (High, Middle, Low) of the lawnmower (= signal receivable range).2. The distance between the lawnmower and boundary wire when the lawnmower traces the boundary wire (=passage width).3. The shape of the zone (Zone setting).4. The Wire overlap setting.

1.The optimum sensitivity (High, Middle, Low) of the lawnmower (= signal receivable range)To setup optimum Sensitivity level (High, Middle, Low), follow below process:

a.Set the mower at the farthest location from the boundary wire.

b.Measure Area Sensor Level (page 3-35).

c.Compare measured value with below table and adjust Sensitivity level if required (page 3-43).

d.Sensitivity and Shortcut wire:

In addition to above table, adjustment may be required if you installed shortcut wire(s).

In that case, follow below table to adjust Sensitivity setting to correct value.

Note 1: Default factory setting is "Middle".

Note 2: In any case, always test the correct operation of the mower once setup is done, using Test Setup menu (page 3-35).

ZONE

CENTRE OF THE ZONE: The furthest point from each boundary wires.

BOUNDARY WIRE

Measured Value (at farthest

0No signal received. Mower cannot work without reworking boundary wire layout. Increase Sensitivity by reworking boundary wire layout to at least reach Area Sensor Lv 1, and if possible Lv 4.

1 Signal is weak, mower can lose signal. Adjust the sensitivity level to "High (page 3-43)", or increase Sensitivity by reworking boundary wire layout to reach Area Sensor Lv 4 or 5 if possible.2

34 Enough level of reception. "Middle" or "High" sensitivity level can be used (page 3-43).56 Strong signal reception and all sensitivity (High, Middle, Low) can be used. If the mower is disturbed

by external signal (e.g. another robot mower from neighbor), adjust the sensitivity level to "Low" (page 3-43).

2. The distance between the lawnmower and boundary wire when the lawnmower traces the boundary wire (=passage width)The lawnmower detects the magnetic field from the boundary wire, and moves between the boundary wire and the specified value(See below) at random as it goes toward the mowing start point ("passage width (out)" setting/page 3-30) or returns to the dockingstation ("passage return width" setting/page 3-55).The field strength varies depending on the length of the boundary wire.The field becomes weaker with a longer boundary wire, and stronger with a shorter boundary wire.With the same passage width value, passage width will vary with boundary wire length.Passage Width Out must always remain above or equal to Passage Return Width.
The below diagram shows the measuring results of the passage width in each area size at setup level (reference data).The results are measured under the specific area and it will be affected by the area shape and wire length.

3. The shape of the mowing zone.A mowing area can be divided into some zones (when using the custom mode setting).
If the mowing area is a simple shape, it is not necessary to divide the area except when the result of the performing test have failed(page 3-14).

When using the custom setting, the mowing area can be divided into a maximum to five zones.

4. The wire overlap settingWire overlap setting must be considered before installing the boundary wire.

This setting will determine minimum distance between the wire and obstacles (walls, borders etc).Default factory setting is 20cm and can be increased to 45cm.

Basic rules to be followed are:

1.Distance between boundary wire and obstacles should be 10cm larger than the wire overlap setting value.

2.Wire overlap has to be increased to 35cm minimum when a shortcut wire is installed. This will ensure mower can cross shortcutwire.

The working of each zones will be done by using below settings and timer setting.

Passage Width Out must always remain above or equal to Passage Return Width.

How to determine weekly working time*.*Working Time=Cutting Time + Return Time + Charging Time1. Two gardens, with same lawn area, will have a different weekly working time depending on following criteria.

• Field geographical position (north, east, west or south of Europe)

• Field condition-Type of grass-Boundary wire layout (Zones, Length, Shortcut Wire(s))-Slopes

2. Below table provides a rough estimation of weekly working time. Given value should be adjusted (+50% to -50%) depending on the above listed criteria.

(-) HRM300 is not designed for large areas as battery life would decrease very quickly.

3. It is advisable to visit the customer 1 or 2 months after installation to confirm that the timer settings are well defined.

• Too long working time: grass will look trampled.

• Too short working time: some small areas will remain uncut.

HOW TO READ CONNECTOR DRAWINGSConnector drawings show the terminal arrangement, terminal No., number of pins and the shape of terminal (male or female).

Both the male and female connectors are shown for the common connectors, while only the main wire harness side connectors areshown for the dedicated connectors.

The double frame connectors represent the male connectors and the single frame connectors represent the female connectors.

The gender of the connector is determined by the type of terminals the connector contains. Male connectors have male terminals.Female connectors have female terminals. Typically, the smaller plastic shell of a female connector inserts inside the larger plasticshell of a male connector when they are joined.

Terminals in a female connector are numbered from left to right, top to bottom looking at the wire side. Terminals in a maleconnector are numbered from left to right, top to bottom looking at the terminal side.

Both the male and female connectors are shown by viewing them from the terminal side.

TECHNICAL FEATURES
DETECTION OF THE BOUNDARY WIREThe overlap distance of the lawnmower from the boundary wire is possible to set up (20 - 45cm). The lawnmower detects the boundary wire by using three area sensors.
If one of the area sensors goes beyond the boundary wire and overlap distance is reached, the lawnmower will stop instantly, movebackward and rotates until all of the sensor confirm that the lawnmower is inside of the boundary wire.

If all of the area sensor are outside from the boundary wire, the lawnmower will stop the blade motor and traction motor, alsoindicate the information on the display.

If the lawnmower cannot receive the signal from the boundary wire, the lawnmower will stop the blade motor and traction motor andindicate the information on the display until it receives the signal again.

TECHNICAL FEATURES
RUNNING SPEED ADJUSTMENTTo maintain uniform blade rotation frequency the ECU monitors the current load placed on the battery.The ECU will adapt the wheel rotation speed to the load applied to the blades.
The blade rotates 360 degrees as to reduce the impact when hitting an obstruction.

If the load remains constant even when the wheel rotation stops, the ECU will stop the blade motor and exit the area.

MAKE THE "LAWN DIAGRAM"Make the "LAWN DIAGRAM" (Refer to Owner‘s Manual: 32VP7600 /page 65) and hand over to the customer and keep a sparecopy for dealer records.

This will help to ensure that any ground works in the garden can be made whilst carefully considering the boundary wire location.

• Record each measurements of the shape of the wire. • Record the zone location.

Distance between walls and boundary wire has to be adapted according to wire overlap setting (page 3-11).

Distance from the letter "N" from "HONDA" logo to the end of the short cut wires should be 80 - 85cm

SHORT CUT WIRE: TWO LINES

60 - 65 degrees

The sensitivity level setting should be high only (page 3-9).

BOUNDARY WIRE INSTALLATION

To ensure safe operation of the lawnmower, it is necessary to tune below settings with each other.

1. The optimum sensitivity (High, Middle, Low) of the lawnmower (= signal receivable range).2. The distance between the lawnmower and boundary wire when the lawnmower traces the boundary wire (=passage width).3. The shape of the zone (Zone setting).4. The Wire overlap setting.

1.The optimum sensitivity (High, Middle, Low) of the lawnmower (= signal receivable range)To setup optimum Sensitivity level (High, Middle, Low), follow below process:

a.Set the mower at the farthest location from the boundary wire.

b.Measure Area Sensor Level (page 3-35).

c.Compare measured value with below table and adjust Sensitivity level if required (page 3-43).

d.Sensitivity and Shortcut wire:

In addition to above table, adjustment may be required if you installed shortcut wire(s).

In that case, follow below table to adjust Sensitivity setting to correct value.

Note 1: Default factory setting is "Middle".

Note 2: In any case, always test the correct operation of the mower once setup is done, using Test Setup menu (page 3-35).

ZONE

CENTRE OF THE ZONE: The furthest point from each boundary wires.

BOUNDARY WIRE

Measured Value (at farthest

0No signal received. Mower cannot work without reworking boundary wire layout. Increase Sensitivity by reworking boundary wire layout to at least reach Area Sensor Lv 1, and if possible Lv 4.

1 Signal is weak, mower can lose signal. Adjust the sensitivity level to "High (page 3-43)", or increase Sensitivity by reworking boundary wire layout to reach Area Sensor Lv 4 or 5 if possible.2

34 Enough level of reception. "Middle" or "High" sensitivity level can be used (page 3-43).56 Strong signal reception and all sensitivity (High, Middle, Low) can be used. If the mower is disturbed

by external signal (e.g. another robot mower from neighbor), adjust the sensitivity level to "Low" (page 3-43).

2. The distance between the lawnmower and boundary wire when the lawnmower traces the boundary wire (=passage width)The lawnmower detects the magnetic field from the boundary wire, and moves between the boundary wire and the specified value(See below) at random as it goes toward the mowing start point ("passage width (out)" setting/page 3-30) or returns to the dockingstation ("passage return width" setting/page 3-55).The field strength varies depending on the length of the boundary wire.The field becomes weaker with a longer boundary wire, and stronger with a shorter boundary wire.With the same passage width value, passage width will vary with boundary wire length.Passage Width Out must always remain above or equal to Passage Return Width.
The below diagram shows the measuring results of the passage width in each area size at setup level (reference data).The results are measured under the specific area and it will be affected by the area shape and wire length.

3. The shape of the mowing zone.A mowing area can be divided into some zones (when using the custom mode setting).
If the mowing area is a simple shape, it is not necessary to divide the area except when the result of the performing test have failed(page 3-14).

When using the custom setting, the mowing area can be divided into a maximum to five zones.

4. The wire overlap settingWire overlap setting must be considered before installing the boundary wire.

This setting will determine minimum distance between the wire and obstacles (walls, borders etc).Default factory setting is 20cm and can be increased to 45cm.

Basic rules to be followed are:

1.Distance between boundary wire and obstacles should be 10cm larger than the wire overlap setting value.

2.Wire overlap has to be increased to 35cm minimum when a shortcut wire is installed. This will ensure mower can cross shortcutwire.

The working of each zones will be done by using below settings and timer setting.

Passage Width Out must always remain above or equal to Passage Return Width.

How to determine weekly working time*.*Working Time=Cutting Time + Return Time + Charging Time1. Two gardens, with same lawn area, will have a different weekly working time depending on following criteria.

• Field geographical position (north, east, west or south of Europe)

• Field condition-Type of grass-Boundary wire layout (Zones, Length, Shortcut Wire(s))-Slopes

2. Below table provides a rough estimation of weekly working time. Given value should be adjusted (+50% to -50%) depending on the above listed criteria.

(-) HRM300 is not designed for large areas as battery life would decrease very quickly.

3. It is advisable to visit the customer 1 or 2 months after installation to confirm that the timer settings are well defined.

• Too long working time: grass will look trampled.

• Too short working time: some small areas will remain uncut.

HOW TO READ CONNECTOR DRAWINGSConnector drawings show the terminal arrangement, terminal No., number of pins and the shape of terminal (male or female).

Both the male and female connectors are shown for the common connectors, while only the main wire harness side connectors areshown for the dedicated connectors.

The double frame connectors represent the male connectors and the single frame connectors represent the female connectors.

The gender of the connector is determined by the type of terminals the connector contains. Male connectors have male terminals.Female connectors have female terminals. Typically, the smaller plastic shell of a female connector inserts inside the larger plasticshell of a male connector when they are joined.

Terminals in a female connector are numbered from left to right, top to bottom looking at the wire side. Terminals in a maleconnector are numbered from left to right, top to bottom looking at the terminal side.

Both the male and female connectors are shown by viewing them from the terminal side.
