Note! In the event of a boundary wire signal error

If the error indicator light ashes red on, there is an error

in the boundary wire signal:

• Theboundarywireistoolong(over250m).

• Theboundarywireisassembledincorrectly,there

is moisture in a joint, or an incorrect connector has

been used.

• TheboundarywiremustNOTbestrippedwhenrst

using the connector provided.

• Youcanremovetheendsoftheboundarywirefrom

the charging station and measure the resistance

of the boundary wire using a multimeter. A new

boundary wire has a resistance of about 2 Ohm per

100 metres.

If the boundary wire’s resistance measures more

than 8-10 Ohm, the robot lawnmower will display a

boundary wire signal error.

• Youcancreateatestcircuitusingapprox.10metres

of boundary wire to check that the robot lawnmower

is working properly. Remember to remove the ends

of the real boundary wire from the charging station

rst.

Correct the error or replace the boundary wire.

If the indicator light ashes green and there is a break in

the boundary wire, you must join the two broken ends

of the boundary wire using a connector. Cut the ends of

the boundary wire cleanly using side-cutting pliers and

insert the ends into the connector WITHOUT stripping

them rst. Press the connector fully together using

at-nose pliers so that the internal metal plate goes

through the boundary wire’s insulation and recreates

the connection.

Once the indicator light turns green, the boundary wire

has probably been installed and connected properly,

unless the robot lawnmower displays a boundary wire

signal error. Check that all the plastic pegs are knocked

fully into the ground and that the boundary wire is taut

and at against the ground right the way round.
