7.2 Other Operational or Fault Problems
Wire disconnected from switch

leads are firmly attached
Perimeter wire cut
Walk along perimeter, including
islands and obstacles excluded with
the perimeter wire and look for
obvious cuts or breaks in the wire.
Repair with Robomower wire splice
connectors.

Check and repair all loose/poor or
corroded connections

Perimeter wire too long for one zone
A maximum perimeter wire length of
1000 feet (300 m) is recommended.
Areas requiring longer lengths
should be broken into separate
zones. If the ‘Cut Wire’ indicator
flashes once when the Perimeter
Switch is activated, this confirms a
length too long for a single
perimeter zone.
Batteries are completely discharged. Install fresh alkaline C-cell batteries
Batteries installed with wrong polarity
position.
Verify correct placement of
batteries.

vertically and exposed to water/rain.
Water/moisture protection of the
