Over-heat Monitoring Protection
The blade motor and each of the two wheel drive motors are monitored continuously during operation for any
situation that may cause these motors to over-heat. In such event, Robomow will stop operation of at least
that motor and possibly the mower itself and indicate that the motor is cooling down. While unusual, this may
happen when the mower is on grass that is severely overgrown; the underside of the mower is clogged from
poor cleaning maintenance; the mower has encountered an obstacle that is unable to activate the bumper
sensor preventing it from moving; or a problem landscape area has caused the mower to get stuck and is
preventing it from moving.
How It Works
A small wire, called the perimeter wire, is placed around the perimeter of the lawn and any other areas
where you
do not want the mower to enter. A small signal is generated from a device attached to the
perimeter wire, called the
Perimeter Switch. When turned on, this signal is carried through the perimeter
wire, creating what we define as a
virtual wall.
The virtual wall is visible only to Robomow, keeping
Robomow where you want it, on your lawn. The
perimeter switch must be turned on to activate the
perimeter wire before Robomow will operate.
