3.1 Main components for installation

The robotic system involves 4 main components:
• Product
• Charging station
• Power supply
• Loop wire
Go to the manufacturer's website or read the Operator's
manual for further descriptions about the product and
the installation.

3.2 The loop system's control signals

The loop system consists of a boundary wire and a
guide wire connected to the charging station. Some
models have several guide wires. The loop system
essentially comprises these different signals:
N
• A signal, sets the boundary for the working area.
• F signal, is generated by a loop in the charging
station so that the product knows that it is in the
vicinity of the charging station.
• N signal, is generated by a loop in the charging
station baseplate to guide the product into the
charging station so that the charging plates and the
contact plates make contact.
• Guide signal, G, leads the product to the charging
station, but can also be used to guide the product
from the charging station to a remote area.
To check the A, F, N and Guide signals, refer to the
measure the loop signal strength on page 72 .

3.3 LED indicator lamp on the charging station

The loop system's status is easily checked using the
LED indicator lamp on the charging station. Refer to
measure the loop signal strength on page 72 .

3.4 Boundary loop

The strength of the A signal varies depending on the
distance. The strength of the signal is high close to the
wire. The strength subsequently diminishes the farther
away from the wire you get. Outside the working area
the signal is negative and its strength diminishes more
rapidly. Signal quality should always be 100% for
satisfactory function.
The strength of the signal is affected by the size of the
working area, islands, headlands, passages and
corners. The signal can also be affected by magnetic
objects in the ground or in nearby walls and buildings.
Examples of magnetic objects are iron fences, iron
girders and reinforcement bars. Grass areas laid on
concrete roofs can therefore lead to a weaker signal.
The A signal's reception and amplification can vary by
+/- 10% from one product to another. This means that at
the same point in an installation, one product can
display A=90 and another one A=100. The charging
station's circuit board and the product's loop sensor can
also give certain variations between different products.
3.4.1 To test the boundary loop
The product displays the
attempt is made to start the product before the
installation is complete.
However, it is possible to test the product before the
installation is completed by doing one of the following:

3.4.2 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.
