2.1) Operating limits
Chapter 8 “Technical Characteristics” provides the data needed to determine whether ROAD200 components are suitable for the intended
application.
In general, ROAD200 is suitable for the automation of gates featuring leaves up to 5 m wide and weighing up to 200 kg, as shown in Tables
1 and 2.
The length of the leaf makes it possible to determine both the maxi-
mum number of cycles per hour and consecutive cycles, while the
weight makes it possible to determine the reduction percentage of
the cycles and the maximum speed allowed. For example, if the leaf
is 3.8 m long it will be possible to have 15 cycles/hour and 10 con-
secutive cycles. However, if the leaf weighs 170 Kg, they must be
reduced to 70%, resulting in 11 cycles/hour and approximately 7
consecutive cycles.
The control unit has a limiting device which prevents the risk of
overheating based on the load of the motor and duration of the
cycles. This device triggers when the maximum limit is exceeded.

2.3) List of cables
Figure 2 shows the cables needed for the connection of the devices
in a typical installation; table 3 shows the cable characteristics.
The cables used must be suitable for the type of installation;
for example, an H03VV-F type cable is recommended for indoor
applications, while H07RN-F is suitable for outdoor applications.
!
Note 1:
power supply cable longer than 30 m may be used provided it has a larger gauge, e.g. 3x2.5mm
2
, and that a safety grounding sys-
tem is provided near the automation unit.
Note 2:
A single 4x0.5mm
2
cable can be used instead of two 2x0.5mm
2
cables.
Note 3:
Please refer to Chapter “7.3.1 STOP Input” in situations where there is more than one edge, for information about the type of con-
nection recommended by the manufacturer.
Note 4:
special devices which enable connection even when the leaf is moving must be used to connect movable edges to sliding leaves.
