2) Product description and applications

ROBUS is a line of irreversible electromechanical gearmotors for the
automation of sliding gates. It is equipped with an electronic control
unit and connector for the optional SMXI or SMXIS radiocontrol
receiver. The electrical connections to external devices have been
simplified through the use of "BLUEBUS", a technique by which
several devices can be connected up using just 2 wires. ROBUS
Other products are also part of the ROBUS line, the difference of which is described in table 1.

2.1) Operating limits

Chapter 8 "Technical Characteristics" provides the only data needed
to determine whether the products of the ROBUS line are suitable
for the intended application.
The structural characteristics of ROBUS make it suitable for use on
sliding leaves in conformity with the limits indicated in table 2.
The effective suitability of ROBUS to automate a particular sliding
gate depends on the friction as well as other correlated factors, such
as ice, that could interfere with the movement of the leaf.

operates with electric power. In the event of a power failure, the
gearmotor can be released using a special key in order to move
the gate manually. Alternatively, there is the PS124 buffer battery
(optional accessory) which makes it possible to use the gate also
during the event of a power failure.

For an effective control it is absolutely vital to measure the force nec-
essary to move the leaf throughout its entire run and ensure that this
is less than half of the "nominal torque" indicated in chapter 8 "Tech-
nical characteristics" (a 50% margin on the force is recommended,
as unfavourable climatic conditions may cause an increase in the
friction); furthermore, it is necessary to take into consideration the
data indicated in table 1 to establish the number of cycles/hour,
consecutive cycles and maximum speed allowed.
