PRELIMINARY CHECKS AND IDENTIFICATION OF THE TYPE TO BE USED
The automation device should not be used until installation, as specified in “Testing and start-up”, has been performed.
It should be remembered that the device does not compensate for defects caused by improper installation, or poor maintenance, thus,
prior to proceeding with installation, ensure that the structure is suitable and meets current standards and, if necessary, perform any
structural modifications aimed at the implementation of safety gaps and the protection or segregation of all crushing, shearing and transit
zones, and verify that:
• The gate has no friction points, either during closing or opening.
• The gate is well balanced, i.e. there is no tendency to move spontaneously when stopped in any position.
• The position identified for fixing the motor reducer allows easy and safe manual manoeuvring, compatible with the
size of the motor reducer itself.
• The gate shall be equipped with central and side stops, which are fundamental for the good system operation
• The support on which the automation device will be fixed is solid and durable.
• The mains power supply to which the automation device is connected has a dedicated safety earthing system and
differential breaker with tripping current less than or equal to 30 mA (the breaker gap distance should be greater than
or equal to 3 mm).
Warning: The minimum safety level depends on the type of use; please refer to the following outline:
Group 1 -
Only a limited number of people are authorised for use, and closure is not in a public area. Examples of this type are gates inside
business premises, where the sole users are employees, or a part of them who have been suitably informed.
Group 2 -
Only a limited number of people are authorised for use, but in this case, closure is in a public area. An example of this may be a
company gate that accesses onto a public street, and which is only used by employees.
Group 3 -
Anyone can use the automated closure, which is thus located on public land. For example the access gate to a supermarket or an
office, or a hospital.
Protection A -
Closure is activated by means of a control button with the person present, i.e. with maintained action.
Protection B -
With the person present, closure is activated by a command controlled by means of a key-switch or the like, in order to
prevent use by unauthorised persons.
Protection C -
Restricts the force of the leaf of the door or gate. I.e., in the case of the gate striking an obstacle, the impact force must fall
within a curve established by the regulations.
Protection D -
Devices, such as photocells, capable of detecting the presence of people or obstacles. They may be active on just one side or
on both sides of the door or gate.
Protection E -
Sensitive devices, such as footboards or immaterial barriers, capable of detecting the presence of a person, and installed in
such a way that the latter cannot be struck in any way by a moving leaf or panel. These devices should be active within the entire “danger
zone” of the gate. The Machinery Directive defines “Danger Zone” as any zone surrounding and/or near machinery where the presence of
an exposed person constitutes a risk to the health and safety of that person.
The risk analysis should take into consideration all danger zones for the automation device, which should be appropriately
protected and marked.
In a clearly visible area, apply a sign with information identifying the motorised door or gate.
The installer should provide the user with all the information relating to automatic operation, emergency opening and
maintenance of the motorised door or gate.
