Preliminary Checks And Identification Of The Type To Be Used - V2 STERN600 Instructions De Montage

1.2 - PRELIMINARY CHECKS AND IDENTIFICATION OF THE TYPE TO BE USED

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 door must be suitable to be automated (check the door operation manual and directions). The door structure itself must be stout
and appropriate to be automated.
• Check the door to be provided with anti-fall system (independent of the suspension system).
• The door must be functional and safe.
• The door must open and close easily without any friction.
• The door must be properly balanced both before and after its automation: stopping the door in any position, it must not move
(carry out a balance weight adjustment, if necessary)..
• Fix the engine steadily and using suitable material.
• If necessary, make the structural calculation and enclose to the technical specification paper.
• It is advisable to install the geared motor in the centre of the door; it is permitted to move aside 100 mm to install the sliding arm
accessory 162504.
• In case of counterbalanced door, check that the minimum distance between the track and the door must not be under 20 mm
Warning: The minimum safety level depends on the type of use; please refer to the following outline:
TYPE OF ACTIVATION
COMMANDS
Man-present command
Remote control and closure in
view (e.g. infrared)
Remote control and closure not
in view (e.g. radio)
Automatic control
(e.g. timed closure control)
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.
