Preliminary Checks And Identification Of The Type To Be Used - V2 NYK-24V Manual Del Usuario

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:
• Your gate is equipped with a central latch.
• 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 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:
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.
