CHARACTERISTICS OF THE OPERATOR
1.0 GENERAL CHARACTERISTICS
•
ZT 4
is a
hydraulic swing gate operator
, specially designed for residential use.
• The ZT 4 operator, if installed correctly, conforms to the current safety standards.
List of versions:
C:
Hydraulic lock for closing only (with lock inaccessible when the gate is open)
SF:
No hydraulic lock - braking action (the gate leaf can be moved by hand with a minimum of resistance, if moved slowly; there is also a
release device to facilitate opening -needs an electric lock)
•
The
C
version, with hydraulic closing lock, does not require the use of the electric lock and keeps gate leaves of less than 1.8
m in closed position.
•
The emergency release (to be used in the event of a power failure) is safe to use and easily manoeuvrable and enables the user to move the
gate by hand using the triangular key provided. The release is easily accessible via a hatch on the upper cover of the operator.
•
Safety against entrapment risks is guaranteed by sensing valves, settable during installation.
1.1 TECHNICAL DATA
Warning
!
The noise le
vel of the above models, referred to the working of the operator, independently of the gate leaf and the post, falls
within the maximum limits set by EEC standards.
1.2 CHOOSING THE TYPE OF AUTOMATION
Before mounting, choose the type of automation on the basis of the characteristics and dimensions of the element to be operated.
Caution
•
The choice of the most suitable type of automation assures an effi cient operation of the unit and minimises the possibility
of failures.
Warning
!
• The versions listed above are also recommended for use with solid gate leaves (with the operator inaccessible when
the gate is open).
• The C version model, suitable for use in windy areas, must not be fi tted to gate leaves of up to 1.8 m.
Warning
!
The peripheral speed of the gate leaf must always fall within the limits of the current safety regulations. Also, it is important
to avoid the use of high-speed operators on wide gate leaves, as this could cause the leaves to bang violently against the
gate stop (see the “Technical Data” table).
