BEFORE INSTALLING THE MOTORS
1- Ensure perfect right angles of the gate hinges to enable
totally smooth and balanced swing gate movement.
Otherwise the motor may be damaged when subject to
much higher levels of resistance with respect to the tho-
se specified for intended use.
2-
The MT/C2 motor is equipped with internal mecha-
nical stops adjustable by means of a special screw
(see adjustment of internal mechanical stops) to
enable adjustment of the gate closing and opening
stop points.
In any event, the installer must position
the mechanical end stops for gate opening and closing
for system safety purposes - see Fig. 2 -.
3- The installation of the mechanical end
stops for gate opening and closing is neces-
sary for system safety purposes.
4- The motor is supplied with the mobile pin (PM) - Fig. 3 -
in the correct position for installation. However, ensure
that the distance of the mobile pin from the rear connec-
tion point is:
735 mm
.
Any distance greater than the above can cau-
se shutdown of the motor shortly before the
gate reaches the closing end stop; any di-
stance less than the above will cause a smal-
ler opening angle than required.
5) Choose the opening angle and calculate the
distances B, C (see Fig. 4 Fig. 5 and table) for
positioning of brackets. The values in the grey band
are recommended. The brackets can be resized
(shortened or lengthened) according to assembly
requirements, taking care to observe distances B
and C.
N.B. In the case of outward opening, the overall working
area of the gate is reduced due to the dimensions of the
motors. In this case installation of the motors on the upper
section of the gate is recommended.
IMPORTANT: failure to observe distances B and C
specified in the table will mean that the gate starts
movement suddenly with excessive oscillations,
which could lead to damage to the brackets and motor.
